Tip Calculator: Gratuity and Bill Splitting

Table of Contents - Tip

How to Use This Calculator - Tip

Enter the Bill Amount (subtotal before tax, or total—you choose which to tip on).

Select whether to tip on Pre-tax Amount or Total Bill.

Select or enter your Tip Percentage: common options are 10%, 15%, 18%, and 20%.

Enter the Number of People for bill splitting.

Click "Calculate" to see results. The output displays:

  • Tip amount
  • Total bill (original plus tip)
  • Per-person share
  • Rounding options for convenience

The Core Principle: Percentage of Bill

Tipping calculates a percentage of the bill as a gratuity for service.

Basic tip formula: Tip = Bill Amount × (Tip Percentage / 100)

Total with tip: Total = Bill Amount + Tip

Per-person split: Per Person = Total / Number of People

Tip on pre-tax versus post-tax: Pre-tax tipping: Calculate tip on subtotal before tax is added. Post-tax tipping: Calculate tip on total including tax.

Pre-tax is considered proper etiquette since tax goes to the government, not the server. However, the difference is typically small.

Example: $80 meal with 8% tax = $86.40 total 15% tip on pre-tax: $80 × 0.15 = $12.00 15% tip on post-tax: $86.40 × 0.15 = $12.96 Difference: $0.96

How to Calculate Tips Manually

Mental math shortcuts:

10%: Move the decimal point left one place. $85.00 → $8.50

20%: Calculate 10%, then double it. $85.00 → $8.50 → $17.00

15%: Calculate 10%, then add half of that. $85.00 → $8.50 + $4.25 = $12.75

18%: Calculate 20%, then subtract 10% of that. $85.00 → $17.00 - $1.70 = $15.30

Full calculation example: Bill: £80 (pre-tax) VAT: 20% = £16 Tip: 15% on pre-tax = £12 Total: £80 + £16 + £12 = £108 Split 4 ways: £108 / 4 = £27 per person

Real-World Applications

Restaurant dining. Calculate appropriate gratuity for table service.

Delivery services. Tip delivery drivers for food, groceries, or packages.

Taxi and rideshare. Add gratuity to fare for driver service.

Salon and spa services. Tip hairstylists, massage therapists, and aestheticians.

Bar service. Calculate tips on drink tabs for bartenders.

Group dining. Split bills fairly including proportional tip amounts.

Scenarios People Actually Run Into

The automatic service charge. Many UK restaurants add 12.5% service. Check your bill before adding more.

The group size threshold. Restaurants often add automatic gratuity for parties of 6-8 or more. Verify before tipping again.

The poor service dilemma. Reducing or eliminating tip for genuinely poor service is socially acceptable. 10% signals dissatisfaction while still compensating.

The takeout question. Tipping on takeout is becoming more common, but typically at lower rates (10-15%) than dine-in.

The international difference. US servers depend on tips (15-20% expected). UK service charges are common. Japan has no tipping culture.

Trade-Offs and Decisions People Underestimate

Pre-tax versus post-tax. The "correct" base is debated. Pre-tax is technically proper; post-tax is simpler. The difference is usually small.

Service quality adjustment. Exceptional service deserves 20%+. Standard service warrants 15-18%. Poor service may justify 10% or less.

Rounding for convenience. Rounding the tip or total to a whole number simplifies cash payments and mental math.

Itemized versus equal splits. Equal splits are easy but may be unfair when orders vary significantly. Itemized splits are fairer but more complex.

Counter service versus table service. Full table service traditionally warrants higher tips than counter service.

Common Mistakes and How to Recover

Double-tipping. Check for automatic service charges before adding your own tip. Many group bills include gratuity.

Tipping on tax. Tax goes to the government. Tip on the pre-tax subtotal for proper etiquette.

Forgetting tip in budget. A $100 dinner becomes $115-120 with tip. Factor gratuity into spending plans.

Awkward splits. Use the calculator to determine exact per-person amounts rather than guessing and creating imbalances.

Undertipping in the US. 15% is minimum for acceptable service; 20% is standard for good service. US servers rely on tips for income.

Related Topics

Service charges. Automatic gratuity added to bills, especially for large groups or in certain regions.

Tipping etiquette. Cultural norms vary widely by country and service type.

Living wage debate. Discussion about whether tips should supplement or replace fair base wages.

Tip pooling. Systems where tips are shared among staff members.

How This Calculator Works

Tip calculation:

if tipOnPreTax:
  tipBase = subtotal
else:
  tipBase = subtotal + tax

tipAmount = tipBase × (tipPercentage / 100)

Total calculation:

totalBill = subtotal + tax + tipAmount

Split calculation:

perPerson = totalBill / numberOfPeople

Rounding options:

roundedTip = round(tipAmount) // nearest whole
roundedTotal = round(totalBill) // nearest whole
roundedPer = ceiling(perPerson) // round up for splits

Percentage presets:

10% - minimum for poor service
15% - standard for acceptable service
18% - standard for good service
20% - generous, excellent service
25% - exceptional service or special occasions

FAQs

Should I tip on tax?

Technically, tip on pre-tax subtotal. Tax goes to government, not server. However, the difference is typically small.

How do I avoid double-tipping?

Check your receipt for automatic service charge (common for groups of 6+). If present, additional tip is optional.

Can I split the bill unevenly?

The basic calculator splits equally. For itemized splits, calculate each person's share first, then apply same tip percentage.

What's standard in the UK?

10-15% if no service charge. Many restaurants include 12.5% service—check your bill.

Does this work for delivery?

Yes. Enter delivery total and apply 10-15% for standard service, more for bad weather or large orders.

Can I round the tip?

Yes. Use rounding options to round tip or total to nearest whole number for cash payments.

Is tipping mandatory in the US?

Legally no, but socially yes. 15-20% is expected for table service. Servers depend on tips as significant portion of income.

How do I tip without a calculator?

10%: move decimal left. 20%: double that. 15%: average of 10% and 20%. These mental shortcuts work quickly.
