How it works

  • Income: take-home pay, benefits, other regular money in.
  • Fixed costs stay the same each month: rent, council tax, phone contract.
  • Variable costs change: food, energy, transport, fun.
  • Surplus = income − all costs. If negative, it is a deficit: cut variable costs first.
  • Pay yourself first: move savings on payday, before spending.
  • Look at three months of bank statements to find your real spending.

Worked example 1

Income £1,600. Rent £700, council tax £120, phone £20, food £250, energy £110, transport £90. What is left?

  1. Fixed: 700 + 120 + 20 = £840.
  2. Variable: 250 + 110 + 90 = £450.
  3. Total costs £1,290.
  4. 1,600 − 1,290 = £310.

Answer: £310 surplus

Tips

Common mistakes

  • Forgetting yearly costs such as TV licence or car MOT — divide them by 12.
  • Forgetting yearly or irregular costs, such as car insurance or birthdays. Divide them by 12 and include them monthly.
