How Monthly Investing Builds Wealth Over Time
Monthly investing combines recurring contributions with compounding. The result is driven by contribution size, time and realized returns.

Open the calculatorContributions versus growth
Early in a savings journey, contributions often account for most of the balance. Over longer periods, investment growth can become a larger share.
Automate the behavior
Automatic contributions reduce the need to make a new decision every month and can make savings increases easier to sustain.
Do not overfit the return
Test a range of returns. The calculator can show mathematical outcomes, but markets do not provide a smooth fixed return.
How to use this number responsibly
Use the result as a planning range rather than a forecast. Re-run the calculation when your balance, contribution rate, debt, retirement date, tax situation or spending target changes. For investment projections, compare multiple return assumptions because future market returns are unknown.
What this calculator does not know
RetirementMetric does not know your complete tax situation, benefits, investment holdings, insurance needs or household expenses. The tools are educational estimates, not individualized investment, tax or legal advice.
