How it works
The calculator multiplies the bill by the tip percentage to produce the gratuity, adds it to the bill for the grand total, then divides by the number of people sharing. All arithmetic is plain JavaScript multiplication and division — no rounding tricks, no minimum-tip enforcement, no service-charge guesses. The currency symbol is purely cosmetic; the math is identical for dollars, euros, pounds or yen.
tip = bill × (tipPercent / 100)
total = bill + tip
perPerson = total / people
Common use cases
- Splitting a restaurant bill evenly with friends.
- Quickly checking the dollar value of a 15%, 18% or 20% tip.
- Working out a sensible tip on a coffee or bar tab.
Frequently asked questions
Should I tip on the pre-tax or post-tax amount?
Etiquette varies. In the US, tipping on the pre-tax subtotal is common; tipping on the post-tax total slightly inflates the gratuity. Either is acceptable — enter whichever bill amount you prefer.
How does the per-person split round?
It does not round; the displayed value is the exact division result. In real life, round up to the nearest dollar/euro for fairness and to avoid coin-collecting.
What is the right tip percentage?
In the US, 15–20% for sit-down restaurants is standard. Tipping conventions vary widely by country — research locally for travel.
Does it support currency-specific decimal places?
No special handling — values display with two decimal places. Currencies that do not subdivide (e.g., JPY) just round visually.
