How do you calculate future value of a lump sum?

The formula is FV = P × (1 + r)n, where P is the principal (starting amount), r is the annual interest rate as a decimal, and n is the number of years. For example, KES 1,000,000 at 12% for 10 years: FV = 1,000,000 × (1.12)10 = KES 3,105,848. Use the calculator above to get your exact number instantly.

What return rate should I use in Kenya?

Use the rate that matches your investment vehicle. Money market funds in Kenya offer 8–12% annually. Treasury Bills yield 14–17%. Unit trusts (balanced) return 10–15%. Fixed deposits offer 6–10%. For equity investments, historical returns are 12–18% but with higher risk. Always pick a realistic rate for your chosen product.

What is the difference between future value and present value?

Future value tells you what money today will grow into. Present value does the reverse — it tells you what future money is worth now. They use the same formula rearranged: FV = PV × (1 + r)n and PV = FV ÷ (1 + r)n. Use this calculator for growth projections and the Present Value Calculator to discount future cash flows.

Q: How does compound interest affect future value?

Compound interest is the engine behind future value growth. Unlike simple interest which only earns on the original amount, compound interest earns returns on your returns. KES 1,000,000 at 10% simple interest earns KES 100,000 per year (flat). With compounding, year 1 earns KES 100,000, year 2 earns KES 110,000, year 3 earns KES 121,000 — each year more than the last. Over 20 years, this snowball effect turns KES 1M into KES 6.7M. See the full effect with the Compound Interest Calculator.

Enter a lump sum, your expected annual return, and a time period. We’ll show you exactly how much your investment will be worth — powered by compound interest.

Updated April 2026

Future value tells you how much a lump sum of money will be worth after growing at compound interest over a given period. The formula is FV = P × (1 + r)ⁿ. For example, KES 1 million invested at 10% annual return for 5 years grows to approximately KES 1,610,510. That extra KES 610,510 is the power of compound growth — your returns earning returns.

How the Future Value Formula Works

Future Value

Principal

Years

The future value formula calculates how much a lump sum will grow over time when invested at a compound annual return. You multiply the principal by the growth factor (1 + r)ⁿ, which accounts for interest earning interest each year.

The higher the return rate and the longer the time period, the larger your future value — because compound interest creates exponential growth. This is the flip side of present value, which discounts future money back to today. Together, they form the foundation of time value of money analysis.

Future Value Calculator — FAQ

Future value is how much a lump sum of money today will be worth at a specific point in the future, after earning compound interest. It matters because it shows you the real growth potential of your savings and investments. For example, KES 500,000 invested at 10% annual return grows to about KES 805,255 in 5 years — that extra KES 305,255 is the power of compounding at work.

Compound interest is the engine behind future value growth. Unlike simple interest which only earns on the original amount, compound interest earns returns on your returns. KES 1,000,000 at 10% simple interest earns KES 100,000 per year (flat). With compounding, year 1 earns KES 100,000, year 2 earns KES 110,000, year 3 earns KES 121,000 — each year more than the last. Over 20 years, this snowball effect turns KES 1M into KES 6.7M. See the full effect with the Compound Interest Calculator.

Yes — calculate the future value of the same lump sum across different investments and timelines to see which grows your money the most. For example, KES 1,000,000 in a money market fund at 10% for 5 years grows to KES 1,610,510, while the same amount in T-Bills at 15% grows to KES 2,011,357. The KES 400,847 difference helps you weigh higher returns against lower liquidity. Track your overall financial position with the Net Worth Calculator.
