Estimates only, not a loan offer. SBA microloans are capped at $50,000 with terms up to 7 years; the average SBA microloan is about $13,000. Loans come from nonprofit intermediary lenders, not from the SBA directly.

Enter an amount up to the program cap, a rate inside the program band and a term up to the program maximum — the calculator returns your monthly payment, total interest, total of payments and total cost including any origination fee, plus the amortization schedule. A note of honesty up front: microloans amortize like any other term loan — the same formula drives this page and the general business loan calculator. What differs is the envelope around the math: the size ceiling, who lends, and the rate band, and those program facts are what this page wraps around the numbers.

General information, not financial advice, and estimates only. Microloan terms are set by the intermediary lender, not by this tool; use the result to judge whether a quote is in the program’s normal range.

What to enter

Worked example (the default view)

A $25,000 microloan · 10% APR · 72 months:

Context for that amount: per SBA program figures, the average SBA microloan is about $13,000 — roughly half this example. At 10% over 72 months that average loan would run about $241 a month. Run your real amount: microloan payments stay modest precisely because the balances do, and the binding constraint for most borrowers is not the payment but whether the intermediary serves their area and industry.

The program facts that shape the inputs

Three facts from SBA.gov drive the fields above. The cap: SBA microloans top out at $50,000 — a hard program limit, with most loans far below it. The term: the maximum maturity is 7 years; intermediaries set shorter terms freely within it, so a 36- or 48-month quote is normal, not a red flag. The lender: you do not borrow from the SBA. The SBA funds nonprofit, community-based intermediary lenders, and the intermediary makes — and prices — your loan inside the program’s rules. Rates therefore vary by intermediary within the published 8–13% band, and technical-assistance requirements (business training or counselling) sometimes come attached to the loan, which is part of the program’s design, not a lender quirk.

What this page deliberately does not do

Eligibility, the application process, finding an intermediary and what to do if your business is pre-revenue all live in the SBA microloans guide — this calculator will not re-teach them, and the guide is the page to read before you apply. Two neighbouring questions also get their own tools: whether your cash flow supports a payment of this size at all is the affordability calculator’s job (it works from revenue and coverage rather than from an amount), and the lender-gate view of the same question — credit, time in business, documentation — is covered on how much business loan can I qualify for. This page’s one job is the arithmetic, inside the program’s real limits.

Comparing two intermediary quotes

Because intermediaries price within the band rather than at a single program rate, two quotes for the same business can differ by hundreds of dollars. Run each quote exactly as given — its rate, its term, its origination fee — and compare the total cost incl. fee line, not the payments: a lower payment on a longer term usually hides a higher total. Watch the term field especially; a quote stretched to the 84-month maximum minimises the monthly figure while maximising interest, and the total-of-payments output exposes that trade immediately. If one quote sits outside the 8–13% band, that difference — not the payment — is the thing to question.

Frequently asked questions

How much can I borrow with an SBA microloan? Up to $50,000 — that is the program ceiling set by the SBA. There is no program minimum, but in practice intermediary loans start around $500, and the average loan is about $13,000. Needing more than $50,000 means a different product; the microloans guide maps the next step up.

What interest rate do SBA microloans charge? The SBA publishes a band of 8–13% for loans made by its intermediary lenders. Where you land inside the band depends on the intermediary and on the loan’s size and term — smaller, shorter loans usually price toward the top. A quote materially above 13% is not priced inside this program.

What is the average SBA microloan? About $13,000, per SBA program figures. Most borrowers take far less than the $50,000 maximum, which is also why the program’s terms — small balances, terms up to 7 years, intermediary underwriting — are built the way they are.
