X% APR Typical variable
You'll frequently see this expression in promotions for loans. It means the lender is not being totally specific about the interest rate you will be charged as their rates vary, usually in response to your personal credit rating and the amount of money you want to borrow
Therefore X% APR Typical variable is used to give you a general idea of what interest rate you can expect to pay. The addition of the word 'Typical' means that at least 66% of their approved applications are offered that rate or cheaper.
For example, many of the Sofa shops offer '0% typical APR'. The law therefore states that at least 66% of applicants will get this rate. However, for people with a suspect credit rating they could well be charged 10%, 20% or even more.
