About this tool
Splitting bills fairly is essential for dining with friends. This calculator divides total (bill + tip) by number of people, showing exactly what each person owes.
Standard tip: 15-20% for good service, 10% for poor service, 20%+ for excellent. Tip calculated on pre-tax subtotal or post-tax total (varies by region). Some restaurants add automatic gratuity for large groups (6+ people).

FAQs
How do you split a bill evenly with tip?
Formula: (Bill + Tip) ÷ Number of People. Calculate tip: Bill × Tip%. Add to bill. Divide by people. Example: $100 bill, 20% tip, 4 people. Tip = $100 × 0.20 = $20. Total = $120. Per person = $120 ÷ 4 = $30. Round up to nearest dollar: $30. App feature: can calculate tip on pre-tax or post-tax amount (regional preference).
What is the standard tip percentage at restaurants?
United States: 15-20% standard (18% average). 15% = adequate service. 18-20% = good service. 20%+ = excellent service. 10% = poor service (still tip unless truly terrible). Other countries: Europe 5-10%, Australia/Japan minimal (service included). Tip on pre-tax subtotal (common) or post-tax total (generous). Calculate: Subtotal × 0.18 = tip. Delivery: 15-20% + $2-5 minimum.
Should tip be calculated before or after tax?
Etiquette debate. Two approaches: Before tax (traditional): more accurate - tipping service, not tax. Example: $100 subtotal + $8 tax = $108. Tip on $100 = $18. Total = $126. After tax (easier math): simpler calculation. Tip on $108 = $19.44. Total = $127.44. Most people: before tax is fair. Difference is small (~$1-2). Pick one method, be consistent. Our calculator: offers both options.
How do you split a bill when people ordered different amounts?
Unequal split methods: 1) Itemized: each pays for what they ordered + proportional tip/tax. Person A: $35 food + ($35/$120) × $20 tip = $40.83. 2) Approximate: divide into groups (had drinks vs didn't). 3) Equal split: simplest but unfair if big difference. Apps: Splitwise, Venmo, Tab. Awkward conversation tip: agree on method before ordering. If one person had $10 salad, other had $50 steak, equal split is unfair.
What if someone didn't drink alcohol?
Alcohol often costs 40-60% of restaurant bill. Fair solution: 1) Calculate food + shared items (apps, dessert) equally. 2) Drinkers split alcohol costs separately. Example: $150 bill ($80 food, $70 drinks). 4 people, 2 drank. Food: $80 ÷ 4 = $20 each. Drinks: $70 ÷ 2 = $35 each (drinkers). Non-drinkers pay $20 + tip. Drinkers pay $55 + tip. Or: non-drinkers pay proportionally less tip (since tip calculated on total).
Should I round up when splitting bills?
Yes, for convenience and generosity. Round to: nearest dollar ($23.47 → $24), nearest $5 ($23.47 → $25), or even amount ($23.47 → $25). Benefits: easier cash payment (no coins), slightly higher tip (server appreciates), avoids "cheap" perception. Example: calculator says $28.63 per person. Round to $29 or $30. Multiply back: 4 × $30 = $120 total (vs $114.52 calculated). Extra $5.48 is bonus tip. Venmo: can pay exact amount. Cash: round up.
