Tip Calculator

The tip screen has gotten a little out of hand. You grab a coffee, they spin the tablet around, and it's already asking for 20, 25, 30 percent before you've done anything but stand there. That nudge is the whole point of the design, and it's why people often overtip because they feel guilty, or leave a low tip out of annoyance, and feel a bit weird either way. This is here to take the guilt out of it: put in the bill, see what a fair tip actually comes to, and tip that, with no pre-set buttons pressuring you into a number.

Splitting with a group? It divides the whole thing evenly, tip and all, so nobody's stuck doing long division while the server waits. It can add sales tax on top without tipping on it, round to a clean cash number, or work backward from the exact total you want to hand over.

1. Enter the bill. Use the pre-tax subtotal or the full total, whichever you tip on.
2. Pick a tip percentage, or type your own. The presets are a starting point, not an instruction.
3. Splitting it? Set the number of people and each share shows up, tip included.
4. Read the tip, the total, and what each person owes. It all updates as you type.

Want the extras, open the tax, rounding, and currency section: add local sales tax so it lands in the total but doesn't get tipped on, round the total up to the nearest dollar or five for cash, or round each person's share up so the split always covers the bill, and there is a currency picker for traveling. When you're set, copy a one-line summary or share a link that reopens the same split.

Here's the honest version, not the one the checkout screen wants you to pick.

For a sit-down restaurant with a real server, 18 to 20 percent is the normal range for good service, and a lot of people just round to 20. That one matters, because servers across most of the US are paid a lower tipped wage, so the tip isn't a bonus, it's the actual paycheck, and that is worth tipping accordingly.

Counter service is where the screen gets pushy. Somebody handing you a bagel and flipping the tablet to a 25 percent prompt is asking for full restaurant tipping on zero table service. A buck in the jar, or nothing, is completely fine, and tapping "no tip" on a sale that never used to have one doesn't make you a bad person. The rest runs looser too:

• Coffee or a quick counter order: a buck or two, or nothing, no guilt.
• Bartender: a dollar or two a drink, or 20 percent on a tab.
• Delivery: 15 to 20 percent, more if it's pouring or the order's big or far.
• Haircut, nails, spa: around 20 percent, someone worked on you for a while.
• Taxi or rideshare: 10 to 20 percent, or just round up.

The through-line: tip generously where a person actually served you, and don't let a default button talk you into tipping the same on a self-serve counter.

Say the bill's 137.50, you tip 20 percent, and there are five of you. The tip's 27.50, the total's 165, and split five ways that's 33 each, so nobody has to throw in 35 and settle up later.

Even splitting is fair when everyone ate about the same. If one person got the steak and everyone else had a salad, it isn't, and no calculator fixes that one for you.

People argue about this more than it deserves. You're tipping for the service, and tax isn't part of the service, so the pre-tax subtotal is the technically-correct base, though the money at stake is tiny. On a 100-dollar meal with 8 percent tax, tipping 20 percent on the 100 versus the 108 is a difference of about a dollar sixty. Tip on whatever number's in front of you, or flip on the tax option and enter the subtotal if you want it exact.

You don't need the tool for a ballpark.

• 20 percent: take 10 percent (move the decimal one spot left) and double it. On 45 dollars, 10 percent is 4.50, so 20 is 9.
• 15 percent: the 10 percent number plus half of it. On 45, that's 4.50 plus 2.25, so 6.75.
• 18 percent: a little under 20. Do the 20 trick and take a bit off.

Close enough to judge it on the spot. The tool nails the exact cents and the split.
