The main difference is on how to calculate interet.
For simple interest, the interest is added to the principle at the end of the time to get the final amount.
For compound interest, the interest collected at each interest receiving period is added to the principle to become the new principle for next interest period.
Since the interests in compound interest are added to the principle become part of new principle, the interest obtained will always be greater than the interest received under the same interest rate and time period than that for the simple interest.
