What is SNAP? An Overview of the Largest Federal Anti-Hunger Program

The Supplemental Nutrition Assistance Program (SNAP) is the largest federal program aimed at combating hunger and food insecurity among low-income Americans. Sometimes referred to as food stamps, SNAP benefits are transferred to needy families through debit cards, which can be used to purchase food items in retail stores.

SNAP has demonstrated significant anti-poverty effects while comprising a fraction of federal spending. In fiscal year 2019, the most recent year for which a complete set of data is available, SNAP:

  • Assisted approximately 36 million low-income beneficiaries per month, lifting 2.5 million people out of poverty
  • Totaled $60 billion, or 1.4 percent of the federal budget
  • Averaged $258 per month (or $64.5 per week) per person in benefits

More recently, the coronavirus (COVID-19) pandemic has put the safety net to the test. The massive reduction of economic activity in 2020 put millions of Americans out of work, and many of those people became SNAP beneficiaries. In 2020, participation in the program increased by 12 percent relative to 2019.

Below is a look at how SNAP works, who benefits from it, and its place in the federal budget.

How Does SNAP Determine Eligibility and Benefit Levels?

SNAP benefits help to lift people out of poverty


Due to COVID-19, temporary changes have been made to SNAP to allow states to have additional flexibility and ease the administration of the program during the pandemic. However, in general, there are two paths for SNAP eligibility. Many participants are eligible for SNAP benefits because they receive assistance from other federal programs, such as Supplemental Security Income or Temporary Assistance for Needy Families. Households who do not receive assistance from those programs may still qualify for SNAP, but must meet certain income and asset tests. Apart from income eligibility standards, those age 16–59 generally must also register to work and accept suitable job offers to receive SNAP benefits. Of that group, able-bodied adults age 18–49 without dependents are limited to three months of benefits out of every three years unless they meet additional work requirements or are exempted by their state.

When calculating benefit amounts for SNAP, the U.S. Department of Agriculture (USDA) relies on its Thrifty Food Plan, a set of dietary guidelines designed to meet nutritional needs at a low cost. Based on those guidelines, the USDA sets maximum benefits for different household sizes, shown in the table below. Not including SNAP benefits received, families are expected to spend 30 percent of their net income on food.

Therefore, when determining benefits for individual households, USDA calculates 30 percent of a household’s net income and subtracts that amount from the maximum benefit amount to which that household is entitled. For example, if the maximum monthly benefit for a household with two people were $353 and the household’s net income totaled $500 per month, they would be expected to spend 30 percent of that, or $150, on food. Therefore, the monthly benefit would be $353-$150 = $203. In 2019, of all households receiving SNAP benefits in a given month, 36 percent received the maximum amount.

Over a third of households participating in SNAP receive the maximum benefit allowed


Currently, the maximum allotment for a family of four is $782 per month, which includes the temporary 15 percent increase that lawmakers enacted through September 2021 in response to the COVID-19 pandemic. Based on the latest reevaluation of the Thrifty Food Plan, USDA will permanently increase maximum SNAP benefit levels by 21 percent from pre-pandemic levels — raising average monthly benefits per person by $36. That boost, set to begin on October 1, 2021, is the largest increase in benefits in the program’s history and is separate from the COVID-related enhancements to the program.

More than 4 out of 5 households participating in SNAP live in poverty and receive over 90% of all benefits

Individuals and households must submit an application and undergo an interview to receive SNAP benefits. Once deemed eligible, they receive an Electronic Benefit Transfer (EBT) card that is automatically filled with the designated benefit amount every month. EBT cards work like debit cards and can be used at any authorized food store. Households cannot use their benefits to purchase items like cigarettes and alcohol, or for hot foods.

Some people are ineligible for SNAP for reasons other than failing to meet financial and work requirements. Those include individuals who are on strike, unauthorized immigrants, and some lawful non-citizens.

Who Benefits from SNAP?

