What is percentage increase?
Percentage increase is a measure of how much a value has grown relative to its original value, expressed as a percentage. It answers the question: "By what percentage has this value increased?" This metric is particularly useful because it provides a standardized way to compare growth across different scales and contexts.
Unlike absolute increase, which tells you the actual difference between two numbers, percentage increase expresses this change relative to the starting point. This makes it easier to compare increases across different magnitudes. For example, a $50 increase means different things if the original price was $100 (50% increase) versus $1,000 (5% increase).
Percentage increase is always calculated from an original (starting) value to a new (final) value. The result tells you what percentage of the original value the increase represents, providing valuable insight into the relative magnitude of change.
Percentage increase formula: How to calculate percent increase
The percentage increase formula and percent increase formula are straightforward and follow a consistent mathematical pattern. Learning how to calculate percent increase using the formula is essential for accurate calculations:
Percentage Increase Formula:
Percentage Increase = ((New Value - Original Value) / Original Value) × 100
Or more simply: Percentage Increase = (Difference / Original Value) × 100
The steps to calculate percentage increase using this percentage increase formula step by step are:
- Calculate the difference: Subtract the original value from the new value
- Divide by original: Divide the difference by the original value to get a decimal
- Multiply by 100: Convert the decimal to a percentage by multiplying by 100
Percent increase formula example: A product's price increases from $80 to $120
Step 1: Difference = $120 - $80 = $40
Step 2: Divide = $40 / $80 = 0.50
Step 3: Percentage = 0.50 × 100 = 50%
The result shows that the price has increased by 50%, meaning the new price is 150% of the original price (100% original + 50% increase). This is a percent increase example that demonstrates the stepwise method for percent increase calculator.
This percentage increase calculation example illustrates the stepwise method for percent increase calculator. You can use this same percent increase calculation method for any values to find the percentage increase calculation.
How to calculate percent increase in Excel
Calculate percent increase in Excel using built-in functions. Here are several methods for finding percentage increase in Excel:
Method 1: Using Formula
Enter the formula: =((B2-A2)/A2)*100
Where A2 is the original value and B2 is the new value. This calculates the percentage increase calculation directly.
Method 2: Using Percentage Format
Enter: =(B2/A2-1) and format the cell as percentage
This method automatically displays the result as a percentage without multiplying by 100.
Method 3: Using SUMPRODUCT for Multiple Values
For calculating percentage increase over time or multiple periods, use array formulas or the SUMPRODUCT function to calculate cumulative percentage increases.
These Excel methods provide the same results as our online percentage increase calculator, but our calculator is faster and doesn't require formula knowledge. However, understanding how to calculate percentage increase using formula in Excel is valuable for spreadsheet analysis.
Percent increase vs absolute increase: Understanding the difference
Understanding the difference between percent increase and absolute increase is crucial for accurate data interpretation. Both metrics provide valuable information, but they serve different purposes. The percent increase vs absolute increase comparison helps you choose the right metric for your analysis.
Absolute Increase
Absolute increase is the actual numerical difference between the new and original values:
Absolute Increase = New Value - Original Value
Percentage Increase
Percentage increase expresses the change relative to the original value:
Percentage Increase = ((New Value - Original Value) / Original Value) × 100
Example Comparison:
Scenario A: Price increases from $20 to $30
- Absolute Increase: $30 - $20 = $10
- Percentage Increase: ($10 / $20) × 100 = 50%
Scenario B: Price increases from $200 to $210
- Absolute Increase: $210 - $200 = $10
- Percentage Increase: ($10 / $200) × 100 = 5%
Both scenarios have the same absolute increase ($10), but very different percentage increases (50% vs 5%). This demonstrates why percentage increase is valuable for comparing changes across different scales.
Real-world examples: Percentage increase calculation example
Calculating salary increase percentage
An employee's salary increases from $45,000 to $52,000 per year. This is a common example of percentage increase in salary.
Percentage Increase = (($52,000 - $45,000) / $45,000) × 100 = ($7,000 / $45,000) × 100 = 15.56%
This represents a 15.56% salary increase, which is substantial and meaningful for the employee. Calculating salary increase percentage helps employees understand their raise in relative terms.

A city's population grows from 250,000 to 287,500 residents over five years. This demonstrates population growth rate calculation.
