Can We Afford for One Parent to Stay Home?

When childcare costs almost as much as a paycheck, staying home starts to look like a math problem you should be able to solve on a napkin.

You can start there. I wouldn't quit a job based on the napkin.

To see whether one parent can afford to stay home, compare the money you'd bring home with the bills and savings you'd still need to cover. Count what you'd stop paying and any new costs. Then check how much breathing room you'd have when things don't go as planned.

This works whether you're thinking about becoming a stay-at-home mom or dad. You can also compare smaller changes: fewer hours, a different job, a planned break, or waiting until the numbers improve.

Can one income cover your actual household costs?

Start with what your household spends now. Use recent pay stubs and bank statements, then look back far enough to catch annual bills and seasonal costs.

You need two numbers:

• What you have left now: your take-home pay minus spending and planned savings.
• What you'd have left on one income: your expected take-home pay minus the spending and savings you'd keep.

If that second number is below zero, the plan needs work. You'd need more income, lower costs, savings set aside for a short break, or more time to prepare. If it's above zero, check whether what's left gives your family enough room for a rough month.

Use the pay you'd actually bring home after taxes and other amounts taken out of your paycheck. If pay varies, start with a normal month you can count on. The best overtime month of the year shouldn't have to show up twelve times.

Treat childcare as a family expense. It helps make paid work possible for the household. If you compare it only with the smaller paycheck, you can miss the benefits and future work options that come with that job.

Which expenses actually go away when a parent stays home?

The useful number is the amount you will stop paying.

For childcare, ask how much notice you must give and whether you'll owe any fees when you leave. Include care you'd still use. A parent at home may need help for appointments, part-time work, or a break.

For transportation, start with gas, tolls, parking, and wear from driving to work. Car payments and insurance may stay. Driving less doesn't cancel the loan. Before counting savings from selling a car, check what you owe, what it could sell for, and how everyone would get around.

Work lunches, clothes, and takeout may cost less. Groceries, utilities, activities, or occasional care may cost more. Being home doesn't mean one person suddenly has time to cook, clean, fix, and handle everything the family used to pay for.

Write down where each estimate came from: a childcare notice, an insurance quote, a recent bill, or a spending change you've tried.

The car does not become maintenance-free because somebody stopped commuting.

A one-income budget example that still comes up short

Let's use a made-up family with two parents. One brings home $5,200 a month; the other brings home $3,000. They're thinking about having the second parent leave paid work.

These are example amounts, not average family costs or a tax estimate. The income figures are after estimated taxes and existing paycheck deductions. We show the extra health-insurance cost as a separate bill. It hasn't also been taken out of the future paycheck.

The family loses $3,000 in monthly take-home pay. The total it needs for spending and savings falls by $1,370:

• $1,600 less for care.
• $220 less for transportation.
• $100 more for groceries.
• $350 more for health coverage.

That leaves the family with $1,630 less breathing room each month: $3,000 minus $1,370.

But it already had $1,150 left in the current plan. After using that room, the new budget is still $480 short.

One number tells you how much the change costs. The other tells you how much more the family needs to make the new budget work.

Finding another $480 would cover the listed bills and savings, with nothing extra left. That still leaves little room for a wrong estimate. If the extra insurance cost turned out to be $600 instead of $350, and groceries reached $1,150 instead of $1,000, the family would be $880 short.

Run your own numbers before deciding what must change. Keep money for irregular expenses such as repairs, renewals, and school costs in the plan. Those bills keep their appointments even when your income changes.

What should you check before leaving a job?

Find out what health insurance would cost

Ask when the old plan ends, what new plans you can use, what you'd pay, and when coverage starts. Look beyond the monthly price, called the premium. Check the deductible, the doctors in the plan's network, and the limit on what you could pay for covered care.

If leaving a job means losing its health coverage, HealthCare.gov says you can qualify to sign up for a Marketplace plan outside the usual enrollment season. That can apply even if you quit. You generally need to apply within 60 days of losing coverage. Check the dates before the old plan ends.

The deadline to join a spouse's work plan may be shorter. The Department of Labor describes a 30-day signup window after a qualifying loss of job-based coverage. It also explains COBRA, which can let you keep job-based coverage for a limited time. You usually pay your old share, the employer's share, and an added fee.

Get the price in writing. The amount coming out of your paycheck now doesn't tell you what a new plan would cost.

If your future paycheck already has the new insurance cost taken out, don't count it again as a bill.

Recheck taxes and childcare benefits

Your tax bill can change when one paycheck stops. Don't assume you'll save a set share of the lost salary. The tax money taken out of each paycheck is called withholding. It's a payment toward your tax bill; the final amount is worked out on your tax return.

If you qualify to use it, the IRS Tax Withholding Estimator can help you check how much federal income tax your job should take out. Check any state income tax too. Run the numbers for the year you leave and for the first full year on one income.

Recheck childcare tax breaks too. For the child and dependent care credit, the IRS generally requires care that lets you work or look for work. Earned-income rules and other conditions also apply. There are special rules for some full-time students and spouses who can't care for themselves.

