To achieve Coast FIRE, prioritize front-loading your retirement accounts to reach a "critical mass" of $500,000 by your 30s, which can grow to $5 million by age 65 through compounding. Focus your portfolio on S&P 500 or broad market index funds, using a conservative 7% real return projection to ensure a margin of safety against inflation. Maximize tax-free growth by utilizing a Roth IRA as early as possible; parents should consider opening Custodial Roth IRAs for children with earned income to leverage a 40-year investment horizon. Accelerate your savings rate by aggressively minimizing the "Big Three" expenses—Housing, Transportation, and Food—to free up capital for early-life contributions. Once your "Coast" number is hit, you can safely transition to lower-stress work or increase lifestyle spending, as your future retirement is already mathematically secured.
