Mortgage calculator
Estimate your payment, interest, required income and the effect of monthly prepayments.
Mortgage assumptions
The entered rate is a nominal annual rate. This calculator does not calculate APR.
Main result
Early repayment
Strategy: reduce the term
Cash outflow comparison
This compares nominal cash outflows, not which option is a better investment. It excludes maintenance, insurance, taxes, property appreciation, investment returns and inflation.
Payment schedule
Understanding the estimate
What the calculator shows
Payment, interest, total outflow, income burden and the monthly outstanding balance.
How payments are calculated
An annuity payment stays level, while a differentiated payment declines over time.
What interest paid means
It is the interest paid to the bank above the borrowed principal.
How the down payment helps
A larger down payment reduces the loan, payment and interest.
What prepayment does
An extra payment reduces principal, term and future interest.
Payment types
An annuity is normally level. A differentiated loan repays equal principal, so its payment declines.
