The TechsGenius Tip Calculator is a free tool that calculates the tip on a bill and splits the total across any number of people.
You enter the bill, pick a tip percentage, and set the group size; the calculator returns the tip, the total, and each person's share.
Tipping norms vary by country and service type, with 15-20% common in US restaurants and very different customs elsewhere.
The split function removes the awkward table math that either shortchanges the server or overcharges one friend.
The tool is free at techsgenius.org and needs no signup.
The TechsGenius Tip Calculator is a free browser tool that handles the two calculations every shared meal ends with: how much to tip, and how much each person owes. You enter the bill amount, a tip percentage, and the number of people, and the calculator returns everything.
The math is simple and the moment is not. The end of a meal is exactly when nobody wants to do mental arithmetic in front of the group, and the common shortcuts, rounding wildly or guessing, either underpay the server or land unevenly on whoever covers the difference.
The calculator sits in the everyday finance section of the TechsGenius free tools library, the kind of tool that earns its keep through the installable TechsGenius web app, one tap away at the table where it is needed.
The calculator applies the tip percentage to the bill, adds it for the total, and divides by the group size.
Use it in three steps:
Enter the bill amount from the check.
Choose the tip percentage.
Enter the number of people and read the tip, the total, and the per-person share.
The per-person figure is the part worth having on screen. Think of it as ending the "so that's, uh, about…" moment: the number appears, everyone sees it, and the payment happens. Thirty seconds of fumbling becomes three seconds of reading.
The right tip percentage depends on where you are and what service you received, because tipping is a custom rather than a formula. The calculator computes any percentage; the choice of percentage is cultural knowledge.
The working reference points:
US restaurants: 15-20% of the pre-tax bill is the common convention for table service, with 20% increasingly treated as the standard for good service.
US counter and delivery service: Smaller percentages or flat amounts are common, and delivery tips also reflect distance and weather.
Outside the US: Customs range from similar, to modest rounding, to no tipping at all, and in some countries a service charge is already on the bill. Check the local norm and the bill itself before adding more.
The pre-tax note matters in practice: convention bases the tip on the bill before tax, though many people tip on the total for simplicity and generosity. Either way, the calculator applies your chosen percentage to the number you give it, and a glance at the bill for an included service charge prevents the classic double tip.
Splitting evenly is usually right because the fairness gained by itemizing rarely covers the friction it costs, unless the orders were genuinely lopsided. The even split is fast, social, and self-correcting over repeated meals.
The case for even splits: differences of a few dollars per person are noise, the table settles in seconds, and among people who eat together regularly, the small imbalances average out. The case for itemizing: one person ordered triple the rest, or budgets at the table differ enough that the imbalance is real money to someone. Then the polite move is the person with the large order offering to cover more, rather than the group auditing the receipt.
The calculator serves the even split directly with its per-person figure, and it serves the exception too: run it on the shared portion of the bill, and let the outlier add their difference on top.
Tipping on top of a service charge: Some bills already include service. Read the bill before adding a full tip on it.
Forgetting the tip in the split: Dividing the pre-tip bill leaves the last payer covering the whole tip. Split the total after the tip.
Guessing under pressure: Table-side mental math skews low. Three seconds with the calculator pays the server correctly.
Auditing small differences: Itemizing a bill over a few dollars costs more goodwill than it saves. Save receipt audits for genuinely lopsided orders.
It is a free browser tool at techsgenius.org that calculates the tip on a bill and splits the total across any number of people.
In US table-service restaurants, 15-20% of the pre-tax bill is the common convention, with 20% widely treated as the standard for good service. Customs differ substantially in other countries.
Convention bases the tip on the pre-tax amount, though many people tip on the total for simplicity. Either is acceptable; consistency and generosity matter more than the technicality.
Split the after-tip total evenly for most meals, since small differences are noise. When one order genuinely dwarfs the rest, that person adds their difference on top of the even share.
Yes. It is part of the 50+ free tools at techsgenius.org and runs in the browser without a signup.
The calculator returns the tip, the total, and the per-person share in one entry.
Tip percentages are customs: know the local norm and check the bill for included service.
Split the after-tip total, or the last payer quietly covers the whole tip.
Even splits win on speed and goodwill; reserve itemizing for genuinely lopsided bills.
