Taking a business loan is a major financial decision that can help your company grow, invest in new assets, or manage cash flow. Understanding how to repay the loan — including the breakdown of principal and interest — is critical for budgeting and financial planning.
A Business Loan Amortization Calculator is a valuable tool that helps borrowers see their payment schedules clearly. It calculates monthly payments, interest paid over time, and the remaining balance after each payment. This tool makes loan management transparent and manageable for business owners, accountants, and financial planners.

How to Use the Business Loan Amortization Calculator
- Enter the Loan Amount – The total principal borrowed.
- Enter the Annual Interest Rate (%) – The yearly interest rate charged by the lender.
- Enter the Loan Term – Length of the loan in months or years.
- Choose Payment Frequency – Usually monthly, but some calculators offer weekly or biweekly options.
- Click ‘Calculate’ – View the monthly payment amount and the full amortization schedule showing principal, interest, and balance over time.
Loan Amortization Formula
The formula to calculate the fixed monthly payment is:
M = P × (r(1 + r)^n) / ((1 + r)^n − 1)
Where:
- M = Monthly payment
- P = Principal loan amount
- r = Monthly interest rate (annual rate divided by 12 and converted to decimal)
- n = Total number of payments (loan term in months)
Example Calculation
Example:
- Loan Amount (P) = $50,000
- Annual Interest Rate = 6% (0.06)
- Loan Term = 5 years (60 months)
Monthly interest rate, r = 0.06 / 12 = 0.005
M = 50,000 × (0.005 × (1 + 0.005)^60) / ((1 + 0.005)^60 − 1)
M ≈ $966.64
This means you pay $966.64 every month for 5 years.
Understanding the Amortization Schedule
The amortization schedule breaks down each monthly payment into:
- Principal Payment – Portion that reduces the loan balance.
- Interest Payment – Portion that pays the interest to the lender.
- Remaining Balance – Loan amount left after payment.
Early payments mostly cover interest, while later payments contribute more to the principal.
