Savings Rate Definition: Gross vs Net, Personal vs Household Explained

The US Bureau of Labor Statistics Consumer Expenditure Survey consistently shows the top income quintile saving 25–30% of pre-tax income, while the bottom quintile saves 2–4% — sometimes negative. That 20-plus percentage point gap exists partly because of genuine income differences, but also because different people are measuring "savings rate" in completely different ways. Before you benchmark yourself against any survey data, you need to know exactly what you're measuring.

The core savings rate definition

A savings rate is the percentage of income that is not spent during a given period. The formula is straightforward:

Savings rate = (Income − Spending) ÷ Income × 100

The complication is that "income" and "spending" each have multiple valid definitions, and mixing them produces numbers that are incomparable across sources.

The three decisions you have to make before calculating your rate:

Gross or net income as the denominator
Personal or household as the unit of measurement
Which expenses count as "spending" versus "saving"

Get these wrong and you can make the same financial situation look like a 12% savings rate or a 22% savings rate, both technically correct, neither directly comparable to published benchmarks.

Gross vs net: why the denominator matters

The single biggest source of confusion in any savings rate definition is whether you divide by gross income (before tax) or net income (after tax and mandatory deductions).

Gross-based savings rate divides by your total pre-tax earnings. If you earn £60,000 gross, pay £12,000 in income tax and National Insurance, and save £6,000, your gross savings rate is 10%.

Net-based savings rate divides by take-home pay. In the same example, your net income is £48,000 and your net savings rate is 12.5%.

Neither is wrong — they measure different things. The ONS Living Costs and Food Survey in the UK and the BLS Consumer Expenditure Survey in the US both use disposable (after-tax) income as the baseline when reporting household saving ratios in their headline figures. The OECD household saving rate, which aggregates national accounts data, also uses net disposable income.

The practical implication: if you compare your gross-based personal savings rate to a survey benchmark that uses net disposable income, you will always appear to be saving less than you actually are relative to peers. How we calculate savings benchmarks at PathVerdict explains which income definition each national dataset uses, so comparisons stay consistent.

Personal vs household savings rate

A personal savings rate measures one individual's income and spending. A household savings rate covers everyone living under the same roof, pooling all income sources and all expenditure.

Most national surveys — the BLS CES, the ABS Household Expenditure Survey, StatsCan Survey of Household Spending, the CBS Household Budget Survey in the Netherlands, and others — collect household-level data. A single-person household and a dual-income couple are both "households," but their financial dynamics are entirely different.

This distinction matters when you self-benchmark. If you are a single earner on £45,000 comparing your rate to ONS data for a two-adult household with combined income of £80,000, the comparison is structurally skewed. Households with multiple earners tend to show higher saving rates partly because fixed costs (rent, utilities) are shared across a larger income base.

The savings rate in London illustrates this clearly: a single professional paying £1,950/month in median rent faces a far steeper path to a competitive savings rate than a couple splitting that same rent, even at identical individual incomes.

What counts as saving vs spending

The third variable in any savings rate definition is which cash flows go in the numerator.

Common items that are genuinely ambiguous:

Pension/401(k) contributions: These are deferred consumption, not current spending. The BLS CES includes employer-sponsored pension contributions in its saving measure. If you exclude your pension contributions from your savings calculation but the survey benchmark includes them, your rate looks artificially low.
Mortgage principal repayment: Paying down a mortgage builds equity — it is a form of saving. Many household budget surveys classify principal repayment as saving, not housing expenditure. Rent, by contrast, is pure expenditure.
ISA or brokerage account transfers: Straightforward saving, but only if the money stays invested and is not drawn down within the same period.
Extra loan repayments: Reducing debt increases net worth, which is economically equivalent to saving.

The Swiss FSO HABE and the French INSEE Budget de Famille both include net acquisition of financial assets (including pension saving) in their household saving figures. If you define saving only as cash sitting in a bank account, you will consistently understate your rate relative to these benchmarks.

For a practical working definition that matches survey data: savings = income minus all non-capital expenditure, including pension contributions and mortgage principal repayment, but excluding debt interest, which is a cost.

How savings rates vary across income, city, and country

Published survey data shows savings rates are not evenly distributed. Some patterns from the national datasets:

By income: The top quintile in both the US (BLS CES) and UK (ONS LCF) saves at roughly 4–6× the rate of the median quintile. The bottom quintile frequently dissaves — spending more than income through drawdown of assets or borrowing.
By city: High-cost cities compress savings rates even at above-average incomes. The savings rate in New York reflects housing costs that run significantly above US national medians, which mechanically reduces the gap between income and spending for residents at similar income levels to lower-cost cities.
By country: OECD data shows Swiss and Swedish households saving at higher rates (often 15–20% of net disposable income) than US or UK households (closer to 5–10% in recent years), partly reflecting institutional pension system design and partly cultural spending patterns captured in the SCB HEK and Swiss HABE surveys.

If you want to understand what's a good savings rate for your specific income level, country, and city rather than a global average, the comparison has to account for all of these variables.

Frequently asked questions

Is savings rate calculated on gross or net income?

It depends on the source. Most official national household surveys — including the ONS Living Costs and Food Survey and the BLS Consumer Expenditure Survey — report savings rates relative to net disposable income (after tax). The OECD household saving ratio also uses net disposable income. When calculating your own rate for benchmarking purposes, use the same income definition as the dataset you are comparing against.

Does my pension contribution count in my savings rate?

Yes, in most survey methodologies. Contributions to employer pensions, 401(k) plans, or equivalent defined contribution schemes are treated as saving, not spending, in the BLS CES and most European household surveys. Excluding pension contributions understates your savings rate relative to published benchmarks.

What is a household savings rate vs a personal savings rate?

A personal savings rate covers one individual's income and expenditure. A household savings rate covers all members of a dwelling — partners, dependants, and any other residents whose income and spending are pooled. National surveys use household-level data. If you live in a multi-income household, your household savings rate will typically differ from your personal savings rate.

Can a savings rate be negative?

Yes. A negative savings rate means spending exceeds income during the period, funded by debt drawdown or asset liquidation. BLS CES data shows the bottom income quintile in the US regularly recording negative saving rates in aggregate. This is not unusual for households in low-income periods or those with high fixed obligations relative to income.

Your savings rate calculation is only useful if the definition behind it is consistent with the benchmark you are comparing against. Gross versus net income, individual versus household unit, and pension inclusion all shift the number materially.
