Investopedia explains 'Personal Interest'
Personal interest includes interest on car loans, credit cards, loans for appliances and furniture and interest on loans made by one person to another.
Many consumers elect to take out lines of credit on the equity in their homes so that they can pay off their personal-loan balances and deduct the interest on their lines of credit instead.
