Bill Splitter for Equal and Custom Shares

This bill splitter turns one receipt into clear payment amounts. Enter the pre-tax subtotal, tax rate, tip percentage, and group size to see the final total and each person's share.

Use equal shares when everyone pays the same amount. Use custom shares when orders, budgets, or agreed contributions differ. The percentages keep the allocation rule visible instead of leaving the group with a guess.

The tool separates tax and tip from the subtotal, making it easier to check the receipt, spot an included service charge, and explain changes caused by the tip base or rounding setting.

DEFAULT EXAMPLE
Pre-tax subtotal$96.00
8% tax$7.68
20% tip$19.20
Final total$122.88

Use this bill splitter for

  • Restaurant meals where the group wants one quick equal split.
  • Different orders where each person needs a custom share.
  • Tax and tip calculations before dividing the final amount.
  • Rounded payments when a group prefers whole-dollar amounts.

How to Use the Bill Splitter

Start with numbers everyone can verify on the receipt. Choose the split rule, review each amount, and agree on cents or whole-dollar rounding.

1

Enter the subtotal

Read the pre-tax subtotal from the receipt and enter it. Keep mandatory service charges or existing gratuity separate until you know how the bill describes them.

2

Add tax and tip

Enter the tax and tip percentages. Decide whether the tip should use the subtotal alone or the subtotal plus tax, then read the label shown in the result.

3

Choose a split rule

Select equal shares for a simple group payment. Choose custom shares when people ordered different items, agreed on different contributions, or need a weighted split.

4

Review every amount

Confirm that the allocation is 100%, check the total due, and turn on rounding only if the group accepts the difference. Copy the breakdown or reset the example for the next receipt.

How the Bill Splitter Formula Works

Tax is calculated from the subtotal first. The selected tip base then produces the tip, and the final total is allocated according to the chosen split method.

tax = subtotal × tax rate
tip base = subtotal, or subtotal + tax
tip = tip base × tip rate
total due = subtotal + tax + tip
equal share = total due ÷ people
custom share = total due × share percentage

With a $96 subtotal, 8% tax, and 20% tip on the subtotal, tax is $7.68, tip is $19.20, and the total is $122.88. Four equal shares are $30.72; a 40% share is $49.15 and a 10% share is $12.29.

Complete worked example

$96 subtotal split four ways

Equal splitting is only one option. The same total can be allocated by percentages when one person ordered more or the group agreed on a different contribution.

Pre-tax subtotal
$96.00
Tax at 8%
$7.68
Tip at 20%
$19.20
4 equal shares
$30.72 each
40 / 30 / 20 / 10 shares
$49.15 / $36.86 / $24.58 / $12.29

Equal Split or Custom Shares?

An equal split is the fastest way to divide a shared meal, subscription, or group order. It works when the receipt is one shared cost; the calculator divides the final amount, including entered tax and tip, by the group size.

A custom split is better when the receipt is not equal. Percentages can represent item totals or agreed contributions. They must total 100%, and the tool flags the allocation when they do not.

The percentage applies to the final amount due, not only the subtotal. If tax or tip should differ by person, calculate those pieces separately and use this tool for the agreed final allocation.

Check for an included charge

Look for service charge, automatic gratuity, included tip, hospitality fee, delivery fee, or another mandatory line before adding a new percentage. The calculator can show the math you enter, but it cannot decide whether the receipt has already added gratuity.

Context still matters

Where a Bill Splitter Helps Most

The calculator makes the allocation explicit, but the group still chooses the rule. These situations show which mode fits and what to check before paying.

Restaurant meals

Equal shares are convenient when dishes were shared. Custom shares are more transparent when one person ordered a larger entree, alcohol, or an item the rest of the group did not use.

Delivery and takeout

Separate delivery, platform, small-order, and service fees from the food subtotal when the receipt lists them. Ask the group whether those costs are shared equally or assigned by agreement.

Friends and household costs

A one-time bill splitter can divide a known amount, but recurring rent, utilities, or reimbursements may need a shared-expense system with dates and payment tracking.

Avoid common input mistakes

Bill-Splitting Edge Cases to Check

A split can be mathematically correct but still feel wrong when the starting number or rule is unclear. Check these points before paying.

Tax is already included

Do not add the same tax twice. If the amount you enter is already tax-inclusive, set tax to 0% or find the separate pre-tax subtotal before using the percentage calculation.

Custom shares do not total 100%

The result stays unavailable until custom percentages total exactly 100%. This prevents a missing person or an accidental 90% allocation from producing a misleading breakdown.

Cents do not divide evenly

A total can leave a cent remainder or create awkward cash amounts. Whole-dollar rounding is optional; the displayed difference tells the group what the convenience costs.

Know the limits

A Clear Split Is Not a Receipt Policy

This free bill splitter performs arithmetic in the browser. It does not read receipts, identify dishes, verify a restaurant's fee policy, or decide what a fair contribution should be.

For a reliable result, agree on the subtotal, tax, tip base, and allocation rule first. Discounts, coupons, deposits, gift cards, mandatory fees, and separate tax rates may need a manual adjustment.

No account is required, and entered bill values stay on the page while you use it. Check the final receipt and payment screen when gratuity or a service charge may already be included.

Quick answers

Bill Splitter FAQ

What does a bill splitter calculate?

It adds the tax and tip entered for a subtotal, calculates the final amount due, and divides that amount equally or by custom percentages. The per-person breakdown stays visible so the group can review the rule.

How do I split a bill evenly?

Enter the subtotal, tax, and tip, set the number of people, and choose Equal shares. The calculator divides the final total by the group size and shows the same amount for each person.

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

Choose Custom shares and enter each person's percentage of the final total. The percentages must add up to 100%; use the allocation badge to confirm the rule before copying the results.

Can I use this as a restaurant bill splitter?

Yes. Enter the restaurant subtotal, tax rate, and group tip, then choose equal or custom shares. Check the receipt first for automatic gratuity, service charges, discounts, and fees.

Should tax and tip be split equally?

That is a group decision. Equal shares divide the final total evenly, while custom shares assign the final amount by percentages. If the receipt has special fees or different tax treatment, agree on those details first.

How do custom shares work?

A custom percentage represents a person's portion of the final amount due. For example, 40%, 30%, 20%, and 10% must total 100%, and each percentage is multiplied by the final total.

What happens when the split does not divide into whole dollars?

Leave rounding off to keep the exact cent-based amount, or turn on rounding to round every share up to a whole dollar. The tool displays the added difference so the group can approve it.

Is this bill splitter free and private?

Yes. The tool is free, needs no account, and performs the basic calculation in your browser. It does not need a bill upload or a calculation request to a server.
