About Mortgage Payments

A mortgage payment typically consists of four components, often referred to as PITI: Principal, Interest, Taxes, and Insurance.

Principal

This is the amount you borrowed and need to pay back. Each monthly payment reduces your principal balance.

Interest

This is the cost of borrowing money, calculated as a percentage of your remaining loan balance.

Taxes

Property taxes are typically collected monthly with your mortgage payment and held in an escrow account.

Insurance

Homeowners insurance protects your property and is typically required by lenders.

使用本计算器的提示

  • Adjust the loan amount, interest rate, and term to see how they affect your monthly payment.
  • Compare different down payment amounts to find a balance between upfront costs and monthly payments.
  • Use the amortization table to understand how your payments are applied over time.
  • Consider how property taxes and insurance contribute to your total housing costs.

本工具计算什么

每月还款额、总利息支出及还款摊分表。

公式
M = P ×[i(1 + i)ⁿ]÷[(1 + i)ⁿ − 1],i 为月利率、n 为还款期数
计算示例
500 万港元、30 年期、年利率 4%,每月还款约 23,870 港元。
何时使用
落实房贷前,以及比较不同利率或年期时。
常见错误
只看每月还款金额。由 25 年延长至 30 年虽降低月供,总利息却大幅增加。
