Why this result matters

What this calculator helps you answer

A Roth IRA growth calculator focused on annual contribution caps, catch-up treatment, and tax-free retirement value over time. Use the tool above to enter a few clear inputs and get a practical answer you can use right away.

This Roth IRA calculator estimates long-run tax-free growth from a current balance, annual contributions, and expected return. It applies simple annual contribution-cap guardrails so users can compare retirement scenarios while keeping the page distinct from 401(k), traditional IRA, and broader retirement-planning calculators.

Formula and method

How the calculation works

The calculator compounds the current Roth IRA balance monthly and adds eligible annual contributions up to the current cap over the years remaining until retirement.

Example

Example Roth IRA projection

If current age is 35, retirement age is 65, the starting balance is 25,000, annual contribution is 7,000, and expected annual return is 7%, the calculator estimates long-run Roth IRA growth and tax-free value at retirement.

FAQ

Common questions about this calculator.

Short answers to the questions people often ask before or after using the tool.

Question

Does this calculator check Roth IRA income eligibility?

No. It models contribution caps and growth only, and does not include income phaseouts or backdoor Roth strategies.

Question

How are contribution caps handled?

The calculator applies a simple current annual contribution cap based on the starting age you enter, including catch-up treatment for savers age 50 and older.

Question

How is this different from a 401(k) calculator?

A Roth IRA focuses on after-tax contributions and tax-free qualified withdrawals, while a 401(k) calculator is usually centered on salary deferrals, employer match, and workplace-plan limits.
