IRA Contribution Calculator 2026
$7,000 limit ($8,000 if 50+). Check your Roth MAGI phase-out, Traditional IRA deductibility, and Backdoor Roth option.
How to Use This Calculator
Tab "Your Limit"
Enter your age, filing status, MAGI (Modified Adjusted Gross Income), and IRA type (Roth or Traditional). The calculator checks your 2026 contribution limit against the IRS phase-out ranges. For Roth IRAs, if your income falls within the phase-out range, the calculator shows your reduced contribution amount rounded up to the nearest $10. For Traditional IRAs, anyone with earned income can contribute the full amount regardless of income.
Tab "Deductibility"
This tab determines whether your Traditional IRA contribution is tax-deductible. Enter your MAGI, filing status, and whether you or your spouse are covered by an employer retirement plan (401(k), 403(b), pension, etc.). The calculator shows how much of your contribution is deductible, the non-deductible portion, and your estimated federal tax savings based on your marginal tax rate.
Tab "Backdoor Roth"
If your income is too high for direct Roth IRA contributions, use this tab to evaluate the Backdoor Roth strategy. Enter your existing Traditional IRA balance and the amount you plan to convert. The calculator checks the pro-rata rule: if you have pre-tax money in any Traditional, SEP, or SIMPLE IRA, a proportional share of your conversion will be taxable. If your existing balance is zero, the conversion is tax-free.
The Formulas
Reduced limit = Base limit × (Upper threshold − MAGI) ÷ (Upper threshold − Lower threshold)
Round up to nearest $10
Single/HoH: $150,000–$165,000 · MFJ: $236,000–$246,000
Below lower threshold = full contribution · Above upper threshold = $0
Traditional IRA Deductibility Phase-Out:
If covered by employer plan: Single $79K–$89K · MFJ $126K–$146K
If not covered but spouse is (MFJ): $236K–$246K
Neither covered: fully deductible at any income
Pro-Rata Rule (Backdoor Roth):
Taxable portion = Conversion amount × (Pre-tax IRA balance ÷ Total IRA balance)
Total IRA balance = Pre-tax balance + Non-deductible contribution
All Traditional, SEP, and SIMPLE IRA balances are aggregated as of December 31
Example
$155,000 MAGI — Single, Age 40, Roth IRA
At $155K MAGI as a single filer, your Roth IRA contribution is reduced from $7,000 to $4,670. If you want to get the full $7,000 into a Roth IRA, consider the Backdoor Roth strategy: contribute $7,000 to a non-deductible Traditional IRA and then convert to Roth. If you have no existing pre-tax IRA balance, the conversion is tax-free.
