Tip Calculator

How the math works

The tip amount is the bill times your chosen percentage. The total is the bill plus that tip, and splitting divides the total evenly across however many people are paying — no rounding tricks, just the straight math.

Worked example: a $64 bill at 20% tip, split three ways, comes to a $12.80 tip, $76.80 total, and $25.60 per person. Change any of the three numbers and everything else recalculates immediately.

What's a normal tip?

In the US, 18-20% is the standard range for sit-down table service, with 15% considered the low end for adequate-but-unremarkable service and 25%+ reserved for exceptional service. Delivery drivers are typically tipped 15-20% or a flat $3-5 minimum for small orders. Outside the US, tipping norms vary a lot — many countries with a service charge already built into the bill, or a living-wage service industry, tip little to nothing, so it's worth checking local convention rather than defaulting to US-style rates when traveling.

Splitting a bill unevenly

The even-split option here assumes everyone owes the same share. If people ordered very different amounts, splitting evenly can shortchange whoever had a salad and water — for a genuinely uneven split, add up each person's own items first and apply the tip percentage to their individual subtotal instead.

Tipping on the pre-tax or post-tax total?

Etiquette guidance generally favors tipping on the pre-tax subtotal, not the total after sales tax is added — tax isn't part of what the server actually provided, so tipping on it slightly overpays relative to the service itself. In practice the difference is small (a percentage point or two of the tax rate) and plenty of people tip on the post-tax total anyway purely because it's the number printed largest on the receipt. Enter the pre-tax subtotal here if you want the etiquette-correct figure, or the post-tax total if rounding generously is the goal either way.

Tipping norms beyond restaurants

Tipping conventions vary quite a bit by service type, not just by country — a sit-down restaurant typically expects 18-20%, a hairdresser or barber commonly gets 15-20%, a taxi or rideshare driver often gets 10-15% or rounds up to the next few dollars, and services like furniture delivery or moving crews are usually tipped a flat per-person amount rather than a percentage at all, since there's no clean "bill total" to calculate a percentage of. This calculator's percentage-of-a-bill model fits restaurant and delivery-style tipping best; for a flat-amount tip, it still works fine as a way to check what a given dollar tip works out to as a percentage.
