Roth vs. Traditional — after-tax value at retirement
How it's calculated
FV = B(1+r)ⁿ + C × [ ((1+r)ⁿ − 1) / r ]
B = current balance ·
C = annual contribution ·
r = expected annual return ·
n = years to retirement
Roth after-tax value = FV — qualified withdrawals are tax-free.
Traditional after-tax value ≈ FV × (1 − marginal tax bracket at withdrawal).
Roth after-tax value = FV — qualified withdrawals are tax-free.
Traditional after-tax value ≈ FV × (1 − marginal tax bracket at withdrawal).
Key concepts
The terms behind the numbers above, explained simply.
Definition
A Roth IRA is funded with after-tax money — you pay tax now, and qualified withdrawals in retirement are completely tax-free, including all the growth. A Traditional IRA is funded pre-tax (often tax-deductible now), but withdrawals in retirement are taxed as ordinary income.
Definition
The IRS caps how much you can contribute to an IRA each year, with a higher limit for those age 50+ ("catch-up contributions"). These limits change periodically — always confirm the current year's limit at irs.gov before relying on this number for real planning.
Definition
Inside a Roth IRA, investment growth (dividends, interest, capital gains) is never taxed as long as withdrawal rules are followed — unlike a regular brokerage account, where growth can trigger taxes along the way.
Definition
A Roth IRA withdrawal that's 100% tax- and penalty-free. Generally requires the account to be open 5+ years and the account holder to be 59½ or older (some exceptions apply for first-time home purchase, disability, etc.).
Definition
Roth IRA eligibility phases out at higher incomes, based on Modified Adjusted Gross Income (MAGI). Above certain thresholds (which change yearly and vary by filing status), your allowed contribution shrinks or disappears — this calculator doesn't check income eligibility, so confirm you qualify before contributing.
Not financial advice. Finistack calculators are educational tools that estimate outcomes based on the assumptions you enter. They're not financial, tax, or legal advice, and Finistack is not a bank, CPA, or certified financial adviser. This tool doesn't check IRS contribution limits, income eligibility (MAGI phase-outs), or your specific tax situation — verify current rules at irs.gov or with a tax professional before contributing.
