How Can We Help?

How do I calculate a percentage?

Select the "Basic Percentage" calculator, enter your percentage and total amount, then tap "Calculate" to see the result. For example, to find 15% of 200, enter 15 in the percentage field and 200 in the total amount field.

What's the difference between the three calculators?

• Basic Percentage: Calculates what X% of Y is (e.g., 20% of 50 = 10)
• Percentage of Total: Finds what percentage one value is of another (e.g., 25 is 25% of 100)
• Percentage Change: Calculates the percentage increase or decrease between two values (e.g., from 100 to 125 is a 25% increase)

How do I view my calculation history?

Tap the history button (clock icon) at the top of the main screen to view all your past calculations. You can tap any previous calculation to copy it to your clipboard.

Can I change the order of calculators?

Yes! Go to Settings (gear icon) and select "Calculator Order". You can drag and drop the calculators to reorder them according to your preference.
