Discretionary income is the amount of income that is left for an individual, household, or business after paying the necessary or essential expenses.
Necessary expenses are expenses that are required either by law or are needed for survival.
Discretionary income can be spent on non-essential goods and services, vacations, luxury items, etc.
Understanding Discretionary Income
Discretionary income is the primary driver for a market-based economy. Since the overall economy’s success is based on the growth of production and spending, a key component of a flourishing economy is increasing discretionary income.
The three ways that discretionary income can be allocated include:
When individuals and households spend more of their discretionary income on goods and services, vacations, luxury items, and other nonessential items, money is funneled towards businesses that provide those goods and services.
The businesses can then reinvest the earnings to grow their operations, which leads to more jobs and further increases in discretionary income. Also, businesses can return the earnings to shareholders, which increases the shareholders’ discretionary income.
When individuals and households invest more of their discretionary income in various types of investments, it provides capital for businesses as well. The capital can be used to expand the businesses and lead to more jobs, as well as increased discretionary income.
The investments are expected to generate some sort of return to the investor, which increases the investor’s discretionary income later.
When individuals and households save more of their discretionary income, they usually do so through a bank or other financial institution.
A part of the banks’ business models is taking money from depositors/savers, keeping it safe for them, and lending out a portion of it to those who need the funds now. Borrowers can be individuals or businesses that usually use the funds for activities that further grow the economy.
Impact on the Economy
The economy will benefit from greater spending as opposed to saving, and central banks influence consumers’ propensity to consume or spend through monetary policy.
An expansionary monetary policy that features low interest rates will incentivize individuals and households to save less and spend more.
On the other hand, a tight monetary policy that features higher interest rates will incentivize individuals and households to save more and spend less.
Discretionary Income vs. Disposable Income
Discretionary income is the income available after paying the necessary or essential expenses.
Examples of necessary expenses for an individual include:
Certain forms of insurance
Rent or mortgage payments
Utility or other bill payments
Examples of necessary expenses for a business include:
Paying employee salaries
Interest expenses to debt holders
Disposable income, on the other hand, refers to the income that is left after paying taxes. This is the take-home income that is available to pay for both essential and nonessential expenses.
An individual receives an annual gross (pre-tax) income of $50,000. He pays a 30% tax rate over the year and incurs essential expenses of $2,000/month for bills, rent, and groceries, etc. What is his disposable income?
The amount of taxes paid is calculated as pre-tax income multiplied by the tax rate, as shown below:
$50,000 x 30% = $15,000
After taxes, the amount of disposable income is $35,000 ($50,000 – $15,000).
What is his discretionary income?
The amount spent on essential expenses over the year is the monthly expenses multiplied by twelve months in the year.
$2,000 x 12 months = $24,000
After taxes and essential expenses, the discretionary income is $11,000.
