To calculate the percent of the number, need the number to be multiplied by the percentage then divide by 100. For example, if the employee's salary amounted to 30,000 rubles, income tax (13%) of this amount will be: 30000 * 13 / 100 = 3900 rubles.

2

To calculate the percentage of a conventional calculator, perform the following sequence of actions. Enter on the keyboard number % (button%" while pushing is not necessary). Click on any of the signs of arithmetic operations ("+", "-", "x","/", in this case this button is used as the delimiter when you enter numbers). Now type on the calculator the number from which you want to calculate the interest. Click on the "%". On the display of the calculator appears the desired result.

3

Calculating percentages of numbers using a computer. To do this, run the standard Windows calculator. To do this, click start - > Run -> type "calc" -> OK. If the calculator is loaded into "Engineering" form, install it in "Normal" mode ("View" -> "Normal"). Then calculate the percentage of the number is the same as described in the previous paragraph instructions.

4

To calculate the percent of the number in MS Excel, type the following sequence of characters: "=" "number" "*" "percentage" "Enter". So, for example, to calculate 13% of 10000, enter in the desired cell the following formula: =10000*13% and press "Enter". If you did everything correctly, then in the cell instead of the formula will appear as 1,300.

# Advice 2: How to calculate a percentage of the amount

The percentage in Latin ("pro centum" means one-hundredth. So if you want to find a certain percentage of a certain amount of money, it means that it is necessary to determine how many hundredths of the sum contains the specified percentage. If in mind to not count it turns out, the easiest way to calculate a percentage using a calculator.

Instruction

1

Use to calculate the percentage of a given amount, for example, the standard calculator Windows. Link to his start-up can be found in the main menu system - open it by pressing WIN key or click the mouse on "start" button. You need to go to "All programs" to reveal in this subsection "Standard" and click the string "Calculator." However, hackers are not a fan of "mouse computing" and if you also want to feel like a little hacker, then press the key combination WIN + R, type calc and press Enter. Both run the same Windows calculator.

2

Keep the number ofyour equivalent of the available amount of money. This operation can also be performed with the mouse, and only keyboard - right buttons of the calculator interface duplicate the same keys on the keyboard.

3

Find one hundredth part of the number entered. To do this, use the key with a slash (slash) on the keyboard interface on the screen, and then enter the number 100.

4

Multiply a hundredth of the amount to a known amount of interest. To do this, press on the keyboard or click the mouse on the screen the button with the asterisk, and then type the percentage.

5

Complete the calculation of the percentage of the amount by tapping on the keyboard or clicking on-screen buttons with the sign of equality. The calculator will show you the numeric expression specified percentage of the amount entered.

6

Having access to the Internet for solution of this problem you can do without a calculator. In the network there are many analogues that allow us to make the required calculations directly in the browser window. If there is no time to search for and develop such online services, then enter the desired mathematical expression directly in the query box of Google search engine and immediately get a result. For example, to calculate 13% from the sum of 25 thousand 512 rubles 14 kopecks, enter the following query: "25521,14 / 100 * 13".

Note

How to calculate percentages. In everyday life often need to be able to determine what percentage of a particular number from the integer part. It is a mathematical action that are in high school, could come in handy in the case of the calculation of various loan repayments, calculate ratios for any purchases, and only on the job regularly has to use comparative characteristics, expressed in percent.

How to calculate percentages? 4 APR 2012. Category: Training. No comments. Surely you are not just faced with such a thing as "percentage". And some even required it to count. The first way is to calculate in mind: the Number from which you want to find the percentage you need to divide by one hundred and then multiply by the percentage. Or just multiply the number by the percentage expressed in hundredths (percent divided by one hundred). For example, we need to find 28% of the 924.

# Advice 3: How do you think the interest on the Deposit

Opening an account is a popular solution in order to ensure the safety of savings and multiply them. The yield on the Deposit depends on the set of interest on it, and the method of their accrual. It is therefore important to know how to count.

To calculate the interest on the Deposit will clarify how is the calculation. So, they can be charged at the end of the Deposit period, quarterly or monthly. There are also two types of interest - simple and complex (with capitalization).

2

When calculating simple interest they with a certain periodicity defined in the contract, is transferred to a separate account and do not join the Deposit amount. To calculate them quite easily. For this initial Deposit amount and multiply by the annual rate and the number of days on which you opened the contribution. Then the resulting amount will be divided by 100 and the number of days in the year (365 or 366). For example, the contribution by the sum of 100 thousand rubles opened for 90 days with a rate of 9.8% per year. The yield on the Deposit will be 2416,4 R. (100*9,8*90/365/100). If the contribution opens for the year you just need the amount of the contribution multiplied by the percentage.

3

When contribution with the capitalization of accrued interest attached to the Deposit amount within the time prescribed in the contract. This files most often - monthly or quarterly. As a rule, the investor has a choice to make interest, or to withdraw the yield. But in case of capitalization increases the amount of the contribution, respectively, grow and accrue interest. To calculate the amount of the Deposit with interest should the initial amount of the investment multiplied by the annual rate and number of days on which the Bank carries out capitalization and divided by the number of days in a year and 100. For example, investing 100 thousand rubles with the rate of 9.8% with monthly interest capitalization amount of interest for January will be 832,3 R. (100*9,8*31/365). It turns out that in February, interest will accrue on the Deposit amount 100 R. 832.3 the Further calculations are carried out similarly. If you want to calculate the amount of interest on Deposit for a specified period should the initial Deposit amount multiplied by ((1 + annual interest rate*number of days/number of days in a year/100) in-degree (number of interest periods — 1).

4

If the formula for calculating the return seem unnecessarily complicated, you can always contact a representative of banks to provide you with detailed information. Also on the websites of most banks have a calculator that allows you to automatically calculate the accrued interest based on the specified parameters.

Note

If the percentage of the contribution by more than 5% higher than the refinancing rate of the Central Bank of the Russian Federation, then the profits investors are taxed 35%.

Useful advice

At the same interest rate of deposits with capitalization, provide greater profitability. It should take into account when choosing contribution.
