The short answer: most SBA 7(a) acquisition loans carry a variable rate tied to prime, so when rates rise, your monthly payment rises, your DSCR falls, and the maximum price the same cash flow can support goes down. The business did not change; the cost of the money did. Understanding this chain lets you protect the deal with a lower price, a bigger seller note, or a longer term.
The chain: rate, payment, DSCR, price
Here is the whole idea in one line. A higher rate means a higher payment, a higher payment means a lower DSCR, and a lower DSCR means the lender will support a smaller loan on the same cash flow. Since the loan funds most of the price, a smaller loan means a lower price you can actually pay. The cash flow is fixed; the rate decides how much of it the debt eats.
A worked example
Take a business with $300,000 of verified cash flow and a lender minimum DSCR of 1.25x. That means the deal can support about $240,000 of annual debt service. How much loan that buys depends entirely on the rate. The numbers below are illustrative and rounded to show the direction, not a quote.
| Interest rate | Annual payment supported | Approx. loan supported |
|---|---|---|
| 9% | $240,000 | ~$1.52M |
| 10.5% | $240,000 | ~$1.42M |
| 12% | $240,000 | ~$1.33M |
Three points of rate quietly erased almost $200,000 of buying power on the exact same business. That is why two buyers can look at one deal a year apart and reach completely different conclusions about whether it pencils.
What to do when rates work against you
- Negotiate the price down. If money costs more, the deal is worth less. The seller's expectation should follow the market, not fight it.
- Add a seller note. A standby seller note reduces the senior debt and the payment that has to clear.
- Lengthen the term. A longer amortization lowers the annual payment, though you pay more interest over time.
- Demand cushion. Buy at a DSCR well above the minimum so a future rate bump does not put you underwater.

Rates do not change the business. They change how much of its cash flow the bank takes, and that is what sets your ceiling.
Frequently asked questions
Most SBA 7(a) acquisition loans carry a variable rate tied to the prime rate, so the payment moves as prime moves. Some lenders offer fixed-rate options; ask, because the rate structure directly affects how much price your cash flow can support.
A higher rate raises the loan payment, which lowers your DSCR. Since lenders size the loan to keep DSCR above their minimum, a higher rate means a smaller loan on the same cash flow, and therefore a lower price you can afford.
Negotiate a lower price, add a standby seller note to reduce senior debt, lengthen the amortization to lower the annual payment, and buy at a DSCR well above the lender minimum so a future rate increase does not sink the coverage.
