Bond and Eurobond Coupon Withholding Calculator
Calculate coupon amounts, gross interest, withholding tax and net interest for bonds and eurobonds.
Things to keep in mind

- Eurobond interest is generally not subject to Turkish withholding and may have to be declared in the annual return; declaration is not calculated here.

About this tool
Each coupon equals nominal × annual coupon rate / coupons per year. Foreign-currency coupons are converted to TRY at the collection-date rate. Because Turkish withholding rates depend on the instrument and issue date, you enter the rate.
How to use
- Enter the nominal amount and the annual coupon rate.
- Enter the number of coupons per year and how many coupons to calculate.
- For foreign-currency bonds enter the exchange rate (leave 1 for TRY bonds).
- Enter the withholding rate and press Calculate.
Notes
The coupon per payment is rounded to cents in TRY; gross interest is the coupon times the number of coupons. Capital gains on early sale, currency gains and redemption differences are not included.
Frequently asked questions
