Türkiye Loan, Deposit and Investment Calculators Added

Hesaplayıcı has five new finance calculators: loan installments, loan early repayment, deposit interest, the credit card minimum payment and investment return. They use the rules in force on 13 September 2026 for KKDF, BSMV, deposit withholding tax, the minimum payment share and the early repayment fee, and they show every result step by step.

What changed

• Loan calculator: the monthly installment, total repayment, interest, KKDF, BSMV and the monthly payment plan. On consumer loans KKDF is 15% (Decision 2010/974) and BSMV is 15% (Presidential Decision 7345).
• Loan early repayment: the remaining principal, the payoff amount and the interest saved. Consumer loans carry no early repayment fee; fixed-rate housing loans carry at most 1% or 2% (Law 6502 art. 27 and 37).
• Deposit interest: gross interest, withholding tax, net interest and the final amount. Since 9 July 2025, TL time deposits pay 17.5% withholding up to 6 months, 15% up to 1 year and 10% over 1 year (Presidential Decision 10041).
• Credit card minimum payment: 20% of the statement balance for cards with a limit of 50,000 TRY or less, 40% above (BDDK Board Decision 10970, 26 September 2024).
• Investment return: the total return, the annualized return (CAGR) and the profit or loss.

The data

The legal rates come from the Official Gazette, BDDK, the central bank and the Revenue Administration. Every calculator page shows the rule it uses and its source.
