How to use
Estimate the core monthly payment on a fixed-rate mortgage from the property price, down payment, annual rate and term. The calculator also shows the amount financed, total interest and total loan payments so you can compare scenarios instead of looking only at the monthly figure.
- Enter the full property price.
- Enter the down payment amount you plan to pay upfront.
- Enter the annual rate and loan term, then compare the monthly payment and lifetime cost.
How it is calculated
Example
Example: a property price of 800,000 with a 160,000 down payment leaves 640,000 financed. At a fixed 5% rate for 25 years, the estimated principal-and-interest payment is about 3,741 per month before other costs.
Important notes
This is a planning estimate based on a standard fixed-payment amortization formula. It does not automatically include taxes, insurance, HOA charges, lender fees, mortgage insurance or product-specific rules. A lender’s formal offer remains the reference and this calculator is not a credit approval.
Frequently asked questions
Does a larger down payment reduce the payment?
Usually yes. A larger down payment reduces the amount financed, which generally lowers both the monthly payment and total interest.
Is this the full monthly cost of owning a home?
No. It estimates the core loan payment only; taxes, insurance and other property costs may be additional.
What happens with a shorter mortgage term?
The monthly payment usually rises, but total interest normally falls because the balance is repaid faster.
Is this calculator free?
Yes. It is free to use and requires no account.
