Roth IRA Calculator

Estimate your potential Roth IRA balance at retirement by modeling contributions, growth, and tax-free withdrawals.

Quick answer: A Roth IRA grows after-tax money for tax-free qualified withdrawals. Contribution eligibility depends on income limits, and the long-term value depends on contributions, return, time, and tax assumptions.

Diagnostic

Contributing $7,500 per year for 25 years could grow to $662,292; qualified Roth IRA withdrawals may be federal income-tax-free.

At an illustrative 24.00% tax rate, the projected investment growth represents $107,950 of potential tax exposure outside a tax-advantaged account. This is not a Roth-versus-traditional comparison.

Frequently Asked Questions

Everything you need to know.

What does an example Roth IRA Calculator calculation look like?
Using this calculator's own default assumptions, a annual contribution of $7,500, current balance of $25,000 and years to retirement of 25 produces an estimated projected roth ira balance of $662,292 and total contributions of $212,500. Enter your own numbers above to see how it changes for your situation.
Why does the projected balance include investment growth beyond my contributions?
Your contributions earn returns each year, and those returns earn returns themselves. This compounding effect accelerates over longer time horizons. The calculator shows how much of your final balance comes from your own money versus earnings, so you can see the power of time in the market.
What does the illustrative tax calculation show?
It displays what you would owe in taxes on your growth if it were taxed at a standard rate, helping you visualize the tax advantage of a Roth IRA. Since Roth withdrawals are tax-free in retirement, this illustrates the actual benefit you're gaining by using this account type instead of a taxable investment account.
Is the Roth IRA Calculator free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the Roth IRA Calculator affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.

Understanding your projected balance helps you gauge whether your current contribution strategy aligns with your retirement income goals. The longer your money compounds, the more growth potential you unlock, making early and consistent contributions powerful over time.
