What is Percentage Increase?
Percentage increase represents how much a value has grown compared to its original value, expressed as a percentage. It helps you quantify growth in various contexts — population, sales, investments, or even your body weight!
Formula for Percentage Increase
Here’s the standard formula:
\( \text{Percentage Increase} = \left( \frac{\text{New Value} – \text{Original Value}}{\text{Original Value}} \right) \times 100 \)
Where:
-
New Value is the updated or increased amount.
-
Original Value is the base or initial amount.
Step-by-Step Example
Example 1:
Suppose the price of a product increased from $50 to $65. What’s the percentage increase?
Step 1: Subtract original from new:
\( 65 – 50 = 15 \)
Step 2: Divide by the original:
\( \frac{15}{50} = 0.30 \)
Step 3: Convert to percentage:
\( 0.30 \times 100 = 30% \)
✅ The price increased by 30%.
Real-World Use Cases
-
Finance: Tracking investment growth over time.
-
E-commerce: Analyzing sales increase during promotions.
-
Education: Understanding grade improvements.
-
Health: Monitoring weight gain or fitness progress.
Common Mistakes to Avoid
-
Using the new value in the denominator. Always use the original value.
-
Forgetting to multiply by 100. This results in a decimal, not a percentage.
-
Not converting units consistently. Ensure both values are in the same units.
