Retirement Needs Calculator
🧓 Retirement Needs Calculator

Retirement Needs Calculator

Estimate the lump sum you’ll need at retirement to provide your desired monthly income (in today’s KES), for a given number of years, after allowing for inflation.
How much you’d like to spend per month in retirement, in today’s shillings.
Roughly how long you expect your retirement to last (e.g. 20–30 years).
Use after-fees returns. The calculator uses a real return (return minus inflation) to estimate how much capital you need.
Estimate from pension, SACCO, investments, etc. Used to show whether you’re over or under your target.
Please enter sensible values: monthly income & years in retirement must be positive.
💡 A common rule of thumb is the “4% rule” – this tool gives a more tailored estimate using your own inflation and return assumptions.
