Work out bill split with tip instantly with clear inputs, formula shown and shareable results.
The tip is a percentage of the pre-tip bill, added before dividing. Rounding each share up to a convenient amount avoids awkward change and usually leaves a little extra on the table, which is shown separately so nobody is short.
Bill split
total = bill x (1 + tip%); each share = total / people, rounded up to the chosen increment
Convention varies. Tipping on the pre-tax subtotal is common and defensible; tipping on the total is simply more generous.
Split by item instead. An even split is only fair when orders are broadly comparable, otherwise use itemised shares.
