How to Calculate Percentage Increase
Calculating a percentage increase is a fundamental mathematical skill used to track growth, inflation, financial gains, and stat shifts across nearly any field, from personal finance to sales reporting. Because this tool doubles as a general-purpose percentage improvement calculator, you can also use it whenever you need to work out what percent greater one number is than another, not just for classic "percentage increase" problems. To calculate it manually, you compare the final value with the starting baseline and evaluate the growth factor.
When Would I Use a Percentage Increase?
- Salary raises: Evaluating the boost in monthly wages or salaries relative to the base pay rate.
- Investment growth: Tracking total return rate improvements on mutual funds, stocks, or savings interest over time.
- Price markups: Identifying retail pricing surges or inflation rates on physical items and SaaS subscriptions.
Worked Example: Savings
Suppose your monthly savings grew from $200 to $250. Let's calculate the percentage difference relative to the initial savings value:
- Difference: 250 - 200 = 50
- Divide by starting savings: 50 / 200 = 0.25
- Multiply by 100 to get percentage: 0.25 × 100 = 25% increase.
Worked Example: Business Revenue
A store's quarterly revenue rose from $40,000 to $52,000. Here's how to find the percentage increase, and what percent greater the new figure is than the old one:
- Difference: 52,000 - 40,000 = 12,000
- Divide by starting revenue: 12,000 / 40,000 = 0.3
- Multiply by 100: 0.3 × 100 = 30% increase — the new revenue is 30% greater than the old one.
Percentage Increase FAQ
Q: How do I calculate percentage increase in Excel?
Use the formula =(NewValue-OldValue)/OldValue in an empty cell, and then format the cell as a percentage style using the Home toolbar.
Q: What is the difference between percentage increase and percentage points?
Percentage increase refers to the rate of change relative to the original value, while percentage points refer to the simple absolute subtraction between two percentage values.
Q: Can percentage increase be more than 100%?
Yes. Any final value that is more than double the starting value represents an increase of greater than 100%.
Q: What does it mean when one number is a certain percent greater than another?
Saying one number is, for example, 25% greater than another means the same thing as a 25% increase — you're measuring how much bigger the new value is relative to the original. This calculator works as a percentage improvement calculator for exactly that kind of comparison, whether you're comparing prices, scores, or performance metrics.
