Bill Split Calculator
Show the math
What Your Result Means
- Tip Amount: The total gratuity for the table, calculated as the bill multiplied by your selected tip percentage.
- Total with Tip: The full amount the group owes — the original bill plus the tip.
- Per Person: Each person's equal share of the total (bill + tip), assuming an even split.
- Per-Person Tip: How much of each person's share goes to the tip alone — useful for seeing what each diner is individually contributing to the gratuity.
How This Calculator Works
You enter the bill total, choose a tip percentage (15%, 18%, 20%, or 25%), and set the number of people. The tool multiplies the bill by the tip percentage to get the tip amount, adds it to the bill for the total, then divides evenly by head count. It assumes an even split with no separate itemized orders, discounts, or additional service charges.
Quick Questions
How much should I tip?
In the U.S., 18–20% is the standard for table service at a sit-down restaurant. 15% is the floor for adequate service, and 25%+ is common for exceptional experiences or large groups. Many restaurants automatically add 18–20% gratuity for parties of 6 or more.
Should I tip on the pre-tax or post-tax amount?
Either is acceptable, but tipping on the pre-tax subtotal is more common in etiquette guides. The difference is usually small — on a $100 bill with 8% tax, tipping 20% pre-tax is $20 vs. $21.60 post-tax.
What about uneven orders?
This calculator splits evenly. If one person ordered significantly more, you may want to split by itemized amounts instead. Some payment apps let each person enter their own items for a fairer breakdown.
Do I tip on alcohol?
Yes — standard practice includes tipping on the full bill including drinks. Some people tip at a slightly lower rate on expensive wine bottles, but the standard 18–20% on the entire check is most common.
