Tip Calculator

The Tip Calculator takes a bill amount, a tip percent, and a party size, then returns the tip amount, the tipped total, and each person's share when the party splits evenly. Enter the three fields and read the three results from the same formula every time.

Calculate tip from bill and percent

Tip amount equals the bill times tip percent divided by 100. A bill of 86.50 at 18 percent tip produces 15.57 in tip. The Tip Calculator uses that product as the tip line before adding it to the bill.

tip = bill × (tip% ÷ 100)

Example: 86.50 × (18 ÷ 100) = 15.57.

Calculate the tipped total

Total equals bill plus tip amount. With the same 86.50 bill and 15.57 tip, the tipped total is 102.07. The Tip Calculator reports that sum as the amount due before any separate tax or service charge not entered in the bill field.

total = bill + tip

Example: 86.50 + 15.57 = 102.07.

Split the total across people

Per person equals the tipped total divided by the number of people when the party splits evenly. With a total of 102.07 and 4 people, each share is 25.5175 before ordinary currency rounding on the screen. Enter 1 person to skip splitting.

per person = total ÷ people

Example: 102.07 ÷ 4 ≈ 25.52 when rounded to cents on display.

Keep bill, tip percent, and party size consistent

Use the pre-tip bill in the bill field unless local custom tips on post-tax totals; mixing those conventions changes the tip line. Tip percent is a percent, not a decimal already divided by 100. Party size must be a positive whole number.

The Tip Calculator does not invent tax, automatic gratuity, or coupon adjustments. Add those into the bill figure first if they belong in the tip base for the venue.

Frequently asked questions

Summary

The Tip Calculator returns tip amount, tipped total, and an even per-person share from bill, tip percent, and party size. The worked example 86.50 at 18 percent for 4 people yields tip 15.57, total 102.07, and about 25.52 per person when rounded to cents.
