Net Worth Calculator
Assets minus debts with a full breakdown of each side.
What it does
Net worth compresses a whole balance sheet into one number: assets minus debts. It rises with savings, paydowns, and market gains, and falls with borrowing, losses, and big spending.
The tool above totals cash, investments, and property against mortgage and other debts. It returns the net figure with both sides itemized.
Liquidity matters beside the total. Home equity looks great on paper but converts slowly and costly, while cash and brokerage funds deploy at once. Two equal net worths can live very different emergencies.
Young renters often start negative with student debt, which is normal, not failure. The trend line across quarters tells the story: steady climbs mean the plan works regardless of the starting point.
How to use
- List cash at statement values.
- Mark investments to market, not purchase price.
- Price property conservatively.
- List every debt balance, then retrack quarterly.
Formula
- assets
- Everything owned at realizable value.
- debts
- Everything owed, balances today.
Pensions and Social Security value complexly and usually stay out of DIY math. Count vested account balances and skip promised streams.
Worked example
Example: cash 15k, investments 80k, home 350k, debts 290k
Cash 15,000, investments 80,000, property 350,000, mortgage 280,000, other debts 10,000.
- Assets: 15,000 + 80,000 + 350,000 = $445,000.00.
- Debts: 280,000 + 10,000 = $290,000.00.
- Net: 445,000 - 290,000 = $155,000.00.
- Equity share: (350,000 - 280,000) / 155,000 = 45% of net in the house.
Reference table
| Age | Typical band | Notes |
|---|---|---|
| Under 35 | Low to negative | Student debt phase |
| 35 to 44 | Growing | Equity and 401k build |
| 45 to 54 | Peak growth | Highest earnings years |
| 55 plus | Highest | Compounding plus paydowns |
Limits
- Estimates, not appraisals. Markets move both sides.
- Ignores taxes due on selling assets.
- Human capital and pensions excluded.
- Currency and inflation shift meaning over time.
Common mistakes
- Pricing the house at listing fantasy.
- Forgetting cards and car loans on the debt side.
- Counting gross investments before capital taxes.
- Checking daily and reacting to noise.
- Comparing across ages and cities blindly.
Try it yourself
Quick checks. Answers sit tucked under each question.
Assets 200k, debts 250k. Net?
200,000 - 250,000 = -$50,000. Negative is common early.
Paying $5,000 of cards changes net how?
Cash falls 5k, debts fall 5k. Net unchanged today, but interest stops.
Questions
What counts as an asset?
Cash, investments at market, property at sale value, business stakes. Not salaries or pensions.
Is home equity real wealth?
Yes but illiquid. It counts while spending plans should lean on liquid funds.
Can net worth go negative?
Yes, mainly young with student debt. Trend matters more than the sign.
How often should I update?
Quarterly. Monthly market noise drowns the signal.
Do cars count?
At resale value minus loans. Most cars drag net worth down.
What is a good net worth by 40?
Rules of thumb say multiples of income, but city and career bend them. Track your own slope.
