Formula
For a bill B, tip rate t (percent) and n people:
tip=B⋅100t,total=B+tip,share=ntotal
With rounding step s, each share becomes ⌈share/s⌉×s and the group pays n times that.
Worked example
A dinner costs 240 for 4 people with a 10% tip, shares rounded up to the next whole unit.
Tip: 240×0.10=24.
Total: 264; exact share: 264/4=66.
Since 66 is already whole, rounding changes nothing.
Change the bill to 250: tip 25, total 275, share 68.75. Rounded up to 69, the group pays 276, which is 1 more than the exact total.
Common mistakes
Splitting the bill and then tipping each share, which is the same total but easy to compute wrongly person by person.
Tipping on a total that already has a service charge, so staff are paid twice.
Rounding down. Rounding each share down can leave the group short of the bill.
Forgetting that “10%” and “0.10” are different entries here; type 10.
Frequently asked questions
Should the tip be calculated before or after tax?
Etiquette in most places is to tip on the pre-tax amount, but many people tip on the total for simplicity. Enter whichever bill figure you prefer; the difference is the tax rate times the tip rate, which is small.
Is a service charge the same as a tip?
A service charge already printed on the bill is a mandatory fee, often 10 to 12%. If it goes to staff, a further tip is optional, so set the tip to 0 or a small extra.
What if people ordered very different amounts?
This tool splits evenly. For unequal orders, run the calculator once per person with their own subtotal, or split the shared items evenly and add each person's own items.
What does rounding up do?
It raises each person's share to the next whole step (for example the next whole unit). The group then pays slightly more than the exact total, and the surplus acts as an extra tip.
