Understanding the Increase Percentage Formula
The formula for calculating increase percentage is straightforward:
Increase Percentage = [(New Value - Original Value) / Original Value] * 100
Let's break down each component:
- New Value: The value you are comparing to the original value.
- Original Value: The starting value.
- Increase: the different between the New Value and the Original Value.
The result is multiplied by 100 to express the increase as a percentage.
Steps to Calculate Increase Percentage
- Determine the Original Value and the New Value: Identify the two values you want to compare. For example, let's say a product's price increased from $80 to $100. The original value is $80, and the new value is $100.
- Calculate the Difference: Subtract the original value from the new value. In our example, $100 - $80 = $20. This represents the amount of the increase.
- Divide by the Original Value: Divide the difference ($20) by the original value ($80). So, $20 / $80 = 0.25.
- Multiply by 100: Multiply the result by 100 to express it as a percentage. 0.25 * 100 = 25%.
Therefore, the price of the product increased by 25%.

Real-World Examples
- Tracking Investment Growth: If your investment portfolio increased from $5,000 to $6,000, the increase percentage is [($6,000 - $5,000) / $5,000] * 100 = 20%.
- Analyzing Sales Performance: If your company's sales increased from 1000 units to 1200 units, the increase percentage is [ (1200-1000)/1000 ] * 100 = 20%.
- Calculating Salary Increase: If your salary increased from $60,000 to $66,000, the increase percentage is [($66,000 - $60,000) / $60,000] * 100 = 10%.
Understanding Percentage Increase vs. Percentage Point Increase
It's crucial to differentiate between percentage increase and percentage point increase. A percentage increase reflects the relative change in a quantity, as we've discussed above. A percentage point increase, on the other hand, refers to the absolute difference between two percentages.
For example, if an interest rate increases from 5% to 7%, that's a 2 percentage point increase. To calculate the percentage increase, you'd use the formula [ (7-5) / 5 ] * 100 = 40%. This illustrates that while the absolute change is 2 percentage points, the relative change or percentage increase is actually 40%.
Why is Understanding Increase Percentage Important?
- Financial Planning: Helps in assessing investment returns, inflation, and budget changes.
- Business Analysis: Allows tracking sales growth, cost changes, and market trends.
- Academic Performance: Useful in evaluating improvements in grades or test scores.
- Everyday Life: Helps in understanding price changes, discounts, and savings.
Tips and Considerations
- Accuracy: Double-check your values to ensure accurate calculations.
- Context: Always interpret the increase percentage within the appropriate context. A high percentage increase may not always be significant if the original value was very low.
- Negative Values: If the new value is lower than the original value, the result will be a negative percentage, indicating a decrease.
Calculating Percentage Decrease
While this article focuses on percentage increase, you can easily find the percentage decrease using a similar formula:
Decrease Percentage = [(Original Value - New Value) / Original Value] * 100
