Loan Calculator
Calculate monthly payments and total cost for annuity or equal principal loans.
Loan Calculator
This calculator supports two standard loan repayment structures. With an annuity loan every monthly payment is identical — the share of interest gradually decreases while the principal repaid increases. With an equal-principal loan the principal portion is the same every month, so the total payment and interest decrease over time. Enter the loan amount, annual interest rate, and term in months to see the monthly payment, total amount repaid, total interest cost, and a full month-by-month amortization schedule.
