Compound Interest Calculator Kenya
Methodology
Compound interest is the cornerstone of wealth creation in Kenya, famously utilized in Capital Markets Authority (CMA) regulated Money Market Funds (MMFs) and deposit-taking SACCOs. Kenyan MMFs (such as Sanlam, CIC, Britam, Cytonn, Stanbic, and NCBA) calculate interest daily based on published effective annual yields (currently 12% to 15.5% p.a.) and credit earnings monthly. Under the Income Tax Act, interest earned by resident individuals is subject to a statutory 15% Withholding Tax (WHT), which is deducted at source. This calculator models initial principal, regular monthly deposits, compounding frequency (daily, monthly, annually), and computes both gross interest and net after-tax wealth.

Frequently asked questions
What are the top Money Market Funds (MMFs) in Kenya and their returns?
Leading CMA-regulated Kenyan MMFs include Sanlam, CIC, Britam, Cytonn, Stanbic, NCBA, KCB, and Apollo. Current nominal annualized yields range between 12.0% and 15.5% per annum.
How is Withholding Tax (WHT) applied to MMF and savings interest in Kenya?
Under the Kenya Income Tax Act (Cap 470), interest income earned on MMF investments and bank fixed deposits is subject to a 15% Withholding Tax (WHT) deducted at source as a final tax. Infrastructure bonds (IFBs) are notable exceptions that are 100% tax-exempt.
How does daily compounding work in Kenyan Money Market Funds?
Kenyan MMFs accrue interest on your account balance on a daily basis using the daily rate: (Annual Effective Rate ÷ 365). At the end of each calendar month, the accrued net interest is reinvested into your fund units, compounding future returns.
How does compounding in an MMF compare to a Kenyan SACCO?
MMFs offer daily liquidity, capital preservation, and daily compounding at ~12%–15% with 15% WHT. SACCOs require committed monthly deposits, pay annual dividends (typically 10%–14%), and offer 3x–4x borrowing leverage for development loans.
What is the difference between simple interest and compound interest?
Simple interest earns returns only on the initial principal. Compound interest earns interest on both the principal and the accumulated interest from previous periods, leading to exponential wealth accumulation over time.
