Coast FIRE at 50 on a $50K salary is requires maximum frugality and lean spending to reach the coast threshold. Your FIRE target is $813K ($32K/year at 65% income replacement). To coast there from age 50, you need $294K invested by then — that's your Coast FIRE number. At 7% real returns over 15 years, $294K compounds to approximately $812K by age 65.

Starting at age 37 with $13K, saving $1K/month for 13 years reaches $294K — a 25% savings rate on your $50K gross income. This is a meaningful but achievable savings rate for a focused saver at this income level. After 50, you no longer need to save for retirement — you only need to earn enough to cover your $3K/month in living expenses.

The 50-year coast window for $50K earners works particularly well because the 15-year growth window captures two complete market cycles and multiple doublings at historical return rates. Social Security at 67–70 adds $3K/month as a meaningful backstop.

One planning note: the $50K + age 50 scenario works best with tax-advantaged account prioritization. Max your employer 401k match ($300/month in free matching at 4%), then Roth IRA ($583/month = $7,000/year), then additional 401k contributions up to $1K/month total. Keeping investment costs low (under 0.1% expense ratio) on a $294K portfolio saves approximately $3K per year in avoided fees — compounding into significant additional wealth over 15 years.
