Bills and buffers

Can you survive three months of bills, wages, budget choices and financial surprises?

Bills & Buffers is a financial literacy game where students manage money across three simulated months. They calculate income, build a budget, handle unexpected events, check bank statements and try to finish with enough balance, security and sanity intact.

The aim is not simply to spend the least. Students need to make sensible trade-offs between money, lifestyle, security and stress.

How the game works

Each month has several stages:

1. Payslip — calculate gross pay, deductions and take-home pay.
2. Budget desk — choose housing, bills, food, transport, subscriptions and savings.
3. Life events — survive random financial problems and opportunities.
4. Bank check — calculate the final balance from a statement.
5. Month report — screenshot the result before moving on.

Students play through three months, with the difficulty increasing as the game progresses. At the end, they receive a final report showing their score, ending, monthly results and topic accuracy.

Maths skills included

The game is designed around Year 8 finance and percentage topics, including:

• wages and overtime;
• income tax and deductions;
• budgeting and expenditure;
• bank statements, credits, debits and balances;
• bills and receipts;
• utility bills and meter readings;
• VAT;
• percentage increase and decrease;
• reverse percentages;
• offers and discounts;
• simple and compound interest;
• depreciation and repeated percentage change;
• decimal calculations with money.

Students are expected to pay attention to pounds and pence. Money answers usually need to be given to two decimal places.

Events students may face

During the game, students may need to deal with events such as:

• a utility bill based on meter readings;
• a bill quoted before VAT;
• a bank statement error;
• an unexpected repair;
• a supermarket voucher;
• a subscription price rise;
• overtime opportunities;
• depreciation on an item;
• reverse-percentage sale-price problems.

These events are not just decorative. The maths affects the budget.

Classroom use

This activity works well as an end-of-unit or end-of-term task for Year 8 students. It can be completed individually, in pairs or in small groups.

Suggested use:

• allow around 45–60 minutes;
• ask students to screenshot each month report or the final report;
• encourage students to compare strategies, not just scores;
• discuss whether their choices were financially sensible, risky or realistic.

The game also includes collectible endings, so students can replay it and try different approaches.

Teacher note

Bills & Buffers is not intended to be a perfect model of adult finance. It is a classroom simulation designed to make financial maths feel meaningful. Students see how calculations involving percentages, decimals and money connect to real-world decisions: rent, bills, savings, subscriptions, repairs and income.
