With the objective of helping people to perform calculations considered complex, but that, at some point in life, are necessary, the Central Bank of Brazil created the Citizen Calculator application. Through this tool, the user is able to simulate financing, make predictions of income from applications and other operations, such as correcting values ​​based on inflation and savings indices, for example.

In addition to the app (for Android, via the Play Store, and iOS, via the App Store), there is also a web version, both available for free. The Central Bank warns that the Citizen’s Calculator is not intended to measure the calculations performed by financial institutions in contracting their credit operations, since other costs not considered in the simulation may be involved, such as insurance and other operational and tax charges. not considered by the tool.

Citizen Calculator features and step by step

Financing

The “Financing” tool brings together four fields: financed amount, number of months, monthly interest rate and installment amount. The app can calculate any of these variables. For this, the user must fill in the other three fields.

Step 1

Fill in the fields “Funded Amount”, “Number of Months” and “Monthly Interest Rate”:

step 2

To find out the value, just tap on the empty “Valor da Prestação” field, and the application will give you the information you are looking for:

Note that, just below the value informed, there is a detailed explanation about the simulated operation, including the total amount of interest paid at the end of the determined period.

step 3

To do another calculation, just click the “Clear” button:

step 4

You have the option to share the result of your calculation with any of your contacts via Whatsapp, Facebook Messenger or another app via the “Share” button:

step 5

You also have the option to change any of the variables provided. To do this, just click on the field you want to modify the value or move the hand icon on the side. In this example, let’s assume you want to increase from 60 to 80 months:

Note that, thus, the value of the installments decreases, and the total amount of interest increases, as described below the four fields.

The dynamics are the same for any other variant of the calculus. If you want to calculate how many months it will take to pay off a certain amount by paying a certain amount (in this case, for example, R$1 thousand), just fill in the “Amount of installment” field, the interest rate and the total amount, and the system will inform you How many months will your debt be paid? That is, any of the four variants can be discovered by informing the other three.

2. Application

If you want to know how much you will have after a certain time making monthly deposits, on the application’s home screen, click on “Application”. As in the “Funding” operation, the application calculator can inform the value of any of the four variables: regular deposit amount, number of months, monthly interest rate and amount obtained at the end. You can fill in the three fields you know and tap on the fourth one to see the result.

Step 1

To find out how much you need to deposit per month to have R$10,000 after three years (36 months), for example, enter these amounts and add the interest rate. The amount will appear once you tap “Regular deposit amount”:

step 2

To find out the amount, just tap on the empty field “Regular Deposit Amount”, and the application will give you the information you are looking for:

As with the operation taught above, you can also clear the fields and share the calculation with any of your contacts.

3. Correction of values

This option is used to update a value according to the financial index, such as, for example, savings, the CDI (Interbank Deposit Certificate), the Selic rate or the IGP-M (General Price Index – Market).

Step 1

Click on the “Correction index” field and select the option you want from the 12 available. In this tutorial, we will use the new savings as an example:

step 2

In the “Start date” field, choose the beginning of the period for updating the value and click “Ok”. Do the same with “End date”:

step 3

Then, fill in the value to be corrected and wait a few seconds. The Citizen’s Calculator will show the corrected amount on the final date, indicating the period’s correction index:

As with the two operations taught earlier, you can also clear the fields and share the calculation with any of your contacts.

4. Future Value

This calculation simulates the final value that the investor can obtain if he applies, on the current date, a certain amount of money at a certain interest rate for a certain number of months.

To perform the simulation, the user must fill in, exactly as in the previous metrics, three of the following four fields: current capital, number of months, monthly interest rate and value obtained at the end. The fourth field will be calculated by the tool.

Step 1

Suppose you have a certain amount to invest and you want to find out how much will be earned at the end of 24 months, at an interest rate of 2% per month. To do this, fill in the three initial fields:

step 2

Tap on the “Value obtained at the end” field to access this information:

Just like in the previous operations, it is possible to enter any other three fields to know the value of another of the four variants. The Clear button is also available in this option, as is the Share button.
