The 20-second answer
DSCR = annual cash flow ÷ all annual debt payments. Most SBA lenders require at least 1.15×, and many underwrite to 1.25× — meaning the business must throw off $1.25 for every $1.00 of loan payments. Count the bank loan and any seller note that's actually being paid: if part of the price is seller-financed, those payments lower your real DSCR. A note on full standby (no payments for the first year or two) is left out until it kicks in.
What DSCR is and why lenders live by it
Debt Service Coverage Ratio measures whether a business produces enough cash to pay its loan. It's the first ratio an SBA underwriter calculates, because it answers the only question the bank truly cares about: after the business pays its bills, is there enough left to make the loan payment, with room to spare?
A deal doesn't get approved because the price is fair. It gets approved because the cash flow covers the debt.
How to calculate DSCR for a business acquisition
For a small business bought with an SBA loan, use:
- Cash flow available for debt service — usually Seller's Discretionary Earnings (SDE). If you plan to hire a manager instead of running it yourself, subtract that manager's market salary first, because the lender will.
- Annual debt service — twelve monthly payments on the proposed loan (principal + interest). Include any other business debt that will survive closing.
Then divide. The calculator above does this, subtracts your salary if you enter one, and shows the maximum debt service the business could support at your target ratio — which tells you how much you can safely borrow.
| DSCR | What it means | Lender view |
|---|---|---|
| Below 1.0× | Cash flow doesn't cover the payment | Declined |
| 1.0×–1.15× | Covers the payment with no cushion | Tight, often declined |
| 1.15×–1.25× | Small but real cushion | Acceptable to most SBA lenders |
| 1.25×–1.50× | Healthy cushion | Comfortable approval |
| Above 1.50× | Strong coverage | Strong, room to grow debt |
Thresholds reflect common SBA 7(a) lender underwriting standards (typical minimum 1.15×, conservative 1.25×). Individual lenders vary — confirm with yours.
Use DSCR in reverse to set your max price
Flip the formula: max annual debt service = cash flow ÷ target DSCR. Feed that payment into the max purchase price calculator and you'll know the biggest deal the business can actually carry — before you fall in love with a listing.
Five ways to fix a DSCR that's too low
- Lengthen the term. Stretching a loan from 10 to 25 years (when real estate is involved) cuts the payment and lifts DSCR immediately.
- Add a seller note on full standby. Payments deferred for the SBA-required period don't count against DSCR during standby.
- Negotiate the price down. Less debt, smaller payment, higher ratio.
- Bring more equity. A larger down payment shrinks the loan.
- Find real add-backs. Legitimate owner expenses added back raise SDE, and DSCR — but only if they're defensible in a Quality of Earnings review.
Frequently asked questions
Most require a minimum of 1.15×; many underwrite to 1.25×. A 1.25× DSCR means $1.25 of cash flow per $1.00 of annual payment, a 25% cushion.
If you'll run the business full-time, most SBA lenders let you count the owner's salary as available cash flow (you can live on the business's profit). If you'll stay at your job and hire a manager, subtract that manager's market salary — the lender will.
Safer, yes — more cushion for a slow year. But a very high DSCR can also mean you're under-leveraged and could afford a larger, better business for the same equity. Balance safety with using cheap SBA leverage well.
