What is disposable income?
After income taxes have been subtracted, we know disposable income as disposable personal income (DPI), is the amount of money that an individual or family has to spend or save. We can see disposable personal income extensively through the macro level as one of the primary economic indicators. And we use it to assess the overall status of the economy.

Disposable income is the source of a variety of statistics and economic indicators. Economists, for example, utilize the disposable income to compute measures like discretionary income, personal savings rates, marginal propensity to spend (MPC), and marginal propensity to save (MPS).

Disposable income formula
The calculation of disposable income follows a simple formula; deduct personal taxes and other legal responsibilities from personal income and add any government transfers:

Disposable \; Personal \; Income = Personal \; Income - Government\; Taxes + \\ Government\; Transfers.
DisposablePersonalIncome=PersonalIncome−GovernmentTaxes+
GovernmentTransfers.


How to calculate disposable income?
Follow these procedures to determine your discretionary income:

Determine your yearly gross revenue. When you acquire a full-time job, your yearly gross income indicate your offer letter.
Make a note of all tax rates. When determining your disposable income, make a note of your federal, state, and local tax rates. Because of that you can see exactly how much money you have available for spending or saving.
Calculate your taxable income by multiplying your yearly gross income by the tax rate.
Subtract the amount of tax from your annual gross income. You acquire your disposable income when you reduce the tax amount from your original yearly income. You can save this money or spend it.
Disposable income definition economics
The part of an individual’s income over which the receiver has total control referred to as disposable income. It’s difficult to give a precise general definition of revenue. Wages and salaries, interest and dividend payments from financial assets, and rents and net profits from enterprises are all income examples.

In most circumstances, capital gains on real or financial assets should be included as income. At least to the extent that they improve spending capacity. Even if the item is not sold and the increase in spending power is not used, it may count such benefits. Furthermore, receipts that are not in the form of currency (revenue in-kind) may be included.

Disposable income vs. discretionary income
Disposable income and discretionary income are important economic indicators that we use to assess the financial soundness of businesses and people.

Individuals and corporations generate revenue through selling products or services or investing in assets such as Individual retirement accounts (IRAs). Pensions and Social Security are two more sources of income. We may use this money to cover day-to-day expenses and requirements or spend it on items that people want rather than need.

There are, however, important distinctions between disposable and discretionary income. We’ll go through the differences in this post, as well as how to determine your discretionary income. Knowing your discretionary income will help you calculate your student loan payback using an income-based repayment plan if you have one.
