How METRIKA calculates this
Savings compound monthly at the investment return, with the monthly contribution added at the end of each month and raised once a year. The balance in today's money divides by (1 + inflation)^years.
Retirement income uses the 4% rule: withdrawing about 4% of the portfolio a year has historically lasted around 30 years. It is a rough guide, not a guarantee. The Freedom Score compares that income with your spending today (100 = fully covered).
What to know in Kenya
Kenyan savers commonly use money market funds, Treasury bills and bonds, SACCO deposits, NSSF and occupational pensions. Interest from these is usually taxed at 15% withholding tax, with infrastructure bonds tax-free. Returns in the model are before tax and fees, so use a net figure if you know it. Inflation was 6.5% in July 2026 (KNBS, via CBK).
Frequently asked questions
What return should I assume?
Use a return a little above inflation for cautious savings, and higher only for long-term diversified investing. Past returns don't predict future ones.
What is the 4% rule?
A guide that says withdrawing about 4% of your savings in the first year of retirement, then adjusting for inflation, has usually lasted around 30 years.
Does NSSF count?
Yes. Add your NSSF and pension balances to today's savings, and include your monthly NSSF contributions in monthly saving.
