Law No. 3095 Arts. 1–2 · Rates retrieved automatically from the Central Bank of Türkiye (CBRT)How Are Statutory and Commercial Interest Calculated?
With the amendment of 31 July 2026 to Law No. 3095 on Statutory Interest and Default Interest, the statutory interest rate was linked to the Central Bank rediscount rate. Accordingly, statutory interest is 80% of the rediscount rate in force on the last day of the previous year. In commercial matters, the Central Bank short-term advance rate may be claimed as default interest. Interest is calculated separately for each period at the rate in force in that period; the calculator splits these periods automatically.
