Budgets & Bank Statements

What is a budget?

  • A budget is an estimation of someone's financial incomes and outgoings

  • Budgeting helps to plan and forecast how much money you have

  • This is useful when you're aiming to save money over time

    • Knowing your monthly income and outgoings will reveal how much you can aim to save each month

    • A budget will help highlight areas that are fixed outgoings, and areas which could be cut back to help save money

  • A budget can help individuals be more objective about their finances

    • E.g. They may "feel" they are spending a sensible amount of their earnings on new clothes and shoes

    • But when a budget is created and they see the true amount and proportion of their income, they may feel differently!

Using a bank statement to budget

  • Below is a simplified version of a bank statement for a current account for one month

    • A current account is a bank account for managing day-to-day expenditures

    • A bank statement is a document from your bank showing money going in and out of an account, usually in a table

  • It includes some common codes you may see on a bank statement

    • DD - Direct Debit

      • This is an automatic payment system, often used for bills

      • It is not fixed, it changes depending on how much you owe

    • DEB - Debit card spending

    • CPT - Cash point withdrawal

    • TFR - A transfer of money between two bank accounts

    • SO - Standing Order

      • This is a recurring fixed payment

      • E.g. regularly putting money into your savings account

  • Credit means money coming in to your account

  • Debit means money leaving your account

  • Balance is the running total of money available in your account

  • By categorising the incomes and expenditures across the month, and finding the total for each, the statement can be used to create a budget

  • Income

    • Salary: £1900

    • Total in: £1900

  • Outgoings

    • Housing (rent and council tax): £850

    • Groceries and shopping: £370

    • Utilities (gas, electric, water): £160

    • Loan repayment: £120

    • Transport & fuel: £60

    • Cash withdrawals: £50

    • Internet & phone: £48

    • Entertainment & social: £24

    • Moved to savings: £200

      • This is obviously a "good outgoing"!

    • Total out: £1882

  • It is important to also consider longer term costs, or costs which don't appear each month, for example:

    • An annual car service

    • Insurance which renews yearly

    • Buying presents for Christmas or other celebrations

  • Once the budget is formed, it can be used to highlight where savings could be made

  • Some credits and debits are fixed, whilst some are variable

    • Your food shopping or spending on luxuries is considered variable

    • Whereas council tax or your rent or mortgage would be considered fixed

      • They could still change, but over a longer term

Bills

What types of bills are there?

  • Bills are regular payments for products or services, for example:

    • Utility bills (gas, electric)

    • Mobile phone

    • Internet service

    • Streaming subscriptions

    • TV license

    • Council tax

    • Insurance

  • Bills may change depending on your usage (e.g. electricity usage)

    • Or they may be fixed with a cap on usage (e.g. mobile phone data)

  • Some bills may just need to be paid once, like paying a tradesman for a job

    • You should receive an invoice detailing what needs to be paid

What is insurance?

  • Insurance protects you against losing money if something unexpected happens

    • E.g. a car accident or a house fire

  • You pay a regular fee (a premium) to an insurance company

  • If something goes wrong, the insurer pays most of the cost, though you usually pay a small amount called the excess

  • Car insurance is a legal requirement in the UK

    • It covers damage to other people’s cars, and with extra cover, your own too

  • Other common types of insurance include:

    • Home insurance

      • In case of damage to your home

    • Life insurance

      • In case of injury, illness or death

    • Health insurance

      • To help pay for private medical treatment

    • Travel insurance

      • To recover costs from cancellations or medical expenses

    • Gadget insurance

      • E.g. If your phone is damaged or stolen

  • People buy insurance when the cost of possible damage is much higher than the cost of the premium, even if the chance of it happening is small

How is a utility bill calculated?

  • Utility bills, e.g. for gas, electric, or water, comprise of several parts:

    • A standing charge

      • This is fixed for the period, no matter how much you use

    • A cost dependent on number of units used

      • Your electricity, gas, or water meter will be used to measure this

      • Electricity is measured in kWh (kilowatt-hours)

      • Gas and water usage is measured in m3 (cubic metres)

    • VAT (value added tax)

      • This is usually 20%, but for utility bills it is 5%

  • Utilities have a tariff which sets out the costs for standing charges and costs per unit

Worked Example

Cerys is checking her electricity bill she has received covering the last 3 months.

Her meter at the start of June read 10 468 kWh and at the end of August it read 11 008 kWh.

Her electricity tariff contains the following information:

  • The standing charge is 48p per day

  • Electricity costs 31p per kWh

  • VAT at 5% is payable on the total of the standing charge and the cost of the electricity used

Calculate the total of Cerys' electricity bill for the 3 month period of June to August.

Answer:

Calculate the amount of electricity used (in kWh) by finding the difference between the meter readings

11 008 - 10 468 = 540 kWh

Multiply this by the cost per kWh (31p per kWh)

Do this in pounds, rather than pence (31p = £0.31)

540 × 0.31 = £167.40

Add on the standing charge, which is charged at 48p (£0.48) per day

You need to first calculate the total number of days in June, July and August, then multiply by £0.48

30 + 31 + 31 = 92 days

92 ×0.48 = £44.16

Add the standing charge and the price for the electricity usage together

167.40 + 44.16 = £211.56

Add on the 5% VAT, using a multiplier of 1.05

211.56 × 1.05 = £222.138

Round to the nearest penny

£222.14
