Tip Calculator

An $84.50 bill with an 18% tip split three ways works out to a $15.21 tip, a $99.71 grand total, and $33.24 owed per person. A tip is a straight percentage of the bill: multiply the bill by the tip rate, add the two together, and divide by the number of people for an even split.

Tip on the pre-tax amount if you want to be exact

Sales tax is already the government's cut, so tipping on the pre-tax subtotal is the technically correct base. In practice most people tip on the total shown — a small difference either way.

Splitting 3 ways lands at $33.24 each

Rounding each person up to a whole dollar covers the cents and nudges the tip up a touch — handy when everyone throws in cash. On small bills, a flat round-up often beats a strict percentage.

How to calculate tip by hand

Multiply the bill by the tip percentage: $84.50 × 0.18 = $15.21.
Add the tip to the bill for the grand total: $84.50 + $15.21 = $99.71.
Divide by the number of people: $99.71 ÷ 3 = $33.24 each.

How does the tip calculator work?

The arithmetic is deliberately simple: tip = bill × percent / 100, grand total = bill + tip, per-person share = grand total ÷ number of people — no external data or conventions baked into the math. The percentage is applied to the full amount entered; if a receipt separates tax, the choice of pre-tax or post-tax figure is yours, since the calculator taxes whatever number it is given. The split divides evenly and does not weight by what each person ordered. The preset buttons span 15% to 25% in the steps people most commonly reach for.

Frequently asked questions

How much is an 18% tip on $84.50?

$15.21, bringing the total to $99.71. A quick mental route: 10% is $8.45, double it for 20% ($16.90), then shave a little — or add half the 10% figure to reach 15% and nudge up.

How do you split a bill with tip evenly?

Add the tip to the bill first, then divide by the number of people: ($84.50 + $15.21) ÷ 3 = $33.24. Splitting bill and tip separately gives the identical result, since division distributes over the sum.

How much more is a 20% tip than 18%?

Two percent of the bill — $1.69 on $84.50, or about 56 cents per person in a three-way split. Each percentage point costs bill ÷ 100, which makes jumping between presets easy to price.

How accurate is this tip calculator?

The math is deterministic — the same inputs always produce the same output, and the formula is shown above. Accuracy of the answer for your situation depends on how well your inputs match reality and how well the formula models the question.

Why is my bank's number different?

Banks add fees, taxes, insurance, and product-specific terms that this calculator deliberately omits to keep the math transparent. Use this to sanity-check a quote, not to replace it.
