Question 1

What is a Roth IRA calculator?

Accepted Answer

A Roth IRA calculator projects how much your retirement account will be worth when you stop working. You enter your current age, retirement age, annual contribution, existing balance, and expected return rate. The calculator compounds that growth annually and shows your total tax-free balance at retirement — the amount you can withdraw without owing any federal income tax.

Question 2

How much can I contribute to a Roth IRA in 2024?

Accepted Answer

The 2024 Roth IRA contribution limit is $7,000 per year if you are under age 50, and $8,000 if you are age 50 or older (the extra $1,000 is called the catch-up contribution). These limits apply per person, not per account. You cannot contribute more than your earned income for the year, and your ability to contribute phases out at higher income levels.

Question 3

What are the Roth IRA income limits for 2024?

Accepted Answer

For 2024, single filers begin to phase out at $146,000 MAGI and cannot contribute at all above $161,000. Married filing jointly begins phasing out at $230,000 and cuts off at $240,000. Married filing separately phases out from $0 to $10,000. This calculator flags a warning if your income falls in the phase-out range but does not block your projection — you may still be eligible for a partial contribution or a backdoor Roth.

Question 4

What return rate should I use for a Roth IRA projection?

Accepted Answer

For a stock-heavy Roth IRA invested in broad index funds, 7% annual return is a reasonable real-terms estimate (S&P 500 historical average is ~10.7% nominal, minus ~3% inflation = ~7.5% real). The default in this calculator is 7%. Conservative planners use 5–6%. Do not use nominal returns for long-horizon retirement planning without accounting for inflation — it significantly overstates purchasing power.

Question 5

Does this calculator account for taxes on withdrawals?

Accepted Answer

No taxes are deducted from Roth IRA withdrawals in this calculator — because qualified Roth IRA withdrawals are genuinely tax-free. You pay income tax on contributions now (they are post-tax dollars), but all growth and all qualified withdrawals after age 59½ are 100% federal-tax-free. This is the core advantage of a Roth IRA over a Traditional IRA or 401(k), where withdrawals are taxed as ordinary income.

Question 6

What is the difference between a Roth IRA and a Traditional IRA?

Accepted Answer

The key difference is when you pay taxes. Traditional IRA: you deduct contributions now (tax break today), but pay income tax on all withdrawals in retirement. Roth IRA: you get no deduction now, but all growth and withdrawals in retirement are tax-free. If you expect to be in a higher tax bracket in retirement than you are today, Roth usually wins. Roth IRAs also have no Required Minimum Distributions (RMDs), giving more control over when you withdraw.
