Tipping Customs Vary
15-20% standard, 10% considered low.: optional, often 10-12.5% when service charge not included. Most European countries: 5-10% on good service, rounding up to a whole number common., tipping uncommon and can be culturally awkward.
Service Charge Handling
If the bill already includes a service charge or auto-gratuity (often 18-20% for groups), no additional tip is expected. Check the bill before calculating — double-tipping is a common mistake with group dining.
Quick example
With bill amount of 80 and tip of 18 (plus number of diners of 4), the result is 94.40. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Bill Amount, Tip %, and Number of Diners. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.
What's happening under the hood
Tip equals bill times tip percentage. Total is bill plus tip. Per-person divides total by diners. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Why run the calculation
Utility bills creep. Small annual increases stack into meaningful differences over a decade. Running this once a year and switching providers when the gap widens is one of the easiest ways to keep household costs in check.
What this doesn't capture
Usage varies month-to-month; tariffs change; discounts come and go. The figure here is a clean baseline — your actual annual bill will fluctuate around it. Use the calculation to benchmark providers, not as a prediction of a specific bill.
