Figure out the tip in seconds, test different percentages, and split dinner tabs evenly among friends without awkward math at the table.
Splitting dinner shouldn't require mental gymnastics at the table. Here is how to get your numbers in seconds:
Type the check total into the bill box. Switch the currency up top if you happen to be traveling abroad.
Tap a preset button (10%, 15%, 18%, 20%, or 25%) or type your own percentage if you prefer.
Enter how many friends are splitting the meal. Leave it blank if you are covering the entire tab yourself.
Read the highlighted box to see what everyone owes, including their fair cut of the tip.
The math behind restaurant tipping is straightforward. We calculate the exact tip first, round it to the nearest cent, and then split the combined total:
Imagine three friends finish dinner together and agree to split the receipt evenly:
First, figure the gratuity: $84.50 × (18 ÷ 100) = $84.50 × 0.18 = $15.21. Add that tip right back to the food bill: $84.50 + $15.21 = $99.71 total bill.
Now split that total across three people: $99.71 ÷ 3 = $33.2366..., which rounds neatly to $33.24 per person. Each person's share of the tip is $15.21 ÷ 3 = $5.07 per diner. Honestly, payment terminals suggesting 30% tips on takeaway coffee have gotten out of hand, but 18% for solid sit-down service feels right. 18% gets my tap most often — it's the middle ground between stingy and showy, and the chip makes it one tap.
For sit-down dining in the United States, 15% to 20% remains the normal benchmark. Leave 18% or 20% if your server took great care of your table. Bumping to 22% or 25% makes sense for stellar service, whereas counter pickup orders are entirely your call.
Standard etiquette says you tip on the pre-tax food and drink subtotal so you aren't tipping on local taxes. That said, plenty of people just use the final slip number because it's simpler and gives the server a little extra pocket money. I tip on the total, honestly — the etiquette difference on a typical dinner is under a dollar, and I'd rather keep the mental load low. Our calculator works with whichever number you decide to punch in.
Customs change dramatically once you cross borders. Across much of Europe, service charges are folded into listed menu prices, so leaving 5% to 10% cash is just a friendly bonus for great care. In Japan and South Korea, tipping can actually feel awkward or insulting, so check local customs before visiting.
We divide the complete tab—tip included—straight down the middle by diner headcount. That keeps group dinners quick and painless. If someone ordered prime rib while someone else had soup, an itemized split on your own receipt is usually fairer.
Always tip on the original pre-discount total when using coupons, vouchers, or happy hour specials. Your server worked just as hard bringing that meal to your table. Calculating tip from the full menu price ensures staff aren't shortchanged by marketing promotions.
