What is Compound Interest?

  • It is the concept of adding accumulated interest back to the principal (initial amount)
  • When you save money in a bank, you receive interest
  • The interest is calculated on your balance and then deposited to your balance
  • The next years interest is calculated taking last years interest into account hence the interest is compounding

Compound Interest can be worked out for both appreciation (rising) and depreciation (falling) quantities.

The Study Guides explain two methods to calculate Compound Interest:

  • Formula method
  • Year on year method
