How it works
A Roth IRA is funded with after-tax money, so contributions aren't deductible — but the balance grows tax-free and qualified withdrawals in retirement are completely tax-free. It's powerful if you expect to be in the same or a higher tax bracket later.
Tax-free growth
FV = PV(1 + r)ⁿ + PMT · [(1 + r)ⁿ − 1] / r (withdrawals tax-free)
- PMT
- annual contribution (2026 limit $7,500; $8,600 if 50+)
- r
- expected return
- n
- years to retirement
Worked example
- Contribute $7,500/year at 7%
- Over 30 years
- FV = 7,500 × [(1.07³⁰ − 1) / 0.07]
≈ $708,000 — and none of it is taxed on withdrawal.
Good to know
- You can withdraw your contributions (not earnings) anytime tax- and penalty-free.
- There's no required minimum distribution, so a Roth can grow untouched for life.
- High earners may exceed the income limit to contribute directly (a backdoor Roth is the workaround).

Frequently Asked Questions
How much can I contribute to a Roth IRA in 2026?
The 2026 IRA contribution limit is $7,500, or $8,600 if you're 50 or older. Direct Roth contributions phase out at higher incomes, and you need earned income at least equal to your contribution.
What is the difference between a Roth IRA and a traditional IRA?
Roth contributions are made with after-tax money, then grow and come out tax-free in retirement; traditional contributions may be deductible now but withdrawals are taxed. Roth tends to win if you expect your tax rate to be the same or higher later.
Can I withdraw money from a Roth IRA early?
You can withdraw your contributions (not earnings) at any time, tax- and penalty-free. Earnings come out tax-free only after age 59½ and once the account has been open five years.
Does a Roth IRA have required minimum distributions?
No — Roth IRAs have no RMDs during your lifetime, so the balance can compound untouched indefinitely. That also makes them a popular vehicle for leaving tax-free money to heirs.
What if I earn too much to contribute directly?
High earners often use a backdoor Roth: contribute to a nondeductible traditional IRA, then convert it to Roth. Watch the pro-rata rule if you hold other pre-tax IRA balances, as it can make part of the conversion taxable.
