The Investment Return & Growth Calculator helps you estimate the future value of your money. By entering your initial investment, monthly contributions, annual return rate, and years invested, you can project how your wealth will grow over time.
It’s an essential tool for anyone saving for retirement, education, or long-term financial goals.
🔹 Formula Used
The calculator uses the future value with contributions formula: FV=P(1+r/n)nt+C×(1+r/n)nt−1r/nFV = P(1 + r/n)^{nt} + C \times \frac{(1 + r/n)^{nt} - 1}{r/n}FV=P(1+r/n)nt+C×r/n(1+r/n)nt−1
Where:
- FV = Future Value
- P = Initial Investment (Principal)
- C = Monthly Contribution
- r = Annual Interest Rate (decimal)
- n = Compounding periods per year (12 for monthly)
- t = Years
🔹 How to Use the Calculator
- Enter your initial investment (starting amount).
- Input your monthly contribution.
- Add your expected annual return (%).
- Enter the number of years you plan to invest.
- Click Calculate to see your investment’s future value.
🔹 Example Calculation
