Convert and compare APR and APY across different compounding periods.
Compound interest is the interest earned on both the original principal and the interest accumulated over time. Unlike simple interest, compound interest grows exponentially and plays a crucial role in investments, savings, and loans.
Simple interest is calculated only on the principal amount. It is rarely used in modern finance.
Compound interest is calculated on the principal plus previously earned interest, resulting in faster growth.
Compound interest can dramatically grow investments over long periods. However, it can also significantly increase debt if loans are left unpaid.
Interest can compound annually, monthly, daily, or even continuously. The more frequently interest compounds, the higher the total return.
Where P is the principal, r is the interest rate, n is compounding frequency, and t is time in years.
