How Much One Parent Needs to Earn So the Other Can Stay Home in Every US State

For many families, one of the biggest financial questions after welcoming a child is whether one parent can afford to leave the workforce and stay home. While the idea appeals to many parents, new research shows that the answer largely depends on where you live.

A recent analysis by SmartAsset, using data from the Massachusetts Institute of Technology's Living Wage Calculator, estimated how much a single working parent would need to earn to support a household consisting of two adults and one child. The study considered essential expenses such as housing, food, healthcare, transportation, and taxes while excluding discretionary spending.

Hawaii Tops the List

According to the analysis, Hawaii is the most expensive state for a one-income family. A working parent would need to earn at least $102,773 annually to support a stay-at-home partner and one child. The state's high housing, food, and transportation costs continue to place significant financial pressure on families.

Other states requiring some of the highest incomes include:

• California: $97,656

• Massachusetts: $97,261

• New York: $92,290

• Connecticut: More than $90,000

• Washington: More than $90,000

These states combine high living expenses with costly housing markets, making it difficult for families to rely on a single paycheck.

The Most Affordable States for Single-Income Families

At the other end of the spectrum, several states offer lower living costs that make the stay-at-home-parent option more attainable.

The most affordable states include:

• West Virginia: $68,099

• Arkansas: $68,141

• Mississippi: $70,242

• Kentucky: $70,408

• North Dakota: $70,949

While these income thresholds are significantly lower than those in coastal states, experts note that average wages are also lower, which can still make budgeting challenging for many households.

Childcare Costs Are Driving the Conversation

One major factor influencing parents' decisions is the soaring cost of childcare. In many parts of the country, daycare expenses rival or exceed the cost of college tuition. Research cited in the analysis found that full-time childcare costs more than in-state public college tuition in 38 states and Washington, D.C.

For some families, the cost of childcare, commuting, and work-related expenses can consume a large portion of one parent's income. As a result, staying home may sometimes make more financial sense than continuing to work.

Beyond the Numbers

Financial planners caution that the decision involves more than monthly expenses. Leaving the workforce can affect retirement savings, career advancement, future earning potential, and long-term financial security. Families considering a one-income household are encouraged to review their budgets carefully and plan for unexpected expenses.

Ultimately, the study highlights a growing reality for American families: while a stay-at-home parent arrangement remains possible, the income required to make it work varies dramatically depending on location. For many households, the decision is no longer simply a lifestyle choice—it is a financial calculation shaped by the rising cost of living across the United States.
