Investment Return Calculator
Looking forward? Project how your investments could grow over time with regular contributions. Unlike the basic ROI calculator — which looks back at past returns you already know — this tool helps you plan ahead: enter your starting amount, add regular contributions at any frequency, set an assumed annual return rate, and see your projected future value.

How Investment Projections Work
This tool uses the compound interest formula with periodic contributions to estimate the future value of your investments. It accounts for your initial lump sum, recurring contributions (monthly, quarterly, or annually), and an assumed annual return rate over the selected time horizon.
Future Value = P × (1 + r)n + PMT × ((1 + r)n − 1) / r
Where P = initial investment, r = periodic return rate, n = number of periods, PMT = periodic contribution.
After calculating the projected final value, the tool compares it against your total contributions (initial + all recurring payments) to show your total gain and overall ROI percentage. This forward-looking estimate helps you set savings goals and understand the power of consistent investing over time.
