You may add any percentage value to any number with the help of this adding percentage calculator.

There are instances in our daily lives when we need to add a percentage to a number. This scenario occurs while offering a tip to a waiter, calculating the entire value of a goods after tax, and so on.

To tackle these challenges, we created this adding percentage calculator. After adding the desired percentage to a given number, you can simply find the final result.

• This online calculator is extremely user-friendly.
• In the first field, type the desired number to which the percentage value will be added.
• Enter the percentage value you want to add in the second field.
• Based on the entered inputs, the calculator will display the final value.

You can use the following formula to compute the final value after adding the percentage to a number.

How to Add a Percentage to an Amount

Adding a percentage to a desired number or sum is not as common as adding two integers. Though the principle of addition is the same, the processes to doing it are not. Adding a percentage to an amount is not as tough as you would believe. We have solved several problems that will let you carry out this operation as easily as possible.

Example :

1. John and Sam aim to launch their new venture. John intends to invest \$1,000 in this new firm, and Sam intends to invest 25% of John’s investment. What will the total cost of the investment be?

Solution :

Investment of John (initial value) = 1,000\$
Investment of Sam (% of initial value) = 25%
Total Investment (final value) = ?

If you put the given values directly in the calculator you will get the total investment cost as 1,250\$. But as promised, we will simplify all the steps in calculating the final amount.

You can use the above adding percentage formula to find the final value of the investment.

Final Value = Initial Value + [(Initial Value/100)* % value]
Final Value = 1000 + [(1000/100)*25]
Final Value = 1000 + 250
Final Value = 1250\$

Total cost of investment is 1250\$.

Example :

2. Jessica and her family dined at a restaurant. The restaurant’s bill was \$55, and she wanted to leave a 10% tip for the waiter who served them the great cuisine. What will the tip amount be, as well as the total amount when the tip is added?

Solution :

Restaurant bill = 55\$
Tip percentage = 10%
Tip amount = ?
Total amount of bill after adding tip = ?

Tip amount = (Initial Value/100)* % value
Tip amount = (55/100)*10
Tip amount = 5.5\$

Total Bill Amount = Initial Value + [(Initial Value/100)* % value]
Total Bill Amount = 55 + [(55/100)*10]
Total Bill Amount = 55 + 5.5
Total Bill Amount = 60.5\$

Jessica handed the waiter a 5.5 dollar tip, bringing her total restaurant bill to 60.5\$.

3. How to add 15 percent to a number.

Solution :

In the previous solved problems, we knew the initial and percentage value. But in this problem, we only have a percentage value. So we will have to assume the initial value.

Let us assume initial value = 99
% value = 15%

Using the formula,

Final Value = Initial Value + [(Initial Value/100)* % value]
Final Value = 99 + [(99/100)* 15]
Final Value = 99 + 14.85
Final Value = 113.85

Adding 15% to 99 we get 113.85

Example :

4. How to add 20 percent to a number.

Solution :

We must assume the initial amount, just as we did in problem #3, because only the percentage value is specified in the problem.

Let us assume initial value = 249
% value = 20%

Using the formula,

Final Value = Initial Value + [(Initial Value/100)* % value]
Final Value = 249 + [(249/100)* 20]
Final Value = 249 + 49.8
Final Value = 298.8

Adding 20% to 249 we get 298.8
