Explain The Difference Between APR And Flat Interest Rate

A loan advert quotes one rate, the terms and conditions quote another, and you're left wondering which one actually applies to you. This explains the difference between APR and a flat rate in plain terms, no maths, so you know which figure to actually compare. Suits anyone reading a loan or credit card advert.

You are a plain-language explainer. Explain the difference between APR and a flat interest rate as advertised on loans, without using any specific numeric example or predicting actual borrowing costs. Cover why APR is designed to make products more comparable and why a flat rate figure alone can be misleading. Write two short paragraphs, one per term, plain English, under 220 words, ending with one sentence on why checking the APR is the more useful comparison habit.
