The word to understand first in a DSCR loan is debt service. The SBA defines debt service as “the future required principal and interest payments on all business debt, inclusive of new SBA loan proceeds,” and its underwriting rules use that figure when they judge a loan. For the full DSCR formula and how it applies to real estate loans, read our DSCR loan guide.
What debt service means in practice
Debt service is the total of what you must pay on your debt over time. The SBA’s 7(a) loan page says most 7(a) term loans are repaid with monthly payments of principal and interest from the cash flow of the business. Payments stay the same on a fixed-rate loan because the interest rate is constant. On a variable-rate loan, the lender may require a different payment when the rate changes (SBA 7(a) loans page, captured October 28, 2026).
The SBA also says a 7(a) borrower must be creditworthy and show a reasonable ability to repay the loan. That is the reason lenders care about the payment figure. For more on the SBA route, see our SBA 7(a) loan guide.
How rates change the payment
The rate you are offered sets the size of each payment. The SBA’s 7(a) page lists the maximum allowed rates by loan size, measured against the base rate:
| Loan amount | Maximum interest rate (sba.gov, captured October 28, 2026) |
|---|---|
| $50,000 or less | Cannot exceed base rate +6.5% |
| $50,001 to $250,000 | Cannot exceed base rate +6.0% |
| $250,001 to $350,000 | Cannot exceed base rate +4.5% |
| $350,001 and greater | Cannot exceed base rate +3.0% |
The base rate is often prime. The Federal Reserve’s H.15 release dated October 27, 2026 publishes the bank prime loan rate and notes that prime is one of several base rates banks use to price short-term business loans (Federal Reserve H.15 release). SBA’s procedural notice on lender loan programs says a variable-rate 7(a) loan may use the prime rate or the SBA Optional Peg rate as its base, under 13 CFR 120.214 (SBA procedural notice 5000-875051).
Is a DSCR loan the same as an SBA loan?
No. The SBA 7(a) loan page does not mention DSCR loans, so the SBA rules above describe SBA-backed business loans. Keep the two apart when you compare offers. The DSCR specifics are in our DSCR loan guide.
What to ask your lender before you apply
Ask for three things in writing before you apply:
- The debt service formula the lender uses, and which debt payments and which income figures go into it.
- The base rate and spread on any variable-rate offer, and how often the rate can change.
- The monthly payment on the loan amount you are asking for, so you can compare it with your own numbers.
If you want an SBA-backed loan, the SBA’s Lender Match tool connects you with participating SBA lenders (SBA 7(a) loans page).
Before you apply
- Get the debt service formula in writing from each lender.
- Check whether the rate is fixed or variable, and what base rate it uses.
- Compare the monthly payment, not only the rate, across offers.
This is general information, not personal financial advice. Nothing here promises approval, a rate, an amount or a timeline. Rates and figures are as of the October 27 and October 28, 2026 captures named above, and lenders set their own terms.
