FAQ
Can I split a pre-tax amount?
Yes. Switch the tax mode to "exclusive" to apply the specified tax rate before distributing the total across participants.
How do rounding and representative adjustments work?
Choose round half to nearest, up, or down along with the unit (1/10/100). Any remaining difference is collected by the representative so the total always matches.
How can I share the results?
Use the copy URL button to generate a link with all inputs, or scan the QR code displayed under the results to share quickly in person.
What should I enter first for a group meal?
Enter the bill total, tax mode, and participants first. Then adjust weights or fixed amounts for people who ordered more or less before checking rounding.
How precise are the rounded shares?
The calculator keeps internal precision, rounds each participant by your selected unit, and assigns any remaining difference to the representative so the collected total still matches the bill.
How to use Split Bill Calculator (tax, weights, rounding, QR) effectively
What this calculator does
This page splits a restaurant bill or shared purchase across participants, including inclusive or exclusive tax, weighted shares, fixed amounts, representative extra payments, and QR sharing.
Input meaning and unit policy
Bill total and fixed amounts use the selected currency display. Weights are ratios, so a person with weight 2 pays twice the weighted share of a person with weight 1 after fixed amounts and tax handling are applied.
Use-case sequence
Start from the sample values or your receipt total, set the tax mode, add every participant, then adjust weights for people who ordered more. Calculate once, review the rounding adjustment, and share the QR code or result URL.
Common mistakes to avoid
Do not enter a pre-tax subtotal while leaving tax mode on inclusive. Also avoid using representative extra for both tips and rounding unless the representative really should cover both amounts.
Interpretation guidance
Use exact allocation to audit the weighted split, final share for the amount to collect, and adjustment to see who absorbs rounding. The representative row should be checked before sharing the result.
