How to use this calculator

  1. Enter the subtotal before discount, service and tax.
  2. Add the discount, service charge and tax percentages from the bill.
  3. Enter the number of people.
  4. If you had extra items, enter their value to see your own share.

The formula

After discount = Subtotal × (1 − Discount%). Service = After discount × Service%. Tax = (After discount + Service) × Tax%. Grand total = After discount + Service + Tax. Equal share = Grand total ÷ People.

Worked example

A ₹3,200 subtotal with 10% discount is ₹2,880. Add 5% service of ₹144 and 5% tax of ₹151.20 for a total of ₹3,175.20. Split between 4 people, each pays about ₹794.

Understanding your result

If you ordered ₹800 of items on your own, your share is your items plus an equal part of the shared rest, with the same discount, service and tax applied, which comes to about ₹1,389.

When to use it

  • Split a restaurant bill after a group meal.
  • Share a rented house or trip costs.
  • Be fair when one person ordered much more.

Assumptions and limits

Taxes are applied in the order shown above. If your bill applies them differently, small differences can arise. The tool does not decide who pays whom.

Frequently asked questions

How do I split a bill fairly?

Add discount, service charge and tax to get the grand total, then divide by the number of people. For uneven orders, charge each person for their own items plus an equal share of shared items.

Is the tax split equally?

Yes. Tax and service are added in proportion to the food total.

What is the difference between this and the Tip Calculator?

This tool adds discount, service and tax and handles personal items. The Tip Calculator focuses on a tip percentage.

Can I split unevenly?

Enter the items only you ordered to see your share. Repeat for other people.

Does the order of tax matter?

Slightly. Here service is added before tax, which is common in restaurants.
