Tip Calculator: Free Bill Splitter & Gratuity Tool
Calculate restaurant tips, bar gratuities, and split bills evenly among friends in real time. Features standard tipping presets (15%, 18%, 20%), custom percentages, cash round-up options, and exact cost-per-person shares.
To calculate a tip, multiply the bill amount by the tip percentage as a decimal: Tip Amount = Bill × (Tip% / 100). Add the tip to the original bill to find the total: Total = Bill + Tip. To split among a group, divide both the tip and total by the number of people: Share per Person = Total / People.
Standard Tipping Etiquette Across the Service Industry
In the United States and Canada, tipping is a social and economic norm because tipped employees are subject to a lower statutory sub-minimum wage, relying on gratuities as a major portion of their earnings.
| Service Profession | Standard Tipping Benchmark | Customary Rule of Thumb |
|---|---|---|
| Sit-Down Dining Servers | 18% – 20%+ | 15% for fair service; 18%–20% for attentive dining; 25% for exceptional banquets. |
| Bartenders | $1 – $2 per drink or 20% | $1 for draft beer/wine; $2 for complex cocktails; 20% on open bar tabs. |
| Food Delivery (DoorDash, UberEats) | 15% – 20% ($3 – $5 min) | Minimum $3–$5 for short distances; 20%+ during blizzards, rain, or rush hours. |
| Rideshare & Taxi (Uber, Lyft) | 10% – 20% ($2 – $5 min) | $2–$3 for standard short trips; 20% for airport luggage handling and clean rides. |
| Hair Stylists & Barbers | 15% – 20% | Standard 20% for cuts and coloring; cash preferred directly to stylist. |
| Hotel Housekeeping | $3 – $5 per night | Leave cash daily in marked envelope, as cleaning staff rotates daily. |

Pre-Tax vs Post-Tax Tipping: The Mathematical Proof
According to formal etiquette standards (such as the Emily Post Institute), tips should be calculated strictly on the pre-tax food and beverage subtotal:
Taxes represent municipal revenue, not hospitality service. Notice the difference on a $100 dinner bill with 10% sales tax ($110 total):
- Pre-Tax 20% Tip: $100 × 0.20 = $20.00 Tip → Total Paid: $130.00
- Post-Tax 20% Tip: $110 × 0.20 = $22.00 Tip → Total Paid: $132.00 ($2.00 extra paid on tax)
While digital Point-of-Sale (POS) touchscreens often compute default percentages on the higher post-tax total, tipping on the pre-tax subtotal is mathematically and culturally correct.
How to Split a Restaurant Bill Fairly When Orders Are Unequal
Splitting a bill evenly per person works well when everyone orders similar meals. However, when orders diverge significantly, follow these fair group dining practices:
- Separate Alcohol from Food: Alcohol often accounts for 40%–60% of a dinner tab. Non-drinkers should not be forced to subsidize expensive cocktails or wine bottles. Calculate the drink total separately among the drinkers.
- The Proportional Tip Rule: Each person calculates their individual food/drink total, adds local sales tax, and multiplies their own subtotal by 18%–20%.
- Use Digital Split Pay: Have one person pay the total check with a rewards credit card, while group members immediately reimburse their exact share via peer-to-peer payment apps (Venmo, Zelle, CashApp).

Frequently Asked Questions
How much should you tip for good service at a restaurant?
In the United States, 18% to 20% of the pre-tax food and drink subtotal is the standard tip for good to excellent sit-down table service. For buffet service, 10% is customary, while bartenders typically receive $1 to $2 per drink or 20% of the bar tab.
How do you split a restaurant bill with uneven orders?
If orders are roughly equal, splitting the total bill evenly across the group is easiest. If one person ordered expensive alcohol or steak, calculate their item cost plus 18%–20% tip separately, and split the remaining balance among the other diners.
What is an automatic gratuity?
An automatic gratuity (service charge) is a mandatory tip—typically 18% or 20%—automatically added by restaurants to bills for large parties of 6 or more people. Always inspect your itemized bill before tipping to avoid double-tipping.
How much should you tip delivery drivers?
Food delivery drivers (DoorDash, UberEats, pizza delivery) should receive a minimum tip of $3 to $5, or 15% to 20% of the order total, whichever is greater, especially during severe weather or long-distance deliveries.
Is my bill calculation saved or tracked on a server?
No. All calculations run 100% locally inside your smartphone or computer browser memory using JavaScript. No dining amounts, split shares, or restaurant bill data are transmitted over an HTTP network or saved in an external database.
