Net worth & budgeting: published formulas + calculators

As of Oct. 15, 2026

Net worth is what you own minus what you owe. A budget leftover is what you take in minus what you spend. Public guides from Investor.gov (SEC), the CFPB, and FDIC Money Smart teach both in plain steps. This page shows those published definitions with dates, a situation picker for what to do next, and two calculators that only do the math you enter.

Not financial advice. This page republishes what Investor.gov (SEC), the CFPB, and FDIC Money Smart publish about net worth and budgeting, with dates. It does not tell you how much to save, which debts to pay first, or where to put money. The calculators only subtract numbers you type in. Confirm account terms and insurance coverage with your bank or credit union.

Your roadmap

  1. Write a net worth snapshot: list assets and liabilities, subtract (Investor.gov; FDIC Money Smart Module 10). Update about once a year.
  2. Track one month of income and expenses (CFPB monthly budget steps; FDIC Money Smart Module 4 spending and saving plan).
  3. If expenses exceed income, cut or raise income until the leftover is zero or positive (CFPB).
  4. If you have little emergency cash, size a cushion using published ranges on the emergency-fund page.
  5. If high-interest debt is large, use the debt-payoff calculator or debt-relief options page.
  6. If you have a leftover, set an automatic transfer ("pay yourself first" — Investor.gov) and compare savings accounts.
  7. Optional: try a budgeting app to keep the habit; compare apps only after the math is clear.

What net worth means

Investor.gov: a net worth statement lists what you own (assets) on one side and what you owe (liabilities or debts) on the other. Subtract liabilities from assets. If assets are larger, you have a positive net worth; if liabilities are larger, you have a negative net worth. Update the statement every year.

FDIC Money Smart Module 10 key takeaway (paraphrased; see FDIC downloads for full curriculum): net worth is a good measure of financial stability. Calculate it by subtracting liabilities (money you owe others) from assets. An asset is something you own that has value; a liability is something you owe; equity is the value of an asset minus the liability related to that asset.

Budgeting as public guides describe it

CFPB monthly budget tool: (1) list your income, (2) list your expenses, (3) subtract total spending from total income. If income is more than expenses, you have money left to save or spend. If expenses are more than income, look at the budget to find expenses to cut. Educational and information purposes only — not a replacement for advice from a qualified professional.

FDIC Money Smart Module 4 (Your Spending and Saving Plan): build a monthly spending and saving plan that compares income and expenses, shows where money goes, and supports adjustments so money can meet your goals. When money is short, the module discusses prioritizing spending. Outcomes when you compare totals: income covers expenses, income exceeds expenses (room to save or spend), or expenses exceed income (need to cut or raise income).

Investor.gov: many people build a saving and investing habit by paying themselves first — for example, having the bank automatically deposit money from a paycheck into a savings or investment account. If you are spending all your income and never have money to save or invest, start by cutting back on expenses.

About 50/30/20 and similar percentage splits: those rules are common in consumer media. This page does not attribute a fixed percentage split to CFPB or FDIC. We stick to the cash-flow and spending-and-saving methods those agencies publish.

FAQ

What is net worth?

Investor.gov: list assets (what you own) and liabilities (what you owe), then subtract liabilities from assets. Positive if assets are larger; negative if debts are larger. FDIC Money Smart Module 10 uses the same assets − liabilities formula.

How do I make a simple budget?

CFPB monthly budget tool: list income, list expenses, subtract spending from income. If income is higher, you have money left to save or spend; if expenses are higher, look for cuts. FDIC Money Smart Module 4 builds a monthly spending and saving plan the same way.

How do the calculators work?

Net worth = total assets − total liabilities (category totals you enter). Leftover = monthly income − monthly expenses. Optional savings rate = leftover ÷ income. Formulas are shown on the page; no product recommendations.

What should I do first if money is tight?

If expenses exceed income, CFPB says find expenses to cut. FDIC Money Smart Module 4 discusses prioritizing when money is short. Then use the situation picker on this page for the next education step (emergency fund, debt tools, or savings comparison).

Is this financial advice?

No. We republish Investor.gov, CFPB, and FDIC Money Smart material with dates and do arithmetic on numbers you type. We do not tell you how much to save or which products to buy.

Estimates, not financial advice. Taxes, insurance, PMI and fees vary by lender, county and city; confirm with your lender, dealer and state agency before acting.
