How it works
traditional vs roth ira calculator takes your inputs and produces traditional ira value, roth ira value, traditional after-tax. Compare Traditional vs Roth IRA tax benefits based on your current and retirement tax rates. You provide 5 inputs: Current Tax Rate % (percent, in percent) (default: 24 percent); Retirement Tax Rate % (percent, in percent) (default: 12 percent); Annual Contribution (currency, in dollars) (default: 6500 dollars); Years to Retirement (number) (default: 30); Investment Return % (percent, in percent) (default: 7 percent). The calculator returns 3 outputs: Traditional IRA Value (the primary result); Roth IRA Value (a secondary output); Traditional After-Tax (a secondary output). Investment calculations rest on a few variables — principal, return rate, time, and compounding — but their interaction is non-linear enough that intuition alone gets the answer wrong more often than not. This tool runs the real formula with your inputs and shows the numbers that matter, not the rounded approximations from a textbook. With the default values, traditional ira value is computed from the interaction of every input field — change any one of them and the result updates immediately, so you can stress-test different scenarios without re-entering the whole form. Adjust the inputs to match your real financial situation. The defaults are realistic starting points, but every person's circumstances differ — your actual income, expenses, rates, and timelines will produce a different answer. Use the tool iteratively: start with the defaults, then change one variable at a time to see which factor has the largest impact on your outcome.Tips
- Start with the default values to see a baseline result, then change one input at a time to understand which factor matters most for your outcome.
- Replace every default with your actual number — estimates and rules of thumb produce estimates, not answers. Pull your real figures from pay stubs, statements, or account dashboards.
- Use a conservative return rate (5-6% rather than the historical 10%) for planning purposes. Markets have long flat stretches, and planning on the average sets you up for a shortfall.
