Micro-Retirement Simulator
Model career breaks and see how they affect your path to financial independence
About Detour
Traditional retirement calculators assume you work continuously from 25 to 65. But life is not linear. This simulator lets you model work periods and break periods, showing exactly how sabbaticals, gap years, career pivots, and travel affect your long-term wealth. Add break periods to your timeline and see the real financial impact. Use it to plan a year off, compare scenarios, or decide if that career break is worth the cost. The numbers help you make informed choices about work-life balance and financial independence. Use the Micro-Retirement Simulator to get a clear result you can act on right away. This calculator is designed to be practical, fast, and easy to use on any device.
How Income, Savings, and Expenses Affect Your Portfolio
The portfolio balance changes only through Savings (contributions), Expenses (withdrawals during breaks or retirement), and Investment Returns. Income does not go directly into the portfolio; only the portion you save does.
Example: $80,000 income, $16,000 savings (20%), $50,000 expenses
→ $80,000 − $16,000 − $50,000 = $14,000 unaccounted for
That $14,000 (taxes, discretionary spending, etc.) is implicitly treated as spent and never enters the portfolio.
Summary: The model only adds to or subtracts from your portfolio via Savings (contributions) and Expenses (withdrawals). The rest of your income is implicitly assumed spent and does not affect the portfolio balance.

Career Breaks
Add sabbaticals, travel years, career pivots, or parental leave. Use 40.5 for 6 months into age 40. During breaks you withdraw from your portfolio. Plan to keep break funds in accessible accounts (taxable brokerage, Roth contributions) to avoid early withdrawal penalties.

The Formula
How to Calculate Manually
- 1
Enter your current age, income, savings, and retirement goals
- 2
Set your investment contribution rate during work periods
- 3
Add break periods (sabbaticals, travel, career pivots) with age ranges and expenses
- 4
View projections: retirement age, net worth at 65, and break impact summary
- 5
Compare your scenario to continuous work (no breaks)
Examples
1-year break at 34, $30k expenses
Typically delays retirement by 2-3 years and reduces net worth at 65 by $150-250k
6-month break every 5 years
Six sabbaticals over a career may add 3-4 years to retirement age
2-year parental leave at 30
Lost contributions + withdrawals can cost $200-400k in retirement dollars
FAQ
💡 Tips
- •During breaks, you withdraw from this portfolio. Plan to keep break funds in accessible accounts (taxable brokerage, Roth contributions, emergency fund) to avoid early withdrawal penalties on retirement accounts.
- •Build a break fund in cash/bonds to avoid selling investments in a downturn
- •Reduce expenses during breaks when possible to limit portfolio drawdown
- •Consider part-time or freelance income during breaks to offset costs
- •Later breaks cost less in opportunity cost (fewer years for money to grow)
🎉 Fun Facts
- •Traditional calculators assume continuous employment from 25-65, but millennials and Gen Z average 12+ job changes and 2-3 career pivots in a lifetime.
- •A 1-year break at 30 can cost $200k+ in retirement dollars when you account for lost contributions and their 35-year compound growth.
- •Taking a break during a bear market costs more than during a bull market because you sell investments when they are down to fund living expenses.
- •The 4% rule (25x expenses) still applies, but career breaks push your 'retirement number' further out due to fewer contribution years.
- •Many people who take strategic sabbaticals report higher post-break salaries due to new skills, clarity, and negotiation leverage.
