Calculate your tip
Enter the bill amount and tip percentage. Use the split field to divide the total between multiple people.
How to calculate a tip
The tip formula is: Tip = Bill × (Tip% ÷ 100). The total you pay is: Total = Bill + Tip. When splitting, divide the total by the number of people.
Quick mental math tricks
For 20%: move the decimal one place left to get 10%, then double it. For a $45 bill — 10% is $4.50, so 20% is $9.00. For 15%: find 10% ($4.50), then add half of that ($2.25) to get $6.75. For 25%: find 10%, double it for 20%, then add half of the 10% figure. On $45: $4.50 + $4.50 = $9.00 + $2.25 = $11.25.
Tipping guide by service type
| Service | Typical tip (US) | Note |
|---|---|---|
| Sit-down restaurant | 18–20% | 20%+ for great service |
| Counter / fast casual | 10–15% | Optional but appreciated |
| Takeout / delivery | 10–20% | 15–20% for delivery drivers |
| Bar service | 15–20% or $1–2/drink | Either is acceptable |
| Hotel housekeeping | $2–5/night | Leave daily, not just at checkout |
| Taxi / rideshare | 15–20% | Uber/Lyft app prompts this |
| Hair / beauty services | 15–20% | On service cost, not product add-ons |
| Food delivery app | 15–20% | Tip goes directly to driver |
Do you tip before or after tax?
Most etiquette guides suggest tipping on the pre-tax subtotal, though tipping on the post-tax total is widely accepted. The difference is small — on a $50 bill with 8% tax, 20% pre-tax tip is $10 vs $10.80 on the post-tax total. If your bill already includes sales tax and you want to see exactly how much of your total is tax, the sales tax calculator can back-calculate the pre-tax amount from any tax-inclusive figure.
Splitting the bill unevenly
This calculator splits the total evenly between any number of people. For uneven splits where each person ordered different amounts, calculate each person’s share separately using the same tip percentage. The percentage of a number calculator is handy for quickly finding what X% of any individual subtotal is.
Tipping on large groups
Most US restaurants automatically add an 18–20% service charge (called a gratuity or auto-gratuity) for parties of 6 or more. Check your bill before adding an additional tip — the line items “gratuity” and “tip” are different, and paying both doubles the tip. If the service charge is already included, an extra tip for exceptional service is entirely at your discretion.
International tipping norms
Tipping customs vary significantly by country. In Japan and South Korea, tipping is considered rude and is typically refused. In Australia and most of Europe, tipping is appreciated but not expected — rounding up or leaving 10% for good service is common. In the UK, 10–15% is standard at sit-down restaurants but not at pubs or counter service. In the US and Canada, tipping is effectively part of servers’ expected income given the prevalence of tipped minimum wages, making 18–20% the practical baseline.
Service charges vs tips: what’s the difference?
A service charge is a mandatory fee added by the establishment — it may or may not go directly to staff (policies vary by restaurant and jurisdiction). A tip is a voluntary gratuity paid directly by the customer. In countries with strong labour laws, service charges are more common; in the US, discretionary tipping remains the dominant model. If a menu or bill shows “service included,” no additional tip is expected unless you want to leave one.
Frequently asked questions
Multiply the bill by 0.20. For a $65 bill: $65 × 0.20 = $13 tip. Total is $78. Mental trick: move the decimal left to get 10% ($6.50), then double it ($13).
In the US, 18–20% is now considered standard for sit-down restaurants. For exceptional service, 25% or more is appropriate. For delivery, 15–20% is standard; for counter service, 10–15% is optional but appreciated.
Note each person’s subtotal and apply the same tip percentage individually. This calculator splits the total evenly — for uneven splits, calculate each person’s share separately.
15% of $50 = $7.50 tip. Total bill = $57.50. Quick method: 10% of $50 is $5.00, half of that is $2.50, so 15% = $5.00 + $2.50 = $7.50.
Etiquette guides generally suggest tipping on the pre-tax subtotal, but tipping on the full post-tax total is also widely practised. The difference is small — on a $60 bill with 9% tax, 20% pre-tax tip is $12 vs $13.08 on the post-tax total.
An auto-gratuity is a mandatory service charge added by the restaurant, typically 18–20% for large parties. If auto-gratuity is already included on your bill, no additional tip is required — though you may add one for exceptional service.
