Loan Calculator: Estimate Your Monthly Payments
This loan calculator helps you estimate monthly payments for personal loans, auto financing, or any installment loan with a fixed rate and term. Enter the loan amount, annual interest rate, and term to see your monthly obligation.
Formula
The formula is Monthly Payment = P × (r(1+r)^n) / ((1+r)^n − 1), where P is the principal, r is the monthly interest rate (annual rate / 12), and n is the total number of payments. This is the standard amortization formula used by lenders.
Worked example
A 10,000 loan at 8% annual interest over 5 years (60 monthly payments) results in a monthly payment of about 202.76. Total repayment is roughly 12,166, with 2,166 going to interest.
Practical guidance
Understanding amortization
Early in the loan term, most of each payment goes toward interest. Over time, more goes toward principal. This calculator gives you the fixed monthly payment amount. For a full amortization schedule showing payment-by-payment breakdown, use a dedicated amortization tool.
Rate comparisons and shopping
Small changes in interest rate have large effects over the life of a loan. At 10,000 over 5 years: 5% rate = monthly 188.71; 8% = 202.76; 12% = 222.44. Compare offers before committing.
What this calculator does not include
Real loan offers may include origination fees, insurance, prepayment penalties, or variable rates. This calculator shows the mathematical amortization — always confirm the final terms with your lender before signing.
