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.
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.
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)
Bill and policy limits
The calculator applies the entered percentage to the selected bill base and divides the result arithmetically. Local tax treatment, service charges, automatic gratuities, pooled tips, card fees, and workplace rules are not inferred. Check the receipt before adding a tip, especially when a service charge is already included.
