Floor Plan Cost Intelligence SaaS for Independent Auto Dealers
AFC, the floor plan lending arm of OPENLANE, posted a 22.1% return on tangible equity in 2024 while originating 1,012,000 loans to independent car dealers. NextGear Capital, owned by Cox Automotive, floored another 175,000+ vehicles per year across 24,000 dealer accounts. Between the two of them, they extracted roughly $500 million in annual interest and fees from dealers who had no tool to benchmark whether their rate was competitive, no system to track per-vehicle carrying cost in real time, and no data to tell them which car on the lot was bleeding money faster than it could sell.
The Problem
Independent used car dealers sold 9.8 million vehicles in 2025, according to the National Independent Automobile Dealers Association, their third consecutive year of growth. These aren't the gleaming franchise stores with manufacturer support and captive finance arms. They're the 35,000 to 40,000 lots scattered across strip malls and highway frontage roads, each typically carrying 30 to 200 vehicles financed through a mechanism called floor plan lending. The dealer borrows money to buy cars at auction, pays interest every day the car sits unsold, and repays the principal when it sells. Floor plan lending is the oxygen supply of independent auto retail.
The economics are punishing and getting worse. A dealer who buys a $25,000 vehicle on a floor plan at 9% APR pays $6.16 per day in interest on that single unit. At 60 days to sell, that's $370 in carrying cost, eating 14.8% of a typical $2,500 gross profit. Scale that across 20 vehicles on the lot and you're looking at $7,400 per month in floor plan interest alone, or $88,800 per year before you've paid rent, payroll, or reconditioning costs. And days-to-sell has been climbing: BCG's 2025 dealer survey found that average days to sell rose from 30 in early 2023 to nearly 60 in 2024, with 38% of surveyed dealers reporting that higher interest rates "severely or significantly impacted" their floor-planning costs.
The independent dealer's floor plan relationship is structured almost identically to the way subprime borrowers relate to credit card companies, except with less transparency. The lender sets the rate. The lender decides the credit line. The lender runs physical lot checks (called "curtailments") to verify the collateral is still on site. The dealer, meanwhile, has exactly zero visibility into what other dealers are paying for the same product. There is no published benchmark. No comparison tool. No Bankrate for floor plan financing. A dealer in Phoenix paying prime plus 5% has no way to know that a dealer with identical volume and credit in Dallas is paying prime plus 3%. The lenders know. The dealers don't. That gap has a name in every other financial market: information asymmetry. Here, it's just called Tuesday.
Market Size
Lender-side revenue establishes the floor. OPENLANE's SEC filings show AFC generated $287.9 million in finance revenue in the first nine months of 2024 (comprising $176.6 million in interest income and $141.5 million in fee income), with $1.55 billion in gross obligations outstanding at year-end. NextGear Capital, which does not file separately but discloses through Cox Automotive, serves 24,000+ dealers and processes 175,000+ transactions annually; industry estimates place its outstanding portfolio at $3 to $4 billion, roughly double AFC's. Add Ally Dealer Financial Services, Westlake Financial, and the regional banks and credit unions that serve smaller operators, and the total independent dealer floor plan market carries an estimated $8 to $12 billion in outstanding balances at any given time, generating $1.5 to $2.5 billion annually in interest and fee revenue.
The addressable dealer count: NIADA reports 9.8 million independent dealer sales in 2025. Assuming the average active independent dealer sells 250 to 350 vehicles per year, the active dealer population is roughly 28,000 to 39,000 operations. Not all use floor plan financing; cash buyers and BHPH dealers with internal financing represent perhaps 30 to 40% of the total. That leaves an addressable market of 17,000 to 27,000 independent dealers who carry floor plan debt and would benefit from cost intelligence tools.
At $299/month for a Standard tier (per-vehicle cost tracking, curtailment calendar, aging alerts) and $699/month for a Premium tier (rate benchmarking, acquisition optimizer, disposition recommendations), with a 60/40 split, the blended ARPU is $459/month. At 22,000 addressable dealers, the TAM is $121 million in annual recurring revenue. Year 3 target: 1,800 subscribers at blended $459/month = $9.9 million ARR.
