Aotc Calculator
The American Opportunity Tax Credit is the most generous education tax break in the code: up to $2,500 per eligible student per year, with up to $1,000 of it refundable even if you owe no tax. The catch is the phaseout. A single filer at $85,000 of MAGI loses half the credit, and at $90,000 it is gone entirely.
The AOTC Calculator below applies the real formula: 100% of the first $2,000 of qualified expenses plus 25% of the next $2,000, then the income phaseout for your filing status, then the split between the refundable and nonrefundable portions. It also runs the three eligibility gates first, so a student who fails one does not get a phantom credit number.

Quick Answer
Key takeaways
- Formula: 100% of the first $2,000 plus 25% of the next $2,000; the max is $2,500 per student.
- 40% of the credit is refundable, capped at $1,000, even with zero tax liability.
- Full credit to $80k single / $160k joint MAGI; gone at $90k / $180k.
- First 4 years only, half-time enrollment, degree program, no felony drug conviction.
How the AOTC is actually calculated
Two formulas in sequence. First the expense formula: dollar-for-dollar on the first $2,000 of adjusted qualified expenses, then 25 cents on each of the next $2,000. Spend $4,000 or more on qualifying costs and you hit the $2,500 ceiling. Second the phaseout: if your MAGI sits inside the range, you lose a fraction of the credit equal to (MAGI – lower threshold) / $10,000 single or / $20,000 joint.
The phaseout thresholds are statutory and have not been inflation-adjusted since the credit became permanent, which quietly makes the credit harder to keep each year. Your MAGI for this purpose is generally just your AGI from Form 1040; only foreign earned income exclusions and a few territorial exclusions get added back.
Worked example, checked against this exact tool
With the pre-filled defaults ($4,000 expenses, single, $85,000 MAGI, all gates passed), the calculator returns:
| Figure | Amount |
|---|---|
| Tentative credit | $2,500.00 |
| Phaseout reduction (50%) | $1,250.00 |
| Allowed credit | $1,250.00 |
| Refundable portion | $500.00 |
| Nonrefundable portion | $750.00 |
By hand: (85,000 – 80,000) / 10,000 = 0.50, so half the $2,500 tentative credit survives. Forty percent of $1,250 is $500 refundable. If the same filer had $3,000 of expenses instead, the tentative credit would be $2,000 + 0.25 x $1,000 = $2,250, and the allowed credit $1,125. Try both in the tool; they match.
The 2026 phaseout thresholds
| Filing status | Full credit | Phaseout range | No credit |
|---|---|---|---|
| Single / head of household | Up to $80,000 MAGI | $80,000 – $90,000 | Above $90,000 |
| Married filing jointly | Up to $160,000 MAGI | $160,000 – $180,000 | Above $180,000 |
| Married filing separately | Ineligible at any income | ||
Halfway through the single range ($85,000) loses half the credit; halfway through the joint range ($170,000) loses half as well. The denominator doubles for joint filers, so the phaseout is gentler per dollar of MAGI.
AOTC vs Lifetime Learning Credit
American Opportunity Credit
- Max $2,500 per student per year
- 40% refundable (up to $1,000)
- First 4 years of undergraduate only
- Half-time enrollment, degree program required
- Felony drug conviction disqualifies
Lifetime Learning Credit
- Max $2,000 per tax return (not per student)
- Not refundable at all
- Any year, including graduate school
- One course is enough; no degree required
- No drug-conviction rule
The general rule: if the student is in years 1-4 and eligible, take the AOTC. It pays more and part of it is refundable. After year 4, or for graduate students and skill courses, the Lifetime Learning Credit is the remaining option. You cannot claim both for the same student in the same tax year.
What competing calculators miss
The gates come first. Most AOTC tools jump straight to the expense formula and hand you $2,500 for a graduate student or a married-filing-separately return, both ineligible. The three eligibility gates above are checked before any math runs, so ineligible inputs get a plain explanation instead of a phantom number.
The refund split is the point. Calculators that show only the total credit hide the feature that makes the AOTC special: the 40% refundable portion. For a student with little or no tax liability, the refundable $1,000 is the entire value. This tool breaks it out on every result.
Adjusted expenses, not the tuition bill. The credit runs on qualified expenses after subtracting tax-free scholarships, grants, and refunds. Plugging the sticker tuition number into a calculator overstates the credit whenever aid covered part of the bill.
Per-student vs per-return. The AOTC ceiling is per eligible student; a family with two qualifying students can claim up to $5,000. The Lifetime Learning Credit ceiling is per return. Tools that blur this cost multi-student families real money on paper.
Frequently asked questions
Tuition, required enrollment fees, and required books, supplies, and equipment. Subtract tax-free scholarships, grants, Pell grants, employer aid, veterans benefits, and any refunds first. Room and board, transportation, insurance, and medical costs do not qualify, and you cannot use the same expenses for another education credit or tax-free benefit.
Partially. Forty percent of the credit is refundable, up to $1,000, so you can get money back even with zero tax liability. The remaining 60% is nonrefundable: it can reduce your tax bill to zero but generates no additional refund.
Full credit up to $80,000 MAGI for single filers ($160,000 joint), phasing out to zero at $90,000 ($180,000 joint). Married filing separately filers cannot claim the credit at all. The thresholds are set by statute and have not moved with inflation.
Four tax years per student, and only during the first four years of post-secondary education. Once the four years are used, or the student moves to graduate school, the Lifetime Learning Credit becomes the option.
Not for the same student in the same year. You can claim the AOTC for one student and the LLC for a different student on the same return, but never both credits on the same student’s expenses.
No. The AOTC is limited to the first four years of post-secondary education. Graduate students, and anyone past year four, should look at the Lifetime Learning Credit, which covers graduate and professional courses with no year limit.
You lose a fraction of the credit: (MAGI minus the lower threshold) divided by $10,000 for single filers or $20,000 for joint filers. At $85,000 single, you keep half. Small MAGI changes near the edges move the credit noticeably, so use your exact figure.
