Policy Basics: Introduction to the Supplemental Nutrition Assistance Program (SNAP)

January 8, 2015

What Is SNAP?

The Supplemental Nutrition Assistance Program (SNAP, formerly known as the Food Stamp Program) is the nation’s most important anti-hunger program.  In 2014, it helped more than 46 million low-income Americans to afford a nutritionally adequate diet in a typical month.

Close to 70 percent of SNAP participants are in families with children; more than one-quarter are in households with seniors or people with disabilities.

After unemployment insurance, SNAP is the most responsive federal program providing additional assistance during economic downturns.  It also is an important nutritional support for low-wage working families, low-income seniors, and people with disabilities living on fixed incomes.

The federal government pays the full cost of SNAP benefits and splits the cost of administering the program with the states, which operate the program.

Who Is Eligible for SNAP?

Unlike most means-tested benefit programs, which are restricted to particular categories of low-income individuals, SNAP is broadly available to almost all households with low incomes.  SNAP eligibility rules and benefit levels are, for the most part, set at the federal level and uniform across the nation, though states have flexibility to tailor aspects of the program, such as the value of a vehicle a household may own and still qualify for benefits.  Under federal rules, to qualify for SNAP benefits, a household must meet three criteria (although states have flexibility to adjust these limits):

  • Its gross monthly income generally must be at or below 130 percent of the poverty line, or $2,144 (about $25,700 a year) for a three-person family in fiscal year 2015.  Households with an elderly or disabled member need not meet this limit.
  • Its net monthly income, or income after deductions are applied for items such as high housing costs and child care, must be less than or equal to the poverty line (about $19,800 a year or $1,650 a month for a three-person family in fiscal year 2015).
  • Its assets must fall below certain limits:  in fiscal year 2015 the limits are $2,250 for households without an elderly or disabled member and $3,250 for those with an elderly or disabled member.

Some categories of people are not eligible for SNAP regardless of how small their income or assets may be, such as strikers, most college students, and certain legal immigrants.  Undocumented immigrants also are ineligible for SNAP. 

Most unemployed childless adults are limited to three months of benefits in many areas of the country, unless they are working at least 20 hours per week or participating in a qualifying workfare or job training program.  States may seek temporary waivers from this time limit during times of high unemployment, when qualifying jobs are scarce.  To receive a waiver, states must provide detailed Labor Department unemployment data for the state or areas within the state that demonstrate sustained levels of high unemployment. 

Currently much of the United States qualifies for a waiver, but starting in 2016, fewer states will be eligible for waivers and more individuals will be subject to the time limit. CBPP estimates that if current trends continue, nearly every state will be implementing the time limit in at least some areas in 2016.  Roughly 1 million people will be cut off SNAP as a result.

How Do People Apply for SNAP?

Each state designs its own SNAP application process, following federal guidelines.  In most states, households apply in person at the welfare office, though they can also mail or fax their applications, and most states have online applications.  Applicants must participate in an eligibility interview, which is typically in-person but can be on the phone.  They must also document numerous aspects of their eligibility, including their identity, residency, immigration status, household composition, income and resources, and deductible expenses.

Households found to be eligible receive an EBT (electronic benefit transfer) card, which is loaded with benefits once a month.  Household members may use it to purchase food at one of the 252,900 retailers authorized to participate in the program.  More than 80 percent of benefits are redeemed at supermarkets or superstores.  SNAP cannot be used to purchase alcoholic beverages, cigarettes, vitamin supplements, non-food grocery items such as household supplies, or hot foods.

Households must contact the welfare office to report if their income goes up dramatically.  They also must reapply for SNAP periodically, typically every six to 12 months for most families and every 12 to 24 months for seniors and people with disabilities.

How Much Do Households Receive in Benefits?

The average SNAP recipient received about $125 a month (or about $4.17 a day) in fiscal year 2014. 

The SNAP benefit formula targets benefits according to need:  very poor households receive larger benefits than households closer to the poverty line since they need more help affording an adequate diet.  The benefit formula assumes that families will spend 30 percent of their net income for food; SNAP makes up the difference between that 30 percent contribution and the cost of the Thrifty Food Plan, a low-cost but nutritionally adequate diet established by the U.S. Agriculture Department.

A family with no net income receives the maximum benefit amount, which equals the cost of the Thrifty Food Plan for a household of its size (see table).  For example, a family of three with $600 in net monthly income receives the maximum benefit ($511) minus 30 percent of its net income (30 percent of $600 is $180), or $331.

The maximum benefit was higher from April 2009 through October 2013 due to a benefit increase in the 2009 Recovery Act.  That boost ended in November 2013, resulting in a benefit cut for nearly every SNAP household.  In fiscal year 2014, monthly benefits averaged about $8 less per person — and about $18 less per household — than the previous year.

