How to quickly calculate a tip on your iPhone

Maybe you like to leave a tip for the service you receive at different businesses, but you're never quite sure of the math. Well, with your iPhone handy, you don't have to be. Using the iPhone's built-in calculator app or Siri, you can quickly discover what the proper amount to leave should be.

Here's how you can use your iPhone to calculate a tip.

How to use Siri to calculate a tip

Siri is certainly the fastest way to calculate the tip with your iPhone.

  1. Press and hold down on your iPhone's Home button or say Hey Siri.
  2. Say, for example, "$10.50 with a 20% tip". Importantly, you'll need to say the amount on your bill properly, so instead of saying "Ten-fifty with a twenty percent tip," you'll need to say "ten dollars and fifty cents with a twenty percent tip."
  3. Get the amount you need to tip and the total from Siri's readout.

How to get the correct tip with the Calculator app

If perhaps you don't want to shout into your phone in a crowded restaurant just to get a tip, you can always use the calculator app.

  1. Open Calculator on your iPhone.
  2. Enter the amount on your bill. In this example, we'll again use $10.50.
  3. Tap the + button.

  1. Enter the percentage you want to tip.
  2. Tap the % button.
  3. Tap the = button

If you need to know the exact amount you're adding to your bill, take the final amount from Step 6, subtract the original amount on your bill, and there's your answer. Note that the calculator app might not always give you clean results, you may need to round up or down at your preference.

This is just one of the many ways using Calculator can help you day-to-day. For more pointers on using Calculator, you can check out our guide.

  • Why even give a tip??
  • I would like to think this is sarcastic, that or it's just not a standard thing in your country. Many waiters receive a very small wage, tips are what make their wage sustainable. It also means that if you're a terrible waiter, it will show in how much you earn, whereas if you put 110% effort into your job and make people as happy as possible, you'll reap the rewards
  • It's ridiculous how people today need instructions on how to use a calculator for simple arithmetic. In fact calculating tips is easy enough to do in your head if you got pass grade 5.
  • This is somewhat offensive, given that some people including myself struggle significantly with mathematics, especially mental arithmatic. It's these kind of comments which result in people having mathematical anxiety, which you can read up about here: Some people struggle with English, I have no problem with English, but I don't start going on to other people about how they should be as good at it as I am, because I don't know how much of a struggle it is for them. Everyone's mind works differently
  • iMore won't let me edit a typo (pass->past) without having to accept 784469.json first and then it fails anyway.
  • I think you mean the multiplication sign, not the addition sign, yes? Or maybe I'm missing something here....
  • Great tip! Forgive the pun. The SIRI version, however, does not work in the UK with pounds sterling. When I say to SIRI "ten dollars and fifty cents with a twenty percent tip" it works fine but when I say "ten pounds and fifty-pence with a 20% tip" SIRI says: "OK, I found this on the web for '£10 and 50p with a 20% tip': ". then SIRI lists web suggestions which do not include a tip calculation. Ho hum. Us Brits lose out again :(
  • As a Brit myself that sucks. I've not tested it myself, but next time try saying "gratuity" instead of tip and see if that helps
