What Is a Good Debt Service Coverage Ratio (DSCR)? The 1.25 Bar, the Formula & How to Improve It (2026)

Lenders rarely ask for your debt service coverage ratio by name on a short application — but they calculate something very close to it on nearly every file. DSCR is the single number that answers the question every underwriter is really asking: after paying to run the business, is there enough cash left to pay the debt?

Key takeaway (TL;DR) DSCR compares a business's operating income to its total debt payments. Divide net operating income by total annual debt service: a result of 1.25 means the business earns $1.25 for every $1.00 of debt payments. Most term lenders and SBA programs look for 1.25 or higher; 1.00 is breakeven; below 1.00 the business does not cover its debt from operations. Revenue-based funders often skip the formal ratio, but they run the same math in disguise — the dead-week test is DSCR with a weekly lens.

The formula, with a worked example

DSCR = Net Operating Income ÷ Total Debt Service

Net operating income (NOI) is revenue minus operating expenses — rent, payroll, supplies, insurance, marketing — before debt payments. Total debt service is every loan payment due in the year: principal plus interest on term loans, lines of credit, equipment loans, and any advances being repaid, plus capital lease payments where the lender counts them.

A worked example: a wholesale distributor takes in $1,400,000 in revenue and spends $1,220,000 running the business, leaving NOI of $180,000. Its debt payments for the year total $120,000 across a term loan and an equipment loan. DSCR = $180,000 ÷ $120,000 = 1.50. The business earns one and a half times what its debt costs — a comfortable file for most lenders.

The contractor at 0.92 is the file that stalls: the business earns $110,000 against $120,000 of payments, so something — reserves, owner cash, or a new advance — has to fill a $10,000 gap before the lender is comfortable.

What counts as operating income — and what does not

Underwriters do not take the tax return's bottom line at face value. They adjust it, and knowing the adjustments is half the game:

• Add back depreciation and amortization. These are paper expenses, not cash out the door, so most lenders add them back to income.
• Add back one-time expenses. A lawsuit settlement, a flood repair, or a single bad-debt write-off that will not recur can often be added back — with documentation.
• Adjust owner compensation. If the owner pays themselves far above or below market, lenders may normalize it. An owner taking $200,000 from a business that would pay a manager $90,000 will see the difference questioned.
• Do not count one great month. Lenders annualize from trailing-twelve-month figures, not the best quarter. A seasonal spike does not fix a weak year.
• Do not count revenue as income. The most common borrower mistake is dividing revenue by debt payments. A $2 million business with $1.9 million of expenses has $100,000 of income, not $2 million — and its DSCR is computed on the $100,000.

What counts as debt service — including advances

Every scheduled payment counts: term loan principal and interest, line-of-credit payments, equipment financing, SBA loan payments, and commercial mortgages. Two items borrowers forget:

• Merchant cash advances. An MCA has no monthly payment, but it has a daily or weekly debit. Annualize it — a $400 daily debit over roughly 250 business days is $100,000 a year of debt service — and include it. Lenders will find it in the bank statements anyway; disclosing it first reads as honesty, not weakness.
• The new loan itself. DSCR is usually computed after the proposed financing: the lender adds the new payment to existing debt service and checks the ratio still holds. A business at 1.40 today can fall below 1.25 once the new loan's payments are added — which is exactly why some applications that look strong still decline.

What is a good DSCR? The bar by product

The 1.25 figure is not a law — it is the convention most SBA lenders and banks use, and many online term lenders accept 1.20. MCA and revenue-based funders often do not publish a DSCR requirement at all, because they underwrite on deposits and daily balances instead. But the underlying question is identical: can this business carry this payment? A merchant taking a daily-debit advance should run the same test themselves — the dead-week test in our MCA guides is DSCR applied to the worst week instead of the year.

How to improve your DSCR before you apply

Five levers, in order of how quickly they move the number:

• Refinance or extend existing debt. Stretching a 3-year loan to 5 years lowers the annual payment and raises DSCR immediately, without changing income at all. Consolidation works the same way when it replaces several short, expensive payments with one longer one.
• Pay down the smallest balance. Eliminating one payment entirely removes it from debt service. Clearing a $1,500-a-month equipment loan lifts annual debt service by $18,000 — often enough to cross from 1.20 to 1.25.
• Document your add-backs. Gather the paperwork for every one-time expense and every depreciation schedule before applying. An undocumented add-back is an add-back the underwriter will not grant.
• Time the application after a strong period. Because lenders use trailing-twelve-month figures, applying right after a strong quarter — rather than right after a weak one — can change the ratio materially, especially for seasonal businesses.
• Right-size the request. Asking for less lowers the new payment and keeps post-loan DSCR above the bar. A business at 1.30 that asks for a loan pushing it to 1.18 may get declined; the same business asking for 20% less may get approved.

One confusion to clear up: the ratio vs. the rental loan

You may also see "DSCR loans" advertised to real estate investors. That is a different product that happens to share the initials: a DSCR rental loan lets an investor qualify based on a property's rental income rather than personal income. The ratio explained in this guide is the business-lending metric — operating income divided by debt service — used to judge whether a company can carry a loan. Same letters, different question.

Five mistakes that sink an otherwise good file

• Quoting revenue instead of income. Lenders divide by debt service against operating income, never gross revenue.
• Forgetting an existing advance. Daily debits are debt service. Undisclosed positions surface in underwriting and damage credibility.
• Using one great month. Trailing-twelve-month math smooths the spike away; present the full year honestly.
• Ignoring the new payment. Compute DSCR with the proposed loan included, not just today's debts.
• Applying at the seasonal low. For seasonal businesses, the quarter you apply in can move the ratio by more than any single fix.

Run the number before a lender does. If it lands at 1.25 or above with the new payment included, the file starts from strength. If it lands below, the five levers above — especially refinancing and right-sizing — are the cheapest fixes available, and they cost nothing but a week of preparation.
