How He’ll Hit $500K by 30 (Coast FI Plan)

What It Covers

Mechanical engineer Evan Lawler, age 25, outlines his Coast FI strategy targeting $500,000 in retirement accounts by age 30, which projects to $5.2–5.3 million by age 65 using a 7% growth rate, enabling roughly $200,000 annual retirement income via the 4% rule.

Key Questions Answered

• •Coast FI math: Targeting $500,000 by 30 is more psychologically achievable than building a $5,000,000 portfolio over 20 years, yet produces the same retirement outcome. Evan invests $3,300 per month at a 7% projected growth rate, currently tracking toward $564,000 at age 32 without income increases factored in.
• •Housing as the primary lever: Evan spends under $40,000 annually on a sub-$100,000 salary by splitting $1,195 monthly rent in a 650-square-foot Philadelphia apartment. Housing cost is the single variable that most directly controls savings rate, and Philadelphia offers a rare combination of solid engineering salaries alongside genuinely affordable rental options.
• •Roth-first allocation strategy: Evan directs 100% of discretionary contributions into Roth IRA and Roth 401(k), holding FXAIX exclusively. The rationale is that early career years are the optimal "first in" window for Roth contributions, locking in tax-free growth before income and tax brackets rise, while retaining flexibility against future tax rate changes.
• •Raise negotiation timing: Salary increases are most effectively secured by approaching a manager six or more months before review cycles, asking explicitly what milestones unlock promotion eligibility. Budget decisions for raises are often finalized months in advance, so early conversations dramatically increase the probability of an approved off-cycle or annual increase.
• •Praise folder for salary leverage: Maintaining a dedicated folder of positive feedback emails from colleagues and managers builds a concrete, printable case for raise requests. Presenting documented evidence of contributions shifts the conversation from a subjective ask to a data-supported negotiation, a tactic credited to personal finance author Erin Lowry of Broke Millennial.
