Quickly calculate tips, split bills, and figure out exactly what everyone owes. Enter your bill amount, choose a tip level based on your service experience, and optionally split between your group — results update in real time.
Pro tip: Always tip on the subtotal (pre-tax amount), not the total. Tax goes to the government, not your server.
How to Use the Tip Calculator
Just start typing your bill amount — results update instantly as you go. Tap a tip preset or hit Custom to drag the slider to any percentage between 2% and 80%. Use the split stepper to divide the total among your group.
Common Tipping Guidelines
- 15% — Standard for acceptable service
- 18–20% — Good to great service
- 25%+ — Exceptional service or large parties
- 10% — Below expectations (consider speaking with a manager)
Tip on the Subtotal, Not the Total
A common question is whether to tip on the pre-tax subtotal or the after-tax total. The standard practice is to tip on the subtotal — the amount before tax is added. Tax goes to the government, not your server, so there is no reason to include it in the tip calculation.
When you get your check, look for the subtotal line (sometimes labeled “Food & Beverage” or just “Subtotal”). That is the number to type into the calculator above. Some restaurants fold tax into the displayed total, so double-check before calculating.
Quick Mental Math
Need to calculate a tip without a calculator? For 20%, move the decimal one place left and double the result. A $45.00 bill becomes $4.50, doubled to $9.00. For 15%, find 10% (move the decimal) and add half of that amount — $4.50 + $2.25 = $6.75.
Splitting the Bill
Use the stepper to set how many people are sharing the check. The “Per Person” amount — the big number at the top of the results — includes each person's portion of both the meal and the tip.
Why Tipping Matters
In many countries, servers rely on tips as a significant portion of their income. A thoughtful tip shows appreciation for good service and helps support the people who make your dining experience enjoyable.
Tipping Norms Around the World
Tipping culture varies dramatically from country to country, and getting it wrong can cause confusion or even offense. In the United States and Canada, tips are a core part of service worker compensation. Federal law allows employers to pay tipped employees as little as $2.13 per hour, with tips expected to make up the difference to minimum wage — meaning that skipping a tip in the US is not just impolite, it can directly harm a worker’s livelihood.
Much of Western Europe takes a different approach. Many restaurants include a service charge in the bill automatically, and when they do not, rounding up to the nearest euro or leaving small change is considered courteous rather than obligatory. In Japan, tipping is generally considered rude — it can imply the staff need charity, or that you are trying to establish a transactional relationship that disrupts the cultural norm of excellent service as a matter of professional pride. Australia pays hospitality workers significantly higher base wages than the US, making tips entirely optional rather than expected. Travelers should always research local customs before arriving to avoid inadvertently insulting their host or undertipping someone who genuinely depends on gratuities.
When Automatic Gratuity Applies
Many restaurants automatically add a service charge — typically 18–20% — for large parties, usually defined as six or more guests. This charge is not optional; it is built into the bill the same way tax is, and the restaurant has the right to collect it regardless of your satisfaction with the service. Look for it listed as a separate line item labeled “Auto Gratuity,” “Service Charge,” or “Gratuity Included” near the bottom of your receipt before adding a tip of your own.
If you have already paid an automatic gratuity and wish to leave additional recognition for exceptional service, that is entirely at your discretion — but it is not expected. The policy exists because large parties create more work and complexity for servers, and they are more likely to result in walkouts or miscalculated splits that leave staff undertipped. If you believe the automatic gratuity was applied incorrectly or the service was genuinely poor, speak with the manager directly rather than simply refusing to pay.
