What is the Cost of Living and What Affects it?

We incur a ton of expenses every single day that we have to pay in order to live and to live comfortably. That being said, there are certain terms that refer to those costs that we should know about. Cost of living is a typical term that most people have heard at one point or other, and learning what it means can help you make some critical decisions. According to the U.S. Bureau of Labor Statistics (BLS), consumer prices have risen significantly over the past several years, making it more important than ever to understand what cost of living really means for your financial health.

What Does Cost of Living Mean?

Cost of living is a term that is used to refer to the cost of everyday items that we have to have in order to live. This can be things like groceries, gas costs, insurance costs, the cost of your home, the cost of basic necessities and so on. This is a term that is often thrown around and that many people can give you a basic idea about if you take the time to ask them. Financial institutions like SoFi and Chase have published extensive resources breaking down cost of living metrics for consumers trying to make informed financial decisions.

That being said, the cost of living is not the same across the board for all people. For some, the cost of living is much higher than others, and for others, the cost of living does not include all the same things that you might think are necessary to live. Overall, the cost of living is just a basic term that acts as an umbrella to encompass all the things that we deem necessary to live and that we feel is necessary to have a comfortable life.

Why is Cost of Living Different in Different Places?

The cost of living varies from place to place for a few reasons. For starters, the population density of an area does affect the cost of living in that area. Areas that are very densely populated are more likely to have a higher cost of living than an area where there are few people. The reason for this is that there is a larger demand for those things that we deem as part of a living. The Economic Policy Institute’s Family Budget Calculator demonstrates this clearly, showing that a family of four in San Francisco needs over $148,000 annually to cover basic expenses, while the same family in rural Mississippi may need only $65,000.

A city like New York, New York is going to cost far more than a city like New Haven, Kentucky. The cost is going to be directly relational to the number of people and the demand for those basic necessities that we all have to have. There is no real equation that you can use to determine the cost of living in one area or other, but you can do some basic math and get an idea of what the cost of living is in that area by looking at things like the cost of electricity, the cost of a well known grocery item, the cost of gas, and even the cost of housing. Tools provided by the Council for Community and Economic Research (C2ER), which publishes the widely used Cost of Living Index (COLI), allow consumers and researchers to compare these costs city by city using standardized data.

Cost of Living by City: A Data Comparison

The difference in cost of living between U.S. cities is stark and measurable. The table below uses index scores where 100 represents the U.S. national average. A score of 150, for example, means a city is 50% more expensive than the national average across the tracked categories.

What Does Cost of Living Mean For Wages?

When it comes to working and to earning a paycheck in any one area, the cost of living has a slightly different meaning. The cost of living is often used to help calculate the raise that an employee is going to get with every year that they work. This is referred to as the cost of living raise. It reflects things like inflation. Again, this is going to be related to the area in which the employee lives. The Federal Reserve tracks inflation closely, and its monetary policy decisions — including interest rate adjustments — directly influence wage growth and the purchasing power of workers across the country.

You are going to see this raise in terms of the cost of inflation rather than the cost of your performance. This means that everyone is going to get this type of raise no matter how they work. In most instances, cost of living raises are not going to be a set cent amount on your check, but rather a percentage that is going to be added to your check based on your hourly wage.

Cost of living raises are also applicable to things like disability benefits, social security benefits, and more government benefits that you might be getting. This is generally a blanket percentage that is determined by the government to help those that are living off of social security to be able to still have a comfortable life even though there is inflation. The Social Security Administration (SSA) announced a 2.5% COLA for 2025, the mechanism by which over 70 million Social Security and Supplemental Security Income (SSI) beneficiaries received an automatic increase in their monthly payments to offset the effects of rising consumer prices.

How Inflation Is Measured and Why It Matters for Cost of Living

Inflation is the engine that drives most cost of living changes. The primary tool used to measure inflation in the United States is the Consumer Price Index (CPI), published monthly by the Bureau of Labor Statistics (BLS). The CPI tracks price changes for a standardized “basket” of goods and services, including food, housing, apparel, transportation, medical care, and education.

