Private Savings Calculator — Household & Macro Savings
Private savings equals disposable income minus consumption. Enter gross income, effective tax rate, and spending to get private savings and your savings rate. Add government spending to also see public savings (a surplus or deficit) and national savings.

How does this calculator work?
Private Savings = Gross Income − Taxes − Consumption (or Disposable Income − Consumption). Public Savings = Tax Revenue − Government Spending. National Savings = Private + Public. The private savings rate = Private Savings ÷ Disposable Income × 100. Negative private savings means the household or sector is spending beyond its after-tax income.
Formula
How this is calculated
In macroeconomics, private savings is the portion of disposable income (gross income minus taxes) not spent on consumption. It is the fundamental source of loanable funds for business investment. The formula S_private = Y − T − C follows directly from the household budget identity.
Public savings equals tax revenue minus government spending (T − G). When T > G the government runs a surplus and contributes positively to national savings; when T < G it runs a deficit and reduces national savings. National savings is simply private plus public savings: S_national = (Y − T − C) + (T − G) = Y − C − G, or equivalently GDP minus total consumption and government spending.
For household-level analysis, treat Y as gross household income, T as all income and payroll taxes paid, and C as total annual spending (housing, food, transport, etc.). The private savings rate (S/Disposable Income) is the clearest measure of saving behaviour — the OECD average household savings rate is around 5–12% in most developed economies, though it varies significantly by country, income group and economic conditions. A negative private savings means the household is drawing down assets or taking on debt.
Frequently asked questions
Private savings is what households and businesses save after taxes and consumption. Public savings is government revenue minus government spending (positive = surplus, negative = deficit). National savings is their sum. In equilibrium, national savings equals domestic investment plus net capital outflow — it measures the economy's total resources available for investment.
A commonly cited target is 10–20% of disposable income, though it depends heavily on life stage, income level, and financial goals. Early-career workers may save less; those approaching retirement should aim higher. The OECD household savings rate for most developed countries has ranged from around 5–20% in recent years, with significant variation by country.
Negative private savings means households are spending more than their disposable income — funding the gap by running down existing assets (savings accounts, investments) or by borrowing. This is unsustainable in the long run but is normal in certain periods, such as after job loss, in retirement, or during economic downturns when consumption is maintained through borrowing.
