Interest and debt
Interest basics
▶ Introduction to interest
Simple interest is calculated as a percentage of the original amount borrowed (the principal) and remains the same over time. Compound interest, on the other hand, takes into account the accumulated interest as well, meaning that the amount owed grows at a faster rate and the total sum owed will be higher than with simple interest.
▶ Compound interest
In this video, we expand the equation to calculate simple interest for a single period, P*(1+r), to calculate interest when interest is charged for more than one period and that interest is compounded at different intervals. By doing so, we can better understand the difference between simple and compound interest.
