How It Is Calculated
Tip = bill × (percent / 100). Total = bill + tip. Per person = total ÷ party size.
Tip = Bill × (r/100) | Total = Bill + Tip | Each = Total / n
Worked examples
$85 bill, 20% tip
Tip $17 → total $102; four people pay $25.50 each.
Post-tax tipping
$85 subtotal + $7 tax = $92; 18% on subtotal = $15.30 tip (not on tax).
Large party auto-gratuity
Some venues add 18–22% for groups of 6+—check the receipt first.

Frequently Asked Questions
How much should I tip?
Standard tip: 15-20% of bill. Good service: 18-20%. Excellent service: 20-25%. Poor service: 10-15% or less. Adjust based on service quality, location, and local customs. Some restaurants include service charge—check your bill. Tipping culture varies by country.
How is tip calculated?
Tip Amount = Bill × (Tip Percentage / 100). Total = Bill + Tip. Example: $50 bill, 18% tip: Tip = $50 × 0.18 = $9. Total = $50 + $9 = $59. The calculator does this automatically and splits per person if needed.
Should I tip on tax?
Generally, tip on pre-tax amount (subtotal). However, many people tip on total including tax for simplicity. Both are acceptable. Example: $50 subtotal + $4 tax = $54 total. Tip 18% on $50 = $9, or on $54 = $9.72. Difference is usually small.
How do I split the bill?
Per Person = Total / Number of People. Example: $59 total, 4 people: $59 / 4 = $14.75 per person. The calculator shows total, tip, and per-person amount. Make sure everyone pays their share, including tip. Some apps can split bills automatically.
