Coast FIRE at 60 on a $150K salary is is highly achievable — maxing a 401k alone covers most of the required monthly savings. Your FIRE target is $2.4M ($97K/year at 65% income replacement). To coast there from age 60, you need $1.7M invested by then — that's your Coast FIRE number. At 7% real returns over 5 years, $1.7M compounds to approximately $2.4M by age 65.
Starting at age 47 with $38K, saving $6K/month for 13 years reaches $1.7M — a 52% savings rate on your $150K gross income. This is an aggressive savings rate that requires significant lifestyle discipline but delivers the maximum compounding benefit. After 60, you no longer need to save for retirement — you only need to earn enough to cover your $8K/month in living expenses.
The 60-year coast window for $150K earners works particularly well because at 60, 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 $150K + age 60 scenario works best with tax-advantaged account prioritization. Max your employer 401k match ($1000/month in free matching at 4%), then Roth IRA ($583/month = $7,000/year), then additional 401k contributions up to $6K/month total. Keeping investment costs low (under 0.1% expense ratio) on a $1.7M portfolio saves approximately $16K per year in avoided fees — compounding into significant additional wealth over 5 years.
