What is the Tip Calculator?

The tip calculator instantly computes how much to tip at a restaurant, hotel, taxi, or any service. Enter your bill amount and tip percentage to see the exact tip, total bill, and per-person split. You can also add the tax rate to calculate the tip on the after-tax amount — the standard US practice. Quick preset buttons (10%, 15%, 18%, 20%, 25%) let you pick a tip level in one tap.

Tip Calculator Formula

Step 1 — Add tax to bill: Tax Amount = Bill × Tax% / 100 Bill with Tax = Bill + Tax Amount Step 2 — Calculate tip (on post-tax amount): Tip Amount = Bill with Tax × Tip% / 100 Step 3 — Compute total and split: Total Bill = Bill with Tax + Tip Amount Tip Per Person = Tip Amount / Number of People Total Per Person = Total Bill / Number of People All amounts rounded to 2 decimal places.

Tip Calculator Example

Example: $85.00 bill, 8% tax, 20% tip, 4 people. Tax Amount = $85.00 × 8% = $6.80 Bill with Tax = $85.00 + $6.80 = $91.80 Tip Amount = $91.80 × 20% = $18.36 Total Bill = $91.80 + $18.36 = $110.16 Tip Per Person = $18.36 ÷ 4 = $4.59 Total Per Person = $110.16 ÷ 4 = $27.54

How to Use the Tip Calculator

  1. 1Enter your bill amount — the subtotal before tax. If the bill already includes tax, set the tax percentage to 0 or leave it blank. Then select a quick tip preset (10%, 15%, 18%, 20%, 25%) or type a custom percentage.
  2. 2Optionally add a tax percentage if you want to tip on the post-tax amount. This is the most common US practice. The calculator shows you both the pre-tax bill and the bill-with-tax so you can see exactly how the tip is calculated.
  3. 3Use the people stepper to set the group size. The calculator instantly shows the tip per person and total per person, making it easy to split the check fairly. Results update in real time as you change any input.

Frequently Asked Questions

How much should I tip at a restaurant?
In the United States, the standard restaurant tip is 15–20% of the pre-tax bill. For good service, 18–20% is typical. For excellent service or fine dining, 20–25% is common. 15% is considered the minimum polite tip. A simple rule: move the decimal one place left (10% of $85 = $8.50) then adjust up or down.
Should I tip on the pre-tax or post-tax amount?
Both are acceptable — it's a matter of personal preference. Tipping on the post-tax amount (which this calculator does by default) results in a slightly higher tip and is the more common practice in the US. Tipping on the pre-tax amount is technically more accurate since tax isn't part of the service. The difference is small: on an $85 bill with 8% tax, tipping 20% on pre-tax = $17 vs. post-tax = $18.36.
How do I split a bill with tip included?
To split a bill evenly: add the tax to the bill, calculate the tip on that amount, then divide the total by the number of people. Formula: Total Per Person = (Bill + Tax + Tip) / Number of People. For example, $85 bill + $6.80 tax + $18.36 tip = $110.16 total ÷ 4 people = $27.54 each. This calculator does all of that automatically.
What is the standard tip for different services?
Tipping norms by service type: Restaurant servers: 18–20%. Bartenders: $1–2 per drink or 15–20% of tab. Food delivery: 15–20% (minimum $3–5). Taxi or rideshare: 15–20%. Hotel housekeeping: $2–5 per night. Valet parking: $2–5. Hair salon: 15–20%. Spa services: 15–20%. Moving services: $20–50 per mover. Always consider the quality of service and local customs.
Is it rude not to tip?
It depends entirely on cultural context. In the United States, tipping is deeply embedded in service culture — many workers in the hospitality industry earn below minimum wage and rely on tips to make a living wage. Not tipping in the US is generally considered rude unless service was genuinely poor. In contrast, tipping in Japan can be seen as offensive or insulting, as it implies the worker's salary isn't adequate. In many European countries, rounding up or leaving small change is customary but a full 20% tip is not expected.
