What Is the Investment Forecast Calculator?
The Investment Forecast Calculator is a free online tool designed to estimate the future value of an investment using compound interest. By entering your initial investment amount, annual interest rate, and investment duration in years, you’ll instantly see how your money could grow.

- Input the Annual Interest Rate
- Add the expected yearly return percentage from your investment. For example, if you anticipate a 6% annual return, type “6.”
- Specify the Number of Years
- Enter how long you plan to keep your money invested. For example, “10” for ten years.

Practical Example
Let’s say you want to invest $10,000 in a mutual fund with an expected annual return of 7% over 15 years.
- Principal = $10,000
- Annual Interest Rate = 7%
- Years = 15
When you click Calculate, the result will show the future value:
Future Value = $27,590.40
That means your $10,000 investment could grow to nearly $27,600 in 15 years—without adding anything more. This highlights the power of compounding over time.

FAQs About the Investment Forecast Calculator
1. What formula does the calculator use?
It uses the compound interest formula:
Future Value = Principal × (1 + Rate) ^ Years.
2. Can I use decimals for interest rates?
Yes, you can enter rates like 5.5% or 6.25%.
3. Does this calculator include additional contributions?
No, it calculates based on a single initial investment (principal).
4. What if I want to calculate monthly contributions?
For recurring deposits, you would need a compound interest with contributions calculator, which is a more advanced version.
5. Does it account for inflation?
No, this tool shows nominal returns without adjusting for inflation.
6. Is the result guaranteed?
No, the result is an estimate. Actual investment returns vary depending on market performance.
7. Can I calculate negative interest rates?

8. What’s the minimum input amount?
You can start with any positive number above zero, even small investments like $100.
9. What’s the maximum input amount?
There’s no strict maximum, but very large numbers may be harder to interpret realistically.

This calculator assumes annual compounding only.
11. How accurate is the calculation?

12. Can I use it for short-term investments?

14. Can I compare two different scenarios side by side?
Not directly, but you can calculate one, reset, then input the second set of values to compare results manually.
15. Does this replace professional financial advice?
No, it’s a helpful tool for estimates, but you should still consult a financial advisor for tailored advice.
16. How does compound interest differ from simple interest?
Compound interest grows on both your original investment and the accumulated interest, while simple interest grows only on the principal.

No, all fields reset once you reload the page.
19. Can I share the results?
