Planning a sabbatical budget

A sabbatical is an extended break from work used for travel, learning, caregiving, or recovery. The financial question is simple: how much cash do you need for monthly expenses during the break, and how much must you save each month before you start?

This calculator totals your monthly sabbatical budget, projects growth on existing savings, and solves for the monthly contribution needed to close the gap. For broader lifestyle goals, pair it with the dream come true calculator or the Coast FIRE calculator if you want work optional after the break.

Total fund and future value

The total sabbatical fund equals monthly expenses multiplied by duration in months:

Total Fund=Monthly Expenses×Duration\mathrm{Total\ Fund} = \mathrm{Monthly\ Expenses} \times \mathrm{Duration}

Current savings grow to a future value before the sabbatical begins:

FV=PV×(1+r)n\mathrm{FV} = \mathrm{PV} \times (1 + r)^{n}

Where PVPV is present savings, rr is the monthly return rate, and nn is months until the sabbatical starts. The remaining gap is total fund minus projected savings.

Required monthly savings

To close the gap with equal monthly contributions and compound growth, use the ordinary annuity payment formula:

PMT=FV×r(1+r)n−1\mathrm{PMT} = \frac{\mathrm{FV} \times r}{(1 + r)^{n} - 1}

If the expected return is zero, divide the remaining gap by months until start. For recurring deposits into a growth account, compare assumptions with the investment calculator or the RD calculator.

Worked example

Plan a 6-month sabbatical with $3,500 monthly expenses ($2,500 living, $500 travel, $300 insurance, $200 misc). You have $5,000 saved today, 12 months to prepare, and expect 4% annual return.

  1. Total fund needed: 3,500×6=21,0003{,}500 \times 6 = 21{,}000.
  2. Future value of $5,000 at 4% over 12 months: about $5,204.
  3. Remaining gap: about $15,796.
  4. Required monthly savings: about $1,293 per month for 12 months.

Frequently asked questions

Should I include health insurance in sabbatical costs?
Yes. If you leave employer coverage, budget for individual premiums, out-of-pocket care, and prescriptions. Underestimating healthcare is a common reason sabbaticals run over budget.
What return rate should I use?
Use a conservative yield for money you will spend within a year or two, such as a high-yield savings account or short-term Treasury rate. Higher assumed returns reduce required monthly savings but add market risk if funds are invested in volatile assets.
Does this include taxes on investment growth?
No. The calculator models pretax growth for simplicity. Taxable accounts may owe taxes on interest or realized gains, so keep a small buffer above the calculated target.
What if I already have enough saved?
When projected savings exceed the total fund, required monthly savings drop to zero and the progress bar reflects that you are fully funded based on current balances.
How is savings progress calculated?
Progress compares current savings to the total sabbatical fund before growth. It is a snapshot of how far you are today, not the projected balance at departure.
