How to figure out percentage increase?

When a quantity grows, then we can calculate percent increase:

Percentage Increase = (New Amount - Original Amount) / Initial Amount * 100

When an amount shrinks (becomes smaller), then we can calculate percent decline:

Percentage decrease = (original amount - new amount) / Initial amount * 100

Both formulas have the following pattern:

Per cent increase / decrease = Change in amount / Original amount * 100

Example 1:

Question: A price rose from USD 5, - to USD 7, -. How many percent increase is this?

Solution: What was the original price? Answer: USD 5, - (This will be the denominator)

Per cent increase = (7-5) / 5 * 100 = 40%

Example 2:

Question: An amount decreased from 90 to 75. How many percent reduction is this?

Solution: What is the original amount? Answer: 90 (This will be the denominator)

Percentage decrease = (90-75) / 90 * 100 = 16.67%