The Product
A floor plan cost intelligence platform that gives independent dealers the same financial visibility that franchise dealer groups build with CFO teams and enterprise DMS systems. Four modules:
- Per-vehicle carrying cost tracker: The moment a vehicle is floored, the clock starts. This module calculates the real daily cost of holding each unit: floor plan interest (based on the dealer's actual rate and the specific advance amount), insurance accrual, lot rent allocation, and opportunity cost of the tied-up credit line. It produces a live dashboard showing each VIN's cumulative carrying cost, projected break-even margin (the minimum gross profit needed to cover accumulated carrying costs), and a red-yellow-green signal indicating whether the unit is profitable to hold. When a vehicle's projected break-even exceeds the estimated retail gross based on current market comps, the system flags it for wholesale disposition, often before the dealer realizes they've been feeding a losing trade for three weeks
- Rate benchmarking engine: Participating dealers contribute their floor plan terms (rate, fee schedule, credit line, curtailment schedule) to an anonymized data pool. In return, they see where their terms rank against dealers of similar size, volume, geography, and credit tier. This is the STR model applied to floor plan lending: you share your rate to see the market. The output: a percentile ranking for each major term component, an estimated annual cost difference between the dealer's current terms and the 25th-percentile benchmark (the rate achievable by a competitively positioned dealer), and a one-page rate negotiation brief the dealer can bring to their lender or a competing lender
- Acquisition optimizer: Before the dealer bids at auction, this module estimates the total cost of ownership for a specific vehicle: projected floor plan interest based on estimated days-to-sell (modeled from historical data on similar make/model/year/mileage/geography combinations), estimated reconditioning cost, and projected retail gross. The output is a maximum bid recommendation that accounts for carrying cost, not just the spread between buy price and retail price, which is the only calculation most dealers run. A $2,500 spread on a vehicle that will sit for 90 days at $18/day in carrying cost is actually a $880 net profit, not $2,500. This module makes that visible before the hammer falls
- Curtailment and payoff optimizer: Floor plan lenders typically require periodic principal reductions (curtailments), often 10% of the advance after 30 or 45 days. Missing a curtailment triggers penalties and can freeze the credit line. This module tracks every vehicle's curtailment schedule, sends advance alerts, and optimizes the sequence of payoffs to minimize interest expense across the portfolio. When a dealer has limited cash to make principal payments, the system recommends which vehicles to pay down first based on interest rate, remaining term, and sell probability
Unit Economics
| Metric | Value |
|---|---|
| Monthly subscription (Standard: cost tracking + alerts) | $299/location |
| Monthly subscription (Premium: benchmarking + acquisition optimizer) | $699/location |
| Blended ARPU | $459/month |
| Data infrastructure cost per subscriber/month | $22 |
| DMS integration maintenance per subscriber/month | $15 |
| Customer acquisition cost | $2,400 |
| Expected LTV (28-month avg retention, 90% gross margin) | $11,566 |
| LTV:CAC ratio | 4.8:1 |
| Gross margin | 92% |
| Startup cost (18-month runway) | $2.4M |
| Break-even | 18 months |
Methodology note: The 28-month retention assumption reflects the nature of the product: once a dealer integrates floor plan cost tracking into their daily workflow (checking the dashboard each morning like they check auction listings), switching costs are high because the historical carrying cost data becomes the dealer's institutional memory of what vehicles cost to hold. CAC of $2,400 reflects B2B SaaS sales to a fragmented buyer base where NIADA conventions, state dealer association events, and 20 Group referrals are the primary distribution channels, supplemented by targeted digital marketing on AutoRemarketing, DealerElite, and the NIADA Dashboard newsletter. Gross margin of 92% reflects a software-plus-data model where the primary variable cost is DMS API access and data hosting. LTV calculation: $459 × 28 months × 90% gross margin = $11,566. Payback period: 5.2 months.
Go-to-Market
Phase 1 (months 1-8): Build integrations with the three most common independent dealer management systems: Frazer (market leader for small independents, 10,000+ dealers), DealerCenter, and DealerSocket. Launch a free carrying cost calculator (web-based, no integration required; the dealer enters vehicle, purchase price, floor plan rate, and estimated days to sell) to build an email list and establish credibility. Recruit 200 dealers across Texas, Florida, and the Southeast (the three densest independent dealer markets) to pilot the Standard tier in exchange for contributing anonymized floor plan terms to the benchmarking pool. Distribution: partner with NIADA state affiliates, attend the NIADA Convention & Expo and NAAA annual conference, and run targeted campaigns through AutoRemarketing and Used Car Dealer Magazine.
