Fixed-rate equipment financing locks in the interest rate for the full term; variable-rate adjusts periodically based on a benchmark (prime rate, SOFR, etc.). Most equipment financing is fixed; variable shows up in some specialty products.
Side-by-side
| Fixed rate | Variable rate | |
|---|---|---|
| Rate over term | Same every month | Adjusts (typically monthly or quarterly) |
| Payment predictability | Same payment every month | Changes with rate adjustments |
| Borrower risk | None (rate locked) | Pays more if rates rise |
| Lender risk | Lender bears rate-rise risk | Borrower bears it |
| Initial rate | Slightly higher (lender prices in risk) | Slightly lower (lower initial advantage) |
| Total cost predictability | Known at signing | Depends on rate path |
What’s standard in equipment financing
Fixed rate dominates. Reasons:
- Borrower cash-flow predictability
- Equipment financing terms (24-84 months) are short enough that lenders price fixed rates competitively
- The market expects fixed rates; lenders that offer variable struggle to compete
Where variable rates appear
- SBA 7(a) loans: often variable (prime + spread); can convert to fixed
- Some specialty equipment loans over 10 years: rate risk for the lender is meaningful at that duration
- Lines of credit: revolving credit is universally variable
- Aircraft financing: some long-term aircraft loans use variable rate
When variable rate makes sense
- You believe rates will fall during the loan term (variable benefits you)
- You want the lower initial rate even at the cost of variability
- You expect to prepay the loan within 2-3 years (limiting rate-rise exposure)
- The loan has a rate cap (maximum rate floor)
When fixed rate is the safe choice
- You want predictable monthly payments for budgeting
- You expect to hold the loan to maturity
- Rate environment is rising or expected to rise
- You don’t want exposure to interest-rate volatility
The math example
$100K loan, 60-month term.
- Fixed at 10% APR: monthly $2,125, total $127,500
- Variable starting at 9% (prime + 2%), assuming rates stay flat: monthly $2,076, total $124,560
- Variable if rates rise 2% in year 1: payments increase mid-term, total ~$130K
- Variable if rates drop 2% in year 1: payments decrease, total ~$118K
The starting rate advantage is modest. The total-cost difference depends on rate path, which you can’t predict.
SBA 7(a) variable specifically
SBA 7(a) loans default to variable rate. They’re priced at prime + 2.25-4.75% (depending on loan size and term). Borrowers can request fixed rate but it may add 0.5-1% to the spread.
For long-term SBA loans (10-25 years), variable carries meaningful interest-rate risk. Many borrowers convert to fixed via the SBA’s structures or refinance into a fixed-rate loan when rates are favorable.
How to evaluate
- Get both fixed and variable quotes if both are offered
- Calculate worst-case (rate cap scenario) for variable
- Compare worst-case variable total cost to fixed total cost
- If you can’t absorb the worst case, take fixed
- If the worst-case is comfortable, variable’s starting savings may be worth the risk
