In 2015, I was earning more than ever and felt confident about my financial future. Then I actually ran the numbers. Despite years of steady income, my retirement projection revealed a massive shortfall; I wasn’t saving nearly as much as I thought. That’s the problem most people never confront.
Nearly 40% of workers aged 55-65 have no retirement plan at all, yet 45% feel financially prepared. Americans scored below 50 out of 100 on a national retirement readiness index, a “moderate risk” zone where feeling ready and being ready are entirely different things.
This experiment walks you through five metrics that actually matter, and the specific steps to close any gaps you find.
Why Most People Avoid the Assessment
Most people avoid checking their retirement readiness for the same reason they avoid checking their bank balance after vacation: fear of bad news. That’s exactly what I experienced when I first ran my own projection, and the gap it revealed was one of the early nudges toward everything that followed.
Retirement readiness isn’t about hitting a precise number. It’s about ensuring your systems work when you’re not actively managing them. Understanding different FIRE variations, such as Coast FIRE or Lean FIRE, helps clarify your target, but first, you need an honest baseline.
The Tools That Changed Everything
In those early years, I typed balances from different accounts into a spreadsheet and projected decades ahead with a simple calculator. Moving to one dashboard that combined expenses and net worth turned retirement planning from guesswork into what I call a “quantitative map for a qualitative goal of freedom.” The tool matters less than the habit, and setting one up is covered in building a financial tracking system. For projections, free tools like the Vanguard Retirement Calculator and Fidelity’s Retirement Score are enough to start.
The 5 Critical Metrics You Must Track
Checking your 401(k) quarterly and hoping it goes up is like navigating by only watching your speedometer. A comprehensive assessment requires five metrics.
Savings Rate. It predicts your time to FIRE better than almost anything. I’ve tracked this throughout my entire journey because it cuts through income fluctuations to show actual progress. Calculate it: Amount Saved ÷ (Amount Saved + Amount Spent) × 100. Target 15-20% for traditional retirement, or 30-50%+ for early independence. Even implementing the pay yourself first strategy with a 1-2% increase compounds dramatically.
Year-Over-Year Net Worth Growth. It reveals your momentum by tracking net worth and cash flow over time. Calculate: (Current Net Worth – Previous Year Net Worth) ÷ Previous Year Net Worth × 100. Target 10-20% annually. In my first five years (2007-2012), growth was erratic, at times negative, due to student loan repayments. Once I hit my stride, I averaged 15-18% annual net worth growth through a combination of a savings rate in the mid-to-high 20s, market returns, and later real estate. This metric shows momentum, not just market performance. Average retirement balances run around $1.5M for Baby Boomers and just under $1M for Gen X, but your target should align with your FIRE number, not arbitrary averages.
Projected Withdrawal Rate. It determines sustainability. Calculate: (Annual Expenses ÷ Portfolio Value) × 100. Your target is 4%, the safe withdrawal rate behind the 4% rule. With $1.25 million saved and $100,000 in annual needs, you’re at 8%, a red flag that requires either $2.5 million saved or reducing expenses. At 8%, one bad year early on can push withdrawals past 10%, which is how portfolios fail under sequence-of-returns risk.
FIRE Multiple. It measures how many times your annual expenses you’ve saved, targeting 25x. Spending $100,000 annually means your FIRE number is $2.5 million. I track milestones at 10x, 15x, and 20x. It shows how expense reductions accelerate your timeline. Cutting $5,000 annually reduces your FIRE number by $125,000.
Inflation-Adjusted Purchasing Power. With 78% worried about the impact of inflation, you must use real returns. If your portfolio averages 10% but inflation runs 3%, your real return is 7%. Understanding the impact of inflation ensures projections remain grounded in reality.
How to Conduct Your First Assessment
The hardest part is starting; I remember the anxiety before running that first projection. Part of me didn’t want to know. But you can’t fix what you don’t measure.
List every account: 401(k), IRA, Roth IRA, taxable brokerage, savings, real estate equity, and HSA. My portfolio includes 401(k) optimization, low-cost index funds, backdoor Roth IRAs, mega backdoor Roth IRAs, and HSA strategies. Tools like Monarch or Empower automatically aggregate everything.
