About the Expected Net Worth Calculator
This expected net worth calculator applies the rule of thumb from Thomas Stanley and William Danko’s book The Millionaire Next Door: multiply your age by your pre-tax annual household income from all sources except inheritances, then divide by ten. The answer is the net worth someone of your age and income would be expected to have. The authors add that inherited wealth should be left out, so the calculator lets you subtract any inheritance from your net worth before comparing.
Compare it with your actual net worth to see which of the book’s groups you fall into. A prodigious accumulator of wealth (PAW) has at least twice the expected figure; an under accumulator of wealth (UAW) has half or less; everyone in between is an average accumulator (AAW). The calculator shows your ratio, the PAW and UAW thresholds and how far you are from the next level.
The formula is a blunt benchmark, not a target. It was built from surveys of established, mostly older households, so it is harsh on people in their twenties and early thirties who have had few years of earning, carry student loans or have just bought a home. Use it to track your trend over time rather than to judge a single year.
With the default inputs, the expected net worth is $540,000.00. Change any value above to recalculate instantly.
How to use the expected net worth calculator
- 1Enter your age.
- 2Enter total pre-tax household income for the year, excluding any inheritance.
- 3Add up your assets, subtract your debts and enter the resulting net worth.
- 4Read your expected net worth, your ratio and which accumulator group you fall into.
- 5Recalculate each year to see whether your ratio is improving.
Formula and method
Stanley and Danko’s rule multiplies your age by your realized pre-tax annual household income from every source except inheritances and divides by ten. Someone aged 45 earning $120,000 is therefore “expected” to be worth $540,000. Net worth means everything you own (cash, investments, retirement accounts, home equity, business equity) minus everything you owe; any inherited wealth you enter is subtracted so only self-built wealth is compared.
The book sorts households into three groups by comparing actual net worth with this expected figure. Prodigious accumulators of wealth have at least twice the expected amount, under accumulators have half or less, and average accumulators fall in between. The ratio output is simply your net worth divided by the expected value, so 2.0 or more is PAW and 0.5 or less is UAW.

Worked examples
Age 45, $120,000 income, $400,000 net worth
45 × $120,000 ÷ 10 = $540,000 expected. A $400,000 net worth is about 0.74× that, above the $270,000 UAW line but well short of the $1,080,000 needed to count as a prodigious accumulator.
Age 55, $90,000 income, $1.2 million net worth
55 × $90,000 ÷ 10 = $495,000. A $1.2 million net worth is about 2.42× the expected figure, comfortably above the $990,000 PAW threshold.
Age 32, $150,000 income, $60,000 net worth
32 × $150,000 ÷ 10 = $480,000. A $60,000 net worth is only 0.125× that, below the $240,000 UAW line — common for high earners early in their careers who are still paying off education or a home purchase.
Excluding an inheritance
50 × $100,000 ÷ 10 = $500,000. Of the $900,000 net worth, $300,000 was inherited, so only $600,000 counts — a ratio of 1.2 and average-accumulator status, $400,000 short of the $1,000,000 PAW line. Counting the inheritance would have shown a misleading 1.8.
Frequently asked questions
What is the Millionaire Next Door net worth formula?+
Multiply your age by your pre-tax annual household income (excluding inheritances) and divide by ten. The result is your expected net worth. Having twice that makes you a prodigious accumulator of wealth; half or less makes you an under accumulator.
What counts as income in the formula?+
Stanley and Danko used realized pre-tax household income from all sources — salaries, bonuses, business profit, interest, dividends, rental income and pensions — but excluded inheritances. Unrealized gains on investments are not income.
Is the formula fair for people in their 20s?+
Not really. It assumes years of earning and saving behind you, so a 25-year-old with student loans will almost always score as an under accumulator. Many people only use it from their mid-30s onward, or focus on whether the ratio rises each year.
Should home equity count toward net worth?+
Yes, standard net worth includes home equity (market value minus mortgage balance). Some people also calculate a version without their home to see how much liquid, income-producing wealth they have, which is a stricter test.
What does PAW and UAW stand for?+
PAW means prodigious accumulator of wealth — someone whose net worth is at least double the expected figure. UAW means under accumulator of wealth — net worth at or below half the expected figure. Average accumulators (AAW) are in between.
