Free Roth IRA Calculator Online
Tax-free retirement growth with 2024 contribution limits, age-based projections and withdrawal income
About the Roth IRA Calculator
The Roth IRA's defining advantage is tax-free growth: you contribute after-tax dollars, but all growth and qualified withdrawals after age 59½ are completely tax-free. For someone in the 22% bracket who converts $7,000 in annual contributions into $500,000 over 35 years, the tax savings versus a traditional IRA could exceed $100,000.
The 2024 contribution limit is $7,000 per year ($8,000 if you're 50 or older), subject to income phase-out limits starting at $146,000 for single filers and $230,000 for married filing jointly. High earners above the limit can use a backdoor Roth conversion to maintain access.
Unlike Traditional IRAs, Roth IRAs have no Required Minimum Distributions (RMDs) — you can let the money grow tax-free indefinitely and pass it to heirs. This makes the Roth IRA uniquely valuable for estate planning as well as retirement income.
Starting at age 25 vs. age 35 with $7,000/year at 7% annual return produces roughly $1.37M vs. $740K at age 65 — the $70,000 in extra contributions made over the earlier decade more than doubles the final balance through compound growth.

Example Calculation
Comparing Roth IRA vs Traditional IRA net retirement value for a 30-year-old
📥 Inputs
- Age: 30 | Retirement age: 65 | Years: 35
- Annual contribution: $7,000 (2024 limit)
- Expected annual return: 7%
- Current marginal tax rate: 24% | Estimated retirement tax rate: 22%
🔢 Calculation Steps
- 1FV of $7,000/year at 7% for 35 years: $7,000 × [(1.07^35 − 1) / 0.07] = $7,000 × 138.24 = $967,676
- 2Roth IRA: withdraw full $967,676 tax-free. Net = $967,676
- 3Traditional IRA: save $7,000 pre-tax (worth $7,000/0.76 = $9,211 gross contribution equivalent). Account value same $967,676, but pay 22% tax on all withdrawals: net = $967,676 × 0.78 = $754,787
- 4Roth advantage: $967,676 − $754,787 = $212,889 more in after-tax spendable retirement income
