Ask ten households what they save and you will get ten different definitions. Some count only the 401(k). Some count the employer match but not the brokerage account. Some count the mortgage principal, the college fund, and the emergency reserve they dipped into twice last year. The number that comes back is almost always flattering, and almost always wrong.
We use one standard: 20% of gross household income, saved every year, measured before taxes and before lifestyle. It is deliberately demanding. It is also the single most reliable predictor we see of whether a family reaches financial independence on their own terms rather than on a schedule set by circumstance.
Why gross, not net
Net income is a moving target. It shifts with withholding elections, bonus timing, equity vesting, deductions, and the particular tax year you happen to be in. Measuring savings against net income lets the denominator shrink whenever taxes rise, which makes the rate look better precisely when the household is under more pressure. Gross income does not flatter anyone. It is the number your earning power actually produced, and it is the honest basis for asking what share of that power you converted into future freedom.
There is a second reason. Taxes are a planning variable, not a fixed cost. When savings are measured against gross income, tax efficiency becomes visible as part of the savings conversation — pre-tax versus Roth, asset location, deferral timing, entity structure for owners. Measure against net and you have quietly excused the largest controllable expense in most high-income households.
What counts
Retirement plan contributions, both yours and the employer match. Taxable brokerage investing. Cash accumulation earmarked for the plan rather than for next year's spending. Debt principal reduction on non-mortgage obligations counts as a form of balance-sheet savings, and mortgage principal counts in most cases, provided the household is not treating home equity as its only asset. What does not count: the money that leaves your checking account and comes back as a vacation, a vehicle, or a renovation. Those may be excellent uses of income. They are not savings.
How high earners drift
The uncomfortable pattern is that savings rates tend to fall as income rises. Someone earning $150,000 who saves $30,000 is at the standard. The same person at $400,000 typically saves more in dollars and less in percentage, because the increase arrived gradually and lifestyle absorbed it without a decision ever being made. Every raise is a fork in the road that most people pass without noticing.
The drift is rarely caused by extravagance. It is caused by fixed commitments — a larger mortgage, private tuition, a second property, a family obligation — each defensible in isolation, each permanent, and each subtracting from the flexibility that made the higher income valuable in the first place. By the time the pattern is visible on paper, unwinding it requires changing where you live or how your children are educated. That is a hard conversation to have at 55 and an easy one to avoid at 40.
Structure, not sacrifice
Households that hold the standard almost never do it through willpower. They do it through structure: savings that clear the account before spending begins, raises that are split by rule rather than by feeling, bonuses with a predetermined destination, and a plan that names the accounts before the money arrives. The discipline is in the design, not in the monthly decision.
If you are below the standard, the gap is worth measuring honestly before it is worth closing. Most households we work with find that the distance between where they are and 20% is smaller than they feared, and that it closes through sequencing and tax efficiency rather than through giving anything up. That is the work of planning.
