What’s the main difference from a Traditional IRA?

Roth contributions are made after-tax with (generally) tax-free qualified withdrawals in retirement; Traditional contributions are often pre-tax with withdrawals taxed as ordinary income later. This calculator projects the same growth math for both — the difference is in how the money is taxed, not the growth formula.

Does this account for contribution limits?

No — IRS contribution limits change annually and depend on your age and income; check the current limit before assuming you can contribute the amount you enter.

Years until retirement

Roth IRA contributions are made with after-tax money — you don't get a tax deduction now, but qualified withdrawals in retirement (including all this growth) are typically tax-free. Contribution limits are set annually by the IRS; check the current limit before assuming you can contribute this much.
