What is money called that is borrowed and paidback with interest?

Money that is borrowed and paid back with interest is commonly referred to as a loan. When an individual or entity takes out a loan, they receive a specific amount of money from a lender, which they agree to repay over time, typically with additional interest. This interest compensates the lender for the risk and opportunity cost of lending the money. Loans can vary in terms, including duration, interest rate, and repayment conditions.