When the CPI rises, the cost of living effectively increases — meaning the same dollar buys less than it did the prior month or year. This is why your grocery bill might feel higher even when you’re buying the same items. As of early 2026, the BLS reports that the CPI for All Urban Consumers (CPI-U) has risen approximately 3.1% year-over-year, signaling continued, if moderating, inflationary pressure on household budgets.

The Federal Reserve’s target inflation rate is 2% annually. When inflation runs above that level, the Fed typically raises the federal funds rate to slow borrowing and spending — moves that ripple through mortgage rates, credit card APRs, and business investment, all of which ultimately affect your cost of living at a personal level.

The Difference Between CPI and the Cost of Living Index

It’s worth noting that the CPI and the Cost of Living Index (COLI) are related but distinct measurements. The CPI measures price changes over time for a fixed set of goods. The COLI, maintained by organizations like the C2ER, measures the relative cost of maintaining a constant standard of living across different geographic locations at a single point in time. Employers frequently use COLI data to benchmark salaries when relocating employees or setting compensation levels for remote workers in different cities.

What Affects the Cost of Living?

There are four different factors that are taken into account when determining the cost of living. First, the cost of adequate housing. This means a home that is safe and that meets the needs of all the people living there, including dependent children. Another factor is the cost of health care. This means how much it costs to have adequate healthcare that you can use to go to the doctor, get necessary medication and other medical care.

The next factor is going to be the cost of transportation. This can mean the cost of gas, the cost of using public transit, the cost of a vehicle and even the cost of car insurance. The last factor that is taken into account is the cost of food. This is food that is adequate enough to keep you and the people that you care for healthy and well fed.

These are the four factors that most people consider when they are looking at the cost of living and are determining how much the cost of living in any one area and any one city. The cost of living is something that you are going to have to consider no matter what and no matter where you are living.

A Deeper Look at Each Cost of Living Factor

1. Housing Costs

Housing is consistently the largest single expense for American households, consuming an average of 33% of pre-tax income according to the BLS Consumer Expenditure Survey. The U.S. Department of Housing and Urban Development (HUD) defines “housing cost burdened” as spending more than 30% of gross income on housing — and as of 2025, approximately 46% of renter households fall into that category, according to the Harvard Joint Center for Housing Studies.

Housing costs include not just rent or mortgage payments, but also property taxes, homeowner’s or renter’s insurance, utilities, and maintenance. When the Federal Reserve raises interest rates, mortgage rates rise in tandem — the average 30-year fixed mortgage rate stood at approximately 6.8% in March 2026, according to Freddie Mac’s Primary Mortgage Market Survey, significantly impacting affordability for prospective buyers.

2. Healthcare Costs

Healthcare is one of the fastest-growing components of the cost of living in the United States. According to the Centers for Medicare & Medicaid Services (CMS), national health expenditure reached $4.9 trillion in 2024, representing approximately 18.3% of GDP. For individual households, this translates to thousands of dollars annually in premiums, deductibles, copays, and out-of-pocket prescription drug costs.

Your credit profile can also indirectly affect your healthcare costs — medical debt is a leading driver of credit score deterioration, and your FICO Score (the most widely used credit scoring model, developed by the Fair Isaac Corporation) influences the loan rates and financial products available to you when managing unexpected medical bills. Credit bureaus like Experian have published resources specifically on how healthcare costs intersect with personal finance and credit health.

3. Transportation Costs

Transportation is the second-largest household expense category in the U.S., representing approximately 16% of average household spending, according to the BLS. This includes vehicle purchase or lease payments, auto insurance premiums, fuel, public transit fares, parking, and vehicle maintenance.

The average annual cost of owning and operating a new vehicle reached $12,182 in 2025, according to AAA’s annual Your Driving Costs study — a figure that includes depreciation, loan interest, insurance, fuel, maintenance, and taxes. For households in cities with robust public transit systems, like New York City or Chicago, transportation costs may be significantly lower, as monthly subway or bus passes cost far less than car ownership. The Consumer Financial Protection Bureau (CFPB) recommends keeping total transportation costs below 15% of your take-home pay as part of a healthy household budget.

