Mortgage Calculator

About the Mortgage Calculator

A mortgage is the biggest loan most people ever take, so a payment that is even slightly too high can strain your budget for decades. Working out the real monthly cost — including taxes and insurance, not just principal and interest — is the first step to buying with confidence.

This Mortgage Calculator estimates your monthly payment and total cost, and can factor in property taxes, insurance and PMI, so you see the true figure before you fall in love with a listing.

How to use the Mortgage Calculator

1. Enter the home price and your deposit or down payment.
2. Add the mortgage interest rate and term.
3. Include property taxes, insurance and PMI if you want the full picture.
4. Read your estimated monthly payment and total cost.

Key features of the Mortgage Calculator

• Estimates the full monthly mortgage payment

• Test different prices, deposits and rates

How the Mortgage Calculator works

This calculator uses the established mathematical formulas that banks, lenders and financial institutions rely on — for interest, amortization, EMI, compounding, tax and investment growth. Where local rules apply (such as tax bands or GST/VAT rates), the tool follows the relevant published structure, and figures can be expressed in the currency you work in.

Every calculation runs in your browser, so the financial figures you enter stay completely private.

Tips & best practices

• Always budget beyond principal and interest — property taxes, insurance and maintenance add a meaningful amount each month.
• A larger deposit lowers your payment, cuts total interest and can remove the need for mortgage insurance.
• Stress-test the payment: make sure you could still afford it if rates rose by a couple of percentage points.

Standards & accuracy

Uses the same standard financial formulas as banks and lenders, with support for multiple currencies and international tax rules.

Disclaimer: results are estimates for general information only and are not financial advice. Rates, fees and tax rules change and vary by provider and jurisdiction. Confirm figures with your bank, lender or a qualified financial professional before making decisions.
