How this calculator works
Formula
Tip base = subtotal, or subtotal + tax when that option is selected. Tip = tip base × tip rate ÷ 100. Unrounded total = subtotal + tax + tip. Equal share = total ÷ people. Optional rounding raises each share to the selected increment and reports the extra collected.
Worked example
For a $100 subtotal, $8 tax, 20% tip on the subtotal, and four people, the tip is $20, the bill total is $128, and each person pays $32.
Assumptions to verify
- Every person receives an equal share.
- Tax is entered as an amount and is not estimated from location.
- Optional per-person rounding can make the collected total higher than the exact bill total.
Frequently asked questions
Should I tip on tax?
Practices differ. The calculator exposes both subtotal-only and subtotal-plus-tax methods rather than prescribing one.
Why do stacked rounded shares exceed the bill?
Rounding each person’s share upward creates a visible rounding adjustment, so the collected total can exceed the exact total.
Does the calculator send my bill anywhere?
No. It performs deterministic arithmetic in your browser and does not contact a restaurant or payment service.
