Understanding Compound Interest
Compound interest is a powerful financial concept that allows your investments to grow exponentially over time. Unlike simple interest, which is calculated only on the principal amount, compound interest is calculated on the initial principal and also on the accumulated interest from previous periods. This means that the longer you invest, the more your money can grow.
What is Compound Interest?
Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It is often referred to as "interest on interest," and it can significantly increase the amount of money you earn over time.
The Formula for Compound Interest
The formula to calculate compound interest is:
A = P (1 + r/n)^(nt)
- A: the future value of the investment/loan, including interest
- P: the principal investment amount (the initial deposit or loan amount)
- r: the annual interest rate (decimal)
- n: the number of times that interest is compounded per unit t
- t: the time the money is invested or borrowed for, in years
Benefits of Compound Interest
- Exponential Growth: The most significant advantage of compound interest is that it allows your money to grow at an accelerating rate.
- Long-Term Investment: The longer you leave your money invested, the more you can benefit from compound interest.