Phase 2 (months 9-16): Launch the rate benchmarking engine once the data pool reaches critical mass (150+ contributing dealers across at least 5 geographic regions). Introduce the Premium tier. Expand DMS integrations to include Wayne Reaves, Auto/Mate, and PBS Systems. Begin building the acquisition optimizer using historical auction data from OPENLANE's BacklotCars, ACV Auctions, and Manheim APIs to model days-to-sell predictions by make/model/year/mileage/geography. Target NIADA 20 Groups as a distribution channel: these peer advisory groups of 15 to 20 non-competing dealers are the ideal unit of adoption because if one member demonstrates floor plan savings, the rest follow.
Phase 3 (months 17-24): Launch the acquisition optimizer and curtailment payoff optimizer. Open an API for floor plan lenders who want to offer cost intelligence as a value-added service to their dealer clients (white-label model). Approach regional lender networks and credit unions that compete with NextGear and AFC on service rather than scale. These lenders would benefit from offering rate-transparency tools because their rates are often more competitive than the Big 2 but dealers don't know it. Enterprise tier at $1,499/month for multi-location independents (5+ lots) with portfolio-level analytics.
Competitive Landscape
| Company | What It Does | Floor Plan Cost Intelligence? | Pricing |
|---|---|---|---|
| vAuto (Cox) | Inventory pricing and market analytics based on VIN-level supply/demand | No: optimizes retail pricing, not carrying cost. Also owned by Cox, same parent as NextGear (structural conflict) | $750-1,500/mo |
| DealerSocket | Full DMS: CRM, inventory management, desking, F&I | No: tracks inventory counts, not per-vehicle carrying cost or rate benchmarks | $500-2,000/mo |
| Frazer DMS | Budget DMS for small independents (inventory, forms, compliance) | No: generates floor plan checks for auditors but provides no cost analytics | $99-199/mo |
| Lotlinx | AI-powered VIN-level advertising to reduce days-to-sell | Indirectly: faster turns reduce carrying cost, but doesn't track or optimize floor plan expense itself | Per-VIN pricing |
| NextGear Capital Portal | Lender's self-service portal: view balances, make payments, request advances | Shows your balance, not whether your rate is competitive. That's the lender's portal, not your advisor | Free (you're the product) |
| This startup | Floor plan cost intelligence: per-vehicle carrying cost, rate benchmarking, acquisition optimization | Core product: the dealer's side of the information asymmetry | $299-699/mo |
The structural gap is this: every existing tool in the independent dealer ecosystem either manages inventory (DMS), prices inventory for retail (vAuto, MaxDigital), or advertises inventory (Lotlinx, CarGurus). None of them answer the question that determines whether the dealer makes money: "What is this vehicle actually costing me to hold, and is that cost justified by its projected sale price and timeline?" The floor plan lenders' own portals show the dealer what they owe, not what they should be paying. That distinction, between a billing statement and a financial advisor, is the entire product opportunity. The hotel industry has IDeaS and Duetto for revenue management. Airlines have PROS and Sabre. Independent auto dealers have a whiteboard with days-on-lot tallied in marker, if they track it at all.
Why Now
Three forces make this moment distinctive. First, floor plan costs have roughly doubled in two years without the dealers getting any new tools to manage them. The Federal Reserve raised the federal funds rate from near-zero in early 2022 to 5.25-5.50% by mid-2023, where it held through late 2024. Floor plan rates, which are typically prime plus 2% to 6%, went from approximately 5-9% in 2021 to 10.5-14.5% at peak. A dealer carrying $500,000 in average floor plan debt saw their annual interest expense jump from roughly $25,000-$45,000 to $52,500-$72,500, an increase of $20,000 to $30,000 per year that came straight out of net profit. When money was cheap, sloppy inventory management was tolerable. At current rates, it's existential. BCG found that 38% of dealers reported floor plan costs severely impacting their business, a number that would have been in the single digits three years ago.
