Answer:
interest
Step-by-step explanation:
An "interest" accrues if you don't pay the balance or the full amount after a month. For example, if you borrowed $1,000, which has a monthly interest of 5% or $50, you're expected to pay the interest if you cannot return the money in a month's time. It means you have to pay a total of $1,050. This is very common for credit cards. Thus, it is very important to pay your balance to prevent the interests from accumulating.