Calculate real expenses; this trips up almost everyone. When I finally tracked every dollar for three months in 2015, I was shocked. What we thought we spent and what we actually spent were far apart. The difference wasn’t one big thing. It was $80 here for dinners out, $120 there for subscriptions we’d forgotten, $200 for “miscellaneous” that accumulated invisibly.
That first honest expense audit is the foundation everything else is built on. Lifestyle inflation can quietly erode progress. Track current annual spending, then project retirement needs. Many assume 70-80% of current expenses, but this oversimplifies things. Creating a budget reveals actual baseline costs.
Run projections using Empower’s Retirement Planner or Fidelity’s Retirement Score with a 7% return after inflation (10% before). Plug in your actual numbers: current balances, monthly contributions, expected Social Security benefit, and target retirement age. Then test at least three scenarios (target age, five years earlier, five years later) to see how each variable moves the needle.
Compare your current investments (not your home equity) to your FIRE number to calculate your funded ratio: (Current Savings ÷ FIRE Number) × 100. If your FIRE number is $2.5 million and you’ve saved $1 million, your funded ratio is 40%. That single number tells you more about your readiness than any balance ever will. After my 2015 wake-up, I increased my 401(k) contributions to the maximum, switched to lower-cost investments, set up automated savings in my taxable brokerage accounts, and committed to monthly budget reviews.
The Lifestyle Factors Most People Ignore
Healthcare planning scored lowest of any category on that readiness index. In one survey of near-retirees and retirees, about four in five ranked healthcare costs among their top three financial worries. I’m maximizing HSA contributions and factoring in pre-Medicare healthcare costs.
Social Security belongs in every assessment. Create your account at ssa.gov and check your estimated benefit; it’s based on your actual earnings history, not guesses. If it covers $25,000 of your $100,000 annual need, your portfolio only needs to fund $75,000. When and how to claim Social Security has its own experiment.
Geographic location dramatically affects readiness, because lower spending lowers your FIRE number directly. Geographic arbitrage can accelerate retirement by 5 to 10 years.
Purpose beyond work is the non-financial crisis most ignore. My assessment now includes what I’ll do with my time and what gives me purpose. Financial independence without early retirement means achieving security while continuing meaningful work by choice, not necessity.
Time horizon matters enormously. U.S. life expectancy is about 79 years, but that’s an average from birth, and a healthy 65-year-old couple has a nearly 50% chance that one partner lives to 90. Planning to 95-100 provides the safety margin you actually need, while also accounting for sequence of return risk in early retirement years.
Common Assessment Mistakes
Assuming future income solves current gaps was my biggest mistake. As my income grew, I assumed readiness would follow. Instead, spending crept up with each raise; each bump felt like permission to upgrade part of our lifestyle rather than an opportunity to save all of it. Someone I mentored shared that raises from $65K to $90K went entirely toward lifestyle upgrades, resulting in years of income growth with no progress toward retirement.
The pattern breaker? I started automating savings increases on the same day raises took effect. From then on, at least half of every raise went straight to retirement accounts. Combined with our second income, my savings rate climbed from about 15% to nearly 28%.
Overlooking taxes creates false confidence. A $1 million traditional 401(k) isn’t actually $1 million of spending money; every withdrawal is taxed as income, so add those taxes to your expenses when you calculate your FIRE number. My strategy includes tax diversification: traditional 401(k), backdoor Roth, mega backdoor Roth, taxable brokerage for pre-59½ flexibility, and HSA.
Using overly optimistic returns builds plans on hope. I plan on 7% a year after inflation (10% before), in line with historical S&P 500 performance after inflation. Americans hold 69% in stocks, 22% in bonds, and 9% in cash, a mix that won’t consistently deliver that.
Failing to reassess regularly happens through inaction. I do a full review once a year and check net worth quarterly, plus mini-assessments after major life events. Each reassessment lets you course-correct slipped savings rates or expense creep.
