How a Fed Rate Hike Changes Your Business Loan Payment
Last reviewed November 6, 2026
If your loan floats with prime, a quarter-point increase raises annual interest cost by balance × 0.25%. On $500,000.00 that is $1,250.00 a year. Fixed-rate loans do not change until refinanced or their fixed term resets.
Extra annual interest = balance × rate change
Extra monthly interest = extra annual interest / 12
Illustrative example
Examples use made-up numbers. Education only, not tax, legal or investment advice.
- Fictional owner’s variable balance: $500,000.00.
- Rate rise: 0.25 percentage point = 0.25%.
- Extra annual interest = $500,000.00 × 0.25% = $1,250.00.
- Extra monthly interest = $1,250.00 / 12 = $104.17, about $104.00.
- Stress case: three 0.25-point increases = 0.75 point; $500,000.00 × 0.75% = $3,750.00 per year.
This is an interest-only comparison on a constant balance, not a recalculated amortizing payment. Actual payments depend on the loan agreement, balance and reset timing.
Which debt moves?
| Loan type | Does it move with the Fed? | What to check |
|---|---|---|
| Variable line of credit | Often indirectly, through prime or another index | Index, margin, reset date, floor and balance |
| Variable term loan | If its benchmark changes | Reset schedule and whether the payment or term changes |
| Fixed term loan | Not during its fixed term | Refinance date, balloon and prepayment penalty |
| Equipment lease | Not automatically if payments are fixed | Fixed versus indexed payments and end-of-term terms |
| Merchant cash advance | Not automatically; contract terms control | Factor, fees, repayment share and total repayment |
Test the thin quarter
List every variable-rate balance and its reset date. Put the extra interest into the weeks when it is due, then check your lowest projected cash balance.
Do not assume a Fed move passes through immediately or one-for-one to every loan.
Key takeaways
Questions owners ask
Do Fed hikes change my fixed-rate loan?
No, not during the fixed term. Your rate may change when you refinance or the term resets.
What is prime?
Prime is a bank benchmark rate that generally tracks the Fed target. Many variable business loans are prime plus a margin; check your contract’s benchmark.
Should I refinance?
It depends on terms, fees and prepayment penalties. Talk to your CPA and lender before deciding.
