Splitting evenly assumes everyone ordered roughly the same amount. If one person's meal cost far more or less than the others, splitting by what each ordered is fairer.
How the math works
Three short steps:
Tip = bill × tip %
Total = bill + tip
Per person = total ÷ number of people
A quick mental check: 10% of the bill is just the decimal point moved one place left. Double that for 20%, or halve it and add it to 10% for 15%.
Worked example (in USD)
An $80 bill, a 20% tip, split 4 ways:
Tip: $80 × 20% = $16
Total: $80 + $16 = $96
Per person: $96 ÷ 4 = $24 each.
Common gotchas
- Tip on the pre-tax amount. Custom in many places is to tip on the bill before sales tax, not on the after-tax total. If your bill shows a subtotal, tipping on that is slightly less than tipping on the total shown here — enter the subtotal if that's how you tip.
- Check for an included gratuity. Large parties often have an automatic gratuity (commonly 18–20%) already added. Tipping the full percentage again on top doubles it by accident.
- Delivery and service fees aren't the tip. App and restaurant service fees usually don't go to the person serving or delivering your food.
- Rounding per person. When a split doesn't divide evenly, the per-person figure is rounded to the cent, so the shares can add up to a cent or two over or under the total. Rounding each share up slightly is the usual fix.
- Norms vary by place and service. 15–20% is the common full-service restaurant range in the US; counter service, bars, and other countries follow different customs, and in some places tipping is not expected at all.
