How to Calculate Savings Rate in Economics

Understanding your personal savings rate is fundamental to both macroeconomic analysis and personal financial health. In economics, the Personal Savings Rate measures the fraction of disposable income that is saved rather than spent on consumption. It acts as a key indicator of financial stability and future consumption potential.

The Economic Formula

The Bureau of Economic Analysis (BEA) and standard economic textbooks define the personal savings rate using a specific flow of funds logic. It is calculated by first determining Disposable Personal Income (DPI), then subtracting personal outlays.

Savings Rate = (Personal Savings / Disposable Personal Income) × 100

Where:

  • Disposable Personal Income (DPI) = Gross Personal Income − Personal Current Taxes
  • Personal Savings = DPI − Personal Outlays (Consumption)

Step-by-Step Calculation Guide

Step 1: Determine Gross Personal Income

This includes all sources of income before any deductions. In an economic context, this includes wages, salaries, proprietor's income, rental income, personal income receipts on assets (interest and dividends), and personal current transfer receipts (like government benefits).

Step 2: Subtract Personal Taxes

To find the money actually available for spending or saving, you must subtract "Personal Current Taxes." This includes federal, state, and local income taxes, as well as contributions to government social insurance (like Social Security and Medicare taxes).

Result: This gives you your Disposable Personal Income (DPI).

Step 3: Subtract Personal Outlays

Personal outlays essentially mean consumption. It is the money spent on goods (durable and non-durable) and services. Note that in strict economic definitions, purchasing a house is often considered investment, but for simpler personal finance models, rent/mortgage interest is an outlay, while principal repayment might be considered savings (equity buildup). For this calculator, include all your living expenses and consumption.

Result: This gives you your Personal Savings (in absolute currency).

Step 4: Divide and Convert to Percentage

Finally, divide your Personal Savings by your Disposable Personal Income and multiply by 100 to get the rate.

Calculation Example

Let's look at a practical example of a household to see how the numbers work:

Category Amount Notes
Gross Income $100,000 Wages + Dividends
(-) Taxes $20,000 Income Tax + SS
= Disposable Income (DPI) $80,000 (A)
(-) Consumption/Outlays $68,000 Rent, Food, Travel, etc.
= Personal Savings $12,000 (B)

Using the formula:

Savings Rate = ($12,000 / $80,000) × 100 = 15%

Why is the Savings Rate Important?

Macroeconomic Perspective

On a national level, the savings rate indicates the health of the economy. A high savings rate means more capital is available for banks to lend to businesses for investment (capital accumulation). However, if the savings rate is too high, it might indicate a "paradox of thrift," where low consumption slows down economic growth.

Personal Finance Perspective

For individuals, the savings rate is the primary driver of wealth accumulation. It determines how quickly you can achieve financial independence. A higher savings rate reduces the time required to retire because you are living on a smaller percentage of your income (requiring a smaller nest egg) while simultaneously adding more to your savings.

Frequently Asked Questions

Does 401(k) contribution count as savings?

Yes. In economic terms, money diverted to retirement accounts is income that is not consumed. Therefore, it is part of your personal savings. When calculating your rate, ensure your Gross Income includes these contributions, and your "Outlays" do not include them.

What is a good personal savings rate?

While the U.S. national average often hovers between 5% and 10%, financial planners typically recommend aiming for at least 20%. Proponents of the FIRE (Financial Independence, Retire Early) movement often aim for savings rates of 50% or higher.

Is paying off debt considered saving?

Economically, paying down the principal balance of a loan increases your net worth and can be considered saving. However, the interest portion of a loan payment is considered an expense (service consumption). Therefore, principal payments add to your savings rate, while interest payments reduce it.
