DSCR: What SBA Lenders Actually Check

Debt service coverage ratio, or DSCR, compares cash available for debt service with the required principal and interest payments. A projected ratio above 1.0x means the model shows enough cash to pay scheduled debt; a ratio below 1.0x shows a shortfall. In practice, many SBA lenders look for projected coverage in the region of 1.15x to 1.25x rather than a bare 1.0x, because the buffer absorbs normal variance in revenue and costs. The exact threshold is set by the individual lender's credit policy.

A lender does not review the ratio in isolation. The first question is whether the cash-flow numerator is credible. Revenue should follow operating drivers, margins should reconcile to the business model and owner compensation, working capital, taxes and recurring capital expenditure should be treated consistently.

Historical performance matters for an existing business. Lenders may normalise owner expenses, one-off items and discretionary costs, but each adjustment needs evidence. A projection that improves sharply from history requires a clear operational explanation rather than a typed growth rate.

For a startup or acquisition, the assumptions carry more weight because there is less historical cash flow. The plan should connect customer volume, pricing, staffing, operating costs and ramp-up to the projected statements. The debt schedule must use the actual proposed amount, rate, term and repayment structure.

Timing matters. An annual ratio can hide a monthly shortfall during ramp-up or a seasonal low point. A monthly cash-flow model for the first year shows whether working capital and loan proceeds are sufficient before the business reaches stabilised coverage.

Lenders also examine downside headroom. What happens if revenue is lower, opening is delayed, margins compress or costs rise? The model should show the effect on cash and coverage without changing the debt terms. A downside case that still services debt is more persuasive than a base case engineered to clear a threshold narrowly.

SBA requirements and lender policies vary, so the lender remains the source for the applicable underwriting standard. A model-led SBA plan makes that review easier by showing where every cash-flow and debt-service figure comes from.
