Calculate the percentage increase from one value to another.
The percentage increase formula is:
Percentage Increase = ((New Value - Original Value) / Original Value) x 100
For example, if a price goes from $100 to $150:
((150 - 100) / 100) x 100 = 50% increase
If the result is negative, the value actually decreased. In that case, consider using the Percentage Decrease Calculator.
Percentage increase measures how much a value has grown relative to its original amount. Think of it like tracking your savings account: if you started with $500 and now have $650, the percentage increase tells you the growth rate (30%) rather than just the dollar amount ($150). This makes it easy to compare growth across different scales -- a $10 raise on a $50,000 salary is very different from a $10 raise on a $100 freelance job.
Percentage increase is used in business for revenue growth, in economics for inflation rates, in real estate for property value appreciation, and in personal finance for investment returns. It answers the fundamental question: "By what proportion did this value grow?" Understanding this concept helps you evaluate whether a raise is fair, whether an investment performed well, or whether prices are rising faster than your income.
Formula: Percentage Increase = ((New Value - Original Value) / Original Value) x 100
Example: A product's price went from $80 to $100. What is the percentage increase?
Step 1: Find the difference: 100 - 80 = 20.
Step 2: Divide by the original: 20 / 80 = 0.25.
Step 3: Multiply by 100: 0.25 x 100 = 25% increase.
Another example: Your website traffic went from 1,200 visitors to 3,000 visitors. Increase = ((3000 - 1200) / 1200) x 100 = (1800 / 1200) x 100 = 150% increase.
Important: always divide by the original value, not the new value. Dividing by the new value gives you a different metric (percentage difference from the new value's perspective).
| From | To | % Increase |
|---|---|---|
| 50 | 55 | 10% |
| 100 | 125 | 25% |
| 200 | 300 | 50% |
| 75 | 150 | 100% |
| $45,000 | $48,600 | 8% |
| $1,200 | $1,500 | 25% |
| 500 | 750 | 50% |
| 80 | 100 | 25% |
| 60 | 90 | 50% |
| $2.50 | $3.75 | 50% |
| 1,000 | 2,500 | 150% |
Subtract the original value from the new value, divide the result by the original value, and multiply by 100. The formula is: ((New - Original) / Original) x 100.
The percentage increase from 50 to 75 is 50%. Calculation: ((75 - 50) / 50) x 100 = 50%.
Percentage change is the broader term that covers both increases and decreases. A positive percentage change is an increase, and a negative percentage change is a decrease. The formula is the same.
Yes. A 100% increase means the value doubled. A 200% increase means it tripled. For example, going from 40 to 120 is a 200% increase because (120 - 40) / 40 x 100 = 200%.
If a tax rate goes from 10% to 15%, it increased by 5 percentage points, but the percentage increase is 50% (because 5/10 x 100 = 50%). Percentage points measure the absolute difference; percentage increase measures the relative change.
Use the same formula: ((New Salary - Old Salary) / Old Salary) x 100. If your salary went from $52,000 to $55,120, the raise is ((55120 - 52000) / 52000) x 100 = 6%.
They use the same formula -- both measure relative growth from a base value. Markup specifically refers to price increases added to cost. The math is identical, but the context differs.
Percentage increase is undefined when the original value is zero because you would be dividing by zero. In such cases, you can only describe the change in absolute terms rather than as a percentage.
