## Find the percentage increase from one number to another

Lots of things go up in number from what you earn, to prices and even scores in a game. This calculation allows you to measure how much the increase is using percentages.

As an example we will calculate what the percent increase from 40 to 70 is.

### Step 1 - Subtract

Subtract the original number from the new number (70 - 40 = 30)

This gives us the decrease amount (30)

### Step 2 - Divide

Divide the decrease amount by the new number (30 / 40 = 0.75)

This gives us the decimal number (0.75)

### Step 3- Multiply

Multiply the decimal number by 100 (0.75 * 100 = 75%)

### Result

The answer for our example is 75%.

## Find the percentage decrease from one number to another

If something drops in number such as the amount of goods you have left, this calculation allows you to measure using percentages how much the decrease is.

As an example we will calculate what the percent decrease from 60 to 40 is.

### Step 1 - Subtract

Subtract the new number from the original number (60 - 40 = 20)

This gives us the decrease amount (30)

### Step 2 - Divide

Divide the decrease amount by the new number (20 / 40 = 0.5)

This gives us the decimal number (0.5)

### Step 3 - Multiply

Multiply the decimal number by 100 (0.5 * 100 = 50%)

### Result

The answer for our example is 50%.
