### How to use the Back to School Calculator

- **Total budget**
- **Clothing and accessories**
- **Shoes**
- **Electronics**
- **School supplies**
- **Other**

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

### How it works

Enter your total budget and the amount you plan to spend in each category.

### 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.
