          How this works

          Every dollar fills the steps in order. When a step is full, the rest spills to the next one.

          1. Starter emergency fund: $1,000 or one month of essentials, whichever is smaller.
          2. Employer match: raise your 401(k) to the percent your employer matches. It’s free money.
          3. High-interest debt (8% or more): highest rate first. Your minimums keep going on everything.
          4. Full emergency fund: 3 months of essentials (slide to 6).
          5. HSA if your health plan qualifies: up to $4,400 just you, $8,750 family (+$1,000 at 55+).
          6. Roth IRA: up to $7,500 ($8,600 at 50+). The limit shrinks for single incomes from $153,000 to $168,000 ($242,000 to $252,000 married, jointly). We use your yearly income as a stand-in for the IRS’s income measure.
          7. 401(k) toward the max: up to $24,500 of your own money ($32,500 at 50+).
          8. Debt at 4–8%: pay it off, invest, or split it. Your call.
          9. Brokerage and other goals: whatever is left.

          Debt under 4% gets its regular payment only. Payoff dates use monthly interest (rate ÷ 12) and assume you keep paying your minimums. When a debt is gone, its old minimum joins your goal money. Empty take-home is estimated at 75% of income ÷ 12, and empty essentials at half of take-home. 401(k) amounts are what goes into the account. Taxes, raises and investment growth are left out.

          The fine print

          Educational only, not financial advice. This is a simple guide to help you decide what to fund first. Your situation may call for a different order.

          Limits are the IRS’s 2026 limits: 401(k) $24,500 (plus $8,000 at 50+), IRA $7,500 (plus $1,100 at 50+), Roth IRA income phase-out $153,000–$168,000 single and $242,000–$252,000 married filing jointly, HSA $4,400 self-only and $8,750 family.
