Proportional Bill Splitter

Fairly distribute tax and tip based on exactly what each person ordered.

Proportional Bill Splitter

Splitting a restaurant bill evenly isn't fair if one person ordered a $15 salad and another ordered a $50 steak and drinks. This tool calculates the exact proportional burden of taxes and tips based purely on what each individual actually consumed.

How it works (3 Easy Steps):

  1. Look at your final receipt and input the Receipt Subtotal, Tax, and Tip.
  2. Add your friends and input the exact cost of the items they ordered.
  3. We instantly calculate what percentage of the subtotal they represent, and apply that exact percentage to the tax and tip pool so they pay exactly their fair share!
