Net worth is assets minus liabilities, your financial snapshot at a point in time. For FIRE planning, net worth is the scoreboard: it tells you how close you are to the portfolio size that can fund your lifestyle.
Not every asset counts equally toward financial independence. Your FI number is based on investable assets that can generate income, not total net worth including items you would not sell or borrow against.
What counts toward your FI number
Investable assets include stocks, bonds, mutual funds, ETFs, retirement accounts (401k, IRA, Roth), taxable brokerage accounts, and cash savings. These can be withdrawn or converted to income in retirement.
Home equity is debatable. Some FIRE planners exclude primary residence equity because you need somewhere to live. Others include it if you plan to downsize or relocate. Investment properties count if they generate net rental income.
Exclude cars, furniture, and personal belongings from FI calculations. They depreciate and are not income-producing. Include them in total net worth tracking but not in your FIRE target.
Tracking progress over time
Calculate net worth quarterly or annually, not daily. The goal is trend awareness, not anxiety over market swings. A simple spreadsheet or net worth calculator is enough.
Plot investable net worth against your FI target. If your target is $1,000,000 and investable assets are $400,000, you are 40% of the way there. That percentage is more motivating than an abstract date estimate.
Track liabilities separately. Paying down a mortgage increases net worth but does not always increase investable assets. Redirecting mortgage payments to investments after payoff accelerates the FI timeline.
Common mistakes
Counting gross home value without subtracting the mortgage overstates progress. Net home equity is what matters.
Ignoring retirement account balances because they feel inaccessible. Traditional 401k and IRA balances count, you will access them in retirement with planned withdrawal strategies.
Comparing net worth to others without context. Age, location, income, and family size all affect benchmarks. Focus on your own trajectory and savings rate.
Useful milestones
Positive net worth, liabilities no longer exceed assets, is the first milestone. For many people this happens in their late 20s or 30s after student loans and early career building.
Coast FIRE and lean FIRE targets are intermediate milestones on the way to full FI. Hitting 50% of your FI number is a major psychological boost, compound growth does more of the heavy lifting from there.
Debt-free except mortgage is another common milestone that frees cash flow for accelerated investing.
Calculate and track your net worth
List your assets and liabilities to get your current net worth, then compare investable assets to your FIRE target.
Use the net worth calculator for your snapshot, the FIRE calculator for your timeline, and the investment growth calculator to project where you will be in future years.
