What this calculator is solving

You do not need to memorize the formula first. Start by matching each input label on the calculator to the number, date, unit, or setting you actually have.

How to read the answer
Read the headline result first. Then look at the smaller supporting lines because they explain the parts behind the answer, such as totals, units, ranges, or formula steps.
- Total is subtotal plus tip plus optional tax.
- Tip shows the dollar amount from the tip percent.
- Per person divides the total evenly by the number of people.
Common mistakes to avoid
If the answer looks strange, the most likely cause is a small input mismatch: the wrong unit, date, weight, scale, mode, or policy assumption.
- Check whether the receipt already includes service charge or gratuity.
- Check whether you want to tip before tax or after tax.
- For uneven splits, calculate each person separately.