Percentage Increase = ((287,500 - 250,000) / 250,000) × 100 = (37,500 / 250,000) × 100 = 15%
The population has increased by 15%, indicating significant growth that may require infrastructure planning. This percentage increase over time shows cumulative growth.
Percent increase in investment
An investment portfolio grows from $50,000 to $72,500 over two years. This is an example of how to calculate percent increase in investment value.
Percentage Increase = (($72,500 - $50,000) / $50,000) × 100 = ($22,500 / $50,000) × 100 = 45%
The percent increase in investment is 45%, representing strong portfolio performance. Understanding percent increase in investment helps investors evaluate returns.
Inflation rate calculation
The price of a basket of goods increases from $100 to $108 over one year. This demonstrates inflation rate calculation.
Percentage Increase = (($108 - $100) / $100) × 100 = ($8 / $100) × 100 = 8%
This represents an 8% inflation rate. Inflation rate calculation is essential for understanding purchasing power changes. Percentage increase calculation for inflation rates helps track economic trends.
Sales Revenue Growth
A company's quarterly sales increase from $1.2 million to $1.68 million.
Percentage Increase = (($1,680,000 - $1,200,000) / $1,200,000) × 100 = ($480,000 / $1,200,000) × 100 = 40%
A 40% increase in sales revenue represents strong business growth and successful performance.
How to calculate specific percentage increases
Understanding how to calculate 10% increase, adding 5% increase to a number, and how to add percentage increase to a number is useful for quick calculations and reverse engineering problems.
What is a 50 percent increase?
A 50 percent increase means the new value is 150% of the original value (100% + 50% = 150%).
Example: If a price increases by 50% from $100, the new price is $150.
Formula: New Value = Original Value × (1 + 50/100) = Original Value × 1.50
How to calculate 10% increase
How to calculate 10% increase: Multiply the original value by 1.10 (or add 10% of the original value).
Example: If a salary increases by 10% from $50,000, the new salary is $55,000.
Formula: New Value = Original Value × 1.10 = $50,000 × 1.10 = $55,000
Adding 5% increase to a number
When adding 5% increase to a number, multiply by 1.05 or add 5% of the original value.
Example: Adding 5% increase to a number like $200: $200 × 1.05 = $210
This method of how to add percentage increase to a number works for any percentage: multiply by (1 + percentage/100).
These calculations demonstrate adding multiple percentages together and how to add percentage increase to a number. Our calculator can verify these calculations and help you understand the relationship between percentage increases and final values.

Percentage increase and decrease explained
Understanding percentage increase and decrease is crucial for comprehensive data analysis. Our calculator serves as a percentage increase and decrease calculator, helping you understand both concepts. While this tool focuses on increases, it can also identify decreases.
Percentage Increase
Percentage increase occurs when the new value is greater than the original value. The formula is:
Percentage Increase = ((New Value - Original Value) / Original Value) × 100
Percentage Decrease
Percentage decrease occurs when the new value is less than the original value. The percent decrease calculator formula is similar but results in a negative percentage or can be calculated as:
Percentage Decrease = ((Original Value - New Value) / Original Value) × 100
Key Differences
The difference between percent increase and absolute increase applies to decreases as well. Understanding percent increase and decrease formulas helps you interpret changes correctly:
- Increase: New value > Original value (positive percentage)
- Decrease: New value < Original value (negative percentage or positive decrease)
- No change: New value = Original value (0%)
When using our calculator, if the new value is less than the original value, the result will be negative, indicating a percentage decrease. For dedicated calculate percentage decrease calculations, you can use this tool by ensuring your new value is less than the original value. The percent increase and decrease formulas are mathematically related but represent opposite changes.
Special cases and considerations
When Original Value is Zero
If the original value is zero, percentage increase cannot be calculated because division by zero is undefined. Any positive new value represents growth from nothing, which is mathematically infinite as a percentage but practically means the value has appeared.
Negative Values
If the new value is less than the original value, the result is negative, indicating a percentage decrease rather than an increase. Our calculator will identify when this occurs and provide appropriate interpretation.
Large Percentage Increases
When percentage increase exceeds 100%, it means the value has more than doubled. For example, a 200% increase means the new value is three times the original value (100% original + 200% increase = 300% of original).