4. Food Costs

Food expenditures represent approximately 12–13% of average household budgets in the United States, split between food at home (groceries) and food away from home (restaurants, takeout). The USDA Economic Research Service publishes monthly food price outlooks, and as of early 2026, grocery prices remain elevated compared to pre-2021 levels, with certain categories like eggs, dairy, and fresh produce showing the most significant year-over-year increases.

The USDA’s Thrifty Food Plan — the basis for Supplemental Nutrition Assistance Program (SNAP) benefit calculations — was updated in 2021 to reflect a more realistic estimate of what it costs to eat a nutritionally adequate diet. As of 2025, the maximum monthly SNAP benefit for a family of four is $973, though many nutrition researchers argue this still falls short of actual grocery costs in high-cost metro areas.

Additional Factors That Influence Cost of Living

Beyond the four core factors, several additional economic forces shape the cost of living for households across the United States.

State and Local Taxes

State income taxes, property taxes, and sales taxes all affect how far your dollar stretches. States with no income tax, like Florida, Texas, and Nevada, may appear less expensive on paper — but they often compensate with higher property taxes or sales taxes. The Tax Foundation’s State Business Tax Climate Index provides annual rankings of state tax environments, which directly affect the real cost of living for residents.

Childcare and Education

For families with children, childcare and education costs are enormous cost of living drivers. The average annual cost of center-based childcare for an infant in the U.S. reached $18,000 in 2025, according to the National Association of Child Care Resource & Referral Agencies. In high-cost states like Massachusetts and California, that figure can exceed $25,000 per year — more than in-state college tuition at many public universities.

Debt Service Costs

The cost of carrying debt — including student loans, credit card balances, auto loans, and mortgages — is an increasingly significant component of effective cost of living for many American households. With average credit card APR (Annual Percentage Rate) hovering around 21.5% in early 2026, according to the Federal Reserve’s G.19 Consumer Credit report, debt service costs can consume a substantial portion of monthly income. Your Debt-to-Income Ratio (DTI) — the percentage of your gross monthly income that goes toward debt payments — is a key metric monitored by lenders like Chase, SoFi, and other financial institutions when you apply for mortgages or personal loans. The CFPB recommends keeping your DTI below 36% to maintain financial flexibility and qualify for favorable loan terms.

The cost of living does fluctuate from month to month and something that was once affordable can end up being very expensive in the months that follow. Cost of living affects all of us, no matter if we work or not, and it does affect how much money we need to make in order to have a good life and to be able to afford the things that we need to be able to live.

Cost of living is something that the government also does a yearly report on so that you can look at the trends and so that you can look at what possible future trends might be as well. The Bureau of Labor Statistics publishes the annual Consumer Expenditure Survey, which provides a detailed breakdown of how American households allocate their spending across all major categories. The FDIC (Federal Deposit Insurance Corporation) also publishes research on household financial health that intersects closely with cost of living trends, particularly for lower-income Americans. Cost of living isn’t going anywhere, and learning about what it is and what it means can help you better understand your financial situation.

How to Use Cost of Living Data to Make Smarter Financial Decisions

Understanding cost of living data is not just an academic exercise — it has direct, practical applications for major life decisions. Here are the most common scenarios where cost of living analysis can make or break your financial outcome.

Evaluating a Job Offer in a New City

A higher salary in a new city doesn’t automatically mean a better financial outcome. If you’re earning $80,000 in Memphis, Tennessee, and receive a $110,000 offer in New York City, the raw numbers look compelling. But after accounting for New York’s cost of living index of 187 versus Memphis’s 84, your effective purchasing power in New York is actually lower than it was in Memphis. Tools like the NerdWallet Cost of Living Calculator allow you to input two cities and a salary figure to calculate the equivalent salary needed to maintain your current standard of living.

Planning for Retirement

Retirees often relocate to lower cost of living states to stretch their retirement savings further. The Social Security Administration (SSA) notes that your Social Security benefits are calculated based on your lifetime earnings history — not where you retire. This means a retiree who moves from San Francisco to Tucson, Arizona, receives the same monthly SSA benefit but lives in a city with a cost of living index of roughly 95, versus San Francisco’s 178. That geographic arbitrage can add years of financial runway to a retirement portfolio managed by institutions regulated by the FDIC and Federal Reserve.

