Career Break Financial Impact Calculator
A 12-month career break has hidden costs beyond lost salary: missed 401(k) matching, halted equity vesting, gap in Social Security earnings record, lost employer healthcare. Cumulative impact often 1.5-2x the gross lost wages when retirement contribution shortfalls are projected to age 65.
Beyond Lost Wages
Three hidden costs people miss: (1) 401(k) match (typically $6-15K/yr) — compounds to 5-10x at retirement. (2) Equity vesting halted — anything not yet vested at break start is forfeited. (3) Health insurance gap — COBRA $1,400-1,800/mo for family is 2-3x what employer paid. Add 401(k) match growth to age 65 and you double or triple direct lost wages.
Social Security Earnings Record
SS calculates benefits using highest 35 years of indexed earnings. A 12-month career break in mid-career often replaces an earlier lower-earning year — no SS impact. Career break in your late 40s-50s (peak earning years) likely replaces a top-35 year — meaningful lifetime benefit reduction. Check SSA.gov earnings record before planning extended break in high-earning years.
Mitigation Strategies
Three plays: (1) Max-fund 401(k) and HSA before break — uses Roth conversion ladder for early withdrawal flexibility. (2) Negotiate keeping equity vesting active via consulting arrangement during break. (3) Buy 18-month COBRA if available — locks employer rate. (4) Time break to AVOID peak earning years 50-58. Many late-career breaks happen at peak earnings — worst possible timing for SS calculation.
