How to use it

  1. Enter the subtotal from the receipt — the amount before tax and tip.
  2. Enter the sales tax rate and the tip percentage you want to leave.
  3. Choose whether the tip applies before or after tax, then set the number of people.

Examples

Four friends at dinner

Subtotal $120, 8% tax ($9.60) and an 18% pre-tax tip ($21.60) makes $151.20 in total, or $37.80 each.

Tipping on the taxed amount

The same bill with the tip calculated after tax gives a $23.33 tip, a $152.93 total and $38.23 per person.

What goes into each share

Tax is the subtotal multiplied by your local rate. The tip is either a percentage of the subtotal (pre-tax) or of the subtotal plus tax (post-tax). Everything is added together and divided evenly.

An even split is simplest when everyone ordered similar amounts. If orders were very different, enter each person's items as their own subtotal and run the calculation per person with “Number of people” set to 1.

per person = (subtotal + tax + tip) ÷ people

Frequently asked questions

Why does the tip change when I switch to after-tax?

An after-tax tip is a percentage of a larger number (subtotal plus tax), so it's slightly bigger. With 8% tax and an 18% tip, the difference is about 1.4% of the subtotal.

What if the service charge is already included?

Set the tip to 0% and add the service charge to the subtotal, or check the receipt — many restaurants add a service charge automatically for large groups.

Why don't the shares add up exactly to the total?

Shares are shown to the cent, so a total that doesn't divide evenly can be off by a cent or two. One person can simply cover the extra cent.
