Reconcile pretax bill, tax, service charge and discretionary tip with exact minor-unit equal or custom-weight bill splits.
01 / PURPOSE-SPECIFIC INPUTS
02 / RESULT & INTERACTIVE INSPECTION
Tipping is discretionary and customs vary. The service-charge input is an additional amount not already included in the pretax bill. This tool uses two-decimal currency arithmetic; zero-/three-decimal currency conventions are not modeled.
Person 1 pays $30.00. All 4 payments sum exactly to $120.00.
| Person | Relative weight | Payment |
|---|---|---|
| 1 | 1 | $30.00 |
| 2 | 1 | $30.00 |
| 3 | 1 | $30.00 |
| 4 | 1 | $30.00 |

Enter the pretax bill excluding both tax and the additional service charge. Tax, service and discretionary tip remain separate components and are added once to form the grand total.
Reconcile pretax bill, tax, service charge and discretionary tip with exact minor-unit equal or custom-weight bill splits. Inspect real calculated values through accessible visual controls and review the worked assumptions.

Pretax mode applies the entered percentage to the bill alone. After-tax mode applies it to bill plus tax. Both exclude service charge from the discretionary-tip basis; service is not silently duplicated or credited as a discretionary tip.
Nonnegative relative weights need not sum to one hundred. The calculator floors exact minor-unit shares, then assigns leftover minor units to the largest fractional remainders, using input order for ties. All final payments sum exactly to the total.
The discretionary percentage contributes zero, while tax and additional service charge remain separate. A chosen whole-unit round-up can still add an explicitly labeled discretionary amount; zero-total bills receive no invented percentage diagram.
The initial percentage tip rounds half up to a minor unit. Rounding the grand total, or equal per-person payments, upward to whole currency units adds the difference to discretionary tip rather than changing tax or service.
No. It uses exact two-decimal minor-unit arithmetic and a user-entered display label. Zero- or three-decimal currency conventions and foreign-exchange processing are outside its scope.
