What This Calculator Does

This all-in-one calculator solves five types of percentage problems:

1. X% of a number (e.g., “What is 20% of 150?”)
2. Percentage ratio (e.g., “What percent is 25 of 200?”)
3. Reverse calculation (e.g., “50 is 25% of what number?”)
4. Percentage difference (e.g., “What’s the difference between 80 and 100?”)
5. Percentage increase/decrease (e.g., “If a price rises from $50 to $75, what’s the % increase?”)

Practical Uses for Each Tool

1. Calculating “X% of a Number”

• Use cases:
• Determining sales tax (e.g., “7% tax on a $90 purchase”)
• Calculating tips at restaurants
• Measuring discounts (e.g., “30% off a $200 jacket”)
• Example:
  To find 15% of 300, enter 15 in the first field and 300 in the second. The result: “15% of 300 is 45.”

2. Finding Percentage Ratios

• Use cases:
• Analyzing exam scores (e.g., “What percent did I score if I got 45/60?”)
• Budgeting (e.g., “Rent is $1,200 of a $4,000 income—what % is that?”)
• Example:
  If you answer 18 questions correctly out of 24, the calculator shows “18 is 75% of 24.”

3. Reverse Calculation (Finding the Original Number)

• Use cases:
• Determining pre-discount prices (e.g., “$70 is 30% off—what was the original price?”)
• Solving “half of what number” problems in math
• Example:
  If 60 is 40% of a number, the tool calculates “60 is 40% of 150.”

4. Percentage Difference

• Use cases:
• Comparing prices (e.g., “Is Product A ($120) significantly cheaper than Product B ($150)?”)
• Analyzing data changes in science experiments
• Example:
  Comparing 80 and 100 yields a 22.22% difference.

5. Percentage Increase/Decrease

• Use cases:
• Tracking stock market gains/losses
• Measuring weight loss or fitness progress
• Evaluating salary raises
• Example:
  If a stock jumps from $200 to $250, the calculator shows a 25% increase.
