How to use the tip calculator
- Enter the bill amount from your receipt.
- Choose a tip percentage — 15%, 18%, 20%, 22%, 25% or your own.
- Enter how many people are splitting the bill.
- Optionally enter the sales tax shown on the receipt to tip on the pre-tax amount, and switch on round up to make each share a whole number.
The formula
Tip = (Bill − Tax) × Tip % ÷ 100 Total = Bill + Tip Per person = Total ÷ Number of people
Worked example
Dinner for two comes to $85.50 and you want to leave 18%:
- Tip = $85.50 × 0.18 = $15.39
- Total = $85.50 + $15.39 = $100.89
- Each person pays $50.45, or $51.00 if you round up (a 19.3% tip)

Quick mental math for tips
- 10%: move the decimal point one place left. $64.00 → $6.40.
- 20%: double the 10% figure. $6.40 × 2 = $12.80.
- 15%: take 10% and add half of it. $6.40 + $3.20 = $9.60.
- 18%: take 20% and subtract 10% of that. $12.80 − $1.28 = $11.52.
- 25%: divide the bill by four. $64 ÷ 4 = $16.
Tips on tipping
- Check for an included gratuity, especially with groups of six or more, so you don’t tip twice.
- Tip on the full price when you use a coupon or gift card — the server did the same work.
- Card vs cash: tipping in cash often reaches staff faster, but both are fine.
- Payment screens at counters often suggest 15–25%; the “custom” or “no tip” option is always acceptable for counter service.
Tipping when travelling
Tipping customs vary widely. In Canada they are close to the US. In the UK and Ireland 10–12.5% is normal at restaurants unless a service charge is on the bill. In Australia and New Zealand tipping is appreciated but not expected. Across much of Europe locals round up or leave 5–10%. In Japan and South Korea tipping is generally not part of the culture and can even cause confusion. The calculator works in any currency.
When a bill is in another currency, tip in that currency where possible; card machines abroad sometimes offer to charge you in dollars, which usually comes with a poor exchange rate.
