什么是Roth IRA Calculator？
A Roth IRA calculator projects how your retirement savings will grow over time using compound interest. By entering your current age, expected retirement age, current balance, and annual contributions, you can see your projected balance at retirement — split into contributions and tax-free growth.
The power of the Roth IRA comes from the fact that all growth is tax-free. While contributions are made with after-tax dollars, you never pay taxes on the earnings, and qualified withdrawals are tax-free in retirement. This calculator helps you visualize the long-term impact of consistent contributions and the exponential power of compound interest.
The calculator also accounts for the age 50+ catch-up contribution, allowing investors approaching retirement to contribute an extra $1,000/year to accelerate their savings.
步骤:
Enter your current age and expected retirement age.
Enter your current Roth IRA balance (or 0 if you're starting fresh).
Enter your planned annual contribution up to the $7,000 limit ($8,000 if 50+).
Enter an expected annual return — a common conservative assumption is 7%.
Toggle the age 50+ catch-up option if it applies to you.
Review your projected balance, total contributions, and tax-free growth.
公式
Monthly Growth Factor = (1 + annualRate/12)
Future Value of Contributions = Contribution × [(monthlyGrowthFactor^(months)) - 1] / (monthlyGrowthFactor - 1)
Future Value of Current Balance = CurrentBalance × monthlyGrowthFactor^(months)
Projected Balance = Future Value of Contributions + Future Value of Current Balance
Total Contributions = Annual Contribution × Years to Retirement
Total Growth = Projected Balance - Total Contributions

示例
Sarah is 30 and has $10,000 in her Roth IRA. She contributes $7,000/year and expects a 7% annual return. Over 35 years (retiring at 65): her contributions total $245,000, and with compound growth her projected balance reaches approximately $1,050,000. Her total investment growth is about $795,000 — all completely tax-free when she withdraws in retirement.
常见问题
What is a Roth IRA?
A Roth IRA is an individual retirement account where you contribute after-tax dollars. Your money grows tax-free, and qualified withdrawals in retirement are completely tax-free. This makes Roth IRAs especially powerful for young investors in low tax brackets, since you never pay taxes on the growth.
How much can I contribute to a Roth IRA in 2024-2025?
The annual contribution limit is $7,000 for 2024 and 2025. If you are age 50 or older, you can add a $1,000 catch-up contribution, bringing the total to $8,000. Contributions must be made with earned income, and there are income limits that phase out eligibility for high earners.
How much does a Roth IRA grow with compound interest?
A Roth IRA grows through the power of compound interest. With an assumed 7% average annual return, contributing $7,000/year starting at age 30 would grow to over $600,000 by age 60 — with contributions of $210,000 and growth of over $390,000. Starting early is the single biggest factor in growth.
What is the difference between a Roth IRA and a Traditional IRA?
A Traditional IRA provides a tax deduction on contributions now, but you pay income tax on withdrawals in retirement. A Roth IRA offers no upfront deduction, but withdrawals — including all growth — are tax-free in retirement. Choose Roth if you expect to be in a higher tax bracket in retirement, Traditional if you expect lower.
Can I withdraw my Roth IRA contributions before retirement?
Yes. You can withdraw your contributions (not earnings) from a Roth IRA at any time, tax-free and penalty-free, because they were made with after-tax dollars. Earnings withdrawals before age 59½ may be subject to taxes and a 10% penalty unless you meet a qualified exception.
How much should I contribute to my Roth IRA each month?
Aim to maximize your contributions up to the annual limit. If you can't afford the full $7,000, start with what you can and increase it over time — even $100/month ($1,200/year) grows substantially with 30+ years of compounding. Automated monthly contributions help maintain consistency.
At what age can I withdraw from my Roth IRA without penalty?
You can make penalty-free withdrawals of earnings at age 59½ as long as your account has been open for at least 5 years (the 5-year rule). Contributions can be withdrawn at any time. After age 72, you are not required to take minimum distributions (RMDs) from a Roth IRA, unlike Traditional IRAs.
Does a Roth IRA count as earned income?
No, a Roth IRA account itself does not count as income. However, you must have earned income (wages, salary, self-employment income) to contribute. The account's growth and withdrawals are not earned income, so they don't count toward contribution eligibility.
Can I have both a 401(k) and a Roth IRA?
Yes, you can contribute to both a 401(k) and a Roth IRA in the same year, as long as you meet the Roth IRA income limits. Many financial planners recommend contributing enough to get the full 401(k) employer match first, then maxing out your Roth IRA, and then returning to the 401(k).
What is the best age to start contributing to a Roth IRA?
The best age is as early as possible, ideally in your 20s. Because of compound interest, contributions made in your 20s are worth roughly 4-5 times more at retirement than the same contributions made in your 40s. Starting at 25 vs. 35 can mean a difference of hundreds of thousands of dollars.
Is a Roth IRA taxed on withdrawal?
No. Qualified withdrawals from a Roth IRA are completely tax-free, including all investment growth. To qualify, you must be at least 59½ years old and have held the account for at least 5 years. This is the primary advantage that makes Roth IRAs so attractive for long-term retirement savings.
