FAQs

How do I calculate a percentage increase?

To find a percentage increase, subtract the original value from the new value, divide by the original value, and multiply by 100. Or simply use our 'Percentage Change' mode!

Can I calculate percentages greater than 100%?

Yes! Percentages can exceed 100%. For example, if a price doubles, it has increased by 100%. If it triples, it has increased by 200%.

What is the difference between specific percentage and percentage change?

Specific percentage (e.g., 'What is 20% of 50?') finds a portion of a whole. Percentage change (e.g., 'Change from 50 to 60') calculates the relative difference between two values over time.
