Quitting to Caregive for 2 Years Can Cost a $65K Earner Six Figures — Not Just the Salary

Lost wages are the part everyone sees coming. We ran a $65,000/year earner through the Social Security Administration’s own bend-point formula for a 2-year caregiving leave, and the two costs that don’t show up on a single paycheck — the lost employer retirement match and a permanently lower Social Security check — turned out to be the bigger story.

Three costs, only one of them visible

Cost component What it is Why it’s easy to miss
Lost wages Salary given up during the leave The obvious, immediate cost
Lost employer match 401(k) match not received, compounded to retirement Invisible until retirement projections are run
Lower Social Security Permanently reduced monthly benefit for the rest of retirement Doesn’t show up until decades later, when it’s too late to change course

The first cost is a number people plan around. The second and third are the ones that turn a “I’ll take a year or two off” decision into a much larger lifetime number than anyone budgeted for.

Why the Social Security hit is bigger than it looks

Social Security’s Primary Insurance Amount (PIA) formula averages your indexed monthly earnings across your 35 highest-earning years. If a caregiving leave falls within what would otherwise be one of those 35 years — which it usually does for anyone early or mid-career — the $0 earnings during the leave directly dilute that average.

The formula itself, per the SSA’s 2025 bend points: 90% of the first $1,226 of average indexed monthly earnings (AIME), 32% of the amount between $1,226 and $7,391, and 15% above that. Because the formula is progressive — the replacement rate drops as income rises — a dollar of reduced AIME costs a lower earner a larger percentage of their eventual benefit than it costs a higher earner. Caregiving leave, in other words, is regressive in its Social Security impact.

Running the actual numbers

For a $65,000/year earner taking a 2-year leave, with a 4% employer 401(k) match, 7% assumed investment return, 20 years to retirement, and 20 years of expected benefit collection:

  • Lost wages: $130,000 — direct, no growth applied, since the money never existed to invest.
  • Lost employer match, compounded to retirement: a multi-thousand-dollar loss that grows for the remaining working years before retirement, on top of the wages themselves.
  • Lower monthly Social Security check: a permanent reduction that repeats every single month of retirement — easily tens of thousands of dollars over a 20-year collection period once totaled.

The exact totals depend on your specific salary, years of leave, and retirement horizon — the point isn’t the specific dollar figure, it’s that the wages alone understate the true cost by a wide margin.

Where this framework breaks

  • You already have 35 high-earning years banked. Later in a long career, leave years might not displace a top-35 year at all — the real Social Security hit could be much smaller than the worst-case estimate above.
  • Partial, reduced-hours work isn’t the same math. Dropping to part-time instead of fully quitting changes every number proportionally, but with thresholds (a reduced-hours employee may lose 401(k) match eligibility entirely at some employers, for instance) that don’t scale linearly.
  • A spousal Social Security benefit can offset part of it. Spousal benefits (up to 50% of a spouse’s PIA) can partially cushion an individual’s own reduced benefit — not modeled in a single-earner calculation.

What to actually do

  1. Run your real numbers before deciding to leave a job for caregiving — the total is almost always larger than the salary alone suggests.
  2. Check whether your employer offers unpaid, job-protected FMLA leave instead of a resignation — it preserves both the job and retirement-match continuity for a defined period.
  3. Check your state for a paid family leave program with caregiving provisions; a growing number now offer partial wage replacement.
  4. If reduced hours are an option instead of a full exit, model that scenario — the Social Security and match hits shrink roughly proportionally, not to zero.
  5. If you do take the leave, contribute to an IRA during that period if you have any income at all — it won’t offset the Social Security hit, but it rebuilds part of the retirement gap.
