Time Value of Money • Prefer payment now vs. in future due to interest factor • Applicable to both personal and business decisions 18
Simple Interest I = P x R x T Dollar amount of interest per year Time in years Principal amount Interest rate as a percentage
Example of Simple Interest Given following data: principal amount = $ 3,000 annual interest rate = 10% term of note = 2 years Calculate interest on the note. 20
Example of Simple Interest Given following data: principal amount = $ 3,000 annual interest rate = 10% term of note = 2 years Calculate interest on the note. P x R x T $ 3,000 x .10 x 2 = $ 600 21
Compound Interest Interest is calculated on principal plus previously accumulated interest Compounding can occur annually, semi-annually, quarterly, etc. 22
Example of Compound Interest Given following data: principal amount = $ 3,000 annual interest rate = 10% term of note = 2 years semiannual compounding of interest Calculate interest on note.
