Millionaire Calculator — When Will I Reach $1 Million?

Enter what you already have, what you can invest each month, and an assumed return. See how long it could take to reach $1 million—or change the target to model $250,000, $500,000, $2 million, or another milestone.

Your path to the goal

The sample values are calculated automatically. Change the assumptions to see your own estimate.

These calculators provide mathematical planning estimates, not financial, tax, legal, or investment advice. Actual rates, returns, fees, taxes, market values, and lender practices can change the result.

Understand the result

A target-date calculator built around time and compounding

This calculator solves the question in the direction most people actually ask it: “If I keep doing this, when could I get there?” It compounds the current balance monthly, then adds the entered contribution each month until the target is reached.

The result separates money you contributed from modeled investment growth so you can see how much of the goal depends on time and return assumptions.

Use conservative assumptions

  • Try more than one return assumption instead of relying on a single optimistic number.
  • Increase the monthly contribution to see how much time you can save.
  • Change the target to compare milestones without opening a different calculator.

Frequently asked questions

Is a 7% return guaranteed?

No. Any return entered is only a modeling assumption. Market returns vary and can be negative.

Can I use a target other than $1 million?

Yes. The target amount is editable, so the same calculator can model any savings or investment milestone.

Does the calculator include taxes or investment fees?

No. It models gross growth before taxes and fees unless you reduce the return assumption to reflect those costs.
