Bills and Budgets
Understanding bills and budgets is an important life skill. A bill is a written record of items purchased along with their quantities and prices. A budget is a plan for how to spend a fixed amount of money.
In Class 5, you learn to read bills, calculate totals, verify amounts, and prepare simple budgets. These skills help manage money wisely — whether it is your pocket money, a school event budget, or a shopping trip.
What is Bills and Budgets - Class 5 Maths (Money)?
Bill: A bill (or invoice) is a detailed list showing items bought, quantity of each item, rate (price per unit), and the total amount. The bill may also show discounts, taxes, or delivery charges.
Budget: A budget is a plan that shows expected income and planned expenses. A good budget ensures that expenses do not exceed the available money.
Parts of a bill:
- Item name — what was purchased
- Quantity — how many units were bought
- Rate — price per unit
- Amount — quantity × rate for each item
- Grand total — sum of all amounts
Bills and Budgets Formula
Amount for each item = Quantity × Rate per unit
Grand Total = Sum of all item amounts
Balance = Total money available − Total expenses

Example 3: Example 3: Verifying a Bill
