🧮 What is Compound Interest?
Compound interest is the interest you earn on both the original amount (principal) and the accumulated interest from previous periods. It’s often referred to as “interest on interest,” and it’s one of the most powerful concepts in finance.
Formula:
A = P × (1 + r/n)^(nt)
Where:
- P = principal amount
- r = annual interest rate (in decimal)
- n = number of times interest is compounded per year
- t = number of years
- A = final amount (principal + interest)
This is different from simple interest where interest is calculated only on the principal.
