What Is DSCR and Why Lenders Care About It

If you’ve started researching business funding, you may have come across the term DSCR — Debt Service Coverage Ratio. It’s one of the more important numbers in underwriting, especially for larger or longer-term financing.

What DSCR actually measures

DSCR compares how much cash flow your business generates to how much debt you owe. Specifically, it’s calculated by dividing net operating income by total debt obligations. A DSCR above 1.0 generally means your business generates more income than it needs to cover its debt payments; below 1.0 means the opposite.

Why it matters more than a simple revenue number

Revenue alone doesn’t tell a lender much about whether you can comfortably make payments — a business with high revenue but thin margins and heavy existing debt might actually have less repayment capacity than a smaller business with healthy margins and little debt. DSCR gets closer to the real answer.

What a “good” DSCR looks like

This varies by lender and program, but many look for a DSCR comfortably above 1.0 — giving some cushion above simply breaking even on debt obligations. The exact threshold depends on the specific funding program and how much risk that lender is willing to take on.

Can you improve your DSCR?

Yes, over time — by growing operating income, paying down existing debt, or both. In the short term, being aware of your DSCR helps you understand what size and structure of funding is realistic for your business right now, rather than applying for more than makes sense.

You don’t need to calculate this alone

Your funding specialist can walk through what matters most for the specific programs you’re being matched to — DSCR is one piece of a larger picture your application builds.

Frequently asked questions

Is DSCR the same for every funding type? DSCR matters most for larger or longer-term financing, such as SBA loans and commercial real estate financing, where lenders want more assurance of repayment capacity over a longer commitment.
