Net Worth Calculator
Net worth is the single most important number in personal finance. It tells you exactly where you stand: total assets minus total liabilities equals the wealth you actually own. This calculator breaks down each category so you can see not just your net worth, but where it comes from — and where debt is dragging it down.

Net Worth Calculator
Assets Minus Liabilities — Your Complete Financial Snapshot
📐 Formula & Method
Net Worth Formula
This is the foundational equation of personal finance. Every dollar of assets you own, minus every dollar of debt you owe, equals your net worth. It can be negative — especially early in life with student loans and a new mortgage — and that is normal.
Home Equity Component
Your home's contribution to net worth is only the equity — the portion you actually own. A $400,000 home with a $320,000 mortgage balance contributes $80,000 to net worth, not $400,000.

💡 Key Insights
-
Net worth — not income — is the most accurate measure of financial health. Two people earning the same can have wildly different net worths.
-
A common benchmark (Stanley's "PAW formula"): Expected Net Worth = Age × Income / 10. Hit this consistently and you're ahead of the average.
-
Fidelity's target multiples: 1× salary by 30, 3× by 40, 6× by 50, 8× by 60, 10× by 67. Helpful directional guides, not rigid rules.
-
Negative net worth is normal in your 20s/30s if you have student loans + a new mortgage. The trajectory matters more than the absolute number.
-
Median US household net worth is ~$192,000 (Fed 2022). UK median is ~£302,500 (ONS 2020) — heavily influenced by property values.
🧮 Worked Examples
Mid-career US household
Age 42, dual-income family with home, 401(k), and a mortgage.
Early-career UK saver
Age 28, single, renting, building an ISA.
📊 How to Interpret Your Result
Debt-to-asset ratio under 30%
Healthy leverage. You own substantially more than you owe.
Debt-to-asset ratio 30–50%
Moderate leverage — common with a mortgage. Watch unsecured debt levels carefully.
Debt-to-asset ratio above 50%
High leverage. Prioritise paying down high-interest debt before adding more assets.
⚠️ Common Mistakes to Avoid
Using your home's purchase price instead of current market value.
Fix: Always use estimated current market value. Tools like Zillow, Redfin, Zoopla, or a recent appraisal give realistic figures.
Forgetting pension/SIPP/workplace pension.
Fix: Retirement balances absolutely count — include the current value of every retirement account.
Counting your car at purchase price.
Fix: Vehicles depreciate fast. Use a current resale estimate (KBB, Auto Trader).
Counting UK Plan 2 student loans as full debt.
Fix: Plan 2 loans are income-contingent and write off after 30 years — many advisers exclude them from net worth.

What Is Net Worth and Why Does It Matter?
Net worth is the clearest measure of financial health — cleaner than income, cleaner than savings rate. Two people earning identical salaries can have wildly different net worths depending on whether they've been accumulating assets or debt. A doctor earning $300,000/year with $400,000 in student loans and a leveraged lifestyle may have a lower net worth at age 35 than a teacher earning $60,000/year who has been consistently saving and investing since their twenties.
According to the US Federal Reserve's Survey of Consumer Finances (2022), median US household net worth is approximately $192,000 — but the distribution is highly unequal. The top 10% hold median net worth of $1.9M+, while the bottom 50% have a median of just $51,000. In the UK, the Office for National Statistics reports median household net worth of approximately £302,500 (2020) — with property accounting for the largest component for most households.
Net worth benchmarks by age (US, rough guidelines): By 30, aim for 1× annual salary. By 40, aim for 3×. By 50, aim for 6×. By 60, aim for 8×. By 67, aim for 10×+ to support retirement. These are targets, not rules — the key is a consistent positive trajectory, not a fixed number.
The fastest way to build net worth is to simultaneously grow assets (invest in equities and property) and eliminate high-interest liabilities (credit card debt at 20%+ APR is the enemy of wealth). Paying off a credit card with 20% APR is equivalent to earning a guaranteed 20% return — better than almost any investment. Once high-interest debt is gone, redirect cash flow to tax-advantaged accounts (401k match, Roth IRA, ISA, SIPP) before taxable investments.
🔬 Methodology & Accuracy
Formula: Net worth = Total Assets − Total Liabilities. Home equity = current market value − remaining mortgage balance. Investable net worth excludes the primary residence as it's an illiquid asset.
