Total Bill (with tip): $0.00
Each Person Pays: $0.00

How to Split a Bill Fairly

Whether you are dining out with friends or splitting household utilities, calculating exactly how much each person owes can become complicated when tips and service charges are involved. A Bill Splitter Calculator simplifies this process, ensuring no one is overcharged and the service staff receives their fair share.

Calculation Example:
If your total dinner bill is $150.00, you want to leave a 20% tip, and you are splitting the cost among 5 people:
1. Total Tip: $150 × 0.20 = $30.00
2. Total Amount: $150 + $30 = $180.00
3. Per Person: $180 / 5 = $36.00

Standard Tipping Guidelines

While tipping customs vary by country, here are the common standards for service in North America:

  • 15%: Standard service at a casual restaurant.
  • 18%: Good, attentive service.
  • 20%+: Exceptional service or fine dining.
  • 10%: Minimal service or buffet style.

Common Bill Splitting Scenarios

Group Dining: Use this tool to quickly find the per-person total so everyone can contribute via cash or mobile payment apps instantly. It accounts for the pre-tax total if you input the final receipt amount.

Roommate Utilities: If a monthly internet bill is $85.50 and you have 3 roommates, simply set the tip to 0% and the number of people to 3 to find the exact share for each tenant.

Business Lunches: Perfect for determining the total expense to be filed on an expense report while ensuring the tip is calculated accurately against the subtotal.

function calculateSplit() { var bill = parseFloat(document.getElementById("totalBill").value); var tipRate = parseFloat(document.getElementById("tipPercent").value); var people = parseInt(document.getElementById("splitCount").value); var resultDiv = document.getElementById("bill-result"); // Validation if (isNaN(bill) || bill <= 0) { alert("Please enter a valid bill amount."); return; } if (isNaN(tipRate) || tipRate < 0) { tipRate = 0; } if (isNaN(people) || people <= 0) { people = 1; } // Calculations var totalTip = bill * (tipRate / 100); var totalWithTip = bill + totalTip; var perPerson = totalWithTip / people; // Display Results document.getElementById("displayTip").innerText = "$" + totalTip.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2}); document.getElementById("displayTotal").innerText = "$" + totalWithTip.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2}); document.getElementById("displayPerPerson").innerText = "$" + perPerson.toLocaleString(undefined, {minimumFractionDigits: 2, maximumFractionDigits: 2}); resultDiv.style.display = "block"; }
