Interest and charges explained

Interest

Interest is the amount added on top of the amount you borrow. Think of it as the ‘cost’ to borrow money.

For example:


  • You borrow £100 with 10% interest
  • This adds an extra £10 in interest
  • You end up paying £110 in total

Charges

Charges are extra fees (not interest) added on top of the amount you borrow.

This includes:


  • Maintenance fees
  • Transaction fees
  • Late fees

Work out what you have to pay

Make sure you can afford what you borrow.

High interest rates make it harder to keep up with repayments.

Fixed interest rates

Fixed interest rates stay the same.

This can be for some or all of the borrowing term.

Let’s say you want to borrow £500 over 3 years with a 12% interest rate.


  • Take the amount you are borrowing and times it by 1.X
  • X = the percentage rate
  • This gives you the total you are borrowing with interest
  • £500 x 1.12 = £560

Compound interest rates

Compound interest builds year on year.

This means you pay back more than on a fixed interest rate.

Let’s say you want to borrow £500 over 3 years with a 12% interest rate.


  • Take the amount you are borrowing
  • Times it by 1.X
  • X = The percentage rate
  • This gives you the amount you are borrowing plus one year of interest
  • £500 x 1.12 = £560

Do this for each year you are borrowing.


  • Take the total from the last calculation
  • Times it by 1.X
  • X = The percentage rate

This example for 3 years looks like this:


  • Year 1: £500 x 1.12 = £560
  • Year 2: £560 x 1.12 = £627.20
  • Year 3: £627.20 x 1.12 = £702.46

Credit jargon explained

123

0% credit card

A credit card that has a 0% interest rate for a set period of time.

Standard interest rates apply if you have a balance left to pay when the offer ends.

A

Annual Equivalent Rate (AER)

Banks use AER for savings and investment accounts. AER is shown as a percentage.

The percentage shows you what you could earn in interest on top of your savings.

They usually work using compound interest, meaning you can earn interest on top of interest you have already earned.

 

Annual percentage rate (APR)

APR shows you how much it costs to borrow money over a year, including interest and fees.

The lower the APR, the less it costs to borrow.

 

Arrears

Arrears are debts on a debt.

You fall into arrears when you fall behind on payments.

B

Balance transfer

This is when you move a balance from one card to another.

People usually do this:


  • With a different provider
  • To get a lower interest rate

Sometimes there are balance transfer fees.
