Work out a tip two ways: a table of common percentages for a single bill, or a shared-bill split that also shows the tip and total per person. In the U.S., 15% of the before-tax price is the usual starting point.
Formula
Tip is a percentage of the bill. Each displayed money value is rounded to the nearest cent from the raw (unrounded) figure — the total is not the rounded tip added back to the price.
raw tip = price × (rate ÷ 100)
tip = round to cents(raw tip)
total = round to cents(price + raw tip)
tip per person = round to cents(raw tip ÷ people)
total per person = round to cents((price + raw tip) ÷ people)
Typical tips in the United States and Canada
Rates are customary, not required. Large parties may have gratuity added automatically; hotel room service is often already included.
| Service | Typical tip |
|---|---|
| Restaurants, bartenders | 15–20% |
| Food delivery | 15–20%, more for long trips |
| Hotel room service | Often included; otherwise 15–20% |
| Hotel housekeeping | Not expected; $1–$2 per person per night |
| Auto mechanic | Not expected; a few dollars for extra help |
| Movers, furniture or appliance delivery | Not expected; $5, $10, or $20 each |
| Plumber, electrician, cleaner, other home services | Not expected; $5, $10, or $20 each |
| Hair, barber, nail salon | 10–20% |
| Massage | 10–20% |
| Taxi or limo | 15–20% |
| Shuttle driver, parking attendant | $1–$3 |
| Tour guide | $1–$5 depending on length |
Examples
15% on a $55 bill
A $55 bill at 15% is a $8.25 tip and a $63.25 total. At 20% the tip is $11.00 and the total is $66.00.
Split $123.45 at 18% among four people
The tip is $22.22 and the total is $145.67. Each person pays $5.56 of tip and $36.42 overall.
Half-cent split on $66.70
15% of $66.70 is a raw tip of $10.005, which rounds to $10.01. Split two ways from the unrounded figures: $5.00 tip each and $38.35 each.
