How it works
Use this calculator to estimate how long it may take to reach one million dollars or another savings target.
What this calculator does
The millionaire calculator projects month by month until savings and investment growth reach the target amount.
It uses:
- current savings
- monthly contribution
- expected annual return
- target amount
Millionaire Formula
Balance = Balance x (1 + Monthly Rate) + Monthly Contribution
Where:
- Balance = running savings balance
- Monthly rate = annual return divided by 12
- Monthly contribution = recurring deposit
- Target = goal amount
Example calculation
If:
- Current savings = 50,000
- Monthly contribution = 1,000
- Annual return = 7%
- Target = 1,000,000
Then:
- Time to target = about 24 years
- Total contributions = about 288,000
- Growth provides the rest of the target
The saver reaches 1,000,000 after sustained saving and compounding.

- shows the role of consistent contributions
- highlights the effect of return assumptions
- helps compare target amounts
When to use this calculator
- planning a long-term wealth goal
- testing monthly contribution amounts
- comparing return scenarios
- estimating age at target
Common mistakes
- assuming high returns without volatility
- ignoring inflation and taxes
- stopping contributions too early
- treating the projection as guaranteed
Millionaire calculator vs future value
A future value calculator shows the balance at a chosen date. A millionaire calculator solves for the time needed to reach a target.
