Can you really afford six months off?
The six months you plan are the easy part. The real risk lives in the months you cannot schedule: how long the job search runs when you come back, and what the next offer pays. A static budget hides that risk. A simulation shows it.

After you install, this is the model to open.
Can I Afford a Sabbatical?
- In your spreadsheet, click the Sortia icon in the strip of icons down the right-hand edge. No strip? Click the arrow at the bottom-right to open it. You can also use Extensions, then Sortia, then Open Sortia.
- Click Start from a template and put that name in the search box.
- Pick the card with that name and click Load this template. It arrives on a new tab with real numbers already in it.
This one runs on a Pro engine, and every free install includes five full-quality runs on your own numbers, shared across all five Pro engines rather than five for each. After that, Pro is $199/year.
The answer
One click walks your cash month by month through 10,000 versions of the break and reports where the low point lands.
- Chance you never breach the buffer
- 78% over 24 months
- Lowest balance in the plan case
- $19,500 vs the $10,000 floor
- Longest 90%-safe sabbatical
- 4 months longest break with >=90% odds of staying solvent
- Rebuild time in the plan case
- 20 months back to $60,000
At these defaults a 6-month break clears the floor in about 78% of trials, which means roughly a 1-in-5 chance your balance dips below $10,000 before the next paycheck. The plan case looks comfortable with a $19,500 trough, but a slow search stacked on a higher burn quietly erases it. If you want 90% confidence, cap the break at 4 months or grow the pile before you go.
The model
Start with $60,000 saved and a $10,000 floor you refuse to cross, then let the three things you cannot control vary.
| Cash savings today | $60,000 |
| Safety buffer (never go below) | $10,000 |
| Sabbatical length | 6 months |
| Monthly spend while off work | $4,500 avg, sd $600 (uncertain) |
| Job search after return | 1 – 3 – 8 months (uncertain) |
| Take-home pay before leaving | $7,000 / month |
| Salary change on return | -15% – 0% – +10% (uncertain) |
| Monthly spend after return | $5,000 |
Once it is in your sheet
- The model arrives with real numbers in it and runs as it stands, so you can press the button first and understand it second.
- Change the numbers to yours. The sheet marks which cells are inputs and which hold formulas, and most labels carry a note explaining the row.
- Press the run button at the bottom of the panel. It is labeled for the tool you are in, and the result lands on its own tab, with a written reading of it beside the figures.
