### Percent increase from 80 to 90 is 12.5 percent! Explanation: What does 12.5 percent or 12.5% mean?

Percent (%) is an abbreviation for the Latin “per centum”, which means per hundred or for every hundred. So, 12.5% means 12.5 out of every 100. For example, if you increase 80 by 12.5% then it will become 90.

### Methods to calculate "What is the percent increase from 80 to 90" with step by step explanation:

#### Method: Use the Percent Increase Calculator formula (New Number - Old Number/Old Number)*100 to calculate "What is the percent increase from 80 to 90".

- From the New Number deduct Old Number i.e. 90-80 = 10
- Divide above number by Old Number i.e. 10/80 = 0.125
- Multiply the result by 100 i.e. 0.125*100 = 12.5%

#### Answer: Percent increase from 80 to 90 is 12.5 percent

### Percentage examples

Percentages express a proportionate part of a total. When a total is not given then it is assumed to be 100. E.g. 80% (read as 80 percent) can also be expressed as 80/100 or 80:100.Example: If 80% (80 percent) of your savings are invested in stocks, then 80 out of every 100 dollars are invested in stocks. If your savings are $10,000, then a total of 80*100 (i.e. $8000) are invested in stocks.

### Differences between percentages and percentage points

Let s take an imaginary example: In 2020, 90 percent of the population could use Inernet, and in 1990 only 10 percent could use the Internet. One can thus say that from 1990 to 2020, the Inernet usage increased by 80 percentage points although Internet usage grew at much higher pace (it increased by 900 percent from 10 to 90). In short percentages indicate ratios, not differences.Percentage-point differences are one way to express a probability of something happening. Consider a drug that cures a given disease in 80 percent of all cases, while without the drug, the disease heals on its own in only 65 percent of cases. The drug reduces absolute risk by 15 percentage points.
