When should you start a Roth IRA — and what happens if you wait?

The answer is: the first year you have earned income. The compound math makes every year of delay permanent and expensive. Here's the full picture.

Independent guidance. No financial products to sell.

There's no minimum age for a Roth IRA — only a requirement for earned income. A teenager with a summer job can contribute. A first-year employee can contribute the week they start. The question of "when to start" has one answer: as soon as you're eligible. The question worth more attention is how to prioritise it against other financial goals, and whether Roth is the right account type for your situation.


The cost of waiting

Every year you delay is expensive in a way that can't be recovered.

$7,000 contributed to a Roth IRA at age 22 grows to roughly $110,000 by age 67 at 7% annual return. The same $7,000 contributed at age 32 grows to roughly $56,000. Same contribution, same fund, same rate — but the 10-year head start nearly doubles the outcome. That gap doesn't close.
Age at contributionAmount contributedValue at 67 (7% return)Tax-free growth
22$7,000~$110,000~$103,000
25$7,000~$90,000~$83,000
30$7,000~$64,000~$57,000
35$7,000~$46,000~$39,000
40$7,000~$33,000~$26,000

These are single-year contributions. Someone who contributes $7,000/year from age 22 through 67 (45 years) accumulates roughly $3–4 million in tax-free wealth at 7%. Starting at 32 with the same annual contribution leaves roughly $2–2.5 million. The 10-year gap costs over $1 million in final balance.


The rules

Contribution limits, income limits, and the earned income requirement.

$
Contribution limit (2025): $7,000/year ($8,000 if age 50+)

You can contribute up to $7,000 per year, or your total earned income for the year if it's less than $7,000. A student earning $4,000 over the summer can contribute up to $4,000 — not $7,000. The tax year deadline for contributions is April 15 of the following year.

Earned income requirement: wages, salary, self-employment income

You must have earned income (W-2 wages, 1099 self-employment income, tip income). Investment income, rental income, and pension income don't count. Summer jobs, part-time work, and freelance all qualify. There's no minimum age — a 16-year-old with a job can open a Roth IRA (as a custodial account if under 18).

!
Income limits for direct contributions (2025)

Single: full contribution below $150,000 MAGI; phases out $150k–$165k; no direct contribution above $165k. Married filing jointly: full contribution below $236,000; phases out $236k–$246k. Above these limits: use the backdoor Roth (non-deductible traditional IRA → immediate conversion).

Spousal IRA: contribute even if one spouse doesn't work

If you're married filing jointly and one spouse has no earned income, the working spouse's income can fund a Roth IRA for the non-working spouse. Both spouses can contribute $7,000/year (up to the household's total earned income). A household earning $80,000 with one income can put $14,000/year total into Roth IRAs — one for each spouse.


Roth vs Traditional — which one?

In your 20s and most of your 30s, Roth almost always wins.

Roth IRATraditional IRA
Tax treatmentAfter-tax contributions; tax-free withdrawals in retirementPre-tax contributions (if deductible); taxed on withdrawal
Best whenCurrent tax rate is lower than expected retirement rateCurrent tax rate is higher than expected retirement rate
Required Minimum DistributionsNone during your lifetimeRMDs from age 73
Early withdrawal flexibilityContributions (not earnings) can be withdrawn tax- and penalty-free anytimeWithdrawals before 59½ trigger tax + 10% penalty
Income limitsPhase-out $150k–$165k (single, 2025)Deductibility phase-out if covered by workplace plan: $79k–$89k (single, 2025)

For most people in their 20s and early 30s, Roth is the right choice: you're likely in the 10–22% federal brackets, and retiring into a higher bracket (from RMDs, Social Security, accumulated savings) is a real possibility. Pay tax now at 12%, withdraw tax-free later instead of paying 22–24% at retirement.


The priority order

Where Roth IRA fits against your other financial goals.

1

Capture your full 401(k) employer match first

An employer match is an instant 50–100% return. Nothing — including a Roth IRA — competes with free money. Fund your 401(k) to at least the match threshold before opening a Roth IRA.

Free money — always comes first
2

Build a 3–6 month emergency fund

Roth IRA contributions (not earnings) can be withdrawn penalty-free, which gives some emergency fund flexibility — but this is not a strategy. Maintain a real emergency fund so you never need to touch retirement savings.

Foundation — prevents retirement account liquidation in a crisis
3

Max your Roth IRA: $7,000/year (2025)

After the employer match and emergency fund, this is the next dollar for most people in the 10–22% bracket. Tax-free growth for potentially 40+ years on $7,000/year of after-tax contributions is among the best wealth-building tools available.

Tax-free growth — the best long-term account for lower-bracket earners
4

Max your 401(k): $23,500/year (2025)

After the Roth IRA, go back to the 401(k) and fill it to the annual limit. Pre-tax contributions reduce your taxable income now; useful in years when income spikes or when you want to reduce current-year tax.

Pre-tax deduction — useful at higher income levels
Don't wait for the "right time" to open one

Common reasons people delay: "I'll do it when I earn more," "I want to pay off student loans first," "I'm not sure what to invest in." All of these can be addressed after opening the account. You can open a Roth IRA with $100 and invest in a target-date fund in under 20 minutes at Fidelity, Vanguard, or Schwab. The delay costs you compound growth you can never recover. Open it first, optimise later.