Second, the floor plan lending market is consolidating toward two dominant players whose market power depends on information opacity. NextGear Capital (Cox Automotive) and AFC (OPENLANE) together serve the vast majority of independent dealer floor plan volume. Cox Automotive also owns vAuto, the leading inventory management platform, and Manheim, the largest wholesale auction. This vertical integration means the same company that prices the dealer's wholesale purchase also finances that purchase, creating a structural incentive to keep the dealer buying and holding inventory even when the carrying cost math doesn't work. A SaaS tool that makes that math visible to the dealer represents a genuine disruption to the lenders' pricing power, which is precisely why the lenders will never build it themselves.
Third, DMS data is increasingly accessible through APIs. Frazer, DealerCenter, and DealerSocket have all expanded their integration capabilities in the last three years, driven by the broader auto retail API ecosystem that serves lenders, compliance vendors, and advertising platforms. The floor plan data that a cost intelligence product needs (advance amounts, rates, curtailment dates, vehicle-level payoff history) is already digitized in the DMS. What's missing is an analytical layer that transforms that transactional data into decision intelligence. The plumbing exists; the brain doesn't.
Original Contribution: The Floor Plan Opacity Tax
A calculation nobody has published: AFC reported a 22.1% return on tangible equity in 2024, up from 20.9% in 2023, on $1.55 billion in gross outstanding obligations. That return rate is extraordinary for a secured lending business where the collateral (vehicles) is liquid and easily recoverable. By comparison, the average commercial bank earned 10 to 12% return on tangible equity in 2024. The gap, roughly 10 percentage points, represents the premium that floor plan lenders extract from a borrower base that cannot comparison-shop.
Here's the math. AFC generated $232 in revenue per loan transaction in 2024 across 1,642,000 total transactions (comprising originations and curtailments). If we isolate the 1,012,000 new originations and assume an average advance of $15,300 (derived from the $1.55 billion outstanding divided by estimated 101,000 concurrent active loans, adjusted for turnover), the revenue per dollar advanced is approximately 1.5% per origination cycle. On an annualized basis, with an average loan duration of 45 to 60 days (typical for an independent dealer), that translates to an effective annual yield of 9 to 12% on the portfolio — well above the lenders' own cost of funds, which for investment-grade securitized debt is currently 5 to 6%.
The spread between the lenders' cost of funds (5-6%) and the effective yield on dealer floor plans (9-12%) is 3 to 7 percentage points. Applied to the estimated $10 billion in total independent dealer floor plan outstanding across all lenders, this spread represents $300 million to $700 million annually in excess interest that dealers pay above what a transparent, competitive market would produce. We call this the "floor plan opacity tax." It persists because dealers cannot benchmark their rates against the market, cannot model the true cost of holding each vehicle, and cannot time their curtailments and payoffs to minimize interest expense. Each of those three failures is a product feature waiting to be built.
To anchor that number in human terms: the average independent dealer carries roughly $350,000 in floor plan debt. At the midpoint of the opacity tax range (5 percentage points of excess spread on a portion of the rate, applied conservatively), a typical dealer overpays $3,000 to $8,000 per year relative to what they would pay if they could comparison-shop their floor plan the way they comparison-shop auto parts. A $299/month SaaS subscription that saves $5,000/year in floor plan cost pays for itself in 8.6 months.
Limitations
This analysis has several weaknesses that require honest disclosure. First, the "22.1% return on tangible equity" for AFC reflects the entire finance segment of OPENLANE, which may include ancillary products beyond pure floor plan lending (title services, dealer guarantees, insurance products). The actual return attributable solely to floor plan interest may be lower, which would compress the estimated opacity tax. We use the blended figure because OPENLANE does not break out floor plan interest income from other finance revenue at a granular level in public filings.
Second, the comparison to commercial bank returns (10-12%) is imperfect. Floor plan lending is operationally more expensive than typical commercial lending: lenders must conduct physical lot inspections (curtailment checks), manage high-frequency origination and payoff cycles (average loan duration of 45-60 days versus months or years for commercial loans), and absorb credit losses from a higher-risk borrower base. Some portion of the return premium compensates for these genuinely higher costs, not information asymmetry. The 2.2% provision for credit losses that AFC reported in 2024 confirms meaningful default risk. We estimate that operational costs and credit risk account for 1 to 3 percentage points of the return premium, leaving 2 to 4 points attributable to pricing power. Still substantial, but less dramatic than the headline 10-point gap suggests.
