Sabbatical & Career Break Cost Calculator
Can I afford 6 months off? What's the recovery timeline?
How This Calculator Works
The visible cost of a sabbatical is the savings you spend while not earning; the real cost adds everything that money and time would have produced if you'd kept working — the paychecks, the retirement contributions, and the compounding on both. This calculator models all of it. You give it your current savings, expected monthly spending during the break, the break's length, your salary and savings rate, and your assumed investment return, and it simulates your wealth month by month through the break and the years after.
Two outputs do most of the work. Net worth impact is the long-run gap between the with-sabbatical and without-sabbatical trajectories — not just what you spent, but what that money would have become by retirement. Recovery time is how many months of normal earning and saving it takes to climb back to where you would have been had the break never happened. Alongside those, the FIRE-date impact translates the same gap into time: how much later financial independence arrives because of the break.
What the model deliberately doesn't decide for you is whether the break is worth it. Sabbaticals can raise later earnings (new skills, a better job, avoided burnout) or lower them (a rusty network, a salary reset), and those second-order effects are yours to judge. What the calculator guarantees is that you make that judgment against the true price tag rather than the sticker price.
Worked Example
Say you're 35, earning $110,000 with a 15% savings rate, holding $80,000 in savings, and considering a 12-month break at $4,000 a month of spending. The direct drain is $48,000 of expenses plus a year of missed saving — but the projection shows the with-break line staying below the no-break line long after you return to work, because the spent-and-unsaved dollars miss out on decades of compounding. Depending on your return assumption, the gap at retirement is typically a much larger number than the $48,000 you actually spent.
Shorten the same break to 6 months, or cut break spending to $3,000 by traveling cheaply or subletting, and the recovery time drops noticeably — the calculator makes those trade-offs concrete. Many people discover the second lever matters more than they expected: the spending rate during the break often moves the long-run cost as much as the break's length does.
Frequently Asked Questions
How much money should I save before taking a sabbatical?
A workable floor is your full break budget — monthly spending times months off — plus a re-entry buffer of several months' expenses in case the return to work takes longer than planned, all without touching your regular emergency fund. The calculator's depletion figure shows exactly what your planned break consumes; if that number would leave your remaining savings uncomfortably thin, the break budget, the duration, or the start date needs to move.
What does a career break really cost compared to what I spend?
Usually a multiple of the cash outlay. The full cost stacks the spending during the break, the paychecks not earned, the retirement contributions not made, and the compounding all of that forgoes over the decades that follow. That's why the calculator reports net worth impact at retirement rather than just totaling your break expenses — the sticker price understates the true price, and the gap grows with your time horizon.
Does a sabbatical delay financial independence or retirement?
Mechanically yes — pausing contributions and spending savings moves the date at which your assets can sustain you. The calculator quantifies the delay as its FIRE-impact figure rather than leaving it abstract. Whether the delay is acceptable is a values question: many people willingly trade a year of retirement timing for a year of life now, but it's a better trade when you've seen the actual size of it.
Should I keep investing during a career break?
Money already invested should generally stay invested — the model assumes your existing balances keep compounding, and selling investments to fund a break adds taxes and sequence risk to the cost. New contributions usually pause, since the break budget consumes your cash flow. What you should protect if at all possible is the emergency fund: a break that ends with zero buffer converts any re-entry delay into debt.
How do health insurance and benefits work during a sabbatical?
If your employer grants a formal sabbatical, benefits sometimes continue — that's worth negotiating explicitly. If you resign, you'll typically bridge coverage through continuation options like COBRA or a marketplace plan, and the premium belongs in your break budget as a real line item; it's one of the most commonly forgotten costs. Factor it into the monthly spending figure you give the calculator rather than treating it as incidental.
The model behind this calculator
spec v1.0.0 · 250 open casesThis calculator runs a published model: its inputs, formulas, assumptions, and exclusions are documented in a versioned specification, and it is Concordance-tested — an independent second implementation, built from that spec alone, must agree with it on 250 open test cases before any change ships. The same model is callable by AI assistants and developers.
