"Living wage" and "minimum wage" get used interchangeably a lot, but they're not the same thing, and mixing them up leads to some genuinely confusing conversations. Here's the difference, in plain terms.
What Is a Living Wage?
A living wage is an estimate of what a person actually needs to earn to cover basic expenses in a specific place: housing, food, childcare, transportation, health care, and taxes. It's not set by any single law. Instead, it's calculated by researchers, most notably MIT's Living Wage Calculator project, using real local cost data for a given county or metro area. Because it's tied to local costs, a living wage in San Francisco looks very different from a living wage in rural Mississippi.
MIT's Living Wage Calculator defines a living wage as the hourly rate an individual must earn to cover basic family expenses, including food, housing, transportation, and health care, in a specific US county or metro area.
How Living Wage Estimates Are Actually Calculated
Unlike a minimum wage, which is a single number written into a statute, a living wage estimate is built from the ground up, county by county. The standard approach, and the one MIT's Living Wage Calculator is built on, prices out a defined basket of necessities for a specific household type in a specific location, then works backward to the hourly wage a full-time worker would need to earn to cover that basket. The inputs typically include:
- Housing — rent for a modest local apartment or home
- Food — a basic grocery budget, not restaurant spending
- Child care — for household compositions that include children
- Medical costs — insurance premiums plus expected out-of-pocket spending
- Transportation — commuting costs by car or public transit
- Other necessities — clothing, personal care, and household supplies
- Taxes — payroll and income taxes owed on the resulting wage
Because each line item is priced with local data rather than a national average, the same methodology produces sharply different results depending on where it's run and which household type is being modeled.
What is a minimum wage?
A minimum wage is a specific dollar figure set by law, whether federal, state, or city, that an employer is legally required to pay. It doesn't adjust automatically for local cost of living unless a state or city has specifically written that adjustment into its own law (some do, most don't). The federal minimum wage under the Fair Labor Standards Act has been $7.25 per hour since 2009.
The core difference
A minimum wage is a legal floor. A living wage is an economic estimate of adequacy. A minimum wage can be, and in most of the country currently is, well below the calculated living wage for that area. That gap is the entire reason "living wage" comes up as a distinct concept at all: it's a way of asking whether the legal minimum is actually enough to live on, not just what the law happens to require.
Why the living wage varies so much by location
Housing costs are usually the single biggest driver. A living wage calculation for a high-cost coastal metro can be two to three times higher than the same calculation for a low-cost rural county, even within the same state, because rent and home prices vary that dramatically. Household composition matters too: the estimate for a single adult is lower than for an adult supporting children, since childcare and food costs scale with family size.
Why Household Size Changes the Number Just as Much
Geography sets the price level, but household size determines which basket of costs is even being priced. A single adult and a single parent with two children in the exact same county can end up with living wage figures that differ substantially, because child care and food costs for dependents don't shrink just because the local rent is cheap. Adding a second working adult changes things differently: total household costs rise, but so does the number of incomes assumed to be covering them, which can lower the required hourly wage per adult even as the overall household budget grows. That's why living wage figures are always published per household type rather than as one number per place.
How Does the Living Wage Compare to State Minimum Wages Today?
Even the highest state minimum wages in the country, like Washington's $17.13/hr, often fall short of the calculated living wage for high-cost metro areas within that same state, though they can be close to or above the living wage estimate in lower-cost parts of the state. This gap is largest in expensive coastal cities and smallest in lower cost-of-living regions, which is why a single statewide minimum wage can be well above a living wage in one county and well below it in another. See every state's current minimum wage to compare against your own local living wage estimate.
Does Any Law Require Employers to Pay a Living Wage?
Generally, no. A small number of cities and counties have enacted their own "living wage ordinances," which function like a local minimum wage, but they're a specific legal category and only apply in the places that have actually passed one. Absent one of those ordinances, employers are only legally required to meet the applicable minimum wage, not a living wage estimate.
That distinction matters for anyone comparing wage figures online: a living wage number is a research estimate, not an enforceable rate, unless it's been formally adopted as a local ordinance. No state and no federal law has adopted MIT's or any other organization's living wage calculation as its legal minimum wage. The number that actually governs what an employer must pay is always the applicable federal, state, or local minimum wage.

How the Gap Gets Used in Policy Debates
The distance between a jurisdiction's legal minimum wage and its calculated living wage shows up constantly in debates over whether the minimum wage should be raised. Advocates for higher minimum wages routinely point to the size of that gap as evidence that a full-time, minimum-wage job doesn't cover a household's basic costs in a given area, using the living wage estimate as a benchmark for what "enough" would look like. Critics of specific proposals sometimes push back on the methodology itself, arguing that assumptions built into the calculation, such as the size of the housing or child care budget, run higher than a given worker's actual situation requires. Either way, the living wage figure functions as a reference point in that argument rather than as a rule anyone is legally bound by. It puts a number on the question "is this enough to live on," which minimum wage law, being a flat legal floor, doesn't attempt to answer on its own.
Frequently Asked Questions
Is a living wage the same as a minimum wage?
No. A minimum wage is a legal floor set by law. A living wage is an economic estimate of what's needed to cover basic expenses in a specific area, and is often significantly higher than the legal minimum wage.
Who calculates the living wage?
Most commonly, MIT's Living Wage Calculator project, which publishes county-by-county and metro-area estimates based on local cost data across the US.
Is there a national living wage figure?
Not a single one. Because living wage estimates are tied to local costs, they vary by county and household composition rather than existing as one national number.
Do any US laws require a living wage?
Only in the specific cities and counties that have passed their own "living wage ordinance." Outside of those, employers are legally required to pay only the applicable minimum wage.
Does a living wage estimate account for taxes?
Yes. The methodology behind MIT's Living Wage Calculator builds expected payroll and income taxes into the target hourly figure, so the published number already reflects what a worker needs to earn to cover both living expenses and taxes owed on that income.
How much does household size change the living wage figure?
Substantially. Adding a child changes the cost side of the calculation, since food and child care get added to the basket, while adding a second working adult changes the income side, since two incomes are then assumed to cover the household's costs. That's why living wage estimates are tied to a specific household composition rather than reported as one figure per location.
