Project your Traditional or Roth IRA balance at retirement based on your current balance, contributions and expected return.
Projected Balance at Retirement
$1,280,738
- Years to retirement
- 35
- Total contributions
- $245,000
- Total growth
- $1,015,738
Assumptions
- Traditional and Roth IRAs grow identically inside the account — this projects growth only, not tax treatment
- Does not enforce annual IRS contribution limits
How it's calculated
Future value = principal × (1+r)^n + contribution × ((1+r)^n − 1) / r, compounded monthly.
Worked example
Starting at $20,000 with $7,000/year contributions at a 7% return over decades grows substantially, shown live above.
Frequently asked questions
Should I choose Traditional or Roth?
This calculator doesn't decide that for you — the choice depends on whether you expect your tax rate to be higher now or in retirement. Growth inside the account is modeled the same either way.
