Tip: $15.21

How is a tip calculated?
Tip = bill before tip × (tip percentage ÷ 100). Total bill = bill + tip; per-person amount = total ÷ people. For a $84.50 pre-tip bill at 18%, the tip is $15.21 and the total is $99.71.
Should you tip before or after tax?
US tipping practices vary. This calculator uses the exact bill amount entered—use the pre-tax subtotal if you prefer to tip on that basis. Check the receipt for automatic gratuities or service charges to avoid accidentally paying twice.
Frequently asked questions
Does this calculator split uneven tips?
No. It assumes each person pays an equal share of the bill and tip. For different orders, calculate each share separately.
Are my numbers stored?
The calculator is designed to run in your browser without sending the amounts to a server; standard site analytics may still record page views.
