Formula & methodology

Formula: FV = sum of each year's contribution x (1 + r)^(years remaining)

The Roth IRA Calculator is built on a well-established calculation method.

A Roth IRA is funded with after-tax dollars, so qualified growth and withdrawals are completely tax-free. The calculator compounds each annual contribution to retirement age at your assumed return. Because no tax is owed on the back end, a Roth is especially valuable if you expect to be in a similar or higher tax bracket later, or want decades of untaxed compounding.

How to use the Roth IRA Calculator

Enter your current balance, how much you contribute annually (up to the annual contribution limit), your expected annual return, and the years until retirement. The tool projects the balance with FV = sum of each year's contribution × (1 + r)^(years remaining), compounding both your existing balance and each new contribution. Because Roth withdrawals are tax-free in retirement, the projected figure is your real future spending power — no tax discount needed.

Interpreting your result

The Roth's power is that every dollar of growth is tax-free at withdrawal, unlike a traditional 401(k) or IRA where distributions are taxed as income. The calculator's breakdown — contributions versus growth — shows how much of the final balance is tax-free earnings: at 7% over 30 years, growth typically dwarfs the contributions you made. The trade-off is that Roth contributions use after-tax dollars now, so the decision between Roth and traditional depends on whether you expect to be in a higher tax bracket in retirement. The tool is also useful for tracking how close you are to the contribution limits and what skipping a year's contribution costs in lost compounding.

Common mistakes to avoid

The most common error is ignoring the contribution limits and income phase-outs, which change over time and cap who can contribute directly. Second, assuming the Roth is always better — for someone in a low bracket now who expects a lower bracket in retirement, the traditional account can win despite the tax on withdrawals. Third, withdrawing earnings before age 59½, which triggers taxes and penalties on the growth portion. Finally, forgetting that the contribution itself is capped each year — maxing out early in the year gives the money more time to compound.

Tips for best results

Contribute as early in the year as possible — money in the market longer compounds more. Max the contribution before considering a brokerage account, because the tax-free wrapper is the scarce resource. Use the calculator to compare Roth vs traditional by modeling the tax rates at each end. If your income exceeds the Roth limit, use the backdoor Roth strategy. Review the projection annually and increase contributions with raises — the contribution limit rises over time and the extra years of compounding matter.

Frequently asked questions

What is the 2026 Roth IRA contribution limit?

The Roth IRA Calculator is free, private, and accurate: it runs entirely in your browser (no uploads, no accounts), applies the standard calculation, and explains each step so you can verify the result. Estimates the tax-free growth of a Roth IRA. Enter your current balance, planned annual contributions, expected annual return, and years until retirement, and the tool projects your future account value — all of which you can withdraw tax-free in retirement. There is no limit on usage, and it works on any device.

Are Roth IRA withdrawals taxed?

Qualified withdrawals are entirely tax-free: contributions were made with after-tax dollars, and earnings are tax-free if the account is at least 5 years old and you are 59½ or meet an exception. This is the Roth's core advantage — no tax on the growth. Non-qualified withdrawals of earnings are taxed and penalized, so the 5-year and age rules matter.

Can high earners contribute to a Roth IRA?

Direct contributions phase out at higher incomes (2026: roughly $150K–$165K for single filers and $236K–$246K for married filing jointly, adjusted annually). High earners can still use the backdoor Roth: contribute to a traditional IRA, then convert to a Roth. There is no income limit on conversions, though tax applies to any pre-tax amount converted.

Roth IRA vs traditional IRA — which is better?

The choice hinges on your tax rate now versus in retirement. Roth wins if you expect to be in a higher bracket later (early-career earners), because you pay tax now at the lower rate. Traditional wins if your retirement rate will be lower, since contributions are deductible now. If you cannot predict, splitting contributions is a reasonable hedge. The calculator projects the Roth side of the decision.

Can I withdraw my Roth contributions early?

Yes — contributions can be withdrawn anytime tax- and penalty-free, because they were already taxed; only the EARNINGS are restricted until age 59½ and the 5-year rule. This makes the Roth a flexible emergency fund as a last resort, though withdrawing contributions forfeits their future growth. The calculator models the growth you would lose by withdrawing early.
