Quick answer

The grocery budget calculator suggests a weekly and monthly grocery budget from your income and household – a minimum and a comfortable upper limit – using the common rule of spending about 4–10% of income on food at home.

Financial planners often suggest food at home should be around 5–15% of take-home pay, depending on household size and local prices. U.S. households spent on average about 7–8% of income on groceries (USDA ERS). Planning meals and shopping with a list helps stay within budget.

How to use the Grocery Budget Calculator

  1. Household
  2. Monthly take-home income
  3. Adults
  4. Children

Results update as you type, and every field accepts the units shown in its menu.

How it works

Choose your household type and enter monthly take-home income, the number of adults and children.

Tips

  • Use the figures from your own bills and product labels – prices and appliance ratings vary widely.
  • Look at yearly totals: small daily costs add up and make it easier to compare options.
  • Round quantities up to whole packs, rolls or bulbs when you shop.
  • Re-check the numbers when prices change; most results scale directly with the unit price.

Common mistakes to avoid

  • Confusing watts (power) with watt-hours or kilowatt-hours (energy).
  • Comparing prices without bringing them to the same unit first.
  • Ignoring one-off costs such as installation, delivery or replacement parts.
