Calculate mortgage monthly payments, total interest, and repayment plans online. Supports equal payment and equal principal methods, as well as combined commercial and provident fund loans.
Equal Payment (等额还款) keeps your monthly payment fixed throughout the loan. Equal Principal (等额本金) pays the same principal each month, so your payment decreases over time — you pay less total interest but higher initial payments.
For first-time homebuyers in most Chinese cities, the minimum down payment is 20%. Some cities and loan types may require 30% or more.
For Equal Payment: M = P × r × (1+r)^n / ((1+r)^n - 1), where P is loan principal, r is monthly interest rate (annual rate / 12), and n is total months.
Equal-payment (annuity): fixed monthly payment, high interest and low principal repayment early on, stable and easy to budget, slightly higher total interest paid. Equal-principal: fixed monthly principal, decreasing interest, higher early payments that decrease over time, lower total interest — better for higher-income borrowers who plan to prepay. In most countries, lenders default to equal-payment; both options are usually available for commercial loans.
