Can I Afford to Quit My Job? A Runway Calculator and Checklist
Short answer: can I afford to quit my job? You can if your savings cover your essential costs for long enough to find new income, and your runway is your savings divided by your monthly costs. With $24,000 saved and $3,800 of monthly essentials including health insurance, your runway is about 6.3 months. Earning $1,500 a month from part-time work stretches that to about 10.4 months.
Key takeaways
- Runway = usable savings divided by monthly spending you cannot avoid. It tells you how many months you can last with no income.
- Count health insurance. Losing employer coverage is one of the biggest new costs when you quit.
- Any income during the gap lengthens the runway quickly: $1,500 a month moves 6.3 months to 10.4.
- Common reference points: under 3 months is thin, 3 to 6 is tight, and 6 to 12 or more gives room. They are not rules.
How do you calculate your runway?
- Add up usable savings. Cash and easy-to-sell savings. Leave out retirement accounts (early withdrawals can cost tax and a penalty) and money set aside for taxes.
- Add up essential monthly costs. Housing, utilities, food, insurance, transport, minimum debt payments and phone. Leave out spending you can cut to zero.
- Add the new costs of quitting. Health insurance, and any benefits you lose.
- Subtract any income you will have. Part-time work, a partner's pay or freelance projects.
- Divide. Savings divided by (costs minus income) gives the number of months.
How long would your savings last?
Months of runway by savings and monthly essential costs, with no income:
| Usable savings | At $3,000 a month | At $4,000 a month | At $5,000 a month |
|---|---|---|---|
| $10,000 | 3.3 months | 2.5 months | 2.0 months |
| $20,000 | 6.7 months | 5.0 months | 4.0 months |
| $30,000 | 10.0 months | 7.5 months | 6.0 months |
| $50,000 | 16.7 months | 12.5 months | 10.0 months |
Compare this with the time a job search usually takes in your field. Many people find a new role in a few months, but it can take much longer in a slow market or a senior role, so plan for the slow case.
What does a worked example look like?
Take someone with $24,000 of usable savings. Their essential costs are $3,200 a month, plus $600 for a private health plan, a total of $3,800.
| Scenario | Monthly gap | Runway |
|---|---|---|
| No income | $3,800 | 6.3 months |
| $1,500 a month of part-time work | $2,300 | 10.4 months |
| $2,500 a month of freelance work | $1,300 | 18.5 months |
The same savings last three times as long with $2,500 of income. That is why a bridge, such as part-time work or a first client signed before you leave, is the strongest lever.
What about health insurance?
If your health cover comes from your employer, leaving usually ends it. Options include continuing it through COBRA, where you generally pay the full premium and may pay more than you expected, a marketplace plan, or a partner's plan. Losing job-based coverage usually opens a limited window to join a marketplace plan, so check the deadline. Price the options before you resign and include the cost in your essentials. See IRS.gov for tax rules, and the healthcare marketplace for plans.
What else belongs on the checklist?
- Unemployment benefits. They are generally not available if you quit voluntarily, though rules vary by state and there are exceptions. Do not count on them.
- Unvested pay. Bonuses, equity or match that you would lose by leaving. A few more months can be worth a lot.
- Your 401(k). See what to do with your 401(k) when you change jobs.
- Debt payments. They continue with no pay. See your debt-to-income ratio.
- Self-employment taxes, if you freelance. See quarterly estimated taxes.
- A partner or dependants, whose costs and income are part of the answer.
How can you make it safer?
- Build the fund first. See how to build an emergency fund and the emergency fund for freelancers.
- Cut costs now to see if you can live on less. See how to lower your monthly bills.
- Line up income before you leave, even a small amount. See how to start a side income.
- Set a decision date and a stop-loss: the month by which, if income is below a target, you look for a job again.

Frequently asked questions
How do I know if I can afford to quit my job?
Divide your usable savings by your monthly essential costs, including health insurance, minus any income you will have. With $24,000 saved and $3,800 of costs, your runway is about 6.3 months.
How many months of savings do I need before quitting?
A common reference is at least six months of essential costs, with more if your field hires slowly. Under three months is thin. Any bridge income, such as $1,500 a month, lengthens the runway quickly.
What happens to my health insurance if I quit?
Employer coverage usually ends. You can often continue it through COBRA by paying the full premium, buy a marketplace plan, or join a partner's plan. Losing job-based cover usually opens a limited window to enrol, so check the deadline.
Can I get unemployment if I quit my job?
Generally not if you leave voluntarily, though rules vary by state and there are exceptions, such as unsafe conditions. Check your state's rules before you resign, and do not rely on benefits in your plan.
Should I quit before I have another job lined up?
It depends on your runway, your field and your costs. Having a new job or first clients lined up is safer. If you do leave first, make sure the runway covers the slow case.
