Frequently Asked Questions
1. What’s the difference between percentage change and absolute change?
Percentage change shows the relative difference expressed as a percentage (e.g., 25% increase), while absolute change shows the actual numerical difference (e.g., $250 increase). Our calculator displays both so you get complete understanding of the change.
2. How do I calculate compound percentage changes?
Use our Compound Changes calculator! Instead of trying to manually combine multiple percentage changes (which doesn’t work by simple addition), input each value change with its type (increase/decrease). Our tool accurately calculates the true overall percentage change and final value.
3. When should I use the Inverse Calculator?
The Inverse Calculator is perfect when you know the original value and the percentage change, but need to find the resulting value. Common uses include:
Determining sale prices after discounts
Calculating salaries after raises
Finding exam scores after percentage adjustments
Determining budget amounts after percentage cuts
