BHPH Capital Requirements Calculator — Dealer & Finance Managers

If the capital figure this calculator returns is within reach of your current funding options, your next step is to stress-test that number against a 15–20% default scenario before you commit. Keep in mind the actual amount you'll need shifts with your local market, deal mix, and how aggressively you plan to grow — this estimate is a floor, not a ceiling.

What changes your capital requirement

• Average loan amount. The single biggest lever. Dropping your average financed balance from $9,500 to $7,500 per deal cuts portfolio exposure by roughly 21% at the same unit volume.
• Down payment percentage. Higher down payments reduce the amount you carry per loan and lower default risk simultaneously — a compounding advantage for effective risk management in 2026.
• Monthly unit volume. More deals per month means your portfolio builds faster, which is good for cash flow but demands proportionally more working capital upfront.
• Reserve rate. BHPH portfolio default rates in 2026 typically run 15–25% depending on underwriting discipline. Your reserve rate should reflect your actual or expected loss experience — not the industry floor.
• Loan term. Longer terms keep monthly payments lower (improving customer qualification), but they slow capital recycling. Shorter terms free up cash faster but raise the monthly payment-to-income ratio for your borrowers.

How to use this calculator

• Enter your target portfolio size (number of active loans you want on the books at steady state) — not your monthly volume.
• Use your actual average deal, not your best deals. Pull the last 90 days of contracts if you have them; use comparable market comps if you're pre-launch.
• Set the reserve rate honestly. Sub-prime auto loan strategies that underestimate loss reserves run dry inside 18 months. If you're unsure, start at 18%.
• Read the output as deployed capital, meaning cash that must be available and committed — not just accessible on a credit line you haven't drawn.
• Re-run with a 20% default shock. If the stressed number still works, your capital plan is solid. Independent commercial lenders evaluating your BHPH portfolio will apply similar stress tests — the same scrutiny dealer financing faces versus bank lending applies when you seek outside capital for your program.

Bottom line

BHPH dealer financing is a balance-sheet business: every dollar you lend has to come from somewhere, and undercapitalization is the most common reason new programs fail inside two years. Run this calculator with your real deal economics, stress-test the reserve line, and make sure your funding structure can sustain the number before you write the first contract.
