How much should you actually save before quitting — a tech worker's real budget breakdown

The standard advice is six months of expenses. It's not wrong as a starting point — it's wrong because it treats "expenses" and "six months" as fixed quantities, when in most tech worker transitions, neither of them is.

What follows is a more honest budget breakdown: the line items that standard runway advice skips, the costs that consistently catch people off guard, and a framework for arriving at the real number — which is usually larger than people have assumed, but also more knowable than it feels from a distance.

The problem with "six months of expenses"

The phrase assumes your post-exit expenses will look like your pre-exit expenses. For most tech workers, they won't — and the gap runs in both directions. Some costs go down when the job goes. Others go up, sometimes significantly. Treating your current monthly spend as the relevant figure produces a calculation that's wrong in two directions: it overestimates in some categories and underestimates in others, with the underestimates concentrated in the areas most likely to create real problems at exactly the moment you can least afford them.

The other assumption built into "six months" is duration. Six months to do what? The financial requirement for six months of active job-searching in a sector where your skills are in demand is a different calculation from six months of building a freelance practice (which takes longer to generate stable income than most plans allow for), which is different again from six months of genuine decompression before deciding anything (which requires the full burn rate, with nothing to offset it). The duration multiplier matters as much as the monthly rate, and most people settle on "six months" without interrogating why that number, for their specific plan, is the right one.

What actually changes in your spending

The first move is to separate what you spend now from what you'll spend after you leave. These are different columns, and the items don't map neatly from one to the other.

Job-attached spending is larger than most people realise until they audit it specifically. Commuting costs — fuel, transit passes, parking, tolls — stop or reduce sharply. Work clothing and dry cleaning, which tech workers often underestimate because the amounts are individually small, accumulate to meaningful monthly figures over a year. The decompression spending that high-pressure jobs generate — the restaurant meals that are really about not having the energy to cook, the online shopping at 11pm, the Deliveroo orders, the gym membership you use as stress management — often represents ten to twenty percent of total monthly outgoings and largely disappears when the pressure does. Some of it shifts to different categories during the transition, but the amount usually drops, sometimes significantly.

What typically goes up is where people get caught. Health insurance is the largest and most consistently underestimated increase for US-based workers. If you've been on employer-sponsored coverage, you've been shielded from the actual market rate by your employer's group contribution. Individual market rates for a 35-year-old in a major US city typically run $500–$900 per month for a mid-tier plan, before deductibles. With a family, that figure can reach $1,400–$2,000 per month. This is not a rounding error. It's often the single largest new cost in a transition and it warrants a specific quoted figure, from your actual marketplace, not an approximation from a friend who left three years ago under different circumstances.

Tax treatment is the second major shift. As an employee, income tax is withheld before you see the money, which creates an invisible affordability that vanishes the moment you're responsible for paying it quarterly. Self-employed people and contractors are often surprised by the size of their first estimated tax payment — not because they weren't earning, but because they'd been mentally treating gross income as available income. Budget explicitly for this from month one. A rough provision of 25 to 30 percent of expected self-employment income, held separately, is the right order of magnitude depending on your jurisdiction.

Professional costs that were invisible as an employee also become visible quickly: accountant fees (necessary and genuinely worth paying — don't navigate self-employment tax alone), professional indemnity insurance that some clients require before signing contracts, software and tooling you need to work independently. Individually modest. Collectively worth a dedicated budget line.

A real breakdown by category

Here's a worked example for a single tech worker in a high cost-of-living US city, leaving a $175,000 base salary role. The numbers are illustrative but calibrated to what's actually typical rather than what looks tidy on a slide.

Housing: Unchanged for the transition period, assuming no immediate move. $2,800 per month rent or equivalent mortgage carry. This is often the biggest fixed cost and has the least flexibility in the short term — factor in whether yours will change, but don't build a transition plan that depends on housing cost reduction that isn't confirmed.

