Variables: Contribution: The annual amount saved into the IRA. Current Tax Rate: The marginal income tax rate applied to current income. Growth Rate: The assumed annual investment return. Years: The number of years until retirement. Future Tax Rate: The assumed marginal income tax rate during retirement.
Worked Example: Assume a 35-year-old earning $90,000 contributes $7,000 annually for 30 years with a 7% growth rate. If their current tax rate is 22% and their retirement tax rate is 15%, then a Traditional IRA would offer upfront tax deductions, while a Roth IRA would provide tax-free withdrawals in retirement. The calculator would show the projected after-tax balance for each at age 65.
This calculator's methodology aligns with IRS guidelines for IRA contribution limits and tax treatment. It applies standard financial principles of compound interest to project investment growth. The calculations are based on the tax laws and regulations published by the Internal Revenue Service.

How This IRA Calculator Works - Tax Methodology
Our IRA Calculator System uses advanced tax algorithms with IRS-compliant income limit analysis to provide accurate Traditional vs Roth IRA comparisons. Here's the complete technical methodology:
Core Financial Engine: Uses future value calculations with tax optimization for precise IRA projections.
Traditional IRA Formula: After-Tax Value = [P(1+r)^t + C×((1+r)^t-1)/r] × (1 - Retirement Tax Rate)
Roth IRA Formula: After-Tax Value = P(1+r)^t + C×((1+r)^t-1)/r (already taxed upfront)
Income Limit Analysis: Automatically adjusts for 2026 IRS limits:
- Traditional IRA deduction phase-out: $77,000-$87,000 (single with workplace plan)
- Roth IRA contribution phase-out: $146,000-$161,000 (single)
- Backdoor Roth IRA calculations for incomes above limits
Tax Optimization Variables:
- P: Initial investment (after tax for Roth, before tax for Traditional)
- C: Annual contribution amount
- r: Annual investment return rate
- t: Years until retirement
- Current Tax Rate: Marginal tax rate during contribution years
- Retirement Tax Rate: Expected marginal tax rate during withdrawal years
$90,000 Income Optimization: Specifically calibrated for middle-income earners with detailed phase-out analysis and tax bracket considerations.
Backdoor Roth Modeling: Includes calculations for high-income earners who exceed direct contribution limits.
Visualization Engine: Using Chart.js for interactive Traditional vs Roth comparison visualization.
IRA Strategy Recommendations
