Career Break Impact Calculator
How much does a career break cost your retirement? Time out for caregiving, parenting, or sabbatical means lost contributions, lost employer match, and decades of foregone compound growth. See the numbers.
Example: $500/mo + 50% match, 2 years off, 7% return, 25 years to retirement
Lost contributions
$12,000
Lost employer match
$6,000
Lost at retirement
$104,536.55
Opportunity cost
$104,536.55
2 years off = $12,000 in lost contributions + $6,000 match. With 7% growth over 25 years to retirement: $104,536.55 less in your nest egg.

Frequently asked questions
How much does a career break cost my retirement?
You lose contributions, employer match, and decades of compound growth. At $500/month + 50% match, 2 years off = $18,000 in lost contributions. At 7% for 25 years to retirement, that becomes ~$100,000 less in your nest egg. The calculator shows the exact impact.
Should I contribute to an IRA during a career break?
If you have taxable income (spouse, part-time work, freelance), you can contribute to a traditional or Roth IRA. Even $200/month helps. If you have no income, you generally cannot contribute to an IRA. A spousal IRA may apply if married filing jointly.
How do I catch up after time off work?
Increase contribution rate when you return. 50+ can use catch-up contributions ($7,500 extra for 401k in 2024). Consider maxing out for a few years. The lost balance is real—aggressive saving post-return can partially offset it.
Does a 2-year break really matter?
Yes. Two years of $500/month + 50% match = $18,000 not contributed. At 7% for 25 years, that's ~$100,000 less at retirement. The earlier the break, the more compounding you lose. The calculator quantifies it for your situation.
Does this include the salary I lose during the break?
No. The engine takes five inputs only: monthly retirement contribution, employer match percent, break length, expected return, and years from the end of the break to retirement. Lost wages, missed raises, vesting schedules, and pension or social insurance credits are all outside the model. Read the output as the retirement-account cost of the break in isolation, and budget for the missing paycheck separately - the two are different decisions on different timescales.
Why did entering 0% return give me a 7% result?
The engine treats zero and blank entries as missing values and substitutes defaults before clamping: 2 years for break length, 7% for return, 25 for years to retirement. The clamps that follow are 0.5-20 years, 0-15%, and 0-50 years. So a 0% return cannot be modelled through that field. To see the outcome with no growth at all, read the lost contributions and lost employer match lines instead - neither involves compounding.
How much of the shortfall is missed compounding rather than missed deposits?
Most of it. In the worked example, $12,000 of contributions plus $6,000 of match - $18,000 of actual deposits - project to $104,536.55 at retirement. That leaves $86,536.55, about 83% of the total, as growth that never happened, and makes the projection roughly 5.8 times the cash. The earlier in a career the break falls, the further that ratio tilts toward growth, because the lump sum has longer to compound.
My employer matches 50% of the first 6% of pay. What do I enter?
The match field multiplies your entire contribution, so it fits a flat match cleanly and a capped one only after adjustment. Work out the dollars your employer would actually have added each month, divide that by your monthly contribution, and enter the result as the percentage. Contributions above the cap earn no match, so leaving the headline 50% in place while contributing past the cap will overstate the match line and the projected shortfall.

How the math works
lib/calculators/careerBreakImpact.ts models one thing: the retirement deposits you do not make while out of work, and the growth those deposits would have produced. Monthly match = monthly contribution x match percent, so a 50% match on $500 adds $250 and the deposit modelled is $750 a month. Lost contributions ($500 x 12 x 2 = $12,000 in the page's example) and lost employer match ($6,000) are reported as separate lines - the first is your money only, not the combined figure. The $750 is then run through a future-value-of-annuity formula compounded monthly across the break, and that end-of-break lump sum is compounded annually - (1 + 7%) to the 25th power in the example - to the retirement date, giving $104,536.55. Opportunity cost is that same number under a second label. Inputs are clamped: break 0.5-20 years, return 0-15%, years to retirement 0-50. Zero or blank entries fall back to defaults of 2 years, 7% and 25 years.
Using the result
Read the two halves of the result differently. The contribution and match lines are cash you can consciously replace; the retirement figure is a projection that swings hard with the return you assume. In the page's example, $86,536.55 of the $104,536.55 - roughly 83% - is foregone growth rather than foregone cash, so the estimate is only as good as the 7% you entered. Run 5% and 9% from the presets before treating any single figure as a target. The model ignores salary, vesting schedules, and state or federal pension credits, so read it as a floor on the cost of a break, not the whole cost. If you plan to return to work, the actionable output is the contribution increase needed afterwards: compare the shortfall against what a higher deferral rate would rebuild.
