You've just been offered a pre approved credit card. Should you take it?

Taking up a pre approved credit card offer can improve your credit score and earn you better rewards on the things you buy. If you are among the , however, think twice about these offers if you're already struggling to pay off debt, experts advise. One of the main advantages of taking up a credit card offer — one that doesn’t require an application or result in a “hard inquiry” into your credit — is that it can improve your credit utilization ratio, says Cindy Marques, a certified financial planner and director at Open Access Ltd.

Expressed as a percentage, your credit utilization ratio is the amount of credit you’re using divided by the total amount of credit available to you. Generally, a credit utilization score below 30 per cent can . Marques explains that taking up a credit card offer will increase your credit limit and reduce your utilization ratio.

She says taking up one of these offers could also improve your credit mix. “If you only have a line of credit or a student loan, adding a new type of debt product to the mix will improve your score by being able to manage different types of debt products.” Some credit card welcome offers come with promotions on a balance transfer, which involves shifting your balance from one credit card to another.

“You want to be mindful that this isn’t opening up Pandora’s box,” says Marques. “It really does depend on the consumer’s behaviour and their ability to resist the temptation to make matters worse.”.
