How to Use This Tip Calculator
This tip calculator shows tip amount, total bill, and per person cost for any bill size and tip percentage. Enter your bill amount, choose a tip percentage using the quick-select buttons (15%, 18%, 20%, 25%) or type a custom percentage, then enter the number of people splitting the bill. The calculator instantly shows the tip amount, total bill, and — when splitting — the per person total and per person tip. Use the Share button to copy a link with your numbers pre-filled.

How to Calculate a Tip
Tip calculation is straightforward multiplication:
- Tip amount = Bill × (Tip % ÷ 100)
- Total bill = Bill + Tip amount
- Per person total = Total bill ÷ Number of people
- Per person tip = Tip amount ÷ Number of people
Example: a $75.00 bill with 20% tip — tip is $15.00, total is $90.00. Split between 3 people: each owes $30.00 total ($25.00 bill share + $5.00 tip each).
Standard Tip Percentages by Situation
US tipping norms vary by service type and quality. Here are current standard ranges:

- Hair salon / barber: 15–20%
- Taxi / rideshare: 15–20%
- Hotel housekeeping: $2–5 per night
- Movers (full day): $20–50 per person
Quick Mental Math Tips
No phone handy? These shortcuts make tip math fast:
- 20% tip: Move the decimal one place left, then double. On $64: 10% = $6.40, doubled = $12.80.
- 15% tip: Find 10%, then add half. On $64: $6.40 + $3.20 = $9.60.
- 18% tip: Find 20% and subtract 10% of that. On $64: $12.80 − $1.28 = $11.52 (round to $11.50).
- 25% tip: Find 10%, then double it, then add half. On $64: $6.40 × 2 = $12.80 + $3.20 = $16.00.
These all work cleanly enough to compute while your waiter runs your card. The calculator above handles the exact math so you can verify your mental estimate.
Should You Tip on Pre-Tax or Post-Tax?
Tipping on the pre-tax subtotal is technically correct and the traditional approach — servers do not earn income from the tax portion of your bill. However, tipping on the total (including tax) is far more common in practice, and the difference is usually $1–3 on a typical restaurant bill. Both are acceptable. Enter whichever number you want to calculate from — this calculator does not enforce either convention.
In states with high sales tax (California at 10.25%, New York City at 8.875%), the difference becomes more noticeable on large bills. On a $200 pre-tax bill in NYC with 8.875% tax, the taxed total is $217.75. A 20% tip on pre-tax = $40; on post-tax = $43.55.
Splitting the Bill Between Groups
Even splits work cleanly when everyone ordered roughly the same amount. When one person ordered a $60 steak and another a $15 salad, equal splitting feels unfair. In that case, calculate each person's share individually and split only the tip equally. A quick approach: each person pays their own subtotal, then the total tip (say 20%) is divided equally.
For very large groups (10+), many restaurants automatically add a mandatory gratuity of 18–20% to the bill. Check your receipt before tipping again — paying double tip is a common mistake.
Tipping Culture and When It Applies
Tipping in the US is not legally required but is socially expected in most service contexts. Many service workers — especially restaurant servers — receive a lower base wage (as low as $2.13/hour federally for tipped employees) and depend on tips for most of their income. If you eat out regularly, factoring a 20% tip into your spending plan with a budget calculator can help you stay on track. In contrast, many other countries build service wages into menu prices and tipping is optional or uncommon.
When traveling internationally, research local norms. In Japan, tipping is considered rude. In Australia and most of Western Europe, tipping 5–10% for good restaurant service is appreciated but not expected. In Canada, 15–18% is standard at sit-down restaurants — similar to the US.
