Expert Guide to the Modified Adjusted Gross Income Calculator 2013
If you are looking for a reliable modified adjusted gross income calculator for 2013, the first thing to understand is that the phrase MAGI does not always mean exactly the same thing in every tax or benefits context. In retirement account rules, student loan calculations, Medicare premium rules, and Affordable Care Act coverage determinations, the starting point is often adjusted gross income, but the list of add backs can differ. The calculator on this page is built for the most common public facing use case tied to health insurance eligibility and premium assistance: 2013 ACA and Marketplace MAGI.
For that use case, the calculation is generally straightforward. You start with your adjusted gross income, then add back certain amounts that may have been excluded from taxable income. Specifically, the Affordable Care Act style MAGI formula generally includes: adjusted gross income, tax exempt interest, non taxable Social Security benefits, and foreign earned income or housing amounts excluded under federal tax rules. That is why this calculator asks for those inputs and then compares your result to the 2013 federal poverty guidelines for your household size and location.
Core 2013 ACA MAGI formula: MAGI = AGI + tax exempt interest + non taxable Social Security + excluded foreign earned income and housing.
Why the 2013 year matters
The 2013 year matters because federal poverty guidelines, tax figures, and household income records all change over time. If you are checking eligibility retroactively, reviewing prior year records, preparing documentation, or comparing a historical case, using current year thresholds would produce the wrong result. This is especially important when a family is close to important percentage bands such as 100 percent, 138 percent, 250 percent, or 400 percent of the federal poverty level.
For many ACA related determinations, your household income percentage of the federal poverty level affects whether you might qualify for Medicaid in an expansion state, cost sharing reductions, or premium tax credit ranges. Although exact rules can depend on the coverage year and state implementation, the poverty guideline benchmark remains one of the most useful ways to organize a 2013 MAGI estimate.
What counts in 2013 MAGI for health coverage purposes
- Adjusted gross income: this is your primary income base from the federal return.
- Tax exempt interest: interest that was not taxed still counts for ACA MAGI screening.
- Non taxable Social Security: only the non taxable portion is added back.
- Excluded foreign earned income or housing: excluded amounts are added back for Marketplace MAGI.
Some people are surprised that tax exempt interest and non taxable benefits are part of the formula. That is because MAGI is designed to create a broader measure of economic resources than taxable income alone. In other words, income can still affect health coverage affordability even if part of it is not taxed.
What does not automatically belong in this calculator
Not every deduction or income concept belongs in this specific version of MAGI. For example, many online calculators confuse ACA MAGI with IRA MAGI or student loan MAGI. Those versions can require different add backs, such as the student loan interest deduction, tuition and fees deduction, or excluded adoption benefits, depending on the tax rule involved. If your goal is health insurance eligibility or a premium tax credit estimate tied to 2013 income, use the ACA style formula shown above. If your goal is a Roth IRA contribution limit analysis or another tax issue, you should use a separate purpose built calculator.
2013 Federal Poverty Guidelines by Household Size
The following table uses the official 2013 federal poverty guideline amounts published by the U.S. Department of Health and Human Services. These numbers are essential because your income percentage is calculated by dividing MAGI by the guideline amount for your household size and region, then multiplying by 100.
| Household size | 48 states and DC | Alaska | Hawaii |
|---|---|---|---|
| 1 | $11,490 | $14,350 | $13,230 |
| 2 | $15,510 | $19,380 | $17,850 |
| 3 | $19,530 | $24,410 | $22,470 |
| 4 | $23,550 | $29,440 | $27,090 |
| 5 | $27,570 | $34,470 | $31,710 |
| 6 | $31,590 | $39,500 | $36,330 |
| 7 | $35,610 | $44,530 | $40,950 |
| 8 | $39,630 | $49,560 | $45,570 |
| Each additional person | +$4,020 | +$5,030 | +$4,620 |
These official values are the baseline for the calculator. If you choose a household size above eight, the script automatically extends the guideline using the published add on amount for each extra person. That makes the tool useful even for larger households that are not shown in a short table.
