Tip Calculator, Split Bills & Calculate Gratuity by Service

Calculate tips and split bills evenly among any number of people. Find gratuity by service quality level and per-person share.

According to the U.S. Internal Revenue Service and the National Institute of Standards and Technology, more than 1,000 published rate, threshold, and conversion reference values update annually across tax, mortgage, and engineering domains that CalcMesh formulas trace to. The CalcMesh registry listed 53 calculators across 9 categories as of August 2026. See our methodology for derivation standards and refresh cadence.

How CalcMesh calculates a tip

A tip is a percentage of the pre-tax bill, optionally split across a party. In the United States, 15% to 20% is the customary range for table service, so we offer those as quick presets.

We compute the tip, total and per-person share from your bill and rate; the rounding options we use are documented in our methodology.

Tipping Etiquette Guide

Tipping customs vary by service type. Here are the standard percentages for common situations in the United States:

Restaurants

  • Sit-down dining: 15-20% of the pre-tax bill
  • Buffets: 10% is common
  • Takeout: Not expected, but 10% is appreciated

Delivery & Rides

  • Food delivery: 15-20%, minimum $3-5
  • Taxi/rideshare: 15-20% of the fare
  • Grocery delivery: 10-15%

Personal Services

  • Hairstylist/barber: 15-20%
  • Spa services: 15-20%
  • Tattoo artist: 15-25%

Hotels

  • Housekeeping: $2-5 per night
  • Bellhop: $1-2 per bag
  • Concierge: $5-20 for special assistance
  • Valet: $2-5 when your car is returned

After you split the bill

What to do with the numbers

  • Match the tip rate to the service type from the etiquette guide above - 15-20% for sit-down dining is not the right default for a buffet (10%) or takeout (10% appreciated, not expected).
  • For group meals, use the per-person split output directly rather than mentally dividing the total - rounding errors add up fast when everyone does their own math at the table.
  • Check whether the bill already includes an automatic gratuity (common for large parties) before adding another tip on top of the pre-tax amount.
  • For delivery, remember the minimum: even a small order usually warrants at least $3-5, calculate the percentage but do not go below that floor.

Methodology & Assumptions

This ratio tool applies exact proportion identities to your operands. Percent change, share-of-total, and split modes differ only in labelling; the arithmetic path is deterministic.

How this ratio node runs

Percentage and ratio tools apply exact proportion identities. Change, of-a-number, and split modes share the same arithmetic family with different labelled inputs. Published domain formulas govern the identities; when an agency updates rates or thresholds we refresh defaults and the page lastmod.

Frequently Asked Questions

How much should I tip at a restaurant?
In the United States, 15-20% is standard for sit-down restaurants. For exceptional service, 25% or more is appropriate. Some restaurants include a gratuity for larger parties (usually 18%), so check your bill before adding extra.
Is tipping mandatory in the U.S.?
Tipping is not legally required, but it is a strong social expectation in the United States. Many service workers rely on tips as a significant portion of their income, as their base hourly wage is often below the standard minimum wage.
How do I split a bill fairly among friends?
The simplest method is to divide the total (including tip) equally by the number of people. If people ordered items with very different prices, consider splitting based on what each person ordered, then adding an equal share of the tip on top.
Should I tip on the pre-tax or post-tax amount?
Etiquette experts generally recommend tipping on the pre-tax subtotal. However, tipping on the total after tax is common and simpler. The difference is usually small, so either approach is acceptable.
