Frequently Asked Questions
How do you calculate a tip?
Multiply the bill amount by the tip percentage. For a $50 bill with an 18% tip: $50 × 0.18 = $9 tip, for a total of $59. To split between 4 people: $59 ÷ 4 = $14.75 each. This calculator does all that instantly as you type.
What is a standard tip percentage in the US?
In the United States, 15–20% is standard for restaurant service. 15% is considered acceptable for adequate service, 18% is good, 20% is common for great service, and 25%+ is for exceptional service or when you want to be especially generous. For takeout, counter service, or food delivery, 10–15% is typical.
Is tipping customary in all countries?
No. Tipping customs vary widely by country. In the US, Canada, and some Middle Eastern countries, tipping is expected. In Japan, South Korea, and much of Southeast Asia (including Vietnam), tipping is not customary and may even be considered rude. In Europe, rounding up or leaving small change is common but large tips are not expected. Always research local customs when traveling.
Should I tip on the pre-tax or post-tax amount?
There's no strict rule, but most people tip on the pre-tax subtotal. Some argue tipping on the post-tax total is fairer to servers since the tax varies by location. The difference is usually small — on a $50 bill with 10% tax, you'd tip on $50 vs $55, which is a $1 difference at 20%.
What is the easiest way to calculate a 20% tip in your head?
Move the decimal one place to the left to get 10%, then double it. For a $47.50 bill: 10% is $4.75, doubled = $9.50 tip. For 15%, find 10% and add half of 10%. For a $47.50 bill: $4.75 + $2.38 = $7.13.
How do rounding options work?
"Exact" shows the precise calculation. "Round tip up" rounds the tip to the next whole dollar (or 1,000 VND). "Round total up" rounds the entire bill total up. "Round per-person up" rounds each person's share up to a clean number — this is the most convenient for splitting, as everyone pays the same rounded amount.
