Example scenario

Young investor Roth IRA example for 40 years

Final balance $1,349,594

Scenario notes

  • Long time horizons make return assumptions especially sensitive.
  • Small starting balances can still matter when they compound for decades.
  • This example illustrates time in market, not tax or investment advice.

Calculator inputs

Adjust the assumptions

Contribution schedule
Monthly contributions compound monthly; annual contributions are added at year end.
Changing current age updates the retirement-age range and investment horizon.
The calculator derives investment years from current age to retirement age and caps projections at age 100.
This annual amount is $5,000. 2026 IRA limit: $7,500 for this age. Roth eligibility can also depend on income.
Default is a planning assumption, not a forecast. Try 0% to 15% to see how sensitive compounding is.
Optional starting balance already in a Roth IRA.
Used only to estimate a traditional IRA after-tax value. Roth withdrawals are modeled as tax-free.

Assumes contributions are made after tax. Results are estimates and do not include fees, inflation, income eligibility, or changing future law.

Estimated Roth value at age 65$1,349,594
