Your Receipt

What to Pay

Put on Your Receipt

Amount: -.--
+ Tip: -.--
= Total: -.--
Actual tip percentage is 0%.


Split Totals

One person pays
+ Tip: -.--
= Total: -.--
The remaining person pays
+ Tip: -.--
= Total: -.--
The tip & total do not divide evenly so one person has to pay a different amount.


Enter the amount on your receipt or bill and then adjust how much you want to pay.

First, in the Your Receipt section enter the sub-total or amount on your receipt into the Amount box. You may also enter the tax on your receipt into the Tax box. When you change the amount the desired total will be automatically recalculated.

Second, adjust the What to Pay section by doing one of the following. The Put on Your Receipt section will automatically recalculate after each change.

You may split your total with multiple people by entering the number of people into the Number of People box in the Split section. In some cases the tip & total won't divide evenly so one person will need to pay a different amount than the rest.

More About Tipping

A tip is extra money given to a service worker (server, hair stylists, etc) on top of the total bill. Tips are a way of saying thank you for the service that they have performed. Larger tips signal that the service was above average and smaller tips that the service was poor.

Tipping varies by culture and country. In the US and Canada tipping is a common and expected practice. Not leaving a tip in those countries signifies poor service and may be considered an insult. In Japan tipping is not common or expected. In some countries a tip may be considered a bribe or an insult.

Since a majority of the wonderful visitors to CantMath.com are from the US. Here are five situations where you should consider leaving a tip in the US or Canada.

  • When you receive good service at a restaurant. If you’re not going to complain to management you should leave at least a small tip. Consider giving 15% for good service and more for better service. Not all restaurants are alike though, there is no need to tip at most fast food places.
  • When you are at a bar. Consider giving the bartender a larger tip on the first round of drinks. You should also consider tipping per drink when paying cash. When closing out a tab a 20% tip is considered average. CantMath.com is especially helpful when closing out a tab. Who want’s to math after drinking anyway?
  • When you are at a salon or getting a haircut. If you’re happy with the results leave a 20% tip.
  • When at a hotel tip the bellhop for carrying bags and the housekeeper for cleaning your room. No need for CantMath in this case just leave a few bucks per bag or day.
  • After receiving a ride in a Lyft, Uber, or taxi consider leaving a 15% tip if the ride was good.

Here are three situations where you should absolutely not leave a tip.

  • Never tip a police officer. That’s called bribery and may land you in jail. Sharing what you know about a crime is cool though.
  • At the dentist. They don’t really want all of that loose change around the x-ray machines anyway.
  • When posting bail. I told you not to tip the police officer!

Thanks for visiting! I built this tip calculator because I can’t math under pressure and I hope it has helped you as well. Please share CantMath with your friends!
