Monthly payment
Your estimated principal and interest payment each month.
Total interest
The estimated borrowing cost over the full loan term, excluding fees.
Total repayment
Your loan amount plus estimated interest over the full term.
Estimates are for educational purposes and are not loan offers. This calculator assumes a fixed annual interest rate, equal monthly payment periods, and the first payment one month after funding. It excludes fees, variable rates, balloon structures, and extra payments. Amounts are rounded for display; totals use unrounded calculations. Actual lender calculations and terms may differ. Your entries stay in this calculator and are not sent to our financing partner.
How to Use the Business Loan Calculator
1. Enter Your Loan Amount
Enter the amount you plan to borrow. Try different amounts to see how financing a larger or smaller portion of your business needs changes the payment.
2. Add an Annual Interest Rate
Use a lender’s quoted interest rate or enter an assumed rate to explore a scenario. The calculator keeps this rate constant throughout the loan term.
3. Choose Your Repayment Term
Enter the repayment period in months or years. Compare several terms to understand the balance between monthly payments and total interest.
4. Review Your Results
Select Calculate to see your estimated monthly payment, total interest, and total repayment. Expand the repayment schedule for a monthly breakdown or download it as a CSV file.

What Your Results Mean
Monthly Payment
Your estimated monthly payment includes principal—the amount you borrowed—and interest. The calculator assumes equal monthly payments over the selected term.
Total Interest
This is the estimated interest paid over the life of the loan. It does not include origination fees or other lender charges.
Total Repayment
This is the original loan amount plus estimated interest. Use it alongside the monthly payment to understand the full repayment commitment modeled by the calculator.
Repayment Schedule
The schedule shows how each monthly payment is divided between principal and interest, along with the remaining balance.
Business Loan Payment Example
For a $100,000 loan with a 10% annual interest rate and a five-year repayment term, the calculator estimates:
| Result | Estimated amount |
| Monthly payment | $2,124.70 |
| Total interest | $27,482.27 |
| Total repayment | $127,482.27 |
This example assumes a fixed interest rate, 60 monthly payments, and no fees or extra payments. Amounts are rounded, and the lender’s actual calculations may differ. The example is not a financing offer.
Compare Monthly Payments and Total Cost
For the same loan amount and interest rate, extending the repayment term generally lowers the monthly payment but increases total interest.
A shorter term generally means higher monthly payments and less total interest. Try both scenarios to understand the trade-offs before exploring financing.
You can also use our Loan Comparison Calculator to review two loan scenarios side by side.
Calculator Assumptions
This calculator models a fixed-rate loan repaid through equal monthly payments, with the first payment due one month after funding.
It does not account for lender fees, changing interest rates, extra payments, balloon payments, or daily and weekly repayment schedules. Use the results as planning estimates and compare them with the terms in any actual financing offer.
Frequently asked questions
Yes. You can use it for free to estimate payments and explore different loan amounts, interest rates, and repayment terms.
The calculator uses the loan amount, annual interest rate, and number of monthly payments to estimate a fixed payment that repays both principal and interest over the selected term.
Enter the annual interest rate quoted by a lender, if you have one. Otherwise, test several assumed rates to explore possible costs. An assumed rate is not an indication of the rate you will qualify for.
This calculator uses the loan’s annual interest rate. APR can reflect certain financing fees in addition to interest. Entering APR in place of the interest rate may not reproduce a lender’s payment calculation.
No. Origination fees, closing costs, and other lender charges are excluded. Review those charges separately when comparing offers and calculating the overall cost of financing.
For the same amount and interest rate, a longer term generally reduces the monthly payment but increases total interest. A smaller payment does not necessarily mean a less expensive loan.
Yes. Expand the repayment schedule to see the principal and interest portions of each payment and the estimated remaining balance. You can also download the schedule as a CSV file.
This version assumes scheduled monthly payments only. It does not model extra principal payments or an early payoff.
