How Do You Calculate Federal Poverty Level

Use this premium Federal Poverty Level calculator to estimate your household’s poverty guideline amount and your income as a percentage of the federal poverty level based on household size, location, and income period.

Expert Guide: How Do You Calculate Federal Poverty Level?

The federal poverty level, often shortened to FPL, is a government benchmark used to measure household income against a national poverty guideline. If you have ever applied for Medicaid, CHIP, premium tax credits through the Health Insurance Marketplace, hospital financial assistance, or other means-tested programs, you have likely seen income expressed as a percentage of the federal poverty level. Understanding how to calculate it is useful because eligibility rules for many public and private assistance programs are based on whether your household income falls below 100%, 138%, 150%, 200%, 250%, or 400% of FPL.

At its core, the calculation is simple. You first determine the correct poverty guideline for your household size and geographic area. Then you compare your household income to that poverty guideline. The result tells you your income as a percentage of FPL. The reason the process sometimes feels confusing is that there are different household counting rules, different annual income methods, and separate poverty guideline schedules for the 48 contiguous states and Washington, DC, Alaska, and Hawaii.

The basic formula

The standard formula for calculating FPL percentage is:

1. Find the annual federal poverty guideline for your household size and location.
2. Convert your household income to an annual amount if it is monthly, weekly, or biweekly.
3. Divide your annual household income by the annual poverty guideline.
4. Multiply the result by 100.

Written as a formula, it looks like this: (annual household income / annual poverty guideline) x 100 = percentage of FPL.

For example, suppose a family of four in the 48 contiguous states has annual income of $45,000. Using the 2024 HHS poverty guideline, the poverty guideline for a family of four is $31,200. Divide $45,000 by $31,200 to get about 1.4423. Multiply by 100 and the household is at about 144.2% of FPL.

2024 federal poverty guideline amounts

The U.S. Department of Health and Human Services publishes annual poverty guidelines. These are not the same as the Census Bureau poverty thresholds, although they are related. For benefit eligibility, many programs rely on the HHS poverty guidelines. Below is a practical snapshot of the 2024 guideline levels for common household sizes.

Household Size	48 States and DC	Alaska	Hawaii
1	$15,060	$18,810	$17,310
2	$20,440	$25,540	$23,500
3	$25,820	$32,270	$29,690
4	$31,200	$39,000	$35,880
5	$36,580	$45,730	$42,070
6	$41,960	$52,460	$48,260
7	$47,340	$59,190	$54,450
8	$52,720	$65,920	$60,640

For households larger than eight, HHS says to add a set amount for each additional person. In 2024, that add-on is $5,380 for each extra person in the 48 states and DC, $6,730 for each extra person in Alaska, and $6,190 for each extra person in Hawaii.

How to annualize your income before calculating FPL

Many people do not know their income in one annual number. They may know what they earn each week, every two weeks, or each month. To calculate FPL accurately, you should convert that amount into annual income first.

• Weekly income: multiply by 52
• Biweekly income: multiply by 26
• Monthly income: multiply by 12
• Annual income: use the amount directly

If a household earns $3,200 per month, annual income is $38,400. If the same household size and region has a poverty guideline of $31,200, then $38,400 / $31,200 x 100 = 123.1% of FPL.

Who counts in your household?

This is one of the most important parts of the process. The correct household size can change the poverty guideline significantly. Depending on the program, household may mean tax household, Medicaid household, or people who live together and share resources. In many common situations, household size includes you, your spouse if applicable, and dependents you claim or expect to claim on your tax return. However, some programs use separate rules for children, pregnant individuals, non-filers, or blended households.

Because household counting rules vary by program, you should always confirm the precise definition for the benefit you are applying for. For Marketplace savings, modified adjusted gross income and tax household rules usually apply. For Medicaid, the rules are often similar but can differ depending on the applicant’s filing status and state implementation.

Common FPL thresholds used in eligibility screening

Many assistance programs do not simply ask whether you are below 100% of poverty. Instead, they use a multiple of the poverty guideline. Here are several common reference points:

FPL Threshold	What It Often Relates To	Example for Household of 4 in 48 States and DC
100% FPL	Baseline federal poverty guideline	$31,200
138% FPL	Common Medicaid expansion benchmark for adults in expansion states	$43,056
150% FPL	Used in some subsidy and assistance screening contexts	$46,800
200% FPL	Frequently used in hospital charity care and state program screening	$62,400
250% FPL	Common benchmark in supplemental aid rules	$78,000
400% FPL	Historically important in ACA subsidy discussions	$124,800

Step-by-step example calculations

Let us walk through several examples so you can see how the math works in real life.

1. Single adult in the 48 states and DC: Income is $24,000 per year. Household size is 1. The 2024 poverty guideline is $15,060. Calculation: $24,000 / $15,060 x 100 = 159.4% of FPL.
2. Married couple in Hawaii: Income is $4,000 per month. Household size is 2. Annual income is $48,000. Hawaii guideline for 2 is $23,500. Calculation: $48,000 / $23,500 x 100 = 204.3% of FPL.
3. Family of five in Alaska: Income is $1,500 per week. Annual income is $78,000. Alaska guideline for 5 is $45,730. Calculation: $78,000 / $45,730 x 100 = 170.6% of FPL.

These examples show why FPL is more useful than looking at a raw salary by itself. A $40,000 income may be far above poverty for one person but much closer to poverty for a larger family. The household-size adjustment is what makes FPL so important in public policy.

Why Alaska and Hawaii have different poverty guidelines

Alaska and Hawaii have separate guideline amounts because the federal government recognizes that costs and economic conditions differ from those in the 48 contiguous states and Washington, DC. While the poverty guideline is still a simplified national tool and not a full cost-of-living index, these separate schedules try to better reflect the higher costs commonly associated with those states.

Federal poverty guidelines versus Census poverty thresholds

People often confuse these terms. The Census Bureau poverty thresholds are primarily used for statistical purposes, such as estimating how many people in the country are living in poverty. The HHS poverty guidelines are a simplified version of the thresholds and are used administratively to determine eligibility for many programs. If you are applying for benefits, the guidelines are usually the numbers that matter.

Programs and decisions that may use FPL

• Medicaid and CHIP eligibility screening
• Affordable Care Act Marketplace premium tax credits
• Cost-sharing reductions in certain Marketplace contexts
• Hospital and clinic financial assistance policies
• Community health center sliding fee scales
• Some state and local assistance programs
• Nutrition, housing, and educational support programs that use poverty-related standards

Not every program uses exactly the same income definition. Some use gross income. Others use modified adjusted gross income. Some consider expected annual income, while others use current monthly income. This is why your FPL percentage may differ across applications even if your wages are unchanged.

Mistakes to avoid when calculating FPL

1. Using the wrong year: Poverty guidelines change each year, so make sure you use the current schedule required by the program.
2. Forgetting to annualize income: Monthly income cannot be compared directly to an annual poverty guideline.
3. Choosing the wrong household size: Even one extra household member changes the denominator.
4. Using net income instead of the required income definition: Different programs may ask for different income measures.
5. Ignoring location: Alaska and Hawaii have higher guideline amounts.

Bottom line

So, how do you calculate federal poverty level? You identify the correct poverty guideline for your household size and region, convert your income to an annual amount, divide income by the guideline, and multiply by 100. That percentage is what agencies and program administrators often use to decide whether you may qualify for benefits or reduced costs. It is a straightforward formula, but accuracy depends on choosing the right household definition, income type, and poverty guideline year. With the calculator on this page, you can estimate your position quickly and understand whether you are near commonly used thresholds like 138%, 200%, or 250% of FPL.
