SBA Express loan calculators

Two calculators for SBA Express borrowers. One prices the loan; the other tests whether a line of credit can be structured the way you want it. Nothing is saved and nothing is sent anywhere, and the math runs in your browser.

Start here if the question is what it costs every month

The SBA Express payment calculator answers the question most borrowers arrive with. Enter an amount, a term, and a rate, and it returns the level payment, the total interest, and the full amortization schedule.

It also returns three things a generic payment calculator will not. It shows the highest rate SBA allows at that loan size, so you can see whether the rate you were quoted sits near the ceiling or nowhere near it. It shows the 50% guaranteed portion, which is the figure the upfront guaranty fee is actually charged on, and the reason that fee is smaller than most people expect. And it applies the FY2026 fee schedule, including the veteran and small manufacturer waivers.

Reach for it when you have a quote in hand and want to check it against the program ceiling, or when you are choosing between a 10-year working capital maturity and a longer one on real estate.

Use the other one if the money is a line, not a term loan

The SBA Express line of credit calculator answers a different question, and it is the question that comes first: is the structure you have in mind even permitted?

An Express line is a draw period followed by a term-out, and three rules interact in a way that quietly rules out combinations which sound perfectly reasonable. Total maturity cannot exceed 10 years counting the term-out. No advances are allowed after the first 60 months. A revolving line running longer than 12 months has to carry a term-out at least as long as its draw period. Set a maturity and a draw period, and the calculator either sizes the two payments or names the rule the combination breaks.

It also shows the step-up: the draw-period payment modeled as interest only, the fully amortizing term-out payment, and the gap between them. That gap is what catches borrowers out in the first month after the draw period closes.

Which one do you need?

If you are buying equipment, paying for leasehold improvements, or funding a one-time working capital need, it is a term loan, and the payment calculator is the right tool. If you need to draw and repay repeatedly against receivables or inventory, it is a line, and the structure question has to be settled before the payment question means anything.

Either way the same program limits apply. SBA Express tops out at $500,000, SBA guarantees 50% of it rather than the 75% to 85% a standard 7(a) loan carries, and balloon payments are not permitted, so whatever you borrow has to fully amortize by its maturity date.

What these calculators do not decide

Neither one is a quote. SBA caps the spread a lender may charge over a base rate; it does not set your rate, and it has no view on whether you get the loan at all. Your rate, your fees, your term, and your collateral requirements are the lender's, inside SBA's rules, and two lenders looking at the same business routinely land in different places.

When you want figures from actual lenders rather than a model, tell us what the business needs and we route the inquiry to SBA lending partners. If you are still deciding between programs, the SBA loan comparison puts 7(a), 504, and Express side by side.
