How this calculator works
This calculator estimates monthly payments for fixed-rate personal, student, or business loans. Enter the loan amount, annual interest rate, and term in years to see the fixed monthly payment and total interest. Use it when comparing loan offers, checking affordability, or planning repayment schedules. The key inputs are the principal amount, annual interest rate, and loan term in years. The output is the monthly payment, total payments, and total interest. Real-world applications include personal loans, auto financing, debt consolidation, and education loan planning. The calculator uses the standard fixed-rate amortization formula. It does not include fees, insurance, origination charges, or variable-rate adjustments. Compare the total interest across different terms to see how a longer repayment period increases the overall cost.
