GUIDE

How to use this calculator

Use the mortgage calculator to estimate a home-loan payment from the property price, down payment, annual rate, repayment term, and start date. Review the financing ratio, total interest, final payment date, and monthly amortization schedule before comparing options. Results are estimates, not a bank offer.

Calculation method

Mortgage principal = property price − down payment; financing ratio = principal ÷ property price × 100; fixed payment uses the standard amortization formula

How is the mortgage amount calculated?

The estimated mortgage principal is the property price minus the down payment. The calculator then applies the fixed-payment loan formula.

What does the financing ratio mean?

The financing ratio, also called loan-to-value, is the estimated mortgage amount divided by the property price.

Does this include taxes, insurance, or lender fees?

No. This first-release estimate covers the stated principal and interest only. Property taxes, insurance, fees, and changing rates are not included.

Is this a mortgage approval or offer?

No. It is an educational estimate. Actual terms depend on the lender, borrower, property, fees, and local rules.
