Investment calculator for future value, contributions, return rate, or investment length. Includes compounding, payment timing, chart, and accumulation schedule.
What Is an Investment Calculator?
An investment calculator projects how an initial investment and recurring contributions can grow with a compound return. It answers questions like how much will my investment be worth, what return rate do I need, or how long will it take to reach a target balance.
The calculator can solve for whichever value you're missing: starting amount, contribution, ending balance, length, or return rate. You can set annual, quarterly, or monthly contributions, choose whether they're made at the start or end of each period, pick a compounding frequency, and review the result as an ending balance, contribution total, interest earned, chart, and accumulation schedule.
Investment Growth Example
Start with $10,000, contribute $1,000 a year, and earn a 6% annual return for 10 years: the projected ending balance is about $31,089. Of that, $20,000 is your own money (initial amount plus contributions), and about $11,089 is investment growth.
Recurring Contributions and Return Rate Planning
If you invest a fixed amount every month rather than a lump sum, set the contribution frequency to monthly and use the same fields to track that recurring investment over time. If instead you already know your target balance and want to know what return you'd need to get there, select Return as the value to solve for and the calculator works backward from your goal.
