How a Credit Card Works
Having a credit card gives you access to money from the bank that can be used for all purchases. You can, in theory, spend freely as long as you stick to the limits set in your agreement and more importantly, pay everything back when you need to.
Failing to repay the credit in the allotted time means that you will pay interest fees - which are specified when you sign up for a card. It is not an instant repayment, so you do not need to rush to pay it back. Instead, you normally have 30 or 60 days to make the repayment.
It is also worth noting that you can repay what you owe over time. For example, if you make a small payment before the 30 or 60 days, it will be interest-free. But if you take longer than the agreed period, you will be subject to interest fees on the rest of what you owe.
There are positives to having a credit card, too. Such as the fact that some stores and websites offer discounts when using a credit card, whilst you can also get cashback and extra protection through insurance provided by having the credit card.
Each option provides different benefits, and there can be more than cashback and insurance!
Finally, it needs to be stated that having a credit card is a big responsibility. Whilst it can be beneficial to have one, if you struggle with finances, it can quickly become a burden and be more stress-inducing. Having a credit card is not for everyone, that is important to note.