That is a serious loss, especially in light of the very low basic SNAP benefit levels. Research suggests that changing SNAP benefit amounts affects the share of SNAP participants who are “food insecure,” meaning they had difficulty affording adequate food at some point in the year. Food insecurity fell among SNAP-eligible households in 2009, when the Recovery Act benefit boost took effect, but then rose from 2009 to 2011, when the benefit boost eroded in value due to inflation.

How Much Does SNAP Cost?

In fiscal year 2014, the federal government spent $76 billion on SNAP.  About 92 percent went directly to benefits that households used to purchase food.  Of the remaining 8 percent, about 5 percent was used for state administrative costs, including eligibility determinations, employment and training and nutrition education for SNAP households, and anti-fraud activities.  About 3 percent went for other food assistance programs, such as the block grant for food assistance in Puerto Rico and American Samoa, commodity purchases for the Emergency Food Assistance Program (which helps food pantries and soup kitchens across the country), and commodities for the Food Distribution Program on Indian Reservations.


SNAP experienced large but temporary growth in recent years.  Caseloads expanded significantly between 2007 and 2011 as the recession and lagging economic recovery dramatically increased the number of low-income households who qualified and applied for help.  In addition, SNAP delivered more than $40 billion in economic stimulus through the Recovery Act benefit increases. 


These changes were temporary, however.  SNAP caseloads grew more slowly in 2012 and 2013 and fell by 2 percent in 2014. As of early 2015, caseloads were falling in about 40 states, following the pattern of recovery from earlier recessions.   

SNAP spending has fallen as well, due to declining caseloads as well as a drop in average benefits. SNAP benefits fell by 6 percent in 2014, reflecting the end of the Recovery Act benefit increase.  As a result, SNAP spending fell as a share of the economy (gross domestic product  or GDP) by 11 percent in 2014, returning to close to its 2009 level.  The Congressional Budget Office (CBO) projects that SNAP spending will fall to 1995 levels as a share of GDP by 2020.  As currently structured, SNAP is not contributing to long-term budgetary pressures.

Special Features of SNAP

While SNAP’s fundamental purpose is to help low-income families, the elderly, and people with disabilities afford an adequate diet, it promotes other goals as well: 

Protecting families from hardship and hunger

SNAP benefits are an entitlement, which means that anyone who qualifies under program rules can receive benefits.  As a result, SNAP responds quickly and effectively to support low-income families and communities during times of increased need.  Enrollment expands when the economy weakens and contracts when the economy recovers.  In this way, SNAP helps families to bridge temporary periods of unemployment or a family crisis.  If a parent loses her job or has a job that pays low wages, SNAP can help her feed her children until she is able to improve her circumstances.


SNAP helps households with limited resources to purchase adequate food.  Some 17.5 million households, with 49 million people, were food insecure in 2013.  Studies show that SNAP benefits have reduced food insecurity for those households.

Protecting the overall economy

SNAP benefits are one of the fastest, most effective forms of economic stimulus because they get money into the economy quickly.  Low-income individuals generally spend all of their income meeting daily needs such as shelter, food, and transportation, so every dollar in SNAP that a low-income family receives enables the family to spend an additional dollar on food or other items.  Some 80 percent of SNAP benefits are redeemed within two weeks of receipt and 97 percent are spent within a month.

Moody’s Analytics estimates that in a weak economy, every $1 increase in SNAP benefits generates about $1.70 in economic activity.  Similarly, CBO has found that SNAP has one of the largest “bangs-for-the-buck” (i.e. increase in economic activity and employment per budgetary dollar spent) among a broad range of policies for stimulating economic growth and creating jobs in a weak economy.

Lessening the extent and severity of poverty and unemployment

SNAP is heavily focused on the poor. About 92 percent of SNAP benefits go to households with incomes below the poverty line, and 57 percent go to households below half of the poverty line (about $9,895 for a family of three in 2014).  Families with the greatest need receive the largest benefits, as noted above.  

These features make SNAP a powerful antipoverty tool.  A CBPP analysis using the government’s Supplemental Poverty Measure, which counts SNAP as income, found that SNAP kept 4.8 million people out of poverty in 2013, including 2.1 million children.  SNAP lifted 1.3 million children above half of the poverty line in 2013..

SNAP is also effective in reducing extreme poverty.  A National Poverty Center study estimated the number of U.S. households earning less than $2 per person per day, a definition of poverty the World Bank uses for developing nations.  The study found that counting SNAP benefits as income cut the number of extremely poor families with children in 2011 by 48 percent (from 1.65 million to 857,000) and cut the number of children in extreme poverty by more than half (from 3.6 million to 1.2 million).

