You can optimize your savings rate for years, invest consistently, and pay down debt — and still have no clear answer to the question that actually matters: how close am I to financial independence?
Your savings rate tells you how fast you’re moving. Your net worth tells you how far you’ve come. Without both numbers, you’re navigating without a map. Knowing how to track your net worth — and more specifically, how to track the right portion of it — is what turns a collection of account balances into a measurable progress percentage toward your FIRE number.
This guide covers the full picture: what to include in your net worth calculation, why total net worth and investable net worth are different things (and which one actually matters for FIRE), a worked example with real numbers, and a simple system for tracking it over time without turning it into a second job.
What Net Worth Actually Is (And Why Income Doesn’t Tell You)
Net worth is assets minus liabilities. Everything you own, minus everything you owe. It’s not a measure of income, earning power, or lifestyle — it’s a measure of what you’ve accumulated.
That distinction matters more than it sounds. Someone earning $200,000 a year with no savings and $300,000 in student and consumer debt has a lower net worth than someone earning $60,000 who has spent 10 years investing 40% of their income. Income is the rate at which money flows in. Net worth is what remains after you decide what to do with it.
According to the Federal Reserve’s 2022 Survey of Consumer Finances — the most comprehensive household wealth dataset available in the US — the median net worth of American households is $192,700.
For FIRE pursuers, the target isn’t a national average — it’s your own FIRE number, calculated as your expected annual spending in retirement multiplied by 25.
Total Net Worth vs. Investable Net Worth: The Distinction That Changes Everything
Total net worth includes everything: investment accounts, retirement accounts, home equity, car equity, personal property. It’s a complete snapshot of your financial position. But not all of that wealth can generate the passive income you need to retire early. Your car doesn’t produce returns. Your primary home doesn’t pay you a dividend unless you sell it or rent it out.
Investable net worth strips out the illiquid, non-income-producing assets and focuses on what actually compounds toward your FIRE number. For most FIRE pursuers, this means:
- Retirement accounts (401(k), Traditional IRA, Roth IRA)
- Taxable brokerage accounts
- Cash and high-yield savings (beyond your emergency fund)
- HSA balances invested for growth
What investable net worth typically excludes:
- Primary home equity (unless you plan to downsize and deploy that capital)
- Vehicle equity
- Personal property (jewelry, collectibles, furniture)
- Emergency fund (this is a separate reserve — see our guide on how to build an emergency fund)
While researching this topic, one thing stood out consistently: even financially engaged people — those already tracking their savings rate, reading FIRE content, and investing regularly — often conflate total net worth with investable net worth when estimating their FIRE timeline. The result is systematically overestimating readiness. A $600,000 total net worth with $200,000 in home equity and $50,000 in car and personal property leaves only $350,000 in investable assets — barely over a third of the way to a $1 million FIRE target, not over half.
This is why tracking investable net worth separately is not a pedantic distinction. It’s the difference between accurate and inaccurate progress tracking.
How to Calculate Your Net Worth: Step by Step
The formula is simple. The discipline is in gathering accurate numbers.
Step 1: List all your assets
Go through every account and asset class. Be honest about current market value, not purchase price or hoped-for future value.
Financial assets (investable):
- Checking and savings account balances
- Emergency fund (note: track separately from investable assets)
- Taxable brokerage accounts (current market value)
- 401(k) and employer retirement plans
- Traditional IRA and Roth IRA
- HSA (if invested, not just held as cash)
- Crypto holdings (if applicable)
Non-financial assets (total net worth only):
- Primary home (current market value — check Zillow or Redfin for a reasonable estimate)
- Investment property equity, if any
- Vehicle current value (Kelley Blue Book)
- Other valuable property
Step 2: List all your liabilities
- Mortgage balance outstanding
- Student loan balance
- Car loan balance
- Credit card balances
- Personal loans
- Any other debt
Step 3: Calculate
Total net worth = all assets − all liabilities
Investable net worth = financial/investable assets − all liabilities (or just the liabilities tied to non-investable assets, depending on your approach — more on this below)
A practical note on liabilities: some people subtract all liabilities from investable assets; others only subtract debts directly tied to investable accounts (margin debt, for example) and leave the mortgage and car loan attached to the assets they relate to. For FIRE tracking purposes, the simplest and most conservative approach is to calculate total net worth normally, then identify the investable portion of assets separately and track it as its own number.
The FIRE Progress Formula
Once you have your investable net worth, you can calculate a number that no generic net worth guide will give you: your percentage progress toward financial independence.
The formula is straightforward:
FIRE progress (%) = investable net worth ÷ FIRE number × 100
Your FIRE number is your expected annual spending in retirement multiplied by 25 — the inverse of the 4% safe withdrawal rate established by the Trinity Study. If you’re not sure of your exact FIRE number, the FIRE Calculator will generate it from your inputs in minutes.
