Step 1: Calculate Your Retirement Number
Your retirement number is the portfolio size that can fund your retirement spending indefinitely. The formula has four variables: (A) estimate your annual retirement spending — most people use 70-80% of their current income as a starting point; (B) find your estimated Social Security benefit at ssa.gov/myaccount; (C) subtract B from A to find how much your portfolio must produce each year; (D) multiply C by 25 (the 4% rule). The result is your retirement number.
Worked example: Current income $70,000. Retirement spending estimate: $70,000 × 0.75 = $52,500/year. Social Security at 67: $22,000/year (from SSA.gov). Portfolio must fund: $52,500 - $22,000 = $30,500/year. Retirement number: $30,500 × 25 = $762,500. This is your target — a concrete number that makes all other planning decisions measurable.

| Your Income | Retirement Spending (75%) | SS Estimate | Portfolio-Funded Need | Your Retirement Number (×25) |
|---|---|---|---|---|
| $50,000 | $37,500 | $18,000 | $19,500/year | $487,500 |
| $65,000 | $48,750 | $21,000 | $27,750/year | $693,750 |
| $80,000 | $60,000 | $25,000 | $35,000/year | $875,000 |
| $100,000 | $75,000 | $29,000 | $46,000/year | $1,150,000 |
| $120,000 | $90,000 | $32,000 | $58,000/year | $1,450,000 |
Step 2: Check SSA.gov for Your Real Social Security Estimate
Create a free account at ssa.gov/myaccount. This provides your actual earnings record — the history of all Social Security-taxed wages you have ever earned — and your personalized benefit estimates at three ages: 62, full retirement age (67 for those born 1960+), and 70. These estimates are far more accurate than any generic calculator because they use your actual earnings history.
While you are there, review your earnings record for any errors. Missing years (common from early career jobs, name changes, or employer reporting failures) permanently reduce your benefit if not corrected. Dispute errors at your local SSA office — this 30-minute task can increase your lifetime Social Security income by tens of thousands of dollars.
Step 3: Know Where You Stand Today
Log into every retirement account you have. 401k at your current employer (log in via HR portal or the 401k provider's website — Fidelity, Vanguard, Empower, etc.). Old 401ks from previous employers (you can roll these to an IRA to consolidate). IRA accounts (at brokerages you have opened). Add all balances together for your total current retirement savings.
Many Americans have forgotten 401k accounts from previous employers. Search the National Registry of Unclaimed Retirement Benefits at unclaimedretirementbenefits.com. Also check your state's unclaimed property database. FreeERISA.com allows you to search for old 401k plans by employer. Tracking down and rolling over old accounts can add thousands to your current retirement savings without any new contributions.
Step 4: Set Up Your Account Priority Stack
Not all retirement savings vehicles are equal. The optimal contribution order maximizes every dollar of retirement savings through tax advantages and guaranteed returns. The priority order is designed to capture the highest-return opportunities first before moving to progressively lower-return options.
Optimal retirement account contribution order for first-time planners
| Priority | Account | Why | 2025 Limit |
|---|---|---|---|
| 1st | 401k up to employer match | 50-100% guaranteed return — beats everything | Variable by employer |
| 2nd | Roth IRA (if income eligible) | Tax-free growth; most investment flexibility | $7,000 ($8,000 if 50+) |
| 3rd | HSA (if HDHP eligible) | Triple tax advantage — deductible/tax-free/tax-free | $4,300 individual |
| 4th | 401k beyond employer match | Tax-advantaged; large contribution room | $23,500 total ($31,000 if 50+) |
| 5th | Taxable brokerage | No limits; taxable gains but flexible | Unlimited |
Step 5: Choose Your Investments
For first-time investors: use a target-date fund that matches your anticipated retirement year. Look for 'Target Retirement 2050' or '2055 Fund' depending on when you plan to retire. These funds are professionally managed, automatically rebalance between stocks and bonds, and gradually become more conservative as you approach retirement. Expense ratios at major brokerages are 0.10-0.15% — minimal cost for comprehensive management.
For investors who want more control: the three-fund portfolio (Total U.S. Market Index Fund + Total International Index Fund + Total Bond Index Fund) is the simplest sophisticated portfolio available. The typical allocation for someone in their 30s: 60% U.S. total market, 30% international, 10% bonds. Rebalance annually — no ongoing management required.
