What is Net Disposable Income?
Net Disposable Income refers to the amount of money an individual or household has left after paying all mandatory taxes and deductions. It represents the actual spending power available for consumption, savings, investment, and discretionary expenses.
Definition
Net Disposable Income is the portion of income that remains after subtracting taxes (such as income tax, social security contributions, and mandatory levies) from total personal or household income.
Key takeaways

Formula
Net Disposable Income = Gross Income – Taxes and Mandatory Deductions

Net Disposable Income = 10,000 – 2,000 = P8,000
