Direct answer: Retirement readiness requires adequate accumulation (savings reaching 10 to 12 times final salary by target retirement date), sustainable withdrawal rate (4% or less of portfolio annually), appropriate asset allocation for the time horizon and drawdown tolerance, and a clear income replacement plan that integrates Social Security, pension income, and portfolio withdrawals. Most shortfalls trace to starting too late, saving too little, or withdrawing too much in early retirement.
Am I on Track for Retirement? A Diagnostic Checklist
Key Takeaways
- The 4% rule (withdraw 4% of portfolio in year 1, adjust for inflation annually) has historically sustained a 30-year retirement with 90%+ probability using a 60/40 portfolio; a 3% withdrawal rate extends that to 40+ years.
- Social Security benefits are reduced by 30% for claiming at 62 versus 70; delaying Social Security is equivalent to buying inflation-protected annuity income at a rate that is difficult to match in the private market.
- Sequence-of-returns risk (bad returns in the first 5 to 10 years of retirement) is more damaging to portfolio longevity than the same average return experienced in a different order; maintaining a 1 to 2 year cash buffer reduces sequence-of-returns exposure.
- Required minimum distributions (RMDs) from traditional IRAs and 401(k)s begin at age 73 (SECURE 2.0) and increase as a percentage of the account each year, potentially increasing taxable income significantly at ages 75 to 85.
- Healthcare costs are the most underestimated retirement expense; Fidelity estimates a 65-year-old couple needs approximately $315,000 (2023 dollars) for healthcare costs in retirement excluding long-term care.
Accumulation Check: Are You on the Right Trajectory?
The Fidelity savings milestones provide the most widely used accumulation benchmarks: 1x salary by 30, 3x by 40, 6x by 50, 8x by 60, 10x by 67. These assume a 15% savings rate and a 90% income replacement rate, both conservative. For investors above these milestones, the trajectory is positive. For investors below, calculate the required monthly savings rate to reach the target using a retirement calculator, and compare to the current savings rate. A gap between required and actual savings rate is the actionable finding. Note: these benchmarks assume starting saving at age 25; starting later requires proportionally higher savings rates.
Withdrawal Rate Check: Is Your Target Withdrawal Sustainable?
Calculate the target withdrawal rate: divide planned first-year withdrawals by total portfolio value. Withdrawals above 4% on a retirement expected to last 30+ years carry historically elevated depletion risk. Withdrawals above 5% are historically unsustainable across most historical start dates for 30-year retirements. If the target withdrawal rate is above 4%, the options are: delay retirement (more accumulation, fewer withdrawal years), reduce planned spending, increase Social Security income by delaying claiming, or accept a higher depletion probability. The withdrawal rate is the single most important number in retirement income planning.
Social Security Optimization Check
Social Security benefits increase by approximately 8% per year for each year of delay between age 62 and 70. A married couple maximizing Social Security should typically: have the higher-earning spouse delay to 70 (maximizing the survivor benefit), and have the lower earner claim earlier to provide income during the delay period. The break-even age for delaying Social Security (the age at which cumulative delayed benefits exceed cumulative early benefits) is typically 78 to 82; any individual who expects to live past 80 benefits financially from delaying.

Healthcare and Long-Term Care Gap Check
Healthcare is the most common retirement planning gap. Check: Medicare eligibility begins at 65 (not Social Security full retirement age); if retiring before 65, the cost of private health insurance to bridge the gap must be explicitly budgeted. Medicare does not cover long-term care; private long-term care insurance or self-insurance (setting aside $300,000 to $500,000) is required to avoid spending down assets on care costs. The average long-term care need is approximately 3 years; the cost for nursing home memory care can exceed $120,000 per year in many U.S. markets as of 2024.
Frequently Asked Questions
What does 'income replacement rate' mean and what should it be?
Income replacement rate is the percentage of pre-retirement income that retirement income will need to replace. The standard assumption is 70% to 80% of pre-retirement income, reflecting the typical reduction in expenses (no more saving for retirement, no payroll taxes, potentially lower housing costs, lower transportation). Higher-income individuals often need lower replacement rates as a percentage; lower-income individuals often need higher replacement rates because a larger share of expenses are fixed necessities.
How does the 4% rule apply if I have pension or Social Security income?
The 4% rule applies to the portfolio withdrawal component only. Social Security and pension income cover a base layer of expenses; the portfolio covers the remainder. If Social Security replaces 40% of pre-retirement spending and the target replacement rate is 80%, the portfolio only needs to cover 40% of pre-retirement spending. This dramatically reduces the required portfolio size and the withdrawal rate risk.
Should I convert traditional IRA assets to Roth before retirement?
Roth conversions make mathematical sense when the current marginal tax rate on the conversion amount is lower than the expected marginal rate on future distributions. Common scenarios where conversion is favorable: years with unusually low income (temporary retirement, sabbatical, job change), before RMDs begin pushing income higher at age 73, and when the portfolio has grown substantially and future RMDs will be large. A tax advisor with retirement income planning experience can model the break-even across the specific numbers.
