Mortgage calculator online
Estimate your monthly payment and overpayment. Annuity payment schedule by month.
Mortgage parameters
The calculation uses the entered amount as the loan principal (down payment is not deducted).
Other financing options
Compare consumer loans and microloans while you choose a mortgage program at your bank.
How the mortgage calculator works
Enter the property value (used as the loan amount in this simplified model), the term in years, and the annual interest rate. The calculator shows the annuity monthly payment, total to repay, interest overpayment, and a detailed payment schedule.
The first payment in the schedule is due one month after the loan start; each row shows principal, interest, and remaining balance. This helps you understand how the debt decreases over time.
Actual bank offers may include insurance, fees, and a required down payment — always confirm terms with the lender. Below you can compare other credit products on CreditDeals.
Annuity mortgage payments
With an annuity loan, the monthly payment stays the same for the whole term. Early payments are mostly interest; later payments repay more principal. Our calculator uses this standard model.
