How do I calculate tip and split a bill?

First calculate tip: tip amount = bill × (tip percentage / 100). Then add tax: tax amount = bill × (tax percentage / 100). Total = bill + tip + tax. Finally divide by people: per person = total / number of people. Example: $100 bill, 18% tip, 8% tax, 4 people = $100 + $18 + $8 = $126 / 4 = $31.50 per person.

What is the standard tip percentage for restaurants?

In the United States, standard tip percentages are: 15% for adequate service, 18% for good service (most common), 20% for excellent service, and 22-25% for exceptional service. Tips below 15% are considered low unless service was problematic. Many restaurants suggest 18-20% on the bill.

Should tip be calculated before or after tax?

Tip should be calculated on the pre-tax subtotal. Tax is a government charge, not a service provided by staff. Calculating tip on the total including tax means you're tipping on the tax amount, which is unnecessary. Professional etiquette guides recommend tipping 15-20% on the pre-tax amount.

How do I split a bill unevenly?

For uneven splits, calculate each person's individual items plus their share of tax and tip. Person's total = their items + (their items / total items × tax) + (their items / total items × tip). Alternatively, split tax and tip proportionally: each person pays their items plus a proportional share of extras.

What is the difference between service charge and tip?

A service charge is a mandatory fee added by the restaurant (often 18% for large groups). It goes to the restaurant, not necessarily to servers. A tip (gratuity) is voluntary and goes directly to service staff. If a service charge is included, additional tipping is optional but 5-10% extra is appreciated for excellent service.

How do I handle split bills with different orders?

Track each person's individual subtotal separately. Calculate tax and tip on the total bill, then distribute proportionally. Each person pays: their subtotal + (their subtotal / total × tax) + (their subtotal / total × tip). Apps and calculators can automate this, or request separate checks before ordering.

About Split Bill & Tip Calculator

This split bill and tip calculator computes tax, tip, total cost, and per-person amounts for restaurant bills and shared expenses. It handles both even splits (equal division among all people) and provides the mathematical foundation for uneven splits using proportional distribution.

It is useful for restaurant group dining, travel expense splitting, roommate bill division, event cost sharing, calculating fair tips for large groups, determining individual costs when some people ordered differently, and settling shared expenses from trips or gatherings.

Bill Split Calculation Formulas

The calculator uses these formulas for even split calculations:

Even Split Formulas:

Tax Amount = Bill × (Tax % / 100)
Tip Amount = Bill × (Tip % / 100)
Total = Bill + Tax Amount + Tip Amount
Per Person = Total / Number of People

Example Calculation:
  Bill: $100.00
  Tax: 8% → $8.00
  Tip: 18% → $18.00
  Total: $126.00
  4 People → $31.50 per person

Uneven Split (Proportional):
Each person's share = (Their subtotal / Total bill) × Total with tip/tax

Person A ordered $40 of $100 total (40%):
  Person A pays: 40% × $126.00 = $50.40
Person B ordered $60 of $100 total (60%):
  Person B pays: 60% × $126.00 = $75.60

Bill Split Examples

Example 1: Even Split for 4 People
  Bill subtotal: $120.00
  Tax (8%): $9.60
  Tip (18%): $21.60
  Total: $151.20
  Per person: $37.80

Example 2: Couple's Dinner (2 People)
  Bill subtotal: $85.00
  Tax (7.5%): $6.38
  Tip (20%): $17.00
  Total: $108.38
  Per person: $54.19

Example 3: Large Group (8 People)
  Bill subtotal: $450.00
  Tax (9%): $40.50
  Tip (18%): $81.00
  Total: $571.50
  Per person: $71.44

Example 4: Uneven Split
  Total bill: $200 (before tax/tip)
  Person A ordered: $80 (40%)
  Person B ordered: $70 (35%)
  Person C ordered: $50 (25%)

  With 8% tax, 18% tip:
  Total with tax/tip: $252

  Person A pays: 40% × $252 = $100.80
  Person B pays: 35% × $252 = $88.20
  Person C pays: 25% × $252 = $63.00

Service Charge vs Tip

Service Charge (Auto-Gratuity):
  - Mandatory fee added by restaurant
  - Often 18-20% for parties of 6+
  - Legally belongs to restaurant (not required to go to servers)
  - Should be disclosed on menu
  - Additional tip optional (5-10% extra for excellent service)

Tip (Gratuity):
  - Voluntary payment from customer
  - Goes directly to service staff
  - Amount determined by customer
  - Tax-deductible for customer (business meals)
  - Taxable income for server

Important Notes:
  - Always check if service charge is already included
  - For large groups, ask about auto-gratuity policy
  - Service charge does NOT replace tip unless stated
  - Some restaurants distribute service charge among all staff
  - Tips typically go to your specific server

Common Split Scenarios

Scenario	Recommended Approach
Equal orders, same appetite	Even split among all people
Different order values	Proportional split based on individual subtotals
Some drank alcohol, others didn't	Split alcohol separately among drinkers only
One person had expensive item	That person pays their item + proportional share
Birthday dinner (honoree didn't pay)	Divide total among paying guests only
Kids ate free or cheap	Adults split; kids' portions excluded from per-head

Tip Calculation Quick Reference

Quick Tip Calculations (on $100 bill):

15% tip: Move decimal left one place ($10), add half ($5) = $15
18% tip: 10% ($10) + 8% ($8) = $18
20% tip: Move decimal left ($10), double it = $20
22% tip: 20% ($20) + 2% ($2) = $22
25% tip: Divide by 4 = $25

Mental Math Tricks:
  10% = Move decimal one place left
  5% = Half of 10%
  1% = Move decimal two places left

  To calculate 18%:
  10% + 5% + 3(1%) = 18%
  $10 + $5 + $3 = $18 (on $100 bill)

Tax-Inclusive Calculation Warning:
  If you calculate tip on total WITH tax:
  $100 + $8 tax = $108
  20% of $108 = $21.60 (vs $20 on pre-tax)
  You're tipping an extra $1.60 on the tax!

  Always calculate tip on PRE-TAX subtotal.
