### Business Math 1 - Session 1: Interest calculations[edit]

- Interest calcualations
- Simple interest calculation
**Interest = Principal * Interest rate * Time ( I = P * R * T )**( w:fi:Korko = Pääoma * Korkoprosentti ) **w:Compound interest**arises when interest is added to the principal, so that, from that moment on, the interest that has been added also earns interest. This addition of interest to the principal is called*compounding*.

**The time value of money**is the value of money figuring in a given amount of interest earned or inflation accrued over a given amount of time. ( Wikipedia )
