Calculate a tip with Siri

Quick answer

"What's a 20 percent tip on 45 dollars" and Siri answers the tip and, if you ask, the total. Say "what's 18 percent of 62" for a different rate. Pair it with splitting the bill to settle up quickly with a group.

If Siri doesn't get it

These are plain calculations and need no internet. If Siri mishears the numbers, say the amount and percentage slowly and clearly.
