Mortgage Loan Calculator
Calculate the mortgage loan installment and total cost using home price, down payment, interest rate, and maturity information.
Monthly installment = P × r × (1+r)^n / ((1+r)^n - 1). P: loan amount, r: monthly interest rate, n: maturity in months.
The calculation is based on the fixed installment loan/amortization formula. Since CBRT (TCMB) interest data, bank campaigns, BRSA (BDDK) decisions, and regulations published in the Official Gazette may change, interest and fee fields are left as user input.
This tool is prepared for estimated informational purposes. For appraisal, mortgage, insurance, allocation, and loan usage conditions, the official offer of the bank and the current legislation should be taken as a basis.
Frequently Asked Questions
How is the mortgage loan installment calculated?
The fixed installment amortization formula is applied using the loan amount, monthly interest rate, and maturity. While the total installment paid each month remains constant, the interest and principal share change over time.
Why is the down payment important?
As the down payment increases, the loan amount to be used decreases. This generally reduces the monthly installment, total repayment, and total interest cost.
Are appraisal and mortgage fees included?
In this tool, one-time fees can be entered by the user. Because they may vary according to the bank and transaction type, they are not assumed to be fixed.
