Split Bill Calculator
Split restaurant bills evenly or by custom individual orders with exact penny accuracy.
How do you split a restaurant bill with tip evenly?
Add the subtotal, sales tax, and tip together, then divide by the number of diners. For a $100.00 bill with a 20% tip ($20.00) split between 4 people, the grand total is $120.00 and each person owes $30.00. When a total cannot divide evenly, leftover cents are assigned one cent at a time so no penny goes missing.
Bill Splitting Formulas
- Equal Share = Floor((Subtotal + Tax + Tip) ÷ People)
- Remainder Cents = (Subtotal + Tax + Tip) mod People
- Custom Share (Person i) = Item Subtotal_i + Tax_i + (Base_i × Tip Rate_i)
Split a Bill Equally vs. Custom Bill Splitting
Equal splitting works best when everyone ordered similarly priced entrees and shared appetizers. When one guest orders steak and cocktails while another orders a salad and water, switch to Custom Split by Person below to assign exact subtotals and even customize individual tip rates.
Handling Remainder Cents Without Shorting the Table
Standard calculators truncate or round down shares—causing 3 people splitting $100.00 to pay $33.33 × 3 = $99.99. Our splitter always accounts for every cent and displays the exact distribution (e.g., 1 person pays $33.34 and 2 pay $33.33) or lets you round up per person.
FAQ
How do I split a bill when everyone ordered different items?
Select the "Custom Split" tab inside the calculator to enter each diner’s name and pre-tax order subtotal. You can apply a shared tax rate and give each person the same or custom tip percentage while verifying the sum matches the original receipt.
What if a group of 6 or more already has automatic gratuity?
Check your printed receipt for an "auto-gratuity" or "service charge" line item. If 18%–20% is already added, set the Tip Percentage to 0% (or only add a small extra percentage if you want to tip more) and split the total evenly.
Can I round each person’s share to a whole dollar?
Yes. Choose "Round Per Person" or "Round Up Per Person" in the rounding selector to simplify Venmo, Zelle, or cash settlements.
How do you split a $120 bill among 4 people?
Divide $120.00 by 4 to get $30.00 per person. If that $120.00 represents a $100.00 meal plus a 20% tip, each person contributes $25.00 toward the meal and $5.00 toward the tip.
