Split a shared bill
Bill amount 50 $
Tip 18 %
Number of people 2 Result: 9
50 × 18 ÷ 100 = 9 tip 50 + 9 = 59 total 59 ÷ 2 = 29.5 per person The tip is 9, while each person pays 29.50 including their share of the original bill. Do not confuse the tip output with the per-person total.
No extra tip
Bill amount 90 $
Tip 0 %
Number of people 3 Result: 0
90 × 0 ÷ 100 = 0 tip 90 + 0 = 90 total 90 ÷ 3 = 30 per person A zero tip still allows an equal split of the entered bill. Check whether a service charge is already included before deciding what percentage to add.
