About
A monthly mortgage payment does not tell you how much interest you will pay. Mortgage Tracker helps you estimate both and see what regular extra payments could change.
UNDERSTAND YOUR MONTHLY COST
Estimate principal and interest from the property price, down payment, annual rate and repayment period. Choose level payments or equal principal repayments. The full monthly amortization schedule shows payment dates, principal, interest and the remaining balance.
EXPLORE WHAT COULD CHANGE
• Regular monthly extra payments: estimate interest savings and choose between a shorter repayment period and a lower required payment.
• Rent or buy: compare rent, including the annual increase you set, with the down payment and mortgage payments over the loan period.
• Property value: explore a future value based on your own annual growth assumption.
KEEP THE OPTIONS YOU WANT TO REVISIT
Save and rename calculations, adjust their terms later, and sort them by date or monthly payment. Export the baseline payment schedule as PDF to share or CSV to use in a spreadsheet. Choose your currency symbol and light or dark appearance. Designed for iPhone and iPad.
Basic calculations and viewing the schedule are free. Free scenario recalculations, exports and saved calculations have limits. Monthly or yearly Pro subscriptions remove those limits and disable advertising when enabled.
For information and planning only; not financial advice or a lending offer. Estimates exclude taxes, insurance and fees, and use a constant annual rate with monthly interest calculated as the annual rate divided by 12. Results may differ from your lender's contract. Rent versus buy compares cash outflows, not total investment returns. Property growth is an assumption you provide, not a market forecast.
