Two numbers dominate every conversation about pay in the United States, and they are often confused with each other. The minimum wage is a legal floor: the lowest hourly rate an employer may lawfully pay, set by federal or state law. The living wage is a calculated budget: the hourly pay a household needs to cover basic costs — housing, food, childcare, healthcare, and transport — without public assistance, as priced by the MIT Living Wage Calculator for the county where the household lives. The federal minimum wage has been $7.25 an hour since 2009. The MIT calculator puts the living wage for a single adult at about $22.70 an hour in a median US county. The gap between them is not a rounding difference; it is the difference between a law and a cost of living.

Two different ideas

The minimum wage and the living wage answer different questions. The minimum wage answers a legal question: what is the lowest rate an employer may pay? It is set by legislation, it applies to covered workers, and it is enforced by the Department of Labor and the states. The living wage answers an economic question: what hourly pay does a household need to meet its basic costs in a particular place? It is calculated from prices, it varies by county and by household size, and no law enforces it.

Confusing the two leads to two opposite errors. The first is treating the minimum wage as enough to live on, because it is the legal minimum — it is a floor, not a budget, and in most of the country it is far below the cost of basic needs. The second is treating the living wage as a legal entitlement, because it is called a wage — it is a benchmark, not a right, and an employer paying the legal minimum is not breaking the law even where the living wage is far higher. The companion guide on what a living wage is explains the calculation in full.

The numbers side by side

Table notes: federal minimum wage $7.25 an hour since July 2009 (US Department of Labor); Washington State $16.66 and Washington, D.C. $17.95 are 2025 rates; MIT figures are from the MIT Living Wage Calculator, 2025 update, for a single adult with no children working full-time. Annual figures are the hourly rate multiplied by 2,080 hours.

Three things stand out. First, the federal minimum is less than a third of the living wage in a median county: $7.25 against about $22.70. Second, even the highest state minimum wage, Washington’s $16.66, sits below the living wage in a low-cost county. Third, the living wage itself moves by place: a single adult needs $18.89 an hour in Ashe County, North Carolina, and $25.80 in King County, Washington — a gap of nearly $7 an hour for the same household, driven mostly by housing costs.

What the minimum wage is

The federal minimum wage is set by the Fair Labor Standards Act and has been $7.25 an hour since July 2009 — the longest stretch without an increase since the minimum wage was created. It applies to most workers, with exceptions for tipped workers, some young workers, and some small employers. States and cities may set higher minimums, and 30 states and Washington, D.C. now do. Washington State has the highest state rate at $16.66 an hour in 2025, and Washington, D.C. is higher still at $17.95.

The minimum wage is a floor with no connection to prices. It does not rise with inflation unless a legislature raises it, and it does not vary with the cost of living in a place unless a state or city sets its own rate. That is why it can sit far below the cost of basic needs for years at a time: the law does not ask what life costs, only what the floor is.

What the living wage is

The living wage is calculated, not legislated. The MIT Living Wage Calculator prices a basic-needs budget for a household in a specific county: housing, food, childcare, healthcare, transport, and the taxes owed on the income, with nothing else. The annual budget is divided by 2,080 hours — 40 hours a week for 52 weeks — to give the hourly wage that would cover it. The result is specific to the county and to the household: a single adult, a single parent with one child, and a two-parent household with two children all get different figures in the same county, because their costs differ.

The definition is deliberately modest. MIT describes the living wage as the basic income standard that, if met, draws a very fine line between the financial independence of the working poor and the need to seek public assistance or suffer consistent and severe housing and food insecurity. It is closer to a minimum subsistence wage than to a comfortable wage: it covers basic needs and nothing more. It does not include savings, debt repayment, restaurant meals, holidays, or any cushion for an emergency.

Why the gap is so large

The gap is large for two reasons, and both are structural. The first is time: the federal minimum wage has been frozen at $7.25 since 2009, while the costs the living wage tracks — rent, food, healthcare, childcare — have risen every year. A floor that never moves falls further behind prices with each passing year. The second is method: the minimum wage is a single national number, while the living wage is priced county by county. A single national floor cannot track local costs, and in expensive counties even a raised national floor would still sit below the living wage.

State minimum wages narrow the gap but do not close it. Washington’s $16.66 is the highest state rate in the country, and it is still below the $18.89 a single adult needs in a low-cost North Carolina county, and far below the $25.80 needed in King County, Washington itself. The gap is not a quirk of one state or one year; it is what happens when a frozen legal floor is compared with a priced budget.

The same question in the UK

The United Kingdom draws the same distinction with different names. The National Living Wage is the government’s mandatory minimum for workers aged 21 and over: £12.21 an hour, rising to £12.71 from April 2026. The Real Living Wage is the voluntary rate calculated by the Living Wage Foundation from the actual cost of living: £13.45 an hour across the UK and £14.80 an hour in London, as announced on 22 October 2025, with accredited employers given until 1 May 2026 to implement the new rates.

The pattern is the same as in the United States: the mandatory minimum sits below the calculated living wage, and the living wage is higher in London than elsewhere, because housing costs drive the difference. The UK’s gap is smaller than the American one — £12.21 against £13.45, rather than $7.25 against about $22.70 — because the UK’s mandatory minimum is updated annually and the American federal minimum has not moved since 2009.

What each figure is for

Use the minimum wage to know what an employer must pay, and use the living wage to know what a household needs. The minimum wage settles a legal question: if your pay is below the federal or state minimum, your employer is breaking the law. The living wage settles a budgeting question: if your pay is below the living wage for your county and household, your basic costs exceed your earnings, and the gap must be closed by a second income, by public assistance, by lower costs, or by a higher wage.

Neither figure tells you what you personally need. The living wage is priced for a standard household in a county, not for your household, and your own costs — your rent, your childcare, your health costs — are what set your own required wage. The living wage calculator on this site works from the costs you enter, rather than from a county average, and that is the figure to use for a personal decision.
