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.

**Adding Percentage Calculator Use**

- 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.

**Adding Percentage Formula**

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 = ?

Using the percentage addition formula,

**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**
