Key Insight

$125k puts you in strong FIRE territory. At 45% savings (~$56k/year), you reach $1.4M in 18 years. The trap at this income level is lifestyle creep — restaurant dinners, newer car, bigger apartment — that consumes the extra income without moving FIRE closer. Protect your savings rate as income grows.

💡 Pro tip: At $125k, consider a tax optimization strategy: max HSA ($4,150 single / $8,300 family) + 401(k) ($23,000) + Roth IRA ($7,000) = $34,150 in tax-advantaged accounts. This alone represents a 27% savings rate with significant tax benefits.
