Good to know
Good to know
The mortgage calculator works out the monthly payment for a home loan from property price, down payment, interest rate, and term - and goes beyond a plain annuity formula: you can set a fixed-rate period shorter than the full term, pay closing costs in cash or finance them, add recurring housing costs such as property tax, insurance, and association fees, and model a monthly extra payment.
Typical searches include mortgage calculator, home loan calculator, and extra payment mortgage calculator. Calculation runs fully locally in the browser, and you can download the complete amortization schedule as a CSV. Taxes, notary fees, and regional programs are not estimated automatically and should be checked separately.
Typical use cases
Plan a fixed-rate period shorter than the term
Enter a fixed-rate period shorter than the full term and see the remaining balance plus the interest and principal paid by then - useful for assessing the rate risk at refinancing realistically.
Model extra payments
Add a monthly extra payment and see immediately how much interest you save and how much sooner the loan is paid off - as a concrete figure rather than a vague estimate.
Compare total housing cost, not just the payment
Add property tax, insurance, and association fees to see the actual monthly cost - not just the loan payment, which can be misleading when comparing different properties.
Tips for better results
Plan realistically for refinancing
Recalculate the remaining balance at the end of the fixed-rate period with a higher interest rate, not just the current one, so you see early whether the follow-up payment stays affordable if rates rise by then.
Check extra-payment rights in the contract
Many loan contracts cap free extra payments at a percentage per year. Check that limit before actually making an extra payment you simulated here.

Features
Fixed-rate period separate from the term
Model a shorter fixed-rate period independent of the full term and see the remaining balance, interest paid, and principal paid at the end of that period.
Extra payments with real savings
A monthly extra payment shows concretely how much interest and how much time it saves over the term.

Frequently asked questions
Frequently asked questions
What’s the difference between the fixed-rate period and the loan term?
The term is the total time until the loan is fully repaid. The fixed-rate period can be shorter; afterward the loan is typically refinanced on new terms. The calculator shows the remaining balance exactly at that point.
Does the calculator include property tax and insurance?
Yes, optionally: you can add property tax, building and mortgage insurance, association fees, and other recurring costs to see the actual monthly cost. These figures do not change the loan’s own amortization schedule.
Can I calculate extra payments?
Yes. Enter a monthly extra payment and the calculator shows the interest saved and the shortened remaining term. Check beforehand whether your loan contract allows free extra payments of that size.
