Types of InterestTypes of Interest
• Compound InterestCompound InterestInterest paid (earned) on any previous interest
earned, as well as on the principal borrowed (lent).
Simple InterestSimple Interest
Interest paid (earned) on only the original amount, or principal borrowed (lent).

Future Value (FV)Future Value (FV)
• FV is the value at some future time of a present amount of money, or a series of payments, evaluated at a given interest rate.
• The process of going from today’s value to future values is called CompoundingCompounding
FV = PV (1 + i)ⁿFV = PV (1 + i)ⁿFV = Future ValueFV = Future ValuePV= Present ValuePV= Present Valuei= interest ratei= interest raten = No of yearsn = No of years

FV ExampleFV Example
• Assume that you deposit Rs.1,000 in an account earning 7% simple interest for 2 years. What is the accumulated interest at the end of the 2nd year?
FV = PV (1 + i)ⁿFV = PV (1 + i)ⁿ
