Coast FIRE at 55 on a $75K salary is is achievable with a disciplined 25–35% savings rate and modest lifestyle. Your FIRE target is $1.2M ($49K/year at 65% income replacement). To coast there from age 55, you need $620K invested by then — that's your Coast FIRE number. At 7% real returns over 10 years, $620K compounds to approximately $1.2M by age 65.

Starting at age 42 with $19K, saving $2K/month for 13 years reaches $620K — a 36% savings rate on your $75K gross income. This is an aggressive savings rate that requires significant lifestyle discipline but delivers the maximum compounding benefit. After 55, you no longer need to save for retirement — you only need to earn enough to cover your $4K/month in living expenses.

The 55-year coast window for $75K earners works particularly well because at 55, you're within striking distance of full retirement account access (at 59½), Rule of 55 benefits, and ultimately Medicare at 65 — making the coast window structurally simple. Social Security at 67–70 adds $3K/month as a meaningful backstop.

One planning note: the $75K + age 55 scenario works best with tax-advantaged account prioritization. Max your employer 401k match ($500/month in free matching at 4%), then Roth IRA ($583/month = $7,000/year), then additional 401k contributions up to $2K/month total. Keeping investment costs low (under 0.1% expense ratio) on a $620K portfolio saves approximately $6K per year in avoided fees — compounding into significant additional wealth over 10 years.
