  • Tip (rate mode) = tip base x tip rate
  • Total = bill amount + tax + tip
  • Per person due = total / people count
  • Per person tip = tip / people count

FAQ

  • Does custom tip work with tip rate together? No. Once custom tip is entered, custom amount takes priority.
  • What is the difference between pre-tax and after-tax tip basis? Pre-tax uses bill only, while after-tax includes tax in tip base.
  • Is data uploaded? No, all calculations run locally in your browser.
