Split Bill Calculator – Split With Tax & Tip Per Person

This split bill calculator divides a check fairly — bill, tax and tip totaled, then split evenly per person, with each person’s share of the tip shown so nobody has to do napkin math.

Splitting Without the Awkward Pause

The fair split everyone actually means: (subtotal + tax + tip) ÷ people, tip computed on the pre-tax amount. The calculator keeps the components visible — grand total, total tip, tip per person — because disputes at the table are almost always about what the number includes, not the arithmetic.

Worked Example (Verified)

• $120 bill, 18% tip, no tax entered (already included): tip = $21.60, total = $141.60, split 4 ways = $35.40 each
• Same bill with 8% tax: total = 120 + 9.60 + 21.60 = $151.20 → $37.80 each — the tax line is the difference between a fair split and a quiet subsidy for whoever does the math

Splitting Etiquette, Briefly

• Even split assumption: this calculator splits evenly — right for shared plates and similar orders. When one person had the lobster and three had salads, itemized splitting (or the lobster-eater’s gracious overpay) keeps friendships solvent.
• Round up, not down: if the per-person number is $37.80, paying $38–40 each is the social convention that keeps servers whole and arithmetic finished.
• Whoever booked, organized or chose the expensive venue traditionally absorbs surprise extras (corkage, the shared appetizer nobody remembers ordering).
• Large groups: check whether the restaurant already added a service charge/gratuity (common for 6–8+) before tipping on top.

Frequently Asked Questions

How do you split a bill with tax and tip?

Add tax and tip (tip on the pre-tax subtotal) to get the grand total, then divide by the number of people. $120 + 8% tax + 18% tip = $151.20; four ways is $37.80 each.

Should tip be calculated before or after tax?

Convention (and most etiquette guidance) says pre-tax — you tip on the food and service, not on the government’s cut. Some people tip on the total; the difference is small and the generosity is never criticized.

What is a standard tip percentage?

In the US: 15–20% for table service (18–20% increasingly standard in cities), 10% for buffets, a dollar or two per drink at bars. The example uses 18%.

How do I split a bill when people ordered differently?

True itemized splitting means each person totals their own items, then adds their proportional share of tax and tip (their subtotal share × the tax and tip rates). This calculator’s even split covers the common shared-order case.

What if the restaurant already included gratuity?

Then the “tip” is in the bill — enter it as part of the subtotal with tip set to 0 (or add a few percent extra only if service earned it), and do not double-tip by accident.
