Why this result

  • 8.25% tax on $64.80 adds $5.35.
  • 18% tip on the subtotal adds $11.66.
  • The full total is $81.81, or $27.27 each across 3 people.

Assumptions

  • Tip is calculated from the subtotal before tax.
  • The split uses equal shares and rounds to the nearest cent for display.

Use cases

Useful when the bill is moving fast

  • Check the all-in total before you confirm payment.
  • See how a different tip rate changes each person's share.
  • Keep tax and tip visible as separate amounts instead of one opaque total.

Calculation rules

What the calculator assumes

  • Tip is calculated from the subtotal before tax.
  • Each person pays an equal share of the rounded display total.
  • Blank tax defaults to zero if you only need tip splitting.
