This loan calculator helps you estimate monthly payments, total interest costs, and view a complete amortization schedule for any fixed-rate loan.

Equal installment (本息等额) keeps the same total monthly payment throughout the loan, with more interest paid early and more principal paid later. Equal principal (本金等额) keeps the principal portion fixed, so monthly payments decrease over time as less interest accrues on the shrinking balance.
For equal installment loans, the monthly payment is calculated using the formula: PMT = P × [r(1+r)^n] / [(1+r)^n - 1], where P is the principal, r is the monthly interest rate, and n is the total number of payments.
An amortization schedule is a table showing each payment broken down into principal and interest portions, plus the remaining balance after each payment. It helps you see exactly how much interest you'll pay over the life of the loan.
No, this calculator shows principal and interest only. Property taxes, homeowners insurance, and PMI are not included. For a complete monthly housing cost estimate, add those amounts separately.
