Business Loan Qualifier

1. Enter annual business revenue (gross sales before expenses) for the most recent full year or trailing twelve months.
2. Enter monthly net profit after ordinary business expenses — the cash flow lenders care about for debt service.
3. Add years in business. Many conventional and SBA programs prefer at least two years of operating history.
4. Enter your personal credit score (FICO-style). Business credit may also matter, but this model uses personal score as the primary input.
5. Enter the loan amount you want. Requesting less than the estimated maximum often improves the modeled approval chance.

The tool builds a simple underwriting sketch. Maximum loan is capped as the lesser of roughly half of annual revenue and about 3.5 times annualized net profit. Debt service coverage (DSCR) compares monthly profit to an estimated payment on the amount you need at an illustrative rate and term. An approval-chance score adds points for stronger credit bands, longer operating history, healthier DSCR, and higher revenue — then caps the result. The estimated rate steps down as credit improves. None of these outputs is a lender decision.

Max loan ≈ min(annual revenue × 0.5, annual net profit × 3.5)
DSCR ≈ monthly net profit ÷ estimated monthly payment on requested amount
Approval chance = capped sum of credit + years + DSCR + revenue factors

Imagine a business with $200,000 annual revenue, $8,000 monthly net profit ($96,000/year), three years in operation, a 680 credit score, and a $50,000 loan request. Max loan ≈ min($100,000, $336,000) = $100,000, so the request sits under the cap. Annualized profit supports a payment on $50,000 at the model’s illustrative rate with DSCR above common 1.25-style checkpoints, and the score adds points for 680 credit, 3+ years, solid DSCR, and revenue over $100k — producing a relatively strong approval-chance estimate and a mid-single to high-single-digit illustrative rate band in this model. If the same owner asked for $150,000, the request would exceed the $100,000 max estimate and the verdict would push toward lowering the ask. Treat every percentage as a planning signal, not a prediction that a bank will approve you.

Max loan estimate

A rough ceiling based on revenue and profit multiples used in this educational model. Real lenders may use different multiples, collateral, or global cash-flow tests.

Approval chance

A scored estimate from the inputs above — not a probability from a credit bureau or lender. It can never guarantee approval or denial.

Est. interest rate

An illustrative rate band tied mainly to credit score tiers in this tool. Live offers depend on product type, collateral, guarantees, and market rates.

DSCR ratio

Debt service coverage: how many times monthly profit covers an estimated loan payment. Higher is generally healthier; many credit policies look for ratios above about 1.25, but requirements vary.

Eligibility factors / Verdict

A checklist-style view of whether credit, history, revenue, and DSCR clear simple thresholds in this model, plus plain-language next-step guidance.

• Reading “approval chance” as a real lender probability or pre-qualification.
• Using revenue without confirming profit and tax returns can support the payment.
• Applying with thin operating history when the product requires two-plus years.
• Ignoring personal credit issues that still drive many small-business underwriting decisions.
• Sizing the ask to the max estimate instead of the amount you can repay comfortably.

Max loan uses simple multiples of revenue and profit. Payment and DSCR assume an illustrative rate and a 60-month amortization on the requested amount for modeling only. Approval chance is a capped heuristic, not empirical default data. Rate tiers are illustrative by credit band and ignore collateral, guarantees, industry risk, and current market benchmarks. Results are estimates only and are not a loan offer, pre-approval, or credit decision.
