Net Worth: Your Personal Balance Sheet

The budget from Module 1 is your income statement — flows per month. This module builds the other financial statement, the one that answers “how am I actually doing?”: the balance sheet.

If you’ve read the credit models track, this is exactly the lens a bank puts on a company before lending to it — and, through your credit file, a compressed version of the lens it puts on you. Solvency isn’t about how much flows through your hands; it’s about what’s left when the flows stop.

Why net worth beats income as a scoreboard

Income is how fast you’re running; net worth is where you actually are. Two people earning the same $50,000 a month can be in opposite financial universes — one with $800,000 accumulated and no debt, another with credit-card balances and nothing saved. High income with zero accumulation is a treadmill, and it’s invisible until you write the balance sheet down.

Net worth is also the honest judge of every strategy in this track: budgeting, sinking funds, debt payoff, and investing all exist to move this one number. Track it monthly and the feedback loop closes — you see the March vacation, and you see the compounding start to outrun your contributions a few years in.

Direction matters more than level. A negative net worth early on (student debt, a car loan, thin savings) is a starting point, not a verdict. What matters is the slope.

What counts, and at what value

The rules that keep the number honest:

• Cash and near-cash: checking, savings, CETES — face value. Easy.
• Investments: brokerage/ETF balances at market value. Don’t smooth them; volatility is real.
• Retirement money counts — fully. The single most common omission in Mexico is the AFORE balance. It’s your money, it’s often a household’s largest asset, and it appears on your AFORE statement three times a year (or anytime in the app). Add PPRs and any foreign retirement accounts too.
• Your car: at realistic resale value, not what you paid. It depreciates — that’s precisely the kind of truth the balance sheet exists to tell.
• Your home, if you own it: at a conservative market value, updated maybe yearly. And its mortgage sits on the other side, at the current payoff balance. Home equity — value minus mortgage — is often a family’s biggest asset, which is an argument for honesty in the estimate, not optimism.
• Liabilities at today’s payoff balance: mortgage, car loan, credit cards (the statement balance you’d need to pay off, not the minimum), personal and student loans, informal debts.
• Skip the fuzzy stuff. Furniture, electronics, clothes — resale value is negligible and estimating it just flatters the number. Exception: genuinely sellable items (jewelry, instruments, equipment) at pessimistic values.

The monthly ritual

Once a month — same day you reconcile the budget — write down three numbers: total assets, total liabilities, net worth. The Net Worth sheet in the downloadable planner keeps a 12-month log with a chart, and the month-over-month change column is the interesting part:

• Change ≈ what you saved + investment returns − new debt. In early years, your savings rate dominates the change. Later, market movements will swamp it in both directions — that’s normal and means compounding has taken over.
• A falling month isn’t failure. Markets drop; cars get bought. The question is the 12-month trend.
• Watch the ratio, too: liabilities ÷ assets. Banks think in these terms when they underwrite you (Module 4 takes the borrower’s-side view of debt); below ~50% and falling is a healthy trajectory for a household carrying a mortgage.

One warning about the psychology: net worth is a scoreboard, not a competition. The useful comparison is you-versus-you-last-year. Everything else is noise with better marketing.

Next: the liability side of this balance sheet deserves its own module — Module 4: Debt, and the interest rate as the enemy.