Ask HR about any childcare benefits through work. Check whether you would still qualify and when the money would be available. Last year's tax refund doesn't get a standing invitation to next year's budget.

Check the other benefits that come with the job

Write down what else would change if you left:

• Retirement money you put in and money your employer adds.
• Credit toward a pension and any dates that affect how much of the employer's retirement money you can keep.
• Life insurance or insurance that helps replace pay if you can't work.
• Paid time off, job training, or other benefits you use.

Ask HR or the person who manages the plan about the rules that apply to you. A smaller paycheck can still come with benefits worth checking before you give notice.

How do you protect both parents' financial future?

A monthly budget can balance while retirement saving quietly falls.

Some retirement money may come out of your pay before it reaches the bank. Money your employer adds won't show up in checking either. List both amounts, then decide how much your family can keep saving after the change.

If you're married and file taxes together, you may still be able to put money in an IRA, a retirement account, when you aren't earning a paycheck. The IRS calls this a spousal IRA arrangement. It uses the couple's qualifying earnings and has yearly limits, income rules, and other conditions. If you qualify, put the planned deposit in your budget. Opening an account doesn't put money in it.

Time away from work covered by Social Security can affect your own retirement benefit. SSA uses your highest 35 years of earnings to calculate that benefit. If you have fewer than 35 years, it counts zeros for the missing years. Check your own earnings record before assuming what a break would cost.

Talk through the day-to-day money decisions too:

• Both adults can see the accounts, bills, and savings.
• Both can use household money and have a say in personal spending.
• You've talked about how bills and care would get covered if either parent couldn't do their usual work.
• You've picked a date to review the plan and discussed returning to paid work if things change.

If you might return to work later, check what it would take. Would you need to renew a license, take a class, or find childcare? Keep up with useful work contacts if you can. Give yourself options without assuming the same job and pay will be waiting.

Family time also has value beyond the paycheck calculation. That's part of deciding what your time is worth. It belongs in the decision alongside the financial consequences.

How can you test living on one income before you commit?

If your circumstances allow, test the proposed budget for two or three months while the job is still there.

Keep paying the bills you still owe. Both parents may still need childcare and a drive to work during the test. Trying to save an entire paycheck can make the plan look harder than it would be after those costs change.

Use a separate practice budget:

1. Write down the take-home pay you'd expect on one income.
2. Track actual household spending.
3. Change only the costs you have good reason to change. Remove care you'd stop paying for, keep occasional care you'd still use, lower the work-travel costs, and add the new insurance cost.
4. Keep money for bills that come less often and the savings you plan to continue.
5. See what would have been left on one income.

For the example family, start with $7,050 in current spending and savings. Subtract $1,600 in care savings and $220 in travel savings. Add $100 for groceries and $350 for insurance. The new total is $5,680. Against $5,200 in income, that's a $480 gap.

That's a practice calculation. You still have to pay the childcare bill during the test.

Use the test to see whether your estimates hold up and the spending changes are ones you can live with. Save what you can after paying current bills. If you're expecting your first baby, the test won't show all the costs ahead. Get estimates for medical bills, feeding, care, and other needs, then update the plan as you learn more.

What if the one-income budget doesn't work yet?

Name the gap first. “We need another $480 a month plus some breathing room” gives you a clearer problem to solve than “We can never do this.”

Look at changes you could actually make: fewer paid hours, a different schedule, a more flexible job, a later start, or lower spending. Count what each change would save and what it would ask of the family.

Be careful with income you hope to earn on the side. Count taxes, costs, work time, and any care you'd need. A full-time remote job still needs time to work. A new business isn't dependable bill money before customers have shown up.

If the bills you must pay already cost more than you bring home, say so. Having bills due before payday is a different problem from not earning enough to cover them.

You can save for a planned break from work. Keep that money separate from emergency savings, decide how much you're willing to use, and pick a date to review the plan. Paying part of the bills from savings is a temporary plan, so be clear about how long it can last. The CFPB explains that the emergency savings you need depend on your situation.

Ask what you would do if the remaining earner lost work or income fell. A plan that needs every month to go perfectly deserves another look.

Common questions about affording a stay-at-home parent

How much does one parent need to earn for the other to stay home?

There isn't one salary that works for every family. Compare take-home pay with your housing, care, debt, insurance, other spending, and savings. A salary before taxes doesn't show what you'd have to spend or what your family needs.

Can I afford to be a stay-at-home mom if childcare takes most of my paycheck?

Possibly, but compare the whole family's numbers. Count the benefits, retirement saving, and future work options that come with the job. Then subtract the care and work-travel costs you'd stop paying. Use the same approach for a stay-at-home dad.

Does choosing one income mean giving up on financial progress?

It depends on your numbers and what matters to your family. You may keep saving, save less for a set time, or decide the change doesn't fit yet. Make the choice clear and review it later. Paid work and caregiving both contribute to a family. Somebody else's household doesn't get to cast the deciding vote.
