A single-income household budget after a job loss has a different problem than a simple pay cut. Rent, insurance and utilities don’t shrink because income did, so cutting everything proportionally usually isn’t enough. Below is a worked example with assumed numbers, plus the official rules on health coverage.
Build the Cushion Before You Need It
If you can see the transition coming, my suggestion is to build a larger cushion than usual, since it needs to cover the adjustment period itself. I don’t have an official target to cite, so choose a number of months of expenses based on how long you expect the transition to take. If it’s planned, an automatic transfer from both paychecks into a separate account builds it quietly.
A Real Transition, Worked Through

All figures here are assumed. Say your household brings in $8,000 a month combined, and after the transition one income of $4,500 remains.
The gap: $3,500 a month.
Step 1: Redirect what disappears. Commuting, work clothes and some childcare costs may shrink. Assume that’s $900 a month. The gap becomes $2,600.
Step 2: Trim variable costs. Groceries and entertainment have flexibility. Assume a $600 trim. The gap becomes $2,000.
Step 3: Revisit fixed costs. Assume downsizing a vehicle or a refinance closes another $500 to $800 a month. The gap narrows to $1,200 to $1,500.
The rest would come from savings or a temporarily lower savings rate until income recovers. In my view, seeing the remaining number is more useful than a vague sense of being stretched.
If This Is Happening Because of a Job Loss, Health Insurance Changes Everything

A planned career change and a layoff can look the same on a spreadsheet, but a layoff can end your employer health coverage.
What COBRA Involves
According to the U.S. Department of Labor, COBRA continuation coverage generally lasts up to 18 months after termination (other than for gross misconduct) or reduced hours, and you usually pay the full premium: your former share, the employer’s former contribution, and 2 percent. You have 60 days to elect, counted from the later of when your coverage ends or when the election notice is provided, and 45 days after electing to make the first payment.
The Marketplace Alternative
HealthCare.gov says you can apply for a Marketplace plan within 60 days after losing job-based coverage, whether you quit or were fired, with coverage beginning as early as the first day of the month after you lose coverage. It says you may get premium tax credits and extra savings based on income, and you may qualify for Medicaid or CHIP. It also says that if you’ve already enrolled in COBRA, you may be able to switch to a Marketplace plan.
Medicaid
HealthCare.gov explains that in states that expanded Medicaid you can qualify based on income alone, at 133% of the federal poverty level (138% in practice with the income disregard). The 2026 HHS poverty guideline for one person in the contiguous states is $15,960, so 138% works out to about $22,025 a year. States that haven’t expanded use different rules.
Compare Before the Deadline
In my view, a side-by-side comparison of COBRA and Marketplace costs for your own household is worth doing before either deadline passes, because both have 60-day windows.
Moves That Can Help
- Build the full budget before the transition, if you can.
- Pay yourself first. Treat savings as the first line.
- Redirect freed-up costs. Commuting and childcare savings can go to savings or debt.
- Separate fixed from variable spending. Variable costs are usually the easier ones to adjust.
- Budget irregular annual expenses monthly. Divide the yearly cost by 12.
- Review subscriptions. Cancel or downgrade what you don’t use.
- Automate what you can.
- Track the first month closely and adjust to real numbers.
- Revisit the plan monthly at first. My suggestion is quarterly once things settle.
What Unemployment Benefits Mean for Taxes
A Congressional Research Service summary says unemployment insurance benefits have been fully taxable as federal income since 1986, that recipients can elect federal withholding (10% of the gross payment for regular benefits), and that states send Form 1099-G by January 31 each year.
Matching Strategies to Your Situation
- “The transition hasn’t happened yet.” → Start building a cushion now.
- “We just dropped to one income.” → Track spending for the first full month against real numbers.
- “One of us is home now.” → Redirect freed-up commuting or childcare money.
- “This was a layoff.” → Compare COBRA and Marketplace within the 60-day windows.
- “We’re still stretched after a few months.” → Revisit fixed versus variable costs.
- “Annual bills keep surprising us.” → Divide the yearly total by 12.
Single-Income Budgeting: Questions Answered
How big should our emergency fund be? There’s no official figure. My suggestion is a larger cushion than usual, sized to how long you expect the adjustment to take.
Is COBRA the only option after a layoff? No. HealthCare.gov lists Marketplace plans as the other main option, and COBRA can be switched out for a Marketplace plan.
Are unemployment benefits taxable? Yes, as federal income, per the CRS summary.
How often should we revisit the budget? Monthly at first, in my view.
Where I’d Start This Week
If the transition is ahead, open a dedicated account and automate a transfer from both paychecks. If you’ve already switched, track every dollar for a month. If a layoff ended your coverage, note the dates on your COBRA election notice and compare it with a Marketplace plan.
