Quick Answer
Single people or couples can budget around 4 to 5 percent of taxable earnings, with 10 percent as a practical upper limit. Families use 4 percent per adult and 1.5 percent per child, capped at 20 percent.
How to Calculate
- Choose the household type.
- Enter taxable monthly earnings.
- For families, enter the number of adults and children.
- Click Calculate.
Formula
Single / couple = taxable earnings x 4 percent
Family = taxable earnings x (4 percent x adults + 1.5 percent x children)
Family cap = taxable earnings x 20 percent
Worked Examples
Example 1: 5839 taxable earnings gives a minimum grocery budget of 233.56 for a single person.
Example 2: A family of 2 adults and 2 children uses the adult and child percentages, then applies the cap if needed.
Example 3: Higher earnings do not automatically mean a higher percentage budget, because the calculator keeps the cap in mind.
