How do I calculate percentage change?

Use Percent change mode. Enter the old value and the new value; the calculator uses (new - old) / old × 100.

Can I calculate discounts and tips?

Yes. Discount mode calculates the final sale price and savings, while Tip mode adds the tip percentage to the bill.

No. The calculator runs in your browser, so values are not uploaded or stored by Anything Tools.