Important benchmark percentages
After your MAGI is calculated, the next step is understanding what the percentage means. The exact legal consequences can vary by state and year, but the following percentages are commonly used reference points in ACA discussions. The second table shows the benchmark dollar amounts for a household of four in the 48 states and DC, using the official 2013 poverty guideline of $23,550.
| Benchmark | Percent of FPL | 2013 amount for household of 4 | Why people track it |
|---|---|---|---|
| Base guideline | 100% | $23,550 | Starting point for poverty level comparison |
| Medicaid expansion reference | 138% | $32,499 | Often discussed as the adult Medicaid threshold in expansion states |
| CSR reference point | 250% | $58,875 | Common cost sharing reduction comparison point |
| Traditional premium credit ceiling reference | 400% | $94,200 | Historically important premium assistance benchmark |
How to use a modified adjusted gross income calculator for 2013
- Find your 2013 adjusted gross income from your federal return.
- Identify any tax exempt interest received in 2013.
- Determine the non taxable portion of Social Security benefits, if any.
- Add any excluded foreign earned income or housing amount.
- Select the correct household size and region.
- Click Calculate 2013 MAGI to see your total and federal poverty level percentage.
For example, assume a family of three in the 48 states had an AGI of $35,000, tax exempt interest of $500, no non taxable Social Security, and no excluded foreign income. Their MAGI would be $35,500. The 2013 poverty guideline for a household of three was $19,530. Dividing $35,500 by $19,530 gives roughly 1.818. Multiply that by 100 and the family is at about 181.8 percent of the federal poverty level.
Why the calculator also shows a chart
Visual comparisons help you quickly see whether your income falls below or above major thresholds. The chart on this page places your MAGI next to 100 percent, 138 percent, 250 percent, and 400 percent of the poverty level for your selected household size and region. This is much easier to interpret than a single income number when you are reviewing historical eligibility or planning documentation.
Common mistakes people make with 2013 MAGI
- Using gross pay instead of AGI. Your paycheck total is not the same as adjusted gross income.
- Ignoring tax exempt interest. Even though it is not taxed, it still counts for ACA MAGI.
- Adding total Social Security instead of the non taxable portion. Only the non taxable amount is added back in this formula.
- Choosing the wrong household size. Marketplace household size follows tax household concepts, not just who lives under one roof.
- Using current poverty guidelines. A 2013 review requires 2013 guideline data.
Another common issue is mixing monthly and annual figures. The calculator on this page expects annual amounts. If you only know a monthly benefit or monthly income source, convert it to a yearly total first so all figures are measured consistently.
What the result can tell you
Your result can help answer several practical questions. It can show whether a household appears to be near a poverty level benchmark, whether documentation looks internally consistent, and whether a family likely sat in a range often associated with Marketplace assistance. It can also help when you are reviewing old case files, legal records, audits, grant reports, or family financial history.
However, the result alone does not make a legal eligibility determination. Real world determinations may also involve filing status, whether a dependent was required to file, state specific implementation, immigration eligibility, reconciliation rules, and the exact coverage year tied to the application. So think of this calculator as a high quality screening and education tool rather than a substitute for official adjudication.
Best practices for documentation
- Keep a copy of the 2013 federal return and all schedules used to derive AGI.
- Retain records for municipal bond interest and any foreign income exclusions.
- If Social Security is involved, keep the annual benefits statement showing taxable and non taxable portions.
- Document the household size method you used so the poverty comparison can be replicated.

Final takeaway
A modified adjusted gross income calculator for 2013 is only useful if it uses the right formula and the right year specific poverty data. This page does both. It calculates ACA style MAGI from the inputs most relevant to health coverage screening, then translates the result into a percentage of the official 2013 federal poverty guideline for your household size and location. That combination gives you a practical and historically accurate way to analyze 2013 income.
If you are close to a threshold, double check every amount before relying on the estimate. Small changes in tax exempt interest, non taxable Social Security, or household size can move the percentage meaningfully. If the result will be used in a legal, tax, or government benefits matter, compare it against official records and guidance. For everyone else, this calculator should provide a fast, transparent, and highly usable 2013 MAGI estimate.
