KS3 citizenship: budgeting and planning spending

In Key Stage 3 citizenship, pupils learn why budgeting matters and how to do it. A budget is a plan that compares the money coming in with the money going out, so that people can cover what they need, save for what they want and avoid running out. Pupils practise with realistic scenarios, so that they can manage their own money day to day and plan for future needs.

Budgeting, explained

A budget is a plan for a period of time, usually a week or a month. It lists income, which is the money coming in, and expenditure, which is the money going out. If income is bigger than expenditure there is a surplus, which can be saved. If expenditure is bigger there is a deficit, which means the person has to cut back, earn more or borrow. Budgeting is not only for people who are short of money. Households, businesses, charities and governments all do it, because planning is easier than reacting.

Pupils learn to sort spending into types. Fixed costs stay the same each time, such as a phone contract or a subscription. Variable costs change, such as food, travel and leisure. Some costs are irregular, such as birthday presents, school trips, a replacement pair of shoes or a repair, and these are easy to forget. They also separate needs, the things you must have, from wants, the things you would like, and discuss why people’s lines between these can differ. Many people treat saving as a regular item in the budget, not as whatever is left over.

The usual method is simple. List income. Record what you actually spend for a few weeks, in a notebook, a spreadsheet or from a bank statement, because people often misjudge their spending. Set goals, such as a particular purchase and a date. Compare income with spending and adjust. Review regularly, since life changes. Some people use a rule of thumb that splits money between needs, wants and saving, but there is no single right split. This is where maths comes in: percentages, ratios, charts and spreadsheets are all used.

Behaviour matters as much as arithmetic. Advertising, friends’ choices and the urge to treat yourself can all lead to impulse buying. Pupils discuss simple habits that help, such as a waiting period before buying something non-essential, comparing prices, and keeping a small amount of “fun money” in the budget so that it feels realistic. They also consider planning for the future: short-term goals like new headphones, medium-term ones like a school trip, and long-term needs such as study, a first home or a pension. The emergency fund, a small cushion for surprises, is an important idea.

In lessons, pupils work with scenarios such as a teenager with a part-time income, a family with a fixed monthly income, or a school event with a limited budget. They are expected to justify their choices and consider trade-offs, not just find the one right answer. At Key Stage 4 this develops into topics on income and expenditure, credit and debt, savings and public money.

Words your child will hear

Budget: A plan for how money will be spent and saved over a period of time.
Income: Money coming in, such as pocket money, wages or gifts.
Expenditure: Money going out on things you buy or pay for.
Surplus: What is left when expenditure is less than income.
Deficit: The shortfall when expenditure is more than income.
Fixed and variable costs: Fixed costs stay the same each month, while variable costs change.
Savings goal: A target amount of money to save for something, with a date.

What the National Curriculum says

The programme of study for Key Stage 3 says:

Pupils should be taught about the functions and uses of money, the importance and practice of budgeting, and managing risk
Aim: pupils are equipped with the skills to think critically and debate political questions, to enable them to manage their money on a day-to-day basis, and plan for future financial needs.

Try it: saving for headphones

Sam is 14. Each month Sam gets £40 pocket money and earns £20 helping a neighbour with their dog. Sam spends £10 on a phone top-up, £12 on bus fares, £14 on snacks and food out and £10 on games and clothes. Sam wants headphones costing £84. Plan the budget.

Add up the income for the month.

Pocket money         £40
Dog helping          £20
Total income         £60

Add up the expenditure for the month.

Phone top-up         £10
Bus fares            £12
Snacks, food out     £14
Games and clothes    £10
Total spending       £46

Find the surplus: income minus expenditure. This is the amount that can go towards the goal.
```
£60 − £46 = £14 surplus
```
Work out how long the goal takes: £84 divided by £14 a month is 6 months. Sam can see whether that is acceptable.
```
£84 ÷ £14 = 6 months
```
Test a change. If Sam cuts snacks and food out from £14 to £10, spending falls to £42, so the surplus rises to £18 a month. £84 ÷ £18 is 4.67, so Sam would reach the goal in 5 months, with £6 to spare after saving £90.
```
£60 − £42 = £18
£18 × 5 = £90 (over £84)
```

Sam’s surplus is £14 a month, so the headphones take 6 months. Cutting £4 from snacks makes the surplus £18 and cuts the time to 5 months. Whether that trade-off is worth it is Sam’s choice.

Common mistakes and how to help

“Budgeting is only for people who do not have enough money”

Budgets are often mentioned in news stories about hardship, so they seem like a sign of trouble.

What helps: Point out that families, companies and governments all budget. Having more money still means choosing, and planning helps people reach goals sooner.

“A budget means no spending on fun”

Budgets are pictured as lists of things you can’t have, which feels restrictive.

What helps: Build in a set amount for treats. A realistic plan with room for enjoyment is much easier to stick to than a strict one that is abandoned.

“Small purchases do not matter”

A single drink or app purchase is cheap, so each seems harmless.

What helps: Add them up: £2.50 spent three times a week is £7.50 a week, or £30 over four weeks. Ask your child to track one week and look at the total.

“Once you have made a budget, that is it”

Children often make a plan once and expect it to stay right, but income and costs change.

What helps: Treat the budget as a draft. Check it after a month, see what was forgotten, such as a birthday or school trip, and adjust the plan.

How to help at home

Give a regular allowance, then step back. A fixed amount each week or month gives your child something to plan with. Let them make small mistakes and run short sometimes, because that is how the lesson sinks in.
Track a month of spending. Use a notebook, a spreadsheet or a bank statement. At the end, sort the spending into needs, wants and savings and ask what surprised them.
Set one visible savings goal. Pick something they really want, work out the cost and a date, and calculate how much to save each week. Seeing progress is motivating.
Try a waiting rule. Agree a pause of a day or two before any non-essential purchase over a set amount. Many wants fade, and the ones that remain are more likely to be worth it.
Plan a day out on a fixed budget. Give your child a total, such as £40 for a family trip, and let them plan travel, food and activities. Talk through the trade-offs they make.
