Enter your bill amount, choose a typical tip percentage (for example 15%, 18%, or 20%), and optionally how many people are paying. The tool shows the tip in the same currency as your bill, the full total including gratuity, and each person’s share when you split evenly.
Pre-tax or total you want the percentage applied to (your currency).
e.g. 15, 18, or 20
Whole number; use 1 if paying alone.
Enter your bill amount, choose a typical tip percentage (for example 15%, 18%, or 20%), and optionally how many people are paying. The tool shows the tip in the same currency as your bill, the full total including gratuity, and each person’s share when you split evenly.
Tip = bill × (tipPercent ÷ 100) Total = bill + tip Per person = total ÷ partySize
Bill £48.60 with 18% tip: tip = 48.60 × 0.18 = £8.75 (rounded to pence), total = £57.35. For 3 people splitting evenly, about £19.12 each. The same numbers apply in dollars for a $48.60 bill.
Multiply the bill by the tip percentage expressed as a decimal. For example, 18% means multiply by 0.18. This tool does that multiplication and rounds to two decimal places for currency-style totals.
People use different conventions. Enter whichever bill total you want the percentage applied to—if you tip on the pre-tax subtotal, type that amount; if you prefer the after-tax figure, type that instead.
Yes. Enter the number of people sharing; the calculator divides the bill-plus-tip total evenly. It does not model separate items or uneven shares.
No currency conversion or tax rules are applied. Amounts stay in whichever currency you typed, for educational arithmetic only.
Restaurant Tip Calculator: Work Out Gratuity and Split the Bill
Leaving a gratuity is a small percentage problem you can sanity-check quickly. This article explains how the arithmetic works for common percentages, how splitting changes what each person pays, and points to ProMathTools’ calculator so you can try your own bill numbers in seconds.
A tip treats the bill as the base amount and scales it by your chosen percentage. Once you know the tip, the amount you actually pay—or the pooled total before dividing—is the bill plus that tip. Rounding to two decimal places matches how many people think about pounds, pence, dollars, and cents for everyday totals, even though real card terminals may round slightly differently.
Tip = bill × (tipPercent ÷ 100). Total with tip = bill + tip. If n people split evenly, each pays total ÷ n.
Suppose the bill is $60.00 and you choose 20%. The tip is 60 × 0.20 = $12.00, so the full total is $72.00. With four friends sharing equally, 72 ÷ 4 = $18.00 each. For £60.00 and 20%, the same steps give £12.00 tip, £72.00 total, and £18.00 each—only the currency symbol changes.
Open the Restaurant Tip Calculator on the tool page, type your bill in the bill field, set the tip percentage you want (for example 18), and set people splitting to 1 or more. The result lines show the tip amount, the overall total including gratuity, and—when more than one person pays—each person’s even share after the tip is included.
