What’s driving this
During a 1-year sabbatical, you have no earned income. With spending at $60,000 per year, about $60,000 is withdrawn from your portfolio over the break. You also miss $40,000 in contributions you would have made while working. After returning to work, your portfolio recovers to its pre-sabbatical level in about 0.9 years. The long-term gap is driven by compounding on the lost period, not the sabbatical itself.
Why sabbaticals are worth modeling
Many people assume taking time off permanently damages their finances. In reality, the impact is often smaller than expected because your existing portfolio continues compounding even while you’re not working. The biggest cost is usually lost contributions, not the time itself.
Understanding the real numbers helps you make confident decisions. A sabbatical, career break, or extended parental leave is a life decision, not just a financial one. This simulator quantifies the tradeoff so you can weigh it against the personal value of time off.
Compounding doesn’t stop when you do
Your invested assets continue growing at the expected return rate during a sabbatical. If your portfolio is large relative to your spending, the market growth alone may offset most or all of the sabbatical cost.
- Immediate cost — Cash withdrawn from the portfolio during the break. Depends on the gap between sabbatical income and spending.
- Lost contributions — Savings you would have added to the portfolio while working. Often the larger factor.
- Opportunity cost — The compounding growth those lost contributions would have generated over the remaining time horizon.
The chart above shows how both scenarios play out. The gap between the lines is the all-in cost, including compounding effects.
