APR

APR stands for Annual Percentage Rate. In the context of computer science and finance, APR is a measure used to describe the annualized cost of borrowing or the annual return on an investment, expressed as a percentage. It includes not only the interest rate charged on a loan or earned on an investment but also any associated fees or costs, allowing for a more comprehensive comparison between different financial products.

APR is commonly used in loans (such as mortgages, car loans, and credit cards) to indicate the true cost of borrowing over a year, enabling consumers to make informed financial decisions. In programming and financial applications, calculating and displaying APR accurately is crucial for compliance and transparency. It is an important parameter in financial algorithms and models that require clear and standardized comparisons of financial products.
