What This Calculator Does
This tip calculator computes tip amount and total bill based on the bill amount and desired tip percentage. It includes bill splitting for groups, with preset buttons for common tip percentages and a custom option.
The Formula
The tip is a straight percentage of the pre-tax bill amount. For splitting, the total (bill plus tip) is divided equally among all diners.
Step-by-Step Example
Enter bill amount
Input the pre-tax bill total. Example: $85.50.
Select tip percentage
Choose a preset (10%, 15%, 18%, 20%, 25%) or enter a custom percentage.
Split the bill
If dining with others, enter the number of people to split between.

Common Mistakes to Avoid
Tipping on the post-tax amount instead of the pre-tax subtotal (though tipping on the total is also acceptable).
Using a lower tip percentage for large bills. The same service level deserves the same percentage regardless of bill size.
Forgetting that some restaurants include automatic gratuity for large groups (typically 18-20%).
