Keep in mind that disposable income is different from total income. Total income is the amount of income before taxes and routine expenses are paid, while disposable income is the amount of income available after taxes and routine fees are paid.

Factors that affect disposable income include tax rates, debt, and inflation. The higher the tax rate, the smaller the disposable income you have. Likewise with debt, the greater the debt that must be paid, the smaller the available disposable income. 

Meanwhile, inflation can affect disposable income because it can cause prices for goods and services to rise, so that the cost of living that must be paid also becomes more expensive.

Disposable Income Formula

Disposable income has a simple formula that can be applied. Here is the formula you need to know.

Disposable Income = Total Income – Taxes – Routine expenses

To calculate the disposable income formula, you first need to know the total amount of income received over a period of time. Next, you’ll need to calculate the amount of tax you need to pay, which can usually be calculated with reference to the applicable tax rates in your country or region of residence.

After that, you need to calculate routine expenses such as living expenses, bills and debt repayments. These costs must be paid before disposable income can be calculated.

After all costs are paid, the amount of disposable income can be calculated by subtracting taxes and recurring expenses from total income. The remaining amount is disposable income that can be used for consumption and investment.

Example of How to Calculate Disposable Income

Suppose someone has a total income of IDR 10,000,000 per month. The applicable tax rate is 10% of total income. Living expenses and bills every month is IDR 5,000,000. Installment debt that must be paid every month is IDR 3,000,000.

So, an example of how to calculate available disposable income is as follows:

  • Total Income = Rp10.000.000
  • Tax = IDR 1,000,000 (10% of IDR 10,000,000)
  • Routine Expenses = Rp. 8,000,000 (Rp. 5,000,000 + Rp. 3,000,000)
  • Disposable Income = (Rp10.000.000 – Rp1.000.000 – Rp8.000.000) = Rp1.000.000

1. Effect of Tax on Disposable Income

Taxes are one of the most influential factors on disposable income. The higher the tax rate imposed, the smaller the available disposable income. Taxes can reduce the amount of money received by individuals or families, thereby affecting the ability to buy goods and services and save.

Debt can also affect disposable income. If someone has a debt that must be paid every month, then the amount of available disposable income will decrease. This can affect the ability to meet daily needs and invest for the future.

3. Effect of Inflation on Disposable Income

Inflation can also affect disposable income because it can cause the prices of goods and services to rise. The higher the inflation rate, the more expensive the cost of living must be paid. This can reduce the amount of disposable income available and affect the ability to buy goods and services.
