How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

This calculator projects investment growth by compounding an initial investment plus regular monthly contributions at a given annual return rate over a chosen time horizon.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

What is a realistic annual return?

Historically, diversified stock market indices have returned around 7–10% annually before inflation over long periods, but past returns do not guarantee future results.

Does this account for taxes?

No. This is a gross projection. Actual returns depend on tax treatment, fund fees, and market conditions.
