Formula
How IRA growth is estimated
The calculator compounds your current IRA balance and yearly contributions until retirement, then estimates income using the withdrawal-rate assumption you enter.
Future IRA balance = current balance growth + annual contributions + investment growth
Monthly income estimate = projected balance × withdrawal rate ÷ 12
Planning
Why IRA type and taxes matter
Traditional and Roth IRA contributions can create different tax outcomes. Contribution limits, deductions, eligibility, withdrawals, and RMD rules may vary by account type and tax year.
Annual contribution needed = target gap ÷ future-value contribution factor
After-tax withdrawal = annual withdrawal × (1 − tax rate)

Questions
Frequently Asked Questions
What does this IRA calculator estimate?
It estimates IRA growth, projected balance, inflation-adjusted value, annual retirement income, contribution targets, simplified Traditional versus Roth outcomes, withdrawal longevity, and approximate RMD values from the assumptions you enter.
Can I use it for Traditional and Roth IRAs?
Yes. You can model Traditional, Roth, SEP, and SIMPLE IRA assumptions. The calculator is simplified, so confirm eligibility, deduction rules, contribution limits, and tax treatment with a qualified professional.
How does the withdrawal planner work?
The withdrawal planner subtracts your annual withdrawal, estimates taxes, grows the remaining balance by your return assumption, and checks whether the balance lasts through the life expectancy you enter.
Can this replace financial or tax advice?
No. It is for educational planning only. IRA decisions can depend on income, age, tax filing status, employer plans, contribution rules, investment risk, and withdrawal rules. Review decisions with a qualified advisor or tax professional.
