Practical bill-splitting guidance

Equal or itemized?

Use an equal split when everyone agrees to divide the whole check. Use an itemized split when orders differ and each diner should pay for assigned items.

Shared dishes

Assign a shared dish to everyone who ate it. Its line total is divided equally among only those diners.

Proportional tax and tip

In itemized mode, discounts, tax, fees, and tip follow each person's share instead of being divided equally.

Included gratuity

Enter mandatory or included gratuity as a service charge. Set tip to 0% unless the group wants to leave an additional tip.

Tip before or after tax?

Choose the basis that matches your preference or local practice. The calculator always displays the tip base so the choice is transparent.

How the calculation works

The calculator uses this order: receipt items or bill subtotal → discount → tax → service and delivery fees → tip → split → optional share rounding.

Subtotal
sum(item price × quantity), or entered bill subtotal
Taxable subtotal
subtotal − discount
Tax
taxable subtotal × tax rate, or fixed receipt tax
Tip base
taxable subtotal, plus tax when “After tax” is selected
Tip
tip base × tip rate, or fixed tip amount
Grand total
taxable subtotal + tax + service charge + delivery fee + tip
Equal share
grand total ÷ number of people
Shared item
item line total ÷ number of selected diners
Itemized add-ons
charge × (person's applicable subtotal ÷ group applicable subtotal)

Calculations keep full precision until display. “Nearest currency cent” rounds every share to the currency's normal minor unit; “whole currency unit” rounds every share upward. If rounded shares do not equal the receipt total, the result states the difference. The optional adjustment changes the tip by that exact difference so all displayed shares reconcile.

Worked bill-splitting scenarios

1. Equal split

  1. Subtotal: $120.00
  2. Tax: 10% × $120 = $12.00
  3. Tip: 20% pre-tax × $120 = $24.00
  4. Total: $120 + $12 + $24 = $156.00
  5. Four diners: $156 ÷ 4 = $39.00 each

2. Tax and after-tax tip

  1. Subtotal: $100.00
  2. Tax: 8% × $100 = $8.00
  3. After-tax tip base: $100 + $8 = $108.00
  4. Tip: 18% × $108 = $19.44
  5. Total: $127.44; three diners pay $42.48 each

3. Uneven itemized split

  1. Ava's items: $30; Ben's items: $20
  2. Tax: 10% gives Ava $3 and Ben $2
  3. Pre-tax tip: 20% gives Ava $6 and Ben $4
  4. Ava pays $39.00; Ben pays $26.00

4. Shared appetizer

  1. $12 appetizer shared by Ava, Ben, and Chen: $4 each
  2. Entrées: Ava $18, Ben $22, Chen $20
  3. Item subtotals: $22, $26, and $24
  4. With 10% tax and 15% pre-tax tip: $27.50, $32.50, and $30.00

Frequently asked questions

How do I split a bill when people ordered different amounts?

Use Itemized split. Add each person and receipt item, then select everyone responsible for each item. The calculator gives every diner an item subtotal and allocates discount, tax, fees, and tip in proportion to what they ordered.

How are shared dishes divided?

Select every person who shared the dish. That item's price multiplied by its quantity is divided equally among only those selected diners.

Should I tip before or after tax?

Practices vary. Choose Pre-tax subtotal to calculate tip after the discount but before tax, or choose After tax to include tax in the tip base. The result shows the exact tip base used.

How do I handle included gratuity?

Enter an included gratuity as a fixed service charge and set the optional tip to 0% unless you want to add an extra tip. This keeps the receipt charge separate and visible.

How are tax and tip allocated in an itemized split?

Each diner receives discount, tax, service fees, delivery fees, and tip proportionally according to their assigned item subtotal and applicable tip base. This avoids charging a light spender the same add-ons as a heavy spender.

What happens to rounding differences?

Without tip adjustment, the calculator shows the difference between the displayed rounded shares and the receipt total, which the organizer must settle. Turn on Adjust tip to match rounded shares to add or subtract that difference from the tip so the shares reconcile exactly.
