Debt Service Coverage Ratio: What Lenders Check First

When a commercial lender assesses a business loan, DSCR is usually the first number calculated and the one most likely to produce a decline. It is worth knowing yours before you apply.

#The calculation

DSCR = Net operating income / Total debt service

Net operating income is typically EBITDA — earnings before interest, tax, depreciation and amortisation — often with adjustments for owner compensation above market rate and genuinely non-recurring items.

Total debt service is all principal and interest payments across every facility, including the loan you are applying for.

A business with $216,000 of annual EBITDA and $160,000 of total annual debt service has a DSCR of 1.35.

#What the thresholds mean

Below 1.0 — the business does not generate enough to cover its debt payments. Declined, in nearly all cases.

1.0 to 1.15 — technically covered, no margin. Most lenders decline; some approve with additional collateral or a personal guarantee.

1.20 to 1.25 — the common minimum. SBA lenders frequently sit at 1.15 to 1.25; conventional bank lending usually wants 1.25.

1.35 to 1.50 — comfortable. Better pricing available.

Above 1.50 — strong. Reasonable negotiating position on rate and terms.

The business loan calculator computes DSCR from your monthly EBITDA and the loan payment, and flags where you fall against these bands.

#Why lenders weight it so heavily

Credit score tells a lender about past behaviour. Collateral tells them about recovery if things go wrong. DSCR tells them whether the loan can be repaid from operations, which is the outcome everyone actually wants.

It also has a practical property: it scales. A lender can compare a $50,000 equipment loan and a $2M property acquisition on the same basis.

#What counts in the numerator

This is where applications are won and lost, and where a good accountant earns their fee.

Add-backs lenders typically accept:

• Owner compensation above a market rate for the role
• Genuinely one-off legal or professional costs
• Non-cash charges such as depreciation and amortisation
• Discretionary expenses that would not survive a change of ownership

Add-backs lenders typically reject:

• "We could cut marketing if we needed to"
• Optimistic revenue not yet realised
• Personal expenses run through the business that will continue

Present add-backs clearly, with documentation, in the application rather than in response to a query. An unexplained adjustment reads as an attempt to inflate the number.

#How to improve your DSCR

Extend the term. The fastest lever. Moving a $150,000 loan from 36 to 60 months cuts the monthly payment by roughly a third and raises DSCR proportionally. It costs more total interest, which is a real trade-off — model both in the calculator.

Borrow less. Consider whether the full amount is needed now or whether the purchase can be staged.

Clear existing facilities first. Paying off a small high-payment loan before applying can move DSCR more than a comparable increase in earnings, because it removes the payment from the denominator entirely.

Time the application. DSCR is usually calculated on trailing twelve-month figures. Applying immediately after your strongest quarter presents better than applying after your weakest.

Reduce owner compensation temporarily, with the add-back documented. This works but be honest that it is presentational rather than operational.

#Global DSCR

For small businesses where the owner personally guarantees the debt, many lenders compute a global DSCR combining business and personal income and obligations — including your mortgage, car loans and personal credit.

This catches applicants off guard. A business with a healthy 1.4 DSCR can fail a global test if the owner carries substantial personal debt. If you are applying for an SBA loan or anything requiring a personal guarantee, calculate both.

#The related ratios

Loan-to-value on secured lending — typically 65% to 80% depending on asset type.

Debt-to-EBITDA — total debt divided by annual EBITDA. Below 3× is comfortable, above 4× is stretched, above 5× is difficult.

Current ratio — current assets over current liabilities. Above 1.2 indicates adequate short-term liquidity.

A strong DSCR alongside weak liquidity still prompts questions, because covering payments on paper does not help if the cash arrives after the payment is due.

#The version that matters most

Ultimately DSCR is a stress test you should be running for yourself, not just for a lender. At 1.1×, a single lost customer, a slow quarter or an equipment failure puts you in default. At 1.4× you have room to absorb a bad quarter without a difficult conversation.

Borrow the amount that leaves you above 1.25× with the shortest term you can comfortably service — and model the scenario where revenue falls 15% before you sign.