Budgeting for Major Life Changes

Whether you’re having a child, buying a home, or going back to school, factoring cost of living data into your budget is essential. The CFPB offers free budgeting tools and worksheets at consumerfinance.gov that can help you model how major life changes will affect your monthly cash flow against the cost of living in your area. Maintaining a healthy FICO Score through responsible credit use — tracked by credit bureaus like Experian, Equifax, and TransUnion — also ensures you have access to credit products with favorable rates when your cost of living temporarily spikes due to life events.

Frequently Asked Questions

What is cost of living in simple terms?

Cost of living is the amount of money you need to cover basic necessities — housing, food, healthcare, and transportation — in a specific location. It varies significantly by city, state, and country, and is used to compare how affordable different areas are for everyday life.

What are the four main factors that affect cost of living?

The four primary factors are housing costs, healthcare costs, transportation costs, and food costs. These four categories are used by economists, government agencies like the BLS, and tools like the EPI Family Budget Calculator to measure and compare cost of living across different regions.

Which U.S. city has the highest cost of living in 2026?

As of March 25, 2026, New York City consistently ranks as one of the most expensive U.S. cities, with a cost of living index of approximately 187 — 87% higher than the national average. San Francisco, CA, and Honolulu, HI, also rank among the top three most expensive cities for everyday expenses.

What is a cost of living raise and how is it calculated?

A cost of living raise (also called a COLA — Cost-of-Living Adjustment) is a salary or benefit increase tied to inflation rather than job performance. For government benefits like Social Security, the SSA calculates COLA based on the percentage increase in the CPI-W (Consumer Price Index for Urban Wage Earners and Clerical Workers) from the third quarter of the prior year. The 2025 COLA was set at 2.5%.

How does inflation affect the cost of living?

Inflation directly increases the cost of living by reducing the purchasing power of money — meaning you pay more dollars for the same goods and services. The Federal Reserve targets a 2% annual inflation rate. When inflation exceeds that target, as it did significantly between 2021 and 2024, the real cost of living rises faster than wages for many households, reducing their standard of living even without any change in spending habits.

How is cost of living different from standard of living?

Cost of living refers specifically to the monetary cost of maintaining a basic standard of necessities in a given location. Standard of living is a broader concept that includes not just expenses but also quality of life factors like access to education, healthcare quality, environmental conditions, and personal safety. A city can have a high cost of living but also a high standard of living — and vice versa.

Does cost of living affect my credit score or borrowing ability?

Indirectly, yes. Living in a high-cost area can stretch budgets thin, increasing the risk of missed payments that damage your FICO Score. Your credit score, tracked by bureaus like Experian, Equifax, and TransUnion, directly affects the APR you receive on loans and credit cards. A lower FICO Score in a high-cost city can mean paying significantly more in interest — compounding your cost of living burden. The CFPB offers free guidance on managing credit in high cost-of-living environments.

What is the cheapest state to live in the United States?

Mississippi consistently ranks as the lowest cost of living state in the U.S., with a cost of living index of approximately 83 — 17% below the national baseline. Other affordable states include Oklahoma (85), Kansas (86), and Alabama (87), according to the C2ER Cost of Living Index 2025. These states tend to have lower housing costs, property taxes, and grocery prices compared to coastal states.

How does the government use cost of living data?

Federal and state governments use cost of living data in several critical ways: to calculate annual COLA adjustments for Social Security and SSI benefits (administered by the SSA), to set federal poverty guidelines (updated annually by HHS), to determine SNAP benefit levels (administered by the USDA), and to inform Federal Reserve monetary policy decisions that affect interest rates and inflation nationwide.

How can I compare cost of living between two cities before moving?

Several free tools allow city-to-city comparisons. The NerdWallet Cost of Living Calculator, the CNN Money Cost of Living Calculator, and the EPI Family Budget Calculator are all widely used. For salary equivalence calculations — determining what salary you’d need in a new city to maintain your current lifestyle — tools from SoFi and NerdWallet provide detailed breakdowns by expense category including housing, food, transportation, and healthcare.
