What this calculator shows
Traditional IRA growth depends on what is already in the account, what you keep contributing, and how long the balance stays invested.
This page is best for first-pass retirement planning when you want the balance projection without pretending to model every IRA tax rule.
How to use it
- 1. Add the balances already sitting in the Traditional IRA.
- 2. Use an average monthly contribution pace that matches the annual funding plan you expect to follow.
- 3. Set the expected return and time horizon to project future value, deposits, and growth.
Formula and assumptions
The balance compounds monthly at the annual rate divided by 12 and adds the combined monthly contribution in each period.
Total deposits include the starting balance plus all modeled contributions, while growth is the amount earned above those deposits.
Notes
This does not model IRA deductibility, income phaseouts, annual contribution-limit changes, tax brackets, or conversion decisions.

FAQ
FAQ
Does this calculator apply current Traditional IRA contribution limits automatically?
No. It projects the contribution pace you enter and does not enforce IRS limits or deductibility rules.
FAQ
Should I enter a monthly figure even if I fund the IRA in lump sums?
Yes. Use the average monthly pace if you want a simple projection, or translate expected lump sums into a monthly equivalent for planning.
