How to find the percentage of a value

When it comes to calculating the percentage of a given amount, it's simple to follow a basic method: just divide the percentage value by 100 and then multiply it by the amount you have.

On the other hand, if you prefer a more simplified approach, there's a mathematical formula that can give you the desired result directly. Check out the formula below to easily calculate your percentage:

R = p/100 x V

Check the meaning of each variable in the formula to calculate the percentage:

R = the result of your account. 

P = percentage.

V = value to be calculated.

Now let's look at a practical example: If you wanted to know how much 5% is of the value of R$ 200.00, the formula would be like this:

R= p/100 xv

R = 5/100 x 200

R = 0.05 x 200

R= 10

In the example, the result of the account, 5% of R$ 200 is equivalent to R$ 10.00.

To perform the calculation, you have two options: apply this formula or use our online percentage calculator to get the answer more quickly.
