Tip and Bill Split Calculator
Splitting a restaurant check with friends should not need mental math at the table. Enter the bill amount, the tip percentage you want to leave, and the number of people in your group. The calculator adds the tip to the bill, shows the grand total, and divides it evenly so everyone knows exactly what to pay. It also breaks out the tip portion of each share. Every field is editable, so you can tip on the pre-tax subtotal or the total on the check, whatever your group prefers.
Tip and split formula
Tip amount = bill * (tip percentage / 100)
Grand total = bill + tip amount
Each person pays = grand total / number of people
Each person's tip = tip amount / number of people
Increase the tip percentage for better service, or change the number of people as your party grows.
Tipping notes
- In US table-service restaurants, 15% to 20% is common for satisfactory to good service.
- Tipping on the pre-tax subtotal is slightly cheaper than tipping on the taxed total.
- Some venues add an automatic gratuity for large parties; check before adding more.
- Round each share up to the nearest dollar to make settling up easier.
- For uneven splits, apply each person's own portion of the bill separately.
Tip and bill split: frequently asked questions
How is the tip calculated?
The tip equals the bill amount multiplied by the tip percentage divided by 100. For example, a 20% tip on a US$80 bill is 80 times 0.20, which is US$16. The total is the bill plus the tip.
How does the split work?
The grand total (bill plus tip) is divided by the number of people in your group to give each person's share. The calculator also shows the tip portion of each share so everyone can see how much of their payment is the gratuity.
Should I tip on the pre-tax or post-tax amount?
Both approaches are common in the US. Tipping on the pre-tax subtotal is slightly more economical, while many people tip on the total shown on the check for simplicity. Enter whichever bill amount you want to tip on; the calculator applies the percentage to the number you provide.
What is a standard tip percentage in the US?
Tipping is customary in US table-service restaurants, with 15% to 20% common for satisfactory to good service. The exact amount is at your discretion and varies by service quality and region. The percentage field is fully editable.
Can I split unevenly?
This calculator splits evenly across the group. For uneven splits, each person can apply their own share of the bill and add their chosen tip percentage individually, or one person can cover a larger number of shares.