Small Increases
Small percentage increases (less than 5%) may seem insignificant but can be meaningful in contexts like interest rates, inflation, or precision measurements. Always consider the context when interpreting results.
Frequently Asked Questions
Percentage increase measures how much a value has grown relative to its original value. It is calculated by dividing the difference between the new and original values by the original value, then multiplying by 100. For example, if a price increases from $100 to $120, that is a 20% increase.
To calculate percentage increase: Subtract the original value from the new value to get the absolute increase. Then divide this difference by the original value and multiply by 100. Formula: ((New Value - Original Value) / Original Value) × 100. For example: ((150 - 100) / 100) × 100 = 50%.
Absolute increase is the actual difference between two values (new value - original value). Percentage increase expresses this difference as a percentage of the original value. For example, if a value increases from 50 to 75, the absolute increase is 25, and the percentage increase is 50%.
No, percentage increase cannot be negative. If the new value is less than the original value, that represents a percentage decrease, not an increase. Our calculator will indicate when the result is actually a decrease.
In Excel, use the formula: =((B2-A2)/A2)*100 where A2 is the original value and B2 is the new value. Alternatively, format the result as a percentage: =((B2-A2)/A2) and apply percentage formatting. You can also use: =(B2/A2-1)*100 for the same result.
Percentage increase cannot be calculated when the original value is zero, as division by zero is undefined. In such cases, any positive new value represents an infinite percentage increase mathematically, but practically it means the value has gone from nothing to something.
Percentage increase is commonly used to measure price changes, salary raises, population growth, revenue growth, sales increases, investment returns, and performance improvements. It helps compare growth across different scales and time periods.
What constitutes a "good" percentage increase depends on context. A 5% salary increase might be good, while a 5% stock price increase might be modest. Generally, any positive increase represents growth, but the significance varies by industry, time period, and baseline values.
If you know the new value and the percentage increase, calculate the original value using: Original Value = New Value / (1 + Percentage Increase / 100). For example, if the new value is 120 and the increase was 20%, the original value is 120 / 1.20 = 100.
This calculator is specifically for percentage increase. If the new value is less than the original value, the calculator will indicate it is a decrease. For dedicated percentage decrease calculations, you may want to use a percentage decrease calculator or ensure your new value is less than the original.
To calculate percent increase in investment: Use the formula ((Final Value - Initial Investment) / Initial Investment) × 100. For example, if you invested $10,000 and it grew to $12,500, the percent increase is (($12,500 - $10,000) / $10,000) × 100 = 25%. This helps evaluate investment performance and returns.
To calculate a 10% increase, multiply the original value by 1.10 (or add 10% of the original value). For example, if a salary increases by 10% from $50,000, the new salary is $50,000 × 1.10 = $55,000. The formula is: New Value = Original Value × (1 + 10/100) = Original Value × 1.10.
To calculate percentage increase in salary: Subtract your old salary from your new salary, divide by your old salary, then multiply by 100. Formula: ((New Salary - Old Salary) / Old Salary) × 100. For example, if your salary increases from $45,000 to $52,000, the increase is (($52,000 - $45,000) / $45,000) × 100 = 15.56%.
To calculate population growth rate: Use the percentage increase formula. Subtract the original population from the new population, divide by the original population, then multiply by 100. For example, if a population grows from 250,000 to 287,500: ((287,500 - 250,000) / 250,000) × 100 = 15% growth rate.
To calculate inflation rate: Use the percentage increase formula on price changes. Subtract the original price from the new price, divide by the original price, then multiply by 100. For example, if prices increase from $100 to $108: (($108 - $100) / $100) × 100 = 8% inflation rate. This measures purchasing power changes over time.
The steps to calculate percentage increase are: 1) Calculate the difference by subtracting the original value from the new value, 2) Divide the difference by the original value to get a decimal, 3) Multiply by 100 to convert to a percentage. Formula: ((New Value - Original Value) / Original Value) × 100.
To add a percentage increase to a number: Multiply the original number by (1 + percentage/100). For example, to add a 5% increase to $200: $200 × (1 + 5/100) = $200 × 1.05 = $210. Alternatively, calculate 5% of $200 ($10) and add it to get $210. This method works for any percentage increase.
