How to Calculate Your Roth IRA Contribution Limit
Your 2025 Roth IRA contribution limit depends on your MAGI and filing status. Use the 401k Calculator with Match alongside this tool if you contribute to both accounts. The IRS phase-out formula works in four steps:
If MAGI ≤ range_base: phase_pct = 0 (full limit applies)
If MAGI ≥ range_top: contribution = $0
Step 3: Apply reduction
reduced = base_limit x (1 - phase_pct)
Round down to nearest $10; min $200 if partially eligible
Step 4: Project future value (annuity due)
FV = PMT x ((1+r)^n - 1) / r x (1+r)

Roth IRA Contribution Limits 2026
For 2026, the Roth IRA contribution limits remain $7,000 per year for those under 50 and $8,000 for those 50 and older. The base limits have not changed since 2024. The IRS adjusts phase-out thresholds annually using COLA calculations, but adjustments are made in $1,000 increments and only trigger when inflation crosses the rounding threshold.

Backdoor Roth IRA Contribution Limits 2025
The backdoor Roth IRA is a two-step process for high earners who exceed the direct contribution income limits. The Dividend DRIP Calculator can model how tax-free compounding affects reinvested dividend growth over the same timeline.
Step 1: Contribute to a non-deductible traditional IRA
Limit: $7,000 (under 50) or $8,000 (50+)
No income limit on this step
Step 2: Convert the traditional IRA to Roth
No income limit on the Roth conversion
Tax owed = converted amount x ordinary income rate
(non-deductible basis is not taxed again)
The Pro-Rata Rule
If you have pre-tax IRA balances (rollover IRAs, SEP IRAs, SIMPLE IRAs), the IRS treats all IRAs as one pool when calculating the taxable share of your conversion. The taxable fraction equals pre-tax IRA assets divided by total IRA assets.
Example: $94,000 pre-tax rollover IRA + $7,000 new non-deductible contribution = $101,000 total. Pre-tax fraction: 94/101 = 93.1%. Converting $7,000 makes $6,517 taxable even though you contributed after-tax. To sidestep the pro-rata rule, roll the pre-tax IRA into a 401k if your plan accepts incoming rollovers.
Roth IRA Contribution Deadline 2025
The Roth IRA contribution deadline matches the federal tax filing deadline, not December 31. This gives you more than 15 months from January 1 of the tax year to fund the prior-year account.

Example Calculation
Suppose you are 35 years old, single, with a MAGI of $152,000. Your income is in the phase-out range. You plan to invest at 7% for 30 years. See the Coast FIRE Calculator to model when a partially funded Roth IRA can grow to your target without additional contributions.

Common Mistakes to Avoid
Contributing over the income limit
If you contribute when your MAGI exceeds the top of the phase-out range, you owe a 6% excise tax on the excess each year until corrected. Remove the excess before the tax deadline or recharacterize it as a traditional IRA contribution.
Using gross income instead of MAGI
MAGI differs from gross income. Pre-tax 401k contributions, student loan interest deductions, and rental losses can all reduce MAGI below your gross pay. Always calculate MAGI before checking eligibility.
Missing the contribution deadline
The 2025 Roth IRA contribution deadline is April 15, 2026, not December 31, 2025. Many people miss prior-year contributions because they assume the window closes at year-end.
Ignoring the 5-year rule on earnings
Roth IRA contributions can be withdrawn any time without penalty. But earnings are only tax-free after 5 years from account opening and after age 59 and a half. Open the account early to start the clock.
Skipping the backdoor strategy when income exceeds limits
If your MAGI exceeds the top of the phase-out range, a backdoor Roth IRA lets you contribute to a non-deductible traditional IRA and convert it. The contribution step has the same $7,000/$8,000 limit; the conversion has no income limit.
Frequently Asked Questions
The 2025 Roth IRA contribution limit is $7,000 per year for those under 50, or $8,000 for age 50 and older (the $1,000 catch-up contribution). These limits apply across all traditional and Roth IRA accounts combined. The limit phases out for single filers with MAGI between $150,000 and $165,000, for married filing jointly between $236,000 and $246,000, and for married filing separately between $0 and $10,000.

Pro Tip
Open a Roth IRA even in years when you can only contribute a small amount. The 5-year rule clock starts when you open the account, not when you make your first large contribution. A $1 contribution today starts the clock.