Food and household: Likely down slightly from current spending once work-attached food costs are removed. Budget $600–$800 per month, adjusted to your actual three-month average from statements, not from memory.

Health insurance: New and significant. Look up your specific figure on healthcare.gov or your state's marketplace — for this example, an individual silver-tier plan in a major metro: $680 per month. Do not estimate this. Look it up before you hand in your notice.

Transportation: Down from current if you were commuting. Budget $200 per month, less if the commute was expensive and is now gone entirely.

Phone, utilities, subscriptions: Roughly unchanged, minus the subscriptions you've been meaning to cancel for two years. Do the audit before you leave. $300 per month after the audit, $450 before it.

Tax provision: If you'll be freelancing or consulting, set aside 28 percent of expected self-employment earnings into a separate account from the first payment. Do not commingle this with spending money. The quarterly payment arrives whether you're ready for it or not.

Professional and administrative costs: Accountant, professional insurance, software, any relevant professional memberships. $350 per month averaged over the year, with a spike in the first year as you set things up.

Contingency: $400 per month. Transitions reliably produce unexpected costs — a dental bill, a car repair, a course that turns out to be genuinely worthwhile. Having a specific contingency line prevents these from derailing the overall model.

Total for this person: approximately $5,330 per month as a base burn rate. At six months, that's $32,000. This is less than many tech workers assume when they think "six months of my current lifestyle" — because job-attached spending goes away — and more than others assume when they're trying to reassure themselves. The point is to arrive at the actual figure rather than one that makes the decision easier or harder than it needs to be.

The duration question: how many months do you actually need?

The honest answer is specific to your plan, not to a standard number.

Active job search, similar role: In a normal hiring market, three to four months is the realistic median from resignation to first paycheque in a comparable role. Add a month's buffer for a slow market or a senior level where there are fewer openings. Total runway needed: four to five months at your post-exit burn rate, not six by default.

Career pivot to a different sector: Considerably longer. The search takes longer because your skills need translating; the hiring process is less predictable; and the ramp-up in a new sector often involves a period of reduced income before anything stabilises. Six to nine months is a more honest target, and the higher end applies if the pivot involves significant retraining.

Freelance or consulting ramp-up: Eight to twelve months is realistic for the income to stabilise, not because work doesn't come in but because it comes in unevenly. First-year freelance income for most former tech employees looks like nothing, then one engagement, then a gap, then two at once. The irregularity requires more buffer than average monthly burn suggests, because the dry months arrive unpredictably.

Full decompression, no plan yet: Whatever duration you're considering, give yourself more than you think you need and calculate the full cost at your actual post-exit burn rate, not your current one. Burnout recovery takes longer than most people model. The value of having time to think clearly about what comes next is real, and it requires the financial space to think without the anxiety of a dwindling account shaping every conclusion.

The psychology of building toward the number

There is a specific experience that comes with saving toward a departure you haven't announced and can't yet make. Every month you transfer money to the exit fund, the departure becomes slightly more real — and more real tends to mean more frightening, not less. The progress that should feel like growing freedom sometimes arrives as a new category of worry: I'm actually going to do this.

Treat the saving as slow deciding, because that's what it is. Every month you add to the fund, you're not quite committing but you're moving toward commitment in a way that's psychologically real even if it's practically reversible. The anxiety that comes with growing clarity is expected and temporary. What it doesn't mean is that the direction is wrong.

When you hit the number: pause. Check whether you're leaving because you've decided to leave, or because you've saved enough not to have to stay. Those are similar things, but not identical. The exit fund creates the option. The decision to exercise it is separate and worth being deliberate about.

The freedom number framework is a useful companion if you want to think about what the number is actually for, not just how to calculate it. The financial fears piece addresses the anxiety before the arithmetic, which is often the more useful starting point. And the runway thinking piece covers the psychological preparation alongside the financial, because the number is only half of what you're actually building toward.
