Simple and compound interest account

Calculation of interest rates is divided in two ways:


As the very word says is the obvious difference between the proportional and the compound method.

We will try to explain why people often make the same mistake because what is simple does not necessarily mean that it is cheaper. Much of the population thinks that the compound method is always more expensive than the proportional method, because it is the interest on the interest, in several cases it does not have to be the rule.

PROPORTIONAL METHOD in accounting for interest rates obtained by different loan amounts, depending on whether the interest is calculated at the end of the repayment period or is calculated over several times during the repayment period.

If the interest is calculated at the end of the repayment period which is the better way, to be paid less.
If the interest is calculated several times during the loan repayment results in a greater amount of interest.

CONFORM METHOD in accounting for the interest rate obtained for the same amount regardless of whether the interest is calculated once or more times during the loan repayment.
