Tip Calculator

Split the check without a group-chat argument

Tipping math is easy until six people, a shared appetizer, and a tax line get involved. This tip calculator takes the bill, an optional tax amount, a tip percent, and a headcount. It returns the tip, the grand total, and each person’s share. The point is speed at the table—not a lecture on hospitality economics.

All of the arithmetic stays on your phone. You are not creating an account or uploading a receipt. Change the percent and the per-person number updates immediately, which is useful when someone wants 18% and someone else wants 22%.

How the tip is calculated

Tip equals bill × (percent ÷ 100). If you enter tax separately, the grand total is bill + tax + tip. Each person pays grand total ÷ people. If you leave tax at zero, the tool assumes the bill field is the amount you want to tip on—use that when the receipt’s subtotal is what you care about.

Rounding is to the nearest cent. In a group of three, a third of a penny has to land somewhere; the displayed per-person amount is rounded, so the last person to pay Venmo may need to cover a one-cent remainder. For large groups, rounding each share up by a few cents avoids an awkward shortfall for whoever pays the card.

How to use it at the table

Type the pre-tax subtotal if you tip before tax. Add the tax line if you want the total to match the bottom of the receipt. Set people to the number of wallets, not the number of entrees—kids or guests being treated should not be in the divisor. If an 18% service charge is already printed, set tip to 0 and only add more if you intend to.

Delivery apps sometimes collect a tip that never reaches the driver in the way you expect, and they also add service fees. This calculator cannot see those fees. Use it for the restaurant line items you can actually verify.

Examples

An $86 dinner, 20% tip, two people: $17.20 tip, $103.20 total, $51.60 each if tax is already inside the $86 or omitted. A $45 lunch at 18% is $8.10 tip and $53.10 total. A $120 group check at 15% with four people is $18 tip, $138 total, $34.50 each.

If that $120 check also has $10 tax and you tip 20% on the $120 subtotal, tip is $24 and the total becomes $154, or $38.50 each. Entering $130 as the “bill” and tipping 20% would incorrectly tip on tax as well.

Etiquette is local; math is not

U.S. full-service norms differ from cafés, food trucks, and countries where service is included. The calculator will happily compute a 0% or 25% tip. It will not tell you which one matches the room. If service was poor, people still often tip something and speak to a manager rather than using the percent field as a punishment device that hurts the wrong worker.

For recurring team lunches, agree on a percent once and reuse it. The percentage calculator on KindCalc is there if you need a custom rate that is not 15, 18, or 20.

Frequently asked questions

Should I tip on the pre-tax or post-tax amount?

Custom varies. Many people tip on the pre-tax subtotal. If your receipt already includes tax, enter the pre-tax amount in the bill field and put tax in the tax field so the tip is not inflated.

What is a standard tip in the United States?

Full-service restaurants commonly see 15–25%, with 20% as a frequent default for good service. Cafés, takeout, and delivery follow different norms. The calculator does not tell you what is fair; it only does the arithmetic.

How do you split a bill evenly?

Add tip (and tax if you include it) to the bill, then divide by the number of people. This tool does even splits. Uneven orders are better handled by itemizing on a separate app or paying what you ordered plus a share of tip.

Does the calculator store my restaurant bills?

No. Everything runs in your browser and disappears when you leave the page.

How do I handle a service charge already on the check?

If an automatic gratuity is already included, set the tip percent to 0 unless you want to add more. Double-tipping is a common mistake on large-party checks.
