Bill Split
Split a bill evenly between people after adding tip or tax.
About Bill Split
Each person's share is the grand total (bill plus tax plus tip) divided by the number of diners, assuming an even split. Basing the tip on the pre-tax bill rather than the post-tax total is the common convention and keeps the gratuity predictable.