This single percentage — investable net worth divided by your FIRE number — is the clearest progress metric available. It tells you not just how much you have, but how close you actually are to the finish line.
Worked Example: Marcus’s Net Worth Snapshot
Marcus is 34, earns $95,000 a year, rents his apartment, and has been investing seriously for four years. His expected annual spending in retirement is $50,000, giving him a FIRE number of $1,250,000.
Marcus’s assets:
| Asset | Value | Investable? |
|---|---|---|
| Checking account | $4,200 | Yes |
| High-yield savings (emergency fund) | $18,000 | No (reserved) |
| Additional HYSA (above emergency fund) | $6,500 | Yes |
| 401(k) | $87,000 | Yes |
| Roth IRA | $31,000 | Yes |
| Taxable brokerage | $44,000 | Yes |
| Car (current value) | $11,500 | No |
Marcus’s liabilities:
| Liability | Balance |
|---|---|
| Car loan | $7,200 |
| Student loans | $22,000 |
| Credit cards | $0 |
Total net worth: ($4,200 + $18,000 + $6,500 + $87,000 + $31,000 + $44,000 + $11,500) − ($7,200 + $22,000) = $202,200 − $29,200 = $173,000
Investable net worth: ($4,200 + $6,500 + $87,000 + $31,000 + $44,000) − ($22,000 student loans) = $172,700 − $22,000 = $150,700
Note: Marcus includes his student loan debt against his investable net worth because it’s not tied to a specific asset — it’s general debt that reduces his investable position. His car loan is netted against his car’s value in total net worth.
FIRE progress: $150,700 ÷ $1,250,000 = 12.1%
Marcus has cleared 12% of his FIRE number in four years of serious investing. At his current savings rate of roughly 35%, compounding will accelerate this number substantially in the next decade — but that 12.1% is the honest starting point. Not a rough “I have about $173k,” but a precise measure of where he stands relative to where he needs to be.
What to Do About Home Equity
The home equity question comes up every time this topic is discussed, and most answers hedge it into uselessness. Here is a direct answer.
If you own a home and plan to live in it indefinitely without accessing its equity, do not count home equity toward your FIRE number or your investable net worth. Track it separately as part of your total net worth, but keep it out of your FIRE progress calculation. A house you live in does not pay dividends, and it does not support a 4% withdrawal.
If you plan to downsize before or during retirement and deploy the equity into investments — a legitimate and common FIRE strategy — then you can include the projected net proceeds after selling costs as a future investable asset. Do not include the full market value; closing costs, agent fees, and capital gains taxes will reduce what you actually pocket.
Investment properties are a different matter. Rental income-producing real estate can legitimately contribute to financial independence. Whether to include equity from investment properties depends on whether you plan to sell them and reinvest, or hold them as income-generating assets. Either way, track them separately from your primary residence and label them clearly in your records.
How to Track Your Net Worth Over Time: A Simple System
The single calculation is useful. A running record is what generates insight.
How often to update
Monthly is the standard recommendation, and it’s the right one — frequent enough to catch meaningful changes, not so frequent that market noise drives unnecessary anxiety. Set a recurring calendar reminder for the same date each month (the first of the month works well) and spend 15 to 20 minutes updating your numbers.
Quarterly is acceptable if monthly feels burdensome. Annual is not enough — too much can change in a year without you noticing.
What to record each time
At minimum, log three numbers each month:
- Total net worth
- Investable net worth
- FIRE progress percentage
Over time, the trend in these three numbers tells you more than any single snapshot. A month where your investable net worth drops 4% because markets fell is not a crisis — it’s a normal fluctuation. A year where your FIRE progress percentage barely moved despite consistent contributions might indicate lifestyle creep eating your savings rate, or a need to revisit your asset allocation. The savings rate drives the contributions; the net worth trend shows the cumulative result.
Tools: spreadsheet vs. app
Two approaches work well, and the best one is whichever you’ll actually use consistently.
Spreadsheet: Full control, no subscription, no third-party access to account data. A simple Google Sheet with a monthly row per account and a summary tab for total net worth, investable net worth, and FIRE progress percentage is sufficient. The main downside is manual data entry — which takes longer but forces you to actually look at every account.
App: Empower Personal Dashboard (formerly Personal Capital) is the strongest free option for net worth tracking. It connects to bank accounts, brokerage accounts, retirement accounts, and even mortgage balances, updating your net worth automatically. Its dashboard shows a net worth trend chart over time and breaks down assets by category. It’s particularly well suited to FIRE tracking because it aggregates investment accounts in one view and shows portfolio allocation alongside the net worth figure. The net worth tracking feature is free — Empower’s paid advisory service is separate and not required. We also cover Empower and its main alternatives in detail in the Best Budgeting Apps comparison.