Step 6: Run the Retirement Calculator to Check Your Trajectory
Enter your current balance, monthly contribution (employee + employer match combined), expected return (7% for a stock-heavy portfolio), and target retirement age. The projection shows your estimated balance at retirement. Compare it to your retirement number from Step 1. If the projection exceeds your retirement number: you are on track. If it falls short: use the calculator to find what savings rate closes the gap.
Step 7: Set Up Automation and Annual Review
The final step is the most important for long-term success: automate everything so the retirement savings system runs without requiring ongoing willpower. Enable 401k auto-escalation (1% per year increase). Set up automatic IRA monthly transfer on payday. Set an annual calendar reminder to review your balance against benchmark, update your retirement number with current salary, verify beneficiary designations, and check for any investment fee changes.
- Calculate your retirement number: annual spending × 75% - Social Security estimate = annual portfolio need; multiply by 25
- Create SSA.gov account and get your actual Social Security estimate at 62, 67, and 70
- Find and total all current retirement account balances; roll over any orphaned 401ks to an IRA
- Set up automatic 401k contributions to at least the employer match; enable auto-escalation
- Open Roth IRA if eligible; set up $583/month automatic contribution into a total market index fund
- Run the retirement calculator to compare your projected balance to your retirement number
- Set an annual calendar reminder to update the projection with current balance and contribution rate

Consolidating Retirement Accounts Before Retirement
Many Americans approaching retirement have multiple orphaned 401k accounts from previous employers, multiple IRA accounts opened over the years, and a current employer plan — creating a fragmented, difficult-to-manage retirement portfolio. The case for consolidation is compelling: fewer accounts mean fewer required minimum distribution calculations at 73, easier rebalancing, lower risk of forgetting account locations, and reduced paperwork. Rolling old 401k accounts into a single Traditional IRA at a low-cost brokerage consolidates the investment universe and provides maximum flexibility for withdrawal planning and Roth conversion strategies.
The ideal consolidation target is a single IRA at a low-cost brokerage (Fidelity, Vanguard, or Schwab) that offers both Traditional and Roth IRA options, access to the full universe of low-cost index funds, and no account fees. Keep your current employer's 401k intact if you need Rule of 55 access (the ability to withdraw penalty-free from your current employer's plan after leaving at age 55). Roll all other accounts to an IRA where you have maximum investment flexibility and control. Consolidation is best completed 5-10 years before retirement when decisions can be made thoughtfully rather than during the transition.
Retirement Savings and Estate Planning Considerations
Retirement accounts are the most valuable assets many Americans own — and they have unique estate planning characteristics that non-retirement assets do not share. Retirement accounts pass directly to named beneficiaries regardless of what your will says. An outdated beneficiary designation (an ex-spouse, a deceased parent, or the default 'estate') can route your life's savings to the wrong person, through probate, or create significant tax complications for heirs. Review and update beneficiary designations on every retirement account annually — it takes 15-20 minutes and is one of the highest-impact financial maintenance tasks available.
For heirs inheriting your retirement accounts, the SECURE Act 2.0 rules require most non-spouse beneficiaries to distribute inherited Traditional IRA and 401k accounts within 10 years. In their peak earning years, this forced distribution can push heirs into high tax brackets. Roth IRA conversions during your lifetime (particularly in the low-income window between early retirement and RMD age 73) convert taxable Traditional balances to Roth — giving heirs the same 10-year distribution window but without the income tax. This Roth conversion legacy planning strategy can save heirs hundreds of thousands in income taxes.
Deep Dive: How the Fidelity Retirement Benchmarks Were Calculated
The Fidelity salary-multiple benchmarks (1x at 30, 3x at 40, 6x at 50, 8x at 60, 10x at 67) emerge from a specific set of actuarial assumptions. Fidelity modeled an employee who starts working at age 25, earns a salary that grows modestly over their career, saves consistently, and retires at 67. The 15% savings rate assumption (including employer match) invested at a 5.5% annual return (reflecting Fidelity's blended equity/bond assumption) produces these salary multiple waypoints as natural compounding checkpoints along a 42-year savings career. Understanding these embedded assumptions helps you calibrate whether the benchmarks are appropriate for your specific situation.
The benchmark assumes Social Security replaces approximately 40-45% of pre-retirement income, with the savings portfolio supplementing the rest. For workers who earn above the Social Security wage base consistently, or who plan to retire before 67, these benchmarks underestimate the required savings. For workers with defined-benefit pensions providing 25%+ income replacement, the benchmarks may overstate what the investment portfolio alone needs to provide. Use the benchmarks as orientation points — if you are significantly above or below them, investigate why before making dramatic course corrections based solely on the comparison.
