Tip Calculator

Sitting at the end of dinner with the bill, three friends, and the math part of your brain checking out for the day. This calculator handles the only three questions that matter: how much is the bill, what tip do you want to leave (with handy 15/18/20/25 buttons), and how many people are splitting? Returns the tip amount, grand total, and per-person share. No upselling, no convoluted features — just the answer. Works for restaurants, bars, takeout, delivery, salons, and anywhere else tipping is part of the transaction.

Enter the bill total.

US tipping conventions in 2025

Tipping in the US has crept upward over the past decade. Current expectations:

  • Sit-down restaurants: 18-22% standard. 25% for exceptional service. 15% only if service was actively bad.
  • Bars: $1-2 per drink, or 18-20% of the tab for a multi-drink night.
  • Takeout: 0-10%. Many places now prompt for tips on takeout; convention is no tip or up to 10% for orders that involve real work (large catering pickup, etc.).
  • Food delivery (Uber Eats, DoorDash): 15-20% or $3-5 minimum, especially for shorter orders where percentage works out to almost nothing.
  • Hairdresser / barber: 15-20%.
  • Spa, massage: 18-20%.
  • Hotel housekeeping: $3-5 per night, left on the pillow.
  • Hotel bellhop: $2-3 per bag carried.
  • Valet: $2-5 when the car comes back.
  • Coffee shop counter: $0-1 per drink. Optional; appreciated.
  • Cafeterias and fast-casual counter service: not expected. Tip-screen guilt notwithstanding.

Quick math tricks for tip without a calculator

  • 10%: shift decimal one place left. $47.50 → $4.75.
  • 20%: 10% times 2. $4.75 → $9.50.
  • 15%: 10% + half of 10%. $4.75 + $2.37 = $7.12.
  • 18%: 20% minus a bit, or 15% + 3% (10% + half + a couple bucks). Roughly $8.55 on $47.50.
  • 25%: 20% + a quarter of 20%. $9.50 + $2.37 = $11.87.

For most casual purposes, rounding up to the nearest dollar after applying the percentage is fine — the difference between $8.55 and $9 tip is negligible to the server.

How to use this calculator

  1. Bill total ($): enter the pre-tax subtotal (or final total — see FAQ).
  2. Split between # people: how many ways to divide.
  3. Tip %: drag the slider or click 15/18/20/25 quick buttons.
  4. Output: per-person share, tip amount, and grand total.

Common scenarios

$80 dinner for 2, 20% tip. Tip $16. Grand total $96. Per person $48.

$240 dinner for 5, 18% tip. Tip $43.20. Grand total $283.20. Per person $56.64. Round to $57 each so the host doesn't have to chase quarters.

Date-night drinks, $58 bar tab, 20% tip. $11.60 tip, $69.60 total. Round to $70.

FAQ

Tip on subtotal or total (with tax)? +
Traditionally on subtotal (pre-tax). Tipping on the post-tax total isn't wrong — it makes the tip slightly larger. The difference at 8% tax is about 1.5% more on the tip. Both conventions are common; pick the one you're comfortable with.
What about automatic gratuity on big groups? +
Many restaurants add 18-20% automatic gratuity ("auto-grat") to parties of 6 or 8+. Always check the bill before tipping again. If auto-grat is included, you can add a small additional tip for exceptional service (5-10% on top) but you're not obligated.
Should I tip on alcohol? +
Yes — your server brought the drinks, opened the wine, kept tabs. Standard percentage applies to the whole bill including alcohol. Bar-only tabs (sitting at the bar): tip the bartender 15-20% or $1-2/drink.
What if service was bad? +
15% is the floor for any service that isn't actively terrible. Below 15% sends a clear message that the food/service failed. For genuinely bad service, talk to a manager rather than punishing the server (who often isn't the source of the problem).
What about tip-pooling — does my tip even reach the server? +
Most US restaurants pool tips and split among front-of-house staff (servers, bussers, runners, host). Some include kitchen. Cash tips sometimes go directly to the server; card tips always pool. Either way, the server you interacted with benefits even if not 100% of the dollar reaches them.
Do I tip on coupons or discounted bills? +
Yes — tip on the pre-discount amount. The server still did the work; the discount comes from the restaurant's margin, not the server's compensation.
What about tipping internationally? +
Varies wildly. UK: 10-12% if service charge not included. Europe (most): 5-10% or round up. Japan: NO tipping; can be culturally insulting. Australia/New Zealand: minimal, 10% for exceptional service. Always check local custom — over-tipping in some countries comes across as obnoxious.
What's a good tip on small bills? +
Below $10-15, the percentage gets awkwardly small. Round to a minimum $2-3 tip for any sit-down meal, even if that's 30% on a $7 breakfast. Servers depend on tip aggregate; tiny percentages on small bills hurt more than they should.
