Most 401(k) advice quietly assumes a salary you don’t have. This is the other version: the playbook I ran for twenty years as a GS-8 federal employee — anesthesia technician, single paycheck, no side hustle, no inheritance. My account is the TSP, the federal government’s 401(k). Everything in it translates one-for-one: the TSP is your 401(k) or 403(b), the C Fund is the S&P 500, and the 5% match is your 5% match.
Before rates, funds, or anything else: contribute at least enough to get your employer’s full match. My match is 5% of pay. Skipping it isn’t caution — it’s a pay cut you volunteered for. The match is an instant double on those dollars, and no fund choice in any plan beats free.
I started in January 2008 at 5.44%, with a $6,236 rollover from a contractor profit-sharing plan. The balance promptly fell 37% in the crash. I kept contributing anyway. Starting small beats waiting until you can do 30% — the early dollars get the extra years, and the years are the whole game.
Out of every pay increase of at least 2%, one point goes to the future and the rest is yours to live on. Anything smaller — a flat 1%, a 1.5% cost-of-living bump — is COLA money: it all goes to living now. Run that split long enough and the rate climbs by itself: I rebuilt mine from 20% to 31% between 2023 and 2026, and it sits at 31.5% going forward. You never miss money you never saw.
My money sits in stock index funds — the C Fund is the S&P 500; your plan has an equivalent. No trading strategy, no timing. The hardest and smartest move when the market tanks is nothing, which is why my plan’s two-transfers-a-month limit is a feature, not a bug.
Seventy-two divided by your return is the years it takes to double. I run every projection at 8, 10, 12, and 14 percent so I can pick my own level of cynicism — the plan has to survive the 8% column, and anything above it is altitude. And here is the part nobody tells you: the contribution limit is the great equalizer. In 2026 the IRS lets me put in $24,500 of my own pay — the exact same $24,500 it allows someone earning $300,000. Income is what you earn. Wealth is what you don’t spend.
Twenty years of that — one rate, raised on schedule, never stopped — is how a GS-8 paycheck ends up retiring at 57 with $5 million. The statements are in the book.
