About this tool

Tip Calculator splits a bill across N people, applies a tip percentage, and rounds the per-person amount to a configurable currency precision. It also reports the over- or under-payment if you prefer to tip on the payment-method total (the credit-card subtotal, for example) rather than on the per-person split — useful when the rounding of the per-person amount does not equal the rounding of the method total. The tool is plain arithmetic; it does not decide whether tipping is appropriate in your context.

When to use it

  • Splitting a restaurant bill evenly with a tip included
  • Working out the per-person amount when one person paid and the others owe back
  • Adjusting the tip percentage to land on a round per-person total

When not to use it

  • You need to split items unevenly (one person had the steak, two had the salad) — this tool is even split only
  • You need to convert the tip into a different currency — do the conversion separately, the calculator does not have a rate feed
  • You need to track tips for tax purposes — the tool does the math, but you need a bookkeeping tool to record it

Frequently asked questions

Should I tip on the pre-tax or post-tax total?

In the US, the convention is to tip on the pre-tax total (the subtotal before tax is added). Some servers prefer a tip on the post-tax total because it reflects the actual bill. There is no universal answer — the tool reports both, so you can pick.

How do I handle a tip-on-payment-method that doesn't match the per-person split?

If the credit-card tip total rounds to a different value than the per-person tip total (because of how the rounding accumulates), the page shows both. Pick the one that matches how the restaurant will see the charge.
