Can I Afford to Retire Early? What the Numbers Show

What Three Ways Does Early Retirement Compound Against the Math?

Retiring at 57 versus 62 — a five-year difference — creates three compounding headwinds:

1. Five fewer years of contributions: at $20,000/year in savings, plus typical employer matching, plus investment returns, that's potentially $150,000-$200,000 in foregone portfolio growth.

2. Five additional withdrawal years: a portfolio supporting 35 years of retirement rather than 30 faces meaningfully different depletion risk. Historical data shows success rates dropping approximately 8-15% for each 5-year extension of retirement duration.

3. Social Security gap: retiring at 57 means a 10-13 year gap before any Social Security income. That entire period runs on portfolio withdrawals — at the highest-risk sequence-of-returns phase (early in retirement).

What Does the Healthcare Bridge Really Cost in Early Retirement?

For early retirees, pre-Medicare healthcare is a cost that is consistently underestimated in planning analyses.

ACA marketplace premiums for a couple aged 58 with no marketplace subsidy typically run $1,400-$2,400/month depending on state and coverage level. Over 7 years to Medicare eligibility, that's $117,600-$201,600 in cumulative premiums — plus deductibles and out-of-pocket costs.

Modest income in early retirement can qualify for ACA subsidies that substantially reduce this cost. But drawing income (including Roth conversions) to stay below subsidy cliffs adds a layer of planning complexity.

A comprehensive early retirement analysis models the healthcare bridge cost explicitly, including sensitivity analysis on ACA subsidy eligibility.
