How a service charge changes the total
A service charge is added by the business before the bill is paid. It may be a percentage or fixed dollar amount. This calculator adds that charge before showing the final total and split.

Formula
How this calculator works
- Charge = bill subtotal × charge rate + fixed charge
- Tax = bill subtotal × tax rate
- Total = bill subtotal + tax + charge + optional extra tip
- Each person pays = total ÷ number of people
Receipt check
Read the service-charge line before you tip
Service charges are common on banquet, hotel, spa, and event bills, as well as some restaurant checks. Look for wording such as “service charge,” “administrative fee,” or “house charge.” The label alone does not tell you whether the amount is a voluntary tip.
Next step
Ask when the receipt is unclear
If you cannot tell whether the charge is required or whether an additional tip is expected, ask the business before paying. This calculator keeps the service charge and any extra tip separate so you can see both amounts.
Examples
Common bill examples
These examples are quick estimates. Your receipt may use different tax or charge wording.
$100 bill with 18% service charge
Service charge: $18.00. With 8% tax and no extra tip, the estimated total is $126.00.
Large group split
A $240 bill with an 18% service charge, 8% tax, and 6 people is about $50.40 each before any optional extra tip.
Optional extra tip
If service was excellent, you can add a small extra tip amount and compare the new per-person total.
When to add an extra tip
When a receipt lists a charge as required, include it in the bill before deciding whether to add a voluntary tip. The calculator keeps the amounts separate so you can decide clearly.
Accuracy note
USTipCalc does not decide whether a service charge goes to staff. It only helps estimate the bill. If the receipt is unclear, ask the restaurant, hotel, or business.