Next Steps Based on Your Results
If you’re behind: Starting far behind extends the timeline; it doesn’t determine the outcome. Use all three levers: increase your savings rate by 1-2% annually, extend your work timeline by 2-5 years, and reduce expenses through intentional spending or geographic relocation. Coast FIRE works well as an intermediate milestone.
One person I mentored discovered at 50 they were significantly behind. They increased contributions from 6% to 15% using catch-up contributions, adjusted their timeline from 65 to 67, and downsized their living arrangements. Within 18 months, their funded ratio went from 62% to 98%. It was consistent, sustainable adjustments compounding over time.
If you’re on track: Focus shifts to optimization. Maintain progress through complete financial automation. Seek efficiency gains through tax optimization and review your asset allocation. Understanding the stages of financial freedom helps you identify where you are and what comes next.
If you’re ahead: Consider which FIRE variations align with your values. Many people discover that financial independence doesn’t mean stopping work entirely. Test part-time work or passion projects while still employed to see what truly fulfills you.
Regardless of where you fall: document your systems so they run on autopilot, set a calendar reminder for your yearly review, continue financial education, and balance optimization with actually enjoying life. Financial independence means nothing if you sacrifice everything meaningful to achieve it.
Your Assessment Is a Living Process
My tracking has evolved from crude manual methods to a single dashboard covering every account. Readiness is dynamic, not static; assessment is more about awareness than precision.
What matters are consistent systems, automated habits, and regular reviews. Choose one tracking tool today, even a spreadsheet, because the tool matters less than the habit. You don’t need to jump from 5% to 50% overnight. You need 5% to 6% this year, 7% next year, and 8% after that. Minor sustained improvements beat dramatic, unsustainable changes. One thing your assessment can’t control is the market, and market cycles can move your FIRE date in either direction.
What You Need to Remember
- Track five metrics (savings rate, net worth growth, withdrawal rate, FIRE multiple, and inflation-adjusted purchasing power) to measure actual retirement readiness instead of guessing.
- Calculate your funded ratio (Current Savings ÷ FIRE Number × 100) to get the single number that reveals your true readiness better than any account balance.
- Do a full assessment yearly, check net worth quarterly, and run mini-reviews after major life events to catch gaps before they compound.
- Increase your savings rate by 1-2% per year rather than attempting dramatic, unsustainable jumps that lead to burnout.
- Run your first projection even if the numbers scare you, because the gap between what you assume and what’s real is usually the most important discovery.
Questions I Always Get
How accurate do my expense projections need to be for a meaningful assessment? Directionally accurate beats falsely precise. Start with three months of actual spending tracking rather than estimates; most people underestimate by 20-30%, which is exactly the gap that derails projections. For retirement estimates, add a 10-15% buffer for healthcare costs and unexpected expenses. Reassess annually since spending patterns shift over time, especially around life transitions like kids leaving home or mortgage payoff.
Should I include my home equity in retirement readiness calculations? Count it in your net worth, but not toward your FIRE number. Your FIRE number measures what your investments can fund at 4%, and you cannot eat your house. If downsizing or geographic arbitrage is part of your plan, count only the cash you’d actually invest after realistic selling costs.
What if my assessment shows I’m decades behind where I should be? A significant gap is data, not a verdict. Break the shortfall into smaller targets by calculating what it would take to close 10% of the gap annually. Focus on your savings rate trajectory rather than the absolute number. Many people discover that combining modest savings increases, extended timelines, and expense adjustments closes seemingly impossible gaps within 5-7 years.
How do I factor in an expected inheritance or windfall? Never include uncertain money in your baseline assessment. Run two scenarios: one without the inheritance and one with a conservative estimate of 50-70% of the expected value. If the windfall materializes, treat it as acceleration toward your FIRE number rather than lifestyle expansion.
Do I need a financial advisor to do a proper retirement assessment? You don’t need one to start. The five metrics in this experiment work with free tools like Fidelity’s Retirement Score or a simple spreadsheet. A fee-only advisor adds value for complex situations like coordinating multiple income sources, optimizing Social Security timing, or managing tax-efficient withdrawals across account types. Do the self-assessment first so you arrive with informed questions instead of starting from zero.
