What Is an Investment Calculator?
An investment calculator helps you understand how your money grows over time. It uses compound interest, contribution patterns, and your expected return rate to estimate your future wealth.
Investment Growth Formula
The formula for compound investment growth is:
A = P(1 + r/n)^(nt) + Contribution Growth
Where:
- P = Starting amount
- r = Annual return rate
- n = Compounding frequency
- t = Years invested
Example Calculation
If you invest $20,000 for 10 years at a 6% annual return, compounded annually, with $1,000 yearly contribution, your projection may look like:
- End Balance: $198,290.40
- Total Contributions: $120,000.00
- Total Interest Earned: $58,290.40
Why Use an Investment Calculator?
- Plan retirement savings
- Estimate future portfolio value
- Compare investment scenarios
- Understand compound returns
- Make informed financial decisions
Simple Interest vs. Compound Investment Growth
Simple interest grows at a fixed rate only on the original principal. Compound interest grows faster because it earns interest on interest.
