A quick decision brief for this specific tool
Inputs that matter
Bill amount, selected or custom non-negative tip percentage, whole-number party size from 1 to 100, and optional per-person rounding increment
Output to expect
Raw and rounded tip/total, per-person shares, rounding addition, effective tip percentage, comparisons, and a reproducible split table
How it works
Tip equals bill times percentage; optional rounding ceilings each person’s total to the chosen increment and reports the exact amount added
- Tipping customs, taxes, and mandatory service charges vary by place; confirm the bill before paying.
- Rounding changes the effective tip, so use the disclosed rounded addition rather than assuming the selected percentage remains exact.

How it works
Updated August 2026Tip Amount
The tip is calculated from the bill amount you enter. Customs, service charges, and whether people use pre-tax or post-tax totals vary by location, so confirm the actual bill.
Tip = Bill Amount × (Tip % ÷ 100)Per-Person Split
When splitting the bill, divide the total (bill plus tip) evenly among the number of diners.
Per Person = (Bill + Tip) ÷ Number of PeopleOptional Per-Person Rounding
When enabled, each person's total is rounded upward to the selected increment. The calculator reports the added amount and recalculates the effective tip.
Rounded share = ceil(Unrounded share ÷ Increment) × IncrementUpdated: August 2026
Example Scenarios
A group of four friends splits a $120 restaurant bill with an 18% gratuity.
Bill: $120Tip: 18%People: 4
→ Tip: $21.60, total: $141.60, $35.40 per person
A solo diner wants to leave a generous 20% tip on a quick-service lunch.
Bill: $24.50Tip: 20%
→ Tip: $4.90, total: $29.40
A solo diner compares the exact total with an optional rounded payment and checks the resulting effective tip.
Common Mistakes to Avoid
Common Mistakes to Avoid
Tipping on the post-tax total
Standard practice in the US is to calculate tip on the pre-tax subtotal. Tipping on tax inflates the gratuity unnecessarily.
Forgetting to split tip when dividing the bill
When splitting evenly, divide the total including tip — not just the food subtotal. Each person should cover their share of both bill and gratuity.
FAQ
For sit-down table service, 15–20% of the pre-tax bill is standard. 18% is a common default for good service; 20% or more for exceptional service. Counter service and takeout often use 10–15% or no tip, depending on local custom.
Standard US practice is to calculate tip on the pre-tax subtotal, not the total after sales tax. Tipping on tax slightly overstates the gratuity, though some people round up on the post-tax total for simplicity.
Add the tip to the bill first to get the grand total, then divide by the number of people. For a $120 bill with 18% tip ($21.60), the total is $141.60 — split four ways, each person pays $35.40.
Food delivery tips typically range from 15–20% of the order subtotal, with a minimum of $3–5 for small orders. Increase the tip for large orders, bad weather, or long distances.
In the US, gratuity is traditionally calculated on the pre-tax food and beverage subtotal. Multiplying the post-tax total by your tip percentage slightly over-tips because sales tax is not a service charge. Either method is acceptable if you prefer rounding up for convenience.
