Principal is the amount of money a company borrows when it takes a loan. This amount is recorded on a promissory note as proof of the debt owed.
In all but the rarest of situations, the borrower must pay interest, which is the lender’s fee for making money available. The interest is calculated on the principal and almost always paid monthly.
