Why is it important to estimate the interest rate of a loan?

The interest rate is what will allow you to determine what is the value attached to a financial loan , which you will have to pay. It is, basically, the price that a lender establishes for granting you a certain amount of money.

For that reason, it is expressed as a percentage , since it measures the consideration of money within the financial category. Just calculating the interest rate serves many purposes for you . For example:

  • Estimate how much you will pay to apply for a loan with a certain bank.
  • Corroborate how much you are paying at the moment (if you have contracted a loan).
  • Compare several financial loans to choose the most attractive one.

Through an interest rate calculator you will get the price you will have to pay for getting a certain amount of money. This, precisely, is what is known as the interest rate.

And, the percentage will be added to the initial capital that the financial institution will grant you, or has already done so.

Practical example on how to use the interest calculator

To make it easier for you to use this tool, let's put a practical example. For this, we have the following random data :

  • Total amount expressed in EUR : $ 2,000.
  • Monthly payment expressed in EUR : $ 323.
  • Term expressed in months : 12 months.

Using the financial calculator, the result shows that the price of this loan is 12.01% .

Another practical case that we could consider is a loan with a repayment period of more than one year. For example, an installment loan . For this, we have the following information:

  • Total amount expressed in EUR : $ 6,000.
  • Monthly payment expressed in EUR : $ 415.
  • Term expressed in months : 36 months.

In this case, the financial calculator shows that the value of your credit is 6.09% . That is, the additional that would be added to your credit.

Calculate simple interest with mathematical formula

There are other ways to calculate simple interest rate. One of them would be by means of a mathematical formula, that is, in a traditional way . For this, you would have to take into account what would be the formula to use, and how to use it. Let's take a practical example:

The simple interest formula is: I = C * i * T

Where the initials have the following meaning:

  • I: Interest
  • C: Capital
  • i: Interest rate
  • T: Time

For this example, let's take random data :

  • C: $ 15,000.
  • i: 7%
  • T: 6 months.

Substituting the values:

I = 15,000 * 0.07 * 6 = $ 6,300

So, you would have to pay a total of $ 6,300 in interest . Adding it to the initial capital, at the end of the loan you would have to return a total amount of $ 21,300 to the financial institution.

Is it the same as a loan simulator?

No! A loan simulator is a much more comprehensive tool, as it allows you to estimate:

  • Actual cost of a loan.
  • Dues.
  • Commissions derived from the borrowed capital.

Basically, it breaks down a loan in detail . So, it is a good support when comparing several financial credits, as it allows you to make a better decision.

In contrast, an interest rate calculator only focuses on the interest rate that will be applied to the total principal granted by a lender. For this, it is based on specific data that you will have to provide. In short, it tells you the percentage to add to the amount of your credit.

Similarly, both are valuable tools . Only, each one fulfills its function.

Calculate simple interest rate allows you to know the price of your loan expressed in a percentage , which would allow you to estimate the total interest expressed in US dollars.
