Add Percentage to a Number

The add percentage calculator finds a new number increased by a given percent. It uses the following formula:

$\frac{100\%+\text{percent}}{100\%}·\text{number}$

According to the formula, to add a percentage to a number you multiply the number by a coefficient greater than one.

For example
A coefficient of 1.01 means an increase of 1%.
A coefficient of 1.5 means an increase of 50%.

The calculator adds a percentage to a number and shows every step of the calculation.

Example
The number 25 increased by 10%. Find the new number.
$\frac{100\%+10\%}{100\%}·25=1.1·25=27.5$
Answer: 25 + 10% = 27.5

Example
A bus ticket costs $2.00. Next month the fare goes up by 7%. Find the new ticket price.
$\frac{100\%+7\%}{100\%}·2=1.07·2=2.14$
Answer: $2.14
