How it works

Gratuity is amount × percentage ÷ 100, the total adds gratuity to the amount, and both values divide by the diner count. Currency symbols and line labels affect display only.

  • A 15% gratuity, 50 amount, and one diner form the editable starting example.
  • Service charge, tax, and local rounding rules are not inferred.

Worked example

Dinner Bill Split
Calculate 18% tip on an $85 bill split 4 ways
Input
											Amount: 85
Tip percent: 18
Split: 4
Output
												Bill Amount: $85.00
Tip (18%): $15.30
Total: $100.30
Split 4 ways: $25.07 per person
Tip per person: $3.82

When to use this

Restaurant bills split gratuity, delivery receipts estimate a percentage tip, and group dinners compare total with per-person cost.

Edge cases

  • A zero-person split would divide by zero and is invalid.
  • A negative gratuity is arithmetic rather than a normal tip recommendation.
  • Rounding each share to cents can leave a one-cent remainder that is not allocated.
