How Much Should I Invest Each Month to Reach My Goal?
Set your own target instead of starting with a fixed $1 million goal. The calculator estimates the monthly contribution that could reach it under your assumptions.
Calculate your monthly target
Assumes monthly compounding and end-of-month contributions.
How to use an investment goal
Start with the amount you already have, choose a target and time horizon, then enter an assumed annual return. Try several assumptions rather than treating one result as a promise.
Why this differs from the $1 million calculator
The math is the same goal-seeking model, but this page is designed around any target: 100,000, 250,000, 500,000, 1 million or another amount meaningful to you. Our existing $1 million guide remains a focused example.
What the calculator assumes
Returns are modeled at a constant annual rate compounded monthly, with contributions at the end of each month. Taxes, fees and real-world market volatility are not modeled.
