About this tool
Under Law No. 6183 art. 48, a Turkish public receivable may be deferred against security for up to 36 months, with annual deferral interest. This tool assumes equal principal instalments, the first one month after deferral, with simple interest on each instalment for the months until it is paid, which equals interest on the declining balance.
How to use
- Enter the amount to defer.
- Enter the number of monthly instalments (up to 36).
- Press Calculate.
Notes
Estimate: interest on instalment k = (debt / n) × annual rate / 100 × k / 12; total interest = debt × annual rate / 100 × (n + 1) / 24. The tax office calculates by days, so official amounts may differ slightly.
