Inflation Calculator
See what today's money could be worth — or cost — years from now, starting from the latest published inflation figure.
What inflation could do to your money
Enter an amount and your own inflation assumption — pre-filled from the latest published rate — to see its effect over time.
- What KES 100,000 today could cost in 10 years
- KES 185,959
- If KES 100,000 sat in cash for 10 years instead, it would only buy what this is worth today
- KES 53,775

How inflation erodes purchasing power
Inflation is the rate at which prices for goods and services rise over time. It doesn't take money away directly — instead, the same nominal amount simply buys progressively less as prices climb, so a shilling saved today is worth less, in what it can actually purchase, than the same shilling a decade from now. That's true even for money sitting untouched in a bank account: if the rate it earns is lower than inflation, it's still losing purchasing power in real terms.
This calculator shows two distinct sides of that effect from the same starting amount and rate. The first figure is a future nominal cost — what buying the same basket of goods you could buy for that amount today would cost you years from now, if prices keep rising at the rate you enter. The second figure runs the same rate in reverse: it's the real, inflation-adjusted value of that amount if it sat idle in cash for the same period instead — in other words, how much of today's purchasing power that pile of shillings would actually retain.
Kenya's latest published inflation rate
| Measure | Value |
|---|---|
| Consumer price inflation, year-on-year | 6.41% |
Source: Central Bank of Kenya — consumer price inflation, as of 30 June 2026. The calculator pre-fills its rate field with this figure rounded to one decimal place (6.4%) as an editable starting assumption, not a forecast of where inflation is headed.
Worked example: KES 100,000 over 10 years at 6.4%
Take the calculator's own defaults: KES 100,000 today, a 6.4% assumed annual rate, over 10 years. Projected forward, the same basket of goods you could buy for KES 100,000 today would cost KES 185,959 in 10 years, as prices compound upward at 6.4% a year. Run the same rate in reverse, and KES 100,000 held in cash for those 10 years, earning nothing, would only be able to buy what KES 53,775 buys today — a little over half its current purchasing power. Both figures come from the same 6.4% assumption; they're simply applied in opposite directions from the same starting point.
As the calculator notes, the pre-filled rate is a dated historical snapshot, not a prediction — actual inflation over your chosen period may run higher or lower, so it's worth testing more than one assumption rather than treating either result as certain.
