What is a Split Bill Calculator?
A Split Bill Calculator is a precise tool that helps you divide a shared bill fairly between friends, family, or colleagues. It considers the bill subtotal, item-level sharing, tax, tip, and service or delivery fees so nobody overpays or underpays.
This calculator works for:
- Restaurant bills - Different meals, shared appetizers, drinks, and fair tip allocation.
- Delivery orders - Splitting food, fees, and driver tip among multiple people.
- Group events - Birthdays, team lunches, or celebrations where people order unevenly.
- Travel meals - Road trips and vacations where multiple travelers share costs.

How the Split Bill Calculator Works
The calculator uses proportional allocation so that each person pays based on what they actually consumed.
You can choose whether the tip is calculated on the subtotal only or on subtotal plus tax, and whether per-person amounts are rounded normally or always rounded up.
Key Concepts Explained
Proportional Fairness
People who ordered more pay a larger share of tax, tip, and fees, avoiding unfair equal splits.
Itemized Sharing
Shared dishes are divided only among selected people, so everyone sees a transparent breakdown.

Frequently Asked Questions (FAQ)
Q: What does the Split Bill Calculator do?
A: It divides a shared bill fairly by allocating each person's items plus their proportional share of tax, tip, and any fees so totals match exactly.
Q: How does it handle tax, tip, and service fees?
A: Tax, tip, and fees are distributed based on each person's pre-tax share, ensuring those who order more pay more of the shared charges.
Q: Can I split only certain items among specific people?
A: Yes. Use the itemized section to assign items to a subset of people while leaving others shared or general.
Q: How are rounding differences handled?
A: The tool rounds to cents and, if needed, applies a tiny adjustment (usually one cent) so the sum of per-person amounts equals the grand total.
Q: What if I do not use the itemized section?
A: The calculator defaults to an equal split of subtotal, tax, tip, and fees across all people.