The vast majority of SNAP participants live in poverty, the threshold for which was set at $25,100 a year for a household of four in 2018.1 In addition, about two-fifths of SNAP participants lived in “deep” poverty in fiscal year 2019, defined as those with incomes below 50 percent of the poverty threshold (or $12,550 for a family of four).

Snap participation varies greatly from state to state


SNAP is a wide-reaching program that provides support to many individuals and households across geographical boundaries. About 11 percent of all Americans participate in SNAP, and the rate of participation varies widely by state.



A majority of households receiving SNAP benefits include a child or an elderly or disabled person; according to the USDA, 39 percent of such households in fiscal year 2019 included children, and 47 percent contained someone who was elderly or disabled. However, many eligible people from those vulnerable groups do not receive any benefits. According to the latest report by the USDA, only 48 percent of eligible adults 60 and older were enrolled in the program in fiscal year 2018, in contrast to 82 percent of all eligible individuals. Many of them are unaware that they are eligible, believe that their benefits will be insignificant, or are unable to go to a grocery store to use the benefits.

SNAP beneficiaries are diverse


SNAP’s participants are racially diverse but not reflective of the population of people in poverty. While white Americans have one of the lowest poverty rates among all races, they comprise almost two-fifths of both SNAP participants and benefits received.

SNAP spending increased during the Great Recession, but is projected to decline below historical levels


How Much Does SNAP Cost?

SNAP comprises a very small portion of the federal budget and it is not a key driver of our federal debt. In 2020, spending for SNAP made up 1.3 percent of total federal spending. However, SNAP is a counter-cyclical income-security program, meaning that participation automatically — and by design — expands during economic downturns and shrinks in response to reduced need. As a result, spending has spiked, but CBO projects that SNAP spending will continue falling as a percentage of total outlays over the coming decade.

SNAP is the largest federal food assistance program


While SNAP is not a large part of the federal budget, it is the largest nutrition assistance program in the United States by far; the program alone constituted almost half of USDA’s budget and about 72 percent of all federal food assistance spending in fiscal year 2020. Whereas other nutrition assistance programs target specific populations like schoolchildren and new mothers, SNAP is generally available to households in need and therefore more responsive to fluctuations in the economy.

Proposed Changes to SNAP

In addition to helping individuals secure access to food, SNAP supports other goals such as promoting healthier diets, providing nutrition education to low-income families, and encouraging self-sufficiency through work requirements. Discussions about reforming the program therefore generally revolve around how to best achieve those goals. In particular, common themes include:

  • Health of the SNAP recipients: Policymakers have previously attempted to influence the dietary intake of SNAP recipients by discounting prices for fruits and vegetables, as well as restricting the use of SNAP money on “junk” foods like candies and soda.
  • Work requirements: One challenge faced by the program is keeping the balance between providing aid to those in need while preventing unnecessary dependence on public assistance. While a general work requirement is in place, many policymakers call for stricter tests for exceptions and waivers. On the other side of the spectrum, some have proposed reforms that would extend eligibility to certain groups of people, such as broadening the definition of work to include college students.
  • State vs. Federal: The federal government sets the income eligibility requirements and benefits levels for SNAP and also pays for the benefits. Meanwhile, the states are responsible for administering the program and for partially covering administrative expenses. Debate continues over which level of government should control the program. While supporters of uniform, nationwide policies argue that all SNAP participants should be subject to the same rules as set by the federal government, others believe state-level policies can better cater to the needs of specific geographic areas.


Ultimately, SNAP is a program with a small budgetary impact that benefits Americans who live near or in poverty. During the past year, it has proven to be a critical part of the safety net and enhanced spending on the program boosted economic growth. Nevertheless, several studies point out that the pandemic presented unique challenges that inhibited the program’s effectiveness. SNAP is not a significant cause of our nation’s overall fiscal imbalance, which is driven by structural factors stemming from an aging population and rising healthcare costs.
