Simulation assumptions
- Cash flows are modeled to maturity with no reinvestment of coupons.
- Future cash flows use a projected exit FX rate of 138 KES/USD.
- A 10.00% withholding tax is applied to coupons only.
Educational estimate only. It excludes transaction fees, default risk, liquidity constraints, changing market prices, and product-specific tax rules beyond the withholding rate you enter.

Calculator guide
Frequently asked questions
What does the FX scenario calculate?
Entry and projected exit rates are expressed as local-currency units per US dollar. The calculator converts the initial investment at the entry rate and future cash flows at the projected exit rate to show the modeled currency impact.
Is coupon interest calculated from price or face value?
Coupon interest is calculated from face or par value. For coupon bonds, the calculator separately handles clean price, accrued interest and dirty purchase price.
Are the projected returns guaranteed?
No. Results are educational scenarios. Actual outcomes can change because of default, liquidity, market prices, taxes, fees, inflation and currency movements.
