How the calculation works
Projects entered contributions and applies the entered retirement tax rate; the default contribution is the 2026 IRA limit.
Worked example
In the IRA worked example, current balance $25,000, annual before tax contribution $7,500, expected rate of return 7 %, current age 35 years produces balance at age 65 of $898,762.27. Tax-deferred balance: $898,762.27. Review the displayed units before comparing the result.
Understanding the result
The IRA reports balance at age 65. Use it as a planning baseline, then compare the estimate with current rates, fees, taxes, and provider terms. U.S. retirement-planning estimate only. Compensation eligibility, combined IRA limits, deduction or Roth phaseouts, excess contributions, tax treatment, and future law can change the result.
How to check the answer
Check the IRA result by entering the same current balance, annual before tax contribution, expected rate of return in an independent statement, lender, provider, or official tool. Change one input and confirm that balance at age 65 moves in the direction implied by Projects entered contributions and applies the entered retirement tax rate; the default contribution is the 2026 IRA limit.