One practical note: even if you use an app for automated tracking, calculate your investable net worth and FIRE progress percentage manually at least quarterly. Most apps do not make the total vs. investable distinction for you — they show total net worth. The FIRE progress percentage requires you to make that calculation yourself.
How to Interpret Month-to-Month Changes
Net worth will fluctuate. Markets move. Property values shift. Some months your number goes down despite doing everything right.
Three principles help here:
Track the trend, not the snapshot. A single month’s number is almost meaningless. A 12-month or 24-month trend is where the signal lives. If your investable net worth is growing over a rolling 12-month period while your savings rate remains consistent, you’re on track — regardless of what happened in any individual month.
Separate contribution growth from market growth. When your net worth rises $8,000 in a month, it matters whether $6,000 of that came from your own contributions and $2,000 from market returns, or vice versa. Early in your FIRE journey, contributions dominate. Later, as your investable net worth grows, market returns will increasingly outpace your monthly contributions — which is exactly how compounding is supposed to work. Tracking these separately helps you understand which engine is doing the work.
Don’t let a down month stop the habit. The months when your net worth drops are the most important months to log accurately. Tracking through volatility builds the long-term record that shows your actual progress — including that you kept investing through the difficult periods.
Recommended Reading
Two books that directly inform how to think about net worth growth and the wealth-building behaviors behind it:
The Simple Path to Wealth by JL Collins — the clearest available explanation of how consistent index fund investing builds investable net worth over time, and why the simplest approach tends to outperform more complex strategies.
The Millionaire Next Door by Thomas J. Stanley and William D. Danko — a data-driven examination of how wealth actually accumulates, and why net worth and income are far less correlated than most people assume. The contrast between high-income earners with low net worth and modest-income earners with high net worth is one of the more useful reframes in personal finance.

Key Takeaways
- Net worth is assets minus liabilities. It measures what you’ve accumulated, not what you earn.
- Total net worth and investable net worth are different. For FIRE tracking, investable net worth is the number that matters — it excludes home equity, vehicles, and personal property that don’t compound toward your FIRE number.
- Your FIRE progress percentage = investable net worth ÷ FIRE number × 100. This is the most useful single metric for measuring progress toward financial independence.
- Home equity should not count toward your FIRE number or investable net worth unless you plan to access it by selling and reinvesting.
- Track your numbers monthly. Log total net worth, investable net worth, and FIRE progress percentage. The trend over 12 to 24 months tells you more than any single month’s snapshot.
- Use Empower for automated tracking, or a simple spreadsheet if you prefer manual control. Calculate the investable net worth and FIRE progress percentage yourself regardless of which tool you use.
Your Next Step
If you haven’t calculated your FIRE number yet, start there — use the FIRE Calculator to get your target based on your expected spending. Then come back and run your investable net worth calculation to find your current progress percentage. That number — however small it is today — is your actual starting point.
Once you have both numbers, set up your tracking system. Pick a date, log your first snapshot, and add a recurring monthly reminder. The habit matters more than the method.

Frequently Asked Questions
Should I include my home in my net worth?
Yes, include it in your total net worth — your home is an asset with real value. But do not count home equity toward your investable net worth or your FIRE progress calculation unless you plan to sell and redeploy the equity into investments. A home you live in does not generate returns that support a 4% withdrawal rate.
What’s the difference between net worth and investable net worth?
Total net worth includes all assets — home equity, vehicles, personal property — minus all liabilities. Investable net worth includes only the assets that compound and generate returns: investment accounts, retirement accounts, and liquid savings beyond your emergency fund. For FIRE planning, investable net worth is the number that determines how close you are to financial independence.
How often should I track my net worth?
Monthly is ideal. It’s frequent enough to catch meaningful changes and build an accurate long-term trend, but not so frequent that daily market movements distort your perspective. Set a recurring reminder for the same date each month and treat it as a 15-minute financial check-in.
What’s a good net worth by age?
For FIRE pursuers, the more useful benchmark is your FIRE progress percentage rather than a national average by age. That said, the Federal Reserve’s 2022 Survey of Consumer Finances reported median net worth of $39,000 for households under 35, $135,600 for 35–44, and $247,200 for 45–54. These are general population figures — FIRE pursuers with high savings rates typically build net worth significantly faster than the median.
My net worth dropped this month. What should I do?
Log it accurately and keep going. A single month’s drop — particularly if driven by market movements — is normal and expected. What matters is whether you continued contributing and whether the 12-month trend is still positive. If your net worth is consistently flat or declining despite regular contributions, that’s a signal to review your savings rate, spending, or asset allocation. A one-month dip is not.
