About Tip Calculator
The Tip Calculator computes the tip amount, total bill, per-person total, and tip per person based on the bill amount, tip percentage, and number of diners. Enter the pre-tip subtotal, select or type a tip percentage (common presets: 10%, 15%, 18%, 20%, 25%), and enter the number of people splitting the bill. The calculator instantly shows all four values: tip amount, total (bill + tip), per-person total, and tip per person.
Tipping conventions vary by country and service type. In the United States, 15–20% is the standard range for restaurant service, with 18–20% increasingly common for good service. Tip calculator tools are used at restaurants, bars, hotels, taxis, salons, and any service context where a gratuity is expected. The per-person split feature is particularly useful for group dining when everyone wants to pay an equal share including their portion of the tip.
The calculator processes all math on the client side in real time. The tip formula is: tip amount = bill × (tip% / 100); total = bill + tip amount; per person total = total / people; tip per person = tip amount / people. Results are rounded to the nearest whole number for currency convenience. The per-person total is highlighted to draw attention to the most-requested result when splitting a group bill.

Frequently Asked Questions
How do I calculate a 20% tip on a $85 bill?
Multiply the bill by 0.20: $85 × 0.20 = $17.00 tip. Total = $85 + $17 = $102. Enter 85 in the amount field, select 20%, leave people as 1, and the calculator shows tip amount $17 and total $102 instantly.
How do I split a bill equally with tip included?
Enter the bill amount, select the tip percentage, and enter the number of people. The "Per Person" result automatically divides (bill + tip) by the number of people. For example, a $120 bill with 18% tip = $141.60 total, split between 4 people = $35.40 per person.
What is the standard tip percentage in the US?
15% is considered the minimum for acceptable service in the United States. 18–20% is standard for good service at sit-down restaurants. 20–25% is for excellent service or when acknowledging extra effort. For takeout, 10–15% is common but optional. For hotel housekeeping, $2–5 per night is standard practice.
Should I tip on the pre-tax or post-tax amount?
Traditionally, tipping on the pre-tax subtotal is the standard recommendation in the US, as the server does not provide the tax service. However, many people find it simpler to tip on the full post-tax total, and the difference is usually small. Enter whichever amount you prefer — the calculator does not know or care which figure you use.
How do I calculate tip without a calculator?
For 20%: move the decimal point one place left (10%), then double it. For a $47 bill, 10% = $4.70, doubled = $9.40 for a 20% tip. For 15%: calculate 10%, then add half of that. $4.70 + $2.35 = $7.05 for 15%. For 18%: use 20% and subtract 2% (move decimal two places, divide by 5).
What is the tip for delivery drivers and food delivery apps?
For restaurant delivery, 15–20% of the order total is standard, with a minimum of $3–5 for small orders to account for the driver's time and fuel. For food delivery apps (DoorDash, Uber Eats, etc.), 15–20% is recommended. Drivers see tips before accepting orders, so higher tips often result in faster service, especially during peak times.
How do I tip at a hotel or resort?
Bellhop/porter: $1–2 per bag. Concierge: $5–25 depending on service complexity. Housekeeping: $2–5 per night, left daily with a note. Room service: check if gratuity is already included (look for "service charge" on the bill). Spa services: 15–20% is standard. Valet parking: $2–5 when your car is retrieved.
Do I tip on drinks separately at a bar?
The common practice at a bar in the US is $1–2 per drink for simple orders (beer, basic cocktails) or 15–20% of the tab at the end of the night if you ran a tab. At a full-service restaurant, drinks are typically included in the overall bill for tipping purposes. For bottle service at nightclubs, 15–20% of the bottle price is standard.
