A debit card is linked to a checking account at a bank that you have to open. When you use your debit card, you are spending your own money that you have placed in this account. A credit card is given to you by a company if you apply for it and are approved, and it has a monetary limit (ex: $15,000). You can spend any amount of money on this card as long as all of your purchases total more than the limit. You then get sent a credit card bill, which means that you have to pay back all of the money that you spent with interest. A budget is an allotted amount of money that you are allowed to spend within a certain time span. A payday loan is a small loan from a bank.
