If you've ever felt good about retirement because you crossed an age-and-salary savings benchmark, here's what crossing it actually proves. It means you've saved at an average pace for someone your age. It proves nothing about whether you can retire. That's why some people clear the benchmark and are still stuck working. A real retirement readiness checklist looks at structure, not just your account balance. Here are the seven checks that answer the question.
Get Your Debt and Cash in Order
The most controllable milestone is your debt. Either your house is paid off, or your mortgage, property taxes, and insurance together take up less than 25% of your expected retirement income. Consumer debt, meaning credit cards, car payments, and personal loans, sits at zero or on a written schedule that clears it before your last paycheck. Every dollar of debt service is a dollar you can't cut when money gets tight. You can stop eating out and postpone travel, but you can't skip the house payment. So clear consumer debt first, before you optimize anything else.
On the mortgage, it depends on the rate. Under about 5%, I'd lean toward keeping it, because your payment is fixed and inflation makes those dollars cheaper over time. Above 5%, I'd lean toward paying it off. Even a little extra each month shortens the payoff more than you'd expect, and a 30-year loan can end years earlier in retirement.
The second milestone is a cash buffer of two years of essential expenses, well past the usual six-month emergency fund. Keep it liquid in a high-yield savings account, a money market, or short-term treasuries. Six months works while you're employed, because unemployment bridges the gap to the next job. Retirement is different. Your paycheck has stopped, so if the market drops while you're selling shares for income, you pull from cash instead. Two years is about how long the market takes to recover from a bad recession. If you're 18 months out and short, stop contributing to anything that isn't liquid, except a 401(k) match and an HSA.
Bridge Healthcare Before Medicare
If you're retiring before 65, you need a written plan for health insurance until Medicare starts. That could be COBRA, the ACA marketplace, a spouse's plan, or a healthy HSA. Pick a plan and actually price it, then write that number down. This is the milestone that scares people most, usually because they've heard insurance is expensive but never priced it out.
The 2026 numbers make it real. ACA subsidies start to phase out around $84,600 in modified adjusted gross income for a married couple, and $62,600 for a single filer. Below those lines you qualify, and a 60-year-old might pay a few hundred dollars a month. Above them you're disqualified completely, and premiums run closer to $1,500 to $2,000 a month. The trap is that retirement income isn't fixed like a paycheck. Pull too much from your 401(k) in one year and you can cross the line. Which buckets you draw from is the lever, because a Roth withdrawal doesn't count toward that income figure and long-term capital gains count at a lower rate. Retiring at 65 or later, the equivalent to watch is the IRMAA cliff, which sits higher than the ACA lines and uses a two-year income lookback.
Spread Your Money Across Three Tax Buckets
Your money should sit in three buckets: pre-tax, meaning your traditional 401(k) and IRA; Roth; and a taxable brokerage account or something like real estate or notes. Most pre-retirees have 90% or more in pre-tax accounts. It looks disciplined, but it's a tax bomb waiting to go off. Every dollar you withdraw counts as ordinary income, with no flexibility. Roth money comes out tax-free after 59½, and brokerage money held over a year is taxed at long-term capital gains rates, well below ordinary income.
When pre-tax is your only source, every withdrawal can shrink your ACA subsidies, push up your Medicare premiums, and cause more of your Social Security to be taxed. So if most of your money is traditional and you're contributing without a match, move those contributions to a Roth or a taxable account. If you're a high earner who needs the deduction now, ages 60 to 63 get a super catch-up of $11,250 a year into a pre-tax account. The point is optionality, the ability to pull from multiple buckets and steer your income.
Know Your Income Gap and Stress Test the Plan
Add up your fixed monthly expenses on one side and your guaranteed income on the other, meaning Social Security, pensions, and anything you receive without selling an asset. The difference is the only number that really matters in retirement. Your portfolio balance and salary multiple are weak proxies for it. Most pre-retirees can tell you their balance to the dollar but not their monthly gap to the nearest thousand, and that's backwards.
Once you know the gap, the question is how to cover it. The most common answer is portfolio withdrawals, where the 4% rule comes in. Others are a dividend ETF that pays income without selling shares, or a bond or CD ladder timed at set intervals. Less common ones include multi-year guaranteed annuities, rental cash flow, and first-position secured notes. Any of them work as long as they close the gap. The more of it you cover without selling shares, the less the stress test matters. If guaranteed income and dividends fully cover your expenses, a 40% market drop won't touch your lifestyle.
If your plan does involve selling shares, test it against a 30% or 40% drawdown in the first three years of retirement. The 4% rule came out of historical probabilities. It described what survived across past markets, so treat it as history rather than a plan to follow. To run it yourself, pretend the market drops 40% the year after you retire and stays there three years while your bills stay the same. This is where the cash buffer earns its place. With enough cash or a big enough income floor you're fine, but without them, forced selling at the bottom turns ugly fast. One rule that helps is to sell shares only when the S&P is within 10% of its all-time high, and pull from cash otherwise. That keeps you from panic selling and missing the rebound.
Update Your Estate Documents
The easiest milestone is also the most ignored: estate documents updated within the last five years. The short list is a will or trust, a durable power of attorney, a healthcare power of attorney, and a HIPAA release. Then set beneficiary designations on every retirement account, life insurance policy, annuity, and bank account.
Here's what catches people off guard. Beneficiary designations override a will every time. If your 401(k) still lists an ex-spouse and you've since remarried and named your new spouse in the will, the ex-spouse gets the account. Most people set these once, buried in HR paperwork, and 25 years later the accounts haven't kept up. Pull every account and check who the beneficiaries are, then make sure the will is current. Most attorneys will review and update a will for around $400 to $800. This one takes the least time and prevents the most damage, so don't put it off.
What This Looks Like in Practice
A viewer named Bob is living this whole list in real time. He retired at 58. His 401(k) had to roll into an IRA within 60 days, so the rule of 55 wasn't available, and he skipped the strict 72(t) rule, so the money went into a taxable brokerage account. For healthcare he priced two options, a state-only ACA plan at $450 a month or nationwide private coverage at $990 a month, and chose the private plan for the flexibility. For income he runs a four-rung CD ladder inside an IRA with a dividend fund as backup. Social Security comes on later, and his wife has a small pension starting at 65.
Bob wasn't a high earner or unusually wealthy. He engineered these milestones before he stopped working. Hit all seven and you're ready to retire. Miss three or four and you've got a real project on your hands.
