What is the Tip Calculator?
A tip calculator computes the tip amount on a bill and divides the total (bill + tip) among diners. Cal44 supports any tip percentage and any group size, returning the per-person share rounded to two decimals.
How to use the Tip Calculator
- Enter the pre-tip bill amount.
- Enter or select the tip percentage (10%, 15%, 18%, 20%, or custom).
- Enter the number of people splitting the bill.
- Read the tip amount, total bill and per-person share.
Formula
Tip = Bill × (TipPercent ÷ 100) Total = Bill + Tip PerPerson = Total ÷ People
Bill = pre-tip amount · TipPercent = tip percentage · People = number of diners
Worked example
Bill is $84.50, tip 18%, party of 4. Tip = 84.50 × 0.18 = $15.21. Total = $99.71. Per person = $24.93.
