Percentage Calculator Tips & Tricks
Quick Mental Math: To calculate 10% of any number, simply move the decimal point one place to the left. For 20%, double the 10% result.
Percentage vs Percentage Points: Remember that percentage points are different from percentages. A change from 10% to 15% is a 5 percentage point increase, but a 50% relative increase.
Reverse Calculations: If you know the final amount after a percentage change, you can find the original amount using our reverse percentage calculator mode.
Precision Matters: For financial calculations, use higher decimal precision to ensure accuracy in your percentage calculations.
Frequently Asked Questions About Percentage Calculations
How do I calculate what percentage one number is of another?
To find what percentage A is of B, divide A by B and multiply by 100. Our percentage calculator automates this with the "What percent is A of B?" mode.
What's the difference between percentage increase and percentage points?
Percentage increase is relative (e.g., from 10% to 15% is a 50% increase), while percentage points are absolute (the same change is 5 percentage points).
How do I find the original price before a discount?
Use our reverse percentage calculator mode. Enter the final price and the discount percentage to find the original price before the discount was applied.
Can I use this percentage calculator for business calculations?
Absolutely! Our percentage calculator is perfect for business use, including profit margin calculations, tax computations, discount pricing, and financial analysis.
