How the Roth IRA Contribution Calculator Works
This calculator determines your maximum allowable Roth IRA contribution for 2025 based on your Modified Adjusted Gross Income (MAGI) and filing status. It then projects the potential tax-free growth of those contributions over your chosen time horizon.
Step 1: Determine base limit Age < 50: $7,000 / year Age ≥ 50: $8,000 / year (catch-up)
Step 2: Apply phase-out reduction If MAGI in phase-out range: Allowed = limit × (1 − phase-out %) Minimum $200 if still partially eligible
Step 3: Project future value FV = PMT × ((1+r)^n − 1) / r × (1+r)
2025 Income Phase-Out Ranges
Single / Head of Household: $150,000 – $165,000
Married Filing Jointly: $236,000 – $246,000
Married Filing Separately: $0 – $10,000
Who Should Use This Calculator?
A Roth IRA is one of the most powerful retirement accounts available to individuals under the income limits. This tool helps you figure out exactly where you stand.
Young earners
See how early contributions compound into large tax-free balances over 30–40 years.
High earners near the limit
Find out exactly how much your contribution is reduced if your income falls in the phase-out range.
Catch-up contributors
Check whether the $8,000 limit applies to you if you are 50 or older.
Dual-income households
Confirm eligibility for both spouses when combined MAGI is near the MFJ threshold.
Retirement planners
Model how a fully funded Roth IRA each year compounds alongside other retirement accounts.
Backdoor Roth candidates
Confirm you exceed the income limit before pursuing a backdoor conversion strategy.
How to Use the Calculator
1
Enter your Modified AGI
MAGI is your adjusted gross income with certain deductions added back. For most people, MAGI equals their AGI from Form 1040. If in doubt, use your W-2 income as a starting point.
2
Select your filing status
Single, Married Filing Jointly, Married Filing Separately, or Head of Household. The phase-out range differs significantly by status. Married filing separately has the tightest limit.
3
Enter your age
If you are 50 or older by December 31, 2025, you qualify for the $8,000 catch-up limit instead of $7,000.
4
Set your growth assumptions
Enter an expected annual return rate (7% is a common long-term stock market estimate) and the number of years you plan to contribute.
5
Click Calculate
The calculator shows your allowed contribution, any phase-out reduction, and a projection of your account balance assuming annual contributions at the allowed amount.
Example Calculation

Common Mistakes to Avoid
!
Contributing over the income limit
If you contribute to a Roth IRA when your income exceeds the limit, you will owe a 6% excise tax on the excess amount each year until it is corrected. Remove the excess before the tax deadline.
!
Using gross income instead of MAGI
MAGI differs from gross income. It includes certain adjustments that can push you into or out of the phase-out range. Student loan interest, IRA deductions, and rental losses all affect MAGI.
!
Missing the contribution deadline
You can contribute for the 2025 tax year until the 2025 tax filing deadline (typically April 15, 2026). Many people miss this window thinking the deadline is December 31.
!
Ignoring the 5-year rule on earnings
Roth IRA contributions can be withdrawn any time tax-free. But earnings are only tax-free after 5 years and age 59½. Opening the account early starts the 5-year clock.
!
Not using the backdoor strategy when eligible
If your income is above the limit, a backdoor Roth IRA allows you to contribute to a Traditional IRA and convert it. This strategy has no income limit on the conversion side.
Frequently Asked Questions
For 2025, you can contribute up to $7,000 to a Roth IRA if you are under 50, or $8,000 if you are 50 or older (catch-up contribution). These limits apply across all IRA accounts combined, not per account.

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.
