Now we can calculate the percentage of disposable income that is discretionary as follows;
percentage of disposable income that is discretionary = (discretionary income ÷ disposable income) × 100
% discretionary income = (900 ÷ 2,920) × 100
% discretionary income = 90,000 ÷ 2,920
% discretionary income = 30.82%
Hence, 30.82% of the disposable income is calculated to be discretionary if the disposable income is $2,920 and the amount left after payment of fixed expenses is $900.
