What Is a Tip Calculator?
A tip calculator is a free online tool that instantly works out how much gratuity to leave on a restaurant, bar, salon, taxi, or delivery bill — and what the grand total comes to once the tip is added. Instead of doing mental math at the table, you enter the bill amount, choose a tip percentage, and (optionally) the number of people splitting the check. The calculator returns the tip amount, the total bill, and the exact amount each person owes, rounded cleanly so nobody overpays or underpays.
Tipping etiquette varies by service and by country, which is exactly why a quick, accurate gratuity calculator removes the guesswork. Whether you are rewarding excellent service with 25% or sticking to a standard 18%, this tool keeps the math honest and the split fair.
How to Use This Tip Calculator
- Enter the bill amount — the pre-tip total from your check (use the amount before or after sales tax, depending on your preference).
- Choose a tip percentage — tap a common preset (15%, 18%, 20%, 25%) or type a custom value.
- Enter the number of people — leave it at 1 for a solo bill, or set it higher to split the bill evenly.
- Read your results — the tip amount, total with tip, and per-person share update instantly.
How Tip Is Calculated
The formula is simple: Tip = Bill × (Tip % ÷ 100) and Total = Bill + Tip. To split, divide the total by the number of people. For example, on a $80 bill at 20% with 4 people: the tip is $16, the total is $96, and each person pays $24.
Standard Tipping Percentages by Service
| Service | Customary Tip (US) |
|---|---|
| Sit-down restaurant | 15%–20% (25% for exceptional service) |
| Bartender | $1–$2 per drink, or 15%–20% of the tab |
| Food delivery | 10%–15% (minimum $3–$5) |
| Taxi / rideshare | 10%–15% |
| Hairdresser / barber | 15%–20% |
| Hotel housekeeping | $2–$5 per night |
Tip on Pre-Tax vs Post-Tax Total
Technically, gratuity is calculated on the pre-tax subtotal, since the tax portion is not part of the service. In practice, many people tip on the post-tax total for simplicity — the difference is usually only a few cents to a dollar. This calculator lets you enter whichever figure you prefer.
Tipping Around the World
Tipping norms differ dramatically by country. In the United States and Canada, tipping 15%–20% is expected because service wages are low. In much of Europe a service charge is often included, and an extra 5%–10% is a generous bonus. In Japan and South Korea, tipping is not customary and can even cause confusion. When traveling, check local etiquette before applying a US-style 20% tip.
Frequently Asked Questions
How do I calculate a 20% tip?
Multiply the bill amount by 0.20. For a $50 bill, a 20% tip is $10, making the total $60. A quick shortcut: take 10% of the bill (move the decimal one place left) and double it.
What is a normal tip at a restaurant?
In the United States, 15%–20% of the pre-tax bill is standard for sit-down restaurants, with 18% being the most common default and 20%–25% reserved for great service.
How do I split a bill between friends?
Enter the total bill and the number of people. The calculator divides the bill plus tip evenly, showing the exact amount each person owes.
Should I tip on tax?
Customarily, tip is based on the pre-tax subtotal. Tipping on the post-tax total is also common and only adds a small amount — both are perfectly acceptable.
Is this tip calculator free?
Yes — it is completely free, requires no signup, and works on any phone, tablet, or computer.