The deep and prolonged recession and weak recovery have made SNAP especially valuable to low-income unemployed workers.  Long-term unemployment ? defined as being unemployed for 27 weeks or longer ? was sharply higher in the recession than in any previous downturn (with data going back to the late 1940s) and remains unusually high, despite a significant decline over the past few years. 

SNAP is one of the few resources available for individuals who have exhausted their unemployment benefits.  While the number of unemployed workers has fallen since 2010, the number of jobless workers who receive no state or federal UI benefits has risen and is higher now than at the depths of the recession.

Supporting and encouraging work

In addition to acting as a safety net for people who are elderly, disabled, or temporarily unemployed, SNAP is designed to supplement the wages of low-income workers.

The number of SNAP households that have earnings while participating in SNAP has more than tripled — from about 2 million in 2000 to about 7.1 million in 2013.   The share of all SNAP households that have earnings while participating in SNAP has also increased — from about 27 percent in 2000 to about 31 percent in 2013.  


The increase was especially pronounced during the recent deep recession, suggesting that many people have turned to SNAP because of under-employment — for example, when one wage earner in a two-parent family lost a job, a worker’s hours were cut, or a worker turned to a lower-paying job after being laid off.

SNAP benefits help low-wage working families make ends meet.  For a family of three with one wage earner who works at $10 an hour, SNAP increases the family’s take-home income by roughly 14 percent to over 20 percent, depending on the number of hours worked.

policybasics-foodstamsp-rev1-8-15-f5.pngIn addition, the SNAP benefit formula contains an important work incentive.  For every additional dollar a SNAP recipient earns, her benefits decline by only 24 to 36 cents — much less than in most other programs.  Families that receive SNAP thus have a strong incentive to work longer hours or to search for better-paying employment.  States further support work through the SNAP Employment and Training program, which funds training and work activities for unemployed adults who receive SNAP.

Most SNAP recipients who can work do so.  Among SNAP households with at least one working-age, non-disabled adult, more than half work while receiving SNAP — and more than 80 percent work in the year before or after receiving SNAP.  The rates are even higher for families with children.  (About two-thirds of SNAP recipients are not expected to work, primarily because they are children, elderly, or disabled.)

Supporting healthy eating

SNAP enables low-income households to afford more healthy foods.  Because SNAP benefits can be spent only on food, they boost families’ food purchases more than an equivalent amount of cash assistance would.  Fruits and vegetables, grain products, meats, and dairy products comprise almost 90 percent of the food that SNAP households buy.  In addition, all states operate SNAP nutrition education programs to help participants make healthy food choices.  

Recent research on the nationwide expansion of food stamps in the 1960s and 1970s finds that children born to poor women with access to food stamps had better health outcomes as adults — and girls grew up to be more self-sufficient — than those born in counties that had not yet implemented the program. 

Responding quickly to disasters
States can provide emergency SNAP within a matter of days to help disaster victims purchase food.  In 2014, SNAP helped households affected by storms in Illinois and Kentucky, an earthquake in California, and storms and flooding in Alabama, Arkansas, Michigan, and Mississippi.

How Effective and Efficient Is SNAP?

SNAP and other nutrition programs have helped make severe hunger in America rare.  Before the late 1960s, when the federal government began providing nutrition assistance, hunger and severe malnutrition could be found in many low-income communities in the United States. Today, in large part because of these programs, such severe conditions are no longer found in large numbers.

To promote efficiency, SNAP has one of the most rigorous quality control systems of any public benefit program.  Its error rates stand at record
lows; fewer than 1 percent of SNAP benefits are issued to households that do not meet all of the program’s eligibility requirements.


At the same time, SNAP reaches a large share of eligible households. Eighty-three percent of individuals who qualified for SNAP benefits received them in fiscal year 2012.  This represents a significant improvement from 2002, when the participation rate bottomed out at 54 percent.  Participation among eligible people in low-income working families rose from 43 percent in 2002 to about 72 percent in 2012. 

Nonetheless, many low-income households that receive benefits still have trouble affording an adequate diet.  An Institute of Medicine report identified several shortcomings with the current SNAP benefit allotment and noted that most household benefit levels are based on unrealistic assumptions about the cost of food, time preparation, and access to grocery stores.  Many families face stark choices between purchasing food and paying for rent and other necessities.  If they manage this shortfall by buying less-nutritious foods, it can adversely affect their health:  many low-cost, energy-dense foods that contribute to obesity are cheaper than nutritious foods such as fruits and vegetables.
