Enter a loan amount greater than zero.
What is the business loan payment calculator?
This is a focused version of our business loan calculator. Enter a loan amount, rate and term to see your estimated monthly payment instantly — or use the built-in reverse calculator to answer the more useful question: “how much can I afford to borrow?”
Two ways to use it
- Monthly payment: enter the loan amount to get the payment, total interest and total repayment.
- What can I afford? enter your maximum comfortable monthly payment and the calculator returns the largest loan amount that payment supports at your rate and term.
How it works
- Payment = P × r ÷ (1 − (1 + r)^−n)
- Maximum loan = Payment × (1 − (1 + r)^−n) ÷ r
Here r is the monthly rate (annual rate ÷ 12) and n is the number of monthly payments. Both directions use the same underlying loan engine, so the numbers are always consistent — the affordability answer, run forward, reproduces your payment.
Example
A $100,000 loan at 6% over five years is about $1,933 a month. Working backwards, a maximum payment of $1,933 a month at the same rate and term supports a loan of about $100,000 — the two views are mirror images.

Frequently asked questions
How is my monthly loan payment calculated?
The monthly payment on an amortizing loan is P × r ÷ (1 − (1 + r)^−n), where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12) and n is the number of monthly payments.
How much can I afford to borrow?
Switch to the affordability mode, enter the maximum monthly payment you're comfortable with, plus the rate and term, and the calculator works backwards to the largest loan that payment supports.
Does a longer term reduce my payment?
Yes — spreading the loan over more payments lowers each one, but you pay interest for longer, so the total cost of the loan rises.
What interest rate should I use?
Use the annual percentage rate your lender quotes. If you're comparing offers, run each rate to see how it changes the payment and total interest.
