> 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.

## Inputs

- Household
- Monthly take-home income
- Adults
- Children

## Results

- Minimum monthly grocery budget
- Upper monthly limit
- Minimum per week
- Share of income (minimum)

## Formula

```
Individual / couple: minimum = 4% of income, upper = 10%
Family: 4% × income × adults + 1.5% × income × children, capped at 20% of income
```

## Explanation

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

- **Household**
- **Monthly take-home income**
- **Adults**
- **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.
