Should I quit my high-paying job?
Short answerFour things drive the answer: how much you've already invested, how much your monthly savings drop, whether spending drops with the switch, and how many more years you'd have stayed. Once a substantial share of the target is invested, existing compounding often limits the delay to a few years. Run your own numbers rather than trusting a rule of thumb.
You're asking about a career move, not retirement, and the cost you actually care about is years of your Optional Date. Below: a calculator, a worked example, and the formulas.
Calculator
Model the switch
Type your numbers. Set what you save now, what you'd save after the switch, how your yearly spending changes, and when you'd make the change. The calculator shows both Optional Dates (today's plan and the post-switch plan) and the delay between them.

A big delay. Consider whether spending drops with the job change — that usually shrinks the gap fast.
Two targets Current spending sets the pre-switch target ($2.00M); post-switch spending sets the target the portfolio has to hit from the switch month on ($2.00M). Drop post-switch spending to see how quickly a lower-cost lifestyle closes the gap the pay cut opens.
Assumes a 7% average real return (after inflation) and a 4% withdrawal rate.
What the pay cut actually costs
The delay is proportional to your drop in monthly savings, not to your drop in gross pay. If you save $3,200 a month now and drop to $1,200 in a new role, the calculator adds up the future value of the $2,000 monthly gap and shows how much later that pushes Optional.
Two things soften the blow. Most lower-paying career changes come with a real spending drop. The lifestyle that fits a nonprofit isn't the one that fit the grind. And if you're already substantially funded, compounding keeps working on the existing balance whether you're contributing $3,200, $1,200, or zero. The delay is years, not decades.
The high-cost case is switching early, saving far less, and not cutting spending. Then the delay compounds against you. Slide the "switch happens in" chip on the calculator to see the trade-off shift.

What a real switch costs
Case study — Kim, 52 — illustrative case study, senior tech PM
Kim has $650,000 saved across her 401(k), Roth, and brokerage. She saves $1,800 a month in her senior PM job and spends about $72,000 a year. She's burned out and wants to quit for something lower-key: a mix of teaching and light consulting that would bring in around $1,500 a month.
Balance
$650,000
Monthly save
$1,800
Annual spend
$72,000
New income
$1,500/mo
If Kim stays put: Optional in April 2038, at age 64. The full $1.8M target, funded entirely by her portfolio.
If she quits for the $1,500/mo gig: her portfolio doesn't have to fund the whole $72K anymore. It funds $54K, and the new work covers $18K. Target drops to about $1.4M. Optional lands in October 2034, at age 61. Roughly 3.5 years sooner.
The counter-intuitive part: quitting the high-paying job actually pulls Optional forward, because ongoing income shrinks the target. Every $100/mo of new income means $30,000 less she needs saved. Kim's $1,500 a month is $450,000 off the number.
If she quits for nothing: the target stays at $1.8M and the switch just cuts her contribution to zero. Optional pushes back about 3 years. The difference between "quit for a modest gig" and "quit for zero" is 6 years of Optional, which is why the specific income level matters more than the fact of quitting.

The math
Assumptions and formulas
Same engine as the rest of the app.
Optional Number = Annual Spending ÷ 4% = Annual Spending × 25
Each month, your balance grows and then absorbs the current contribution. Before the switch, that's your current save. After the switch, it's the new save:
ending balance = starting balance × (1 + monthly return)
+ (before switch ? current save : save after switch)
monthly return = (1 + 7%)^(1÷12) − 1 ≈ 0.565%/month
- 7% real (inflation-adjusted) return. Your target stays flat in today's dollars.
- 4% safe withdrawal rate. Fixed on this page; adjustable in the app.
- Post-switch spending is a separate input from current spending. Model a lifestyle drop directly, or leave both equal to hold spending flat.
- The switch is one-time. To model a second switch later, use a layered scenario in the Lab.
- No taxes on withdrawals. See the methodology page for the current limits.
FAQ
What people ask about this
Is there a "you're safe to switch" threshold? Not one you can name in a sentence. The delay depends on four inputs, not one. On many mid-career numbers a modest pay cut without a spending drop adds a few years; on many others it adds much less. Model your case rather than picking a threshold.
What if the new job comes with better benefits? Better employer-paid insurance or transit or meals reduces your current cash outflow, which lets you save more today (a higher "save after switch") or spend less today. Whether your post-Optional spending target drops is a separate question. You're modeling how you'd live once work is optional, which usually doesn't include employer benefits. The calculator has two spending inputs so you can treat these separately.
What if the switch pays more, not less? Then the delay is negative. Optional moves closer. Set "save after switch" higher than "current save" and watch the date pull forward.

Can I work part-time after Optional? →
The softer version. Drop the hours instead of switching to a lower-paid full-time job.
If I save an extra $500 a month, when can I retire? →
The opposite lever. If a pay cut is the fear, more compounding is the antidote.
Can I afford a sabbatical? →
A twelve-month test drive of the change. Much cheaper than a permanent switch.
