Formula
Tip = Bill Amount × Tip% ÷ 100
Multiply the bill amount by the tip percentage and divide by 100. Add to the original bill for the total. Divide by the number of people for an equal split. Note: tipping norms vary by country — this calculator uses US conventions.

Tipping etiquette in the US
Tipping norms have evolved significantly. In restaurants, 18–20% is now considered standard for good service, up from 15% a decade ago. Many service workers rely heavily on tips to reach livable wages, as base pay is often the tipped minimum wage ($2.13/hour federal).
For services beyond restaurants: rideshare (15–20%), food delivery (15–20% plus it's more impactful since drivers cover fuel), hotel housekeeping ($3–5/night), bartenders ($1–2/drink or 20% for tab).
Should you tip on the pre-tax or post-tax amount?
There's no universal rule, but tipping on the pre-tax amount is more common and technically more accurate — the server didn't provide the government tax service. In practice, the difference is small: on a $100 bill with 10% tax, tipping 20% on pre-tax is $20 vs. $22 on post-tax.
When in doubt, tip on the total (post-tax) amount — it's simpler and gives slightly more to your server.
Tips & Insights
Quick 20% mental math
Move the decimal left one place to get 10%, then double it for 20%. For a $68 bill: 10% = $6.80, 20% = $13.60. No calculator needed.
Consider the full context
Tip based on service quality and difficulty, not just percentage. A $5 coffee at a table-service café deserves more consideration than 20% of $5 = $1 tip for full table service.
Worked Examples
Dinner for four
Tip: $37.20. Total: $223.20. Each person owes $55.80. Round up to $56/person for a clean split.

Frequently Asked Questions
How much should I tip?
Standard tipping in the US: 18–20% for restaurants, 15–20% for delivery, $1–2 per drink at bars, $3–5/night for hotel housekeeping, 15–20% for rideshare.
Is it okay to not tip?
In the US, while tipping isn't legally required, service workers often earn below minimum wage with the expectation of tips. Not tipping for adequate service is generally considered poor etiquette.
What if service was bad?
If service was genuinely poor (and not due to kitchen issues), tipping 10% communicates dissatisfaction while still leaving something. If you have a serious complaint, speak to a manager.
