What this does
Type the bill, choose a tip rate, say how many people are paying, and it shows three lines: the tip, the grand total, and what each person owes. Rates come from five preset buttons — 10%, 15%, 18%, 20% and 25% — or the box beside them if you want something else. The default view is a $60 bill at 18% split two ways. It runs entirely in your browser, so it is just as usable on airplane mode at the end of a meal.
How do I split a bill with the tip included?
- Enter the bill amount.
- Set Split between to the number of people.
- Click a preset rate, or type your own into the percentage box — typing a custom rate that matches a preset re-highlights that button.
- Read Per person. That is the whole share, bill and tip together, not the tip alone.
What is the tip formula?
tip = bill × rate ÷ 100, then total = bill + tip and
per person = total ÷ people. A $60 bill at 18% is $10.80 of tip,
$70.80 in total, $35.40 each between two. A more awkward one: $85.50 at 18%
between three gives a $15.39 tip, a $100.89 total, and $33.63 per head. Money
is shown to exactly two decimals.
How much is a 15 or 20 percent tip on $50?
Every preset rate against a $50 bill, with the two-way split for reference:
| Rate | Tip | Total | Each of two |
|---|---|---|---|
| 10% | $5.00 | $55.00 | $27.50 |
| 15% | $7.50 | $57.50 | $28.75 |
| 18% | $9.00 | $59.00 | $29.50 |
| 20% | $10.00 | $60.00 | $30.00 |
| 25% | $12.50 | $62.50 | $31.25 |
In the US, 15–20% of the bill is the usual band for table service, with 18% as a common middle and more for exceptional service. Counter service, delivery, taxis and haircuts all follow different local habits — the custom field exists so the tool does not argue with yours.
Should I tip on the amount before or after tax?
Your call: there is no separate tax field, so the tip is a straight percentage of whatever you type into Bill amount. To tip on the pre-tax figure, enter the subtotal from the receipt rather than the amount charged, then add the tax back yourself. Entering the post-tax total is simpler and costs a few cents more.
What if the total will not divide evenly?
The per-person figure is the exact division rounded to the nearest cent, so a $100.00 total across three people shows $33.33 each — a cent short of the bill. Someone has to cover the difference, or you round the tip up until the split is clean, which is often easier at the table anyway.
What happens if I leave a field empty?
Nothing breaks. A blank or negative bill is treated as zero, a blank rate as 0%, and the head count is floored to a whole number with a minimum of one — so 0 people is read as one person, and 2.9 people as two. You never get a division-by-zero error mid-meal.
