About Investment Calculator

Visualize the power of compound interest with our Investment Calculator. Whether you are saving for retirement, a down payment, or just building wealth, this tool helps you verify how your money can grow over time. By inputting your initial principal, regular contributions, and expected rate of return, you can see a clear projection of your financial future. Formula Used: The calculator uses the compound interest formula with regular contributions: Future Value = P × (1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) - 1) / (r/n)] Where: P = Initial principal r = Annual interest rate (decimal) n = Number of times interest applied per time period t = Number of time periods elapsed PMT = Monthly contribution amount