Third, the data chicken-and-egg problem for the rate benchmarking module is acute. Dealers may be reluctant to share their floor plan terms, even anonymized, because they fear their lender will find out and retaliate. Floor plan relationships are deeply personal. The dealer's NextGear or AFC rep often has discretion over credit line increases, fee waivers, and curtailment extensions. Antagonizing that relationship by contributing to a rate transparency platform carries real risk for the individual dealer, even if collective transparency would benefit the dealer population. This is the classic collective action problem, and it may require the startup to seed the benchmarking data through alternative sources (regulatory filings, state licensing data, or partnerships with dealer accounting firms) rather than relying solely on dealer self-reporting.
Strongest Counterargument
The most compelling case against this startup is that the floor plan lenders would view it as an existential threat and use their market power to kill it. NextGear Capital and AFC together serve the overwhelming majority of independent dealer floor plan volume. If either lender decided that a rate benchmarking tool was hurting their pricing power, they have several levers to discourage dealer adoption. They could introduce contractual provisions prohibiting dealers from sharing floor plan terms with third parties (similar to the gag clauses that health insurers have used to prevent price transparency). They could offer marginally better rates to dealers who don't use the tool, creating a soft exclusion. Or they could simply build a superficially similar "cost tracking" feature into their own dealer portals — one that shows carrying cost data without the competitive benchmarking that makes the product dangerous to the lender.
This is not hypothetical. The auto industry has a long history of vertical integration being used to control information flows. Cox Automotive owns Manheim (the largest wholesale auction), NextGear Capital (the largest independent dealer floor plan lender), vAuto (the leading inventory pricing tool), and AutoTrader/KBB (the largest consumer-facing marketplace). When Cox acquired vAuto in 2014, it gained the ability to see every independent dealer's inventory pricing strategy while simultaneously financing that inventory through NextGear. A startup that disrupts the financing leg of that value chain would face opposition from the most powerful ecosystem player in the industry.
The counterargument to the counterargument: the same vertical integration that gives Cox leverage also creates antitrust vulnerability. The DOJ has shown increasing interest in interlocking platform economics (the Google ad tech case, the RealPage algorithmic pricing case). A floor plan lender that actively suppresses rate transparency tools would be creating a paper trail for a future antitrust action. More practically, AFC (OPENLANE) is a publicly traded, independent competitor to NextGear — the duopoly structure means that whichever lender has better rates would benefit from transparency, creating a wedge that a startup can exploit. The lender with the lower rates wants the comparison published; the lender with the higher rates doesn't. A SaaS tool that publishes the comparison doesn't need both lenders to cooperate. It just needs one to not object.
The Bottom Line
Independent auto dealers paid an estimated $1.5 to $2.5 billion in floor plan interest and fees in 2024, financing 9.8 million vehicle sales on borrowed money they couldn't comparison-shop at rates they couldn't benchmark against the market. The lenders who collected that revenue earned returns on equity roughly double the banking industry average, a premium sustained by information asymmetry rather than operational superiority. Every adjacent industry (hotels, airlines, apartments, self-storage) has developed rate intelligence and yield management tools that give operators the same analytical capability as their largest competitors. Independent auto dealers have a whiteboard and a gut feeling. The tools to fix this already exist in concept: the data is in the DMS, the math is straightforward, and the distribution channels (NIADA, state associations, 20 Groups) are well-established. What's missing is someone who builds the product from the dealer's side of the table rather than the lender's.
What You Can Do
If you run an independent dealership with floor plan financing: pull your last 12 months of floor plan statements and calculate your actual effective annual rate (total interest and fees paid divided by average outstanding balance). Then call two competing floor plan lenders and ask for a rate quote. The spread between what you're paying and what you could pay is money you're leaving on the table every month. If you don't know your per-vehicle carrying cost beyond "it's about $X a day," you're making acquisition decisions without the most important input. Pull your last 50 sales, calculate the actual floor plan interest paid on each unit (advance amount × daily rate × days held), and rank them. The bottom 10, the vehicles that cost the most to hold relative to their gross profit, are the ones you should stop buying. If you're a DMS company building APIs: the dealer's floor plan data is sitting in your system. An analytics layer that transforms it into cost intelligence is a natural product extension, and it would be the single most defensible differentiator you could add to your platform. The DMS that helps the dealer make money, not just manage paperwork, wins the next decade.
