Cash back credit cards have grown in popularity because they allow consumers to make extra cash on day-to-day purchases. However, some critics argue that credit card rewards encourage impulse buying leading to money problems and unmanageable credit card debt. High interest payments on debt can render any incentives offered completely worthless.

How to Make Extra Cash from a Cash Back Credit Card

A cash back credit card provides customers with the opportunity to typically earn up to 1 per cent of their total expenditure as a cash payment. American Express currently offers customers the chance to make 5 per cent for the first 3 months and 1.5 per cent thereafter. Credit card rewards can be much higher for financial institutions that have secured special deals with merchants.
