Tip Calculator

The tip amount is simply the bill amount multiplied by your chosen tip percentage — a $50 bill with an 18% tip works out to $50 × 0.18 = $9.00. The total bill is then the original bill amount plus that tip amount. If you're splitting the bill between multiple people, both the tip and the total are divided evenly by the number of people entered, giving you a per-person tip and a per-person total that includes their even share of both the original bill and the tip.

It depends heavily on context, region, and local custom, since tipping norms vary widely. In the United States, 15-20% is the commonly expected range for full-service restaurant dining, with 20% or more often considered generous or standard for particularly good service, and 10% sometimes used as a lower baseline for mediocre service in contexts where tipping is still customary. Many other countries have very different norms — some include service charges automatically and consider additional tipping unusual, while others expect little to no tip at all. When in doubt, a 15-20% tip is a reasonably safe default in tip-customary contexts like US restaurant dining, but always defer to the specific local and situational norm you're in.

There's genuine disagreement on this even among etiquette guides — tipping on the pre-tax subtotal is the more traditional and, by many etiquette authorities' reasoning, more 'correct' approach, since sales tax isn't part of the service being tipped for. In practice, many people simply tip on the total bill amount printed at the bottom of the receipt (which usually already includes tax) purely out of convenience, since it avoids needing to separately identify the pre-tax subtotal. This calculator lets you enter whichever bill amount you prefer as the base — pre-tax subtotal or post-tax total — and calculates the tip and split from whatever figure you provide.

This calculator divides both the tip amount and the total bill (original amount plus tip) evenly across the number of people you enter, so every person pays an identical share regardless of what they individually ordered. This even-split approach is the simplest and most common way groups handle a shared bill, though it's worth noting it isn't always the fairest method if group members ordered very different amounts — someone who had a $8 salad and someone who had a $40 steak would pay the same amount under an even split. If you need to account for who ordered what, you'd need to calculate each person's actual subtotal separately and apply the tip percentage to each individually, rather than using a single even split.

The per-person amount shown is the mathematically exact division, which will often include cents that don't round to a perfectly convenient number — for example, splitting $61.50 three ways gives exactly $20.50 per person, but splitting $60.00 three ways with an 18% tip might land on an amount like $23.60 per person that isn't as clean. In practice, most groups either round each person's share up slightly to the nearest convenient amount (so the group collectively covers the full bill with a small amount to spare) or one person covers the small remaining difference. This calculator shows you the exact figure; how you round it in practice for cash payments is a small social decision left to your group.

Simple percentages like 10% or 20% are easy to estimate mentally, but odd bill amounts, less common tip percentages like 18% or 22%, or splitting an already-tipped total among an awkward number of people (like 7) quickly become error-prone to calculate by hand, especially at a table with distractions and limited time. A calculator removes any doubt about the exact figure, which is particularly useful for group outings where an incorrect mental calculation could mean someone accidentally over- or under-pays their fair share.

No — every calculation runs entirely inside your browser using plain JavaScript arithmetic. Nothing you enter is transmitted anywhere or stored on any server; the tip, total, and per-person amounts are computed locally on your device the moment you type a number, and nothing about your bill or spending is logged or tracked in any way.

This calculator is built specifically for even splits, where every person in the group pays an identical share of the total bill and tip. For an uneven split based on individual orders, you'd calculate each person's own subtotal separately, then apply your chosen tip percentage to each person's individual subtotal rather than to the group total — this calculator's even-split model doesn't directly support that scenario, since it assumes the total is divided equally rather than proportionally to what each person actually ordered.

No — tipping customs vary enormously by country and even by type of establishment within the same country. Tipping is deeply embedded in US restaurant and service culture, often because service staff wages there are structured around the expectation of tips supplementing a lower base wage. Many other countries either build a service charge directly into the bill, pay service staff a full living wage without tip dependence, or consider unsolicited additional tipping unusual or even mildly awkward in some contexts. Always research or ask about local tipping norms specific to where you are, rather than assuming your home country's customs apply everywhere.
