Investment Calculator
Estimate how your investment could grow over time with regular contributions and compound growth.
Investment Calculator Explanation
An investment calculator estimates how much an investment could grow over time when you combine an initial investment, regular contributions and an expected annual return.
Initial Investment is the amount you invest at the beginning.
Monthly Contribution is the amount you continue adding to the investment every month.
Expected Annual Return is the estimated percentage your investment earns each year.
Investment Period is how long you plan to keep the money invested.
How Investment Growth Works
When investment returns are reinvested, your future returns can also generate returns. This is commonly known as compound growth.
The longer money remains invested and the more consistently you contribute, the more opportunity there is for compound growth to affect the future value.
What This Calculator Shows
The calculator separates the money you personally put into the investment from the estimated growth generated by the assumed return rate.
Initial Investment Monthly Contributions Compound Growth Investment Returns Future ValueExample
Suppose you invest KSh 10,000 initially, contribute KSh 2,000 every month, earn an assumed 8% annual return, and remain invested for 10 years.
The calculator estimates how much you contributed yourself and how much of the final amount represents estimated investment growth.
Change the numbers above to see how different contribution amounts, return assumptions and investment periods affect the estimated future value.
Frequently Asked Questions
What is an investment calculator?
An investment calculator estimates the potential future value of an investment based on an initial amount, regular contributions, expected return and investment period.
What is compound growth?
Compound growth occurs when investment returns remain invested and future returns are calculated on both the original money and accumulated growth.
Does this calculator guarantee investment returns?
No. The calculator is only an estimate based on the return rate entered. Actual investment performance can be higher or lower and can change over time.
Can I include monthly contributions?
Yes. Enter the amount you plan to contribute each month. The calculator includes those contributions when estimating the future value.
Why does the investment period matter?
A longer investment period gives compound growth more time to accumulate, although actual results depend on investment performance.
