Tip Calculator

How to use this calculator

Three tabs cover the most common tipping situations. Pick the one that fits and the results update instantly.

Tip & Split tab. Enter the bill amount before tax, choose a tip percentage using the quick preset buttons (15%, 18%, 20%, 25%) or type in a custom amount, add your local tax rate if you want to include it, and set the number of people splitting the bill. The calculator shows the tip amount, the total bill, and each person’s share.

Custom Split tab. This tab handles unequal splits where people ordered different amounts. Enter each person’s individual subtotal and their preferred tip percentage. The calculator shows what each person owes and the blended tip percentage for the whole table.

Tip by Quality tab. Not sure what to tip? Select a service quality rating from Poor to Excellent. The calculator suggests a standard tip range for that service level and computes the amounts automatically. You can override the suggested percentage if you want.

What the standard tip percentages mean

Tipping norms have shifted upward over the past two decades, and what counts as “standard” now is meaningfully different from what it was in the 1990s.

15% was the traditional standard for table service. It’s now generally considered the minimum for acceptable service, not the default. Many servers view 15% as a signal that service was below average.

18% represents neutral-to-good service. If you received what you expected without major issues, 18% is a reasonable baseline in most US markets.

20% is the new standard for good service. It’s easy to calculate and widely understood by service workers as the benchmark for satisfactory service.

25% signals excellent service or a personal preference to tip generously. In high-end restaurants or for service workers who went clearly above expectations, 25% or more is appropriate.

The standard has shifted partly because tipping income has replaced wage growth for many service workers. In most US states, tipped employees can be paid a lower cash wage than minimum wage, with tips expected to make up the difference.

Tipping in different settings:

Setting	Typical tip range
Sit-down restaurant	18–25%
Bar (drinks only)	$1–2/drink or 15–20%
Coffee shop (counter service)	0–15% (optional)
Food delivery	15–20% of order
Takeout	0–10% (discretionary)
Hotel housekeeping	$3–5/night
Taxi / rideshare	15–20%
Hair salon	15–25%
Spa / massage	18–25%

The formulas

The difference between tipping on pre-tax versus post-tax is usually small but becomes more meaningful on large bills or in high-tax states. On a $200 bill with 10% tax, the difference between 20% pre-tax and 20% post-tax is $200 × 0.20 = $40 vs $220 × 0.20 = $44. That’s $4 per table, which adds up to real income for servers across hundreds of covers per week.

There’s no right answer on pre-tax vs post-tax tipping. Convention varies by region and personal preference. The calculator lets you include tax in the base or exclude it.

Should you tip on the tax?

This is one of those small questions that generates outsized debate. The practical answer: it doesn’t matter much.

On a $100 bill with 10% tax, the difference between tipping 20% on $100 versus $110 is $20 vs $22. Two dollars. Over the course of a dinner out for four people once a month, that’s $24/year difference. Not worth overthinking.

The philosophical argument for tipping on pre-tax only: the government isn’t your server’s employer, so why compensate the server for the government’s cut? The argument for tipping on the full amount: the server’s effort was the same regardless of the tax rate, and the convenience of including tax in the tip math makes calculation simpler.

Most restaurant professionals say they don’t track or care which way customers calculate it. What matters to them is the ballpark of 18–20%+ rather than the precise calculation method.

How to split a bill unequally

When a group has mixed orders, equal splitting can create tension. The person who ordered a salad and water shouldn’t pay the same as someone who ordered steak and a bottle of wine.

The fairest approach:

1. Each person calculates their own subtotal from the itemized receipt
2. Each person tips their own percentage on their own subtotal
3. Add up individual amounts for the total

The Custom Split tab handles this automatically. Enter each person’s subtotal and their chosen tip percentage. The calculator handles the math.

The custom split approach is more accurate but requires a few minutes with the bill. For casual groups with similar orders, equal splitting is simpler and avoids the awkwardness of itemizing.

Tipping on takeout and delivery

Takeout tipping has become more common, especially since the pandemic when many restaurants pivoted to takeout-heavy models. The norms are still evolving.

Takeout directly from restaurant: 0–10% is typical. The work involved is less than full table service. Some people tip 10–15% to support restaurants they want to stay in business. There’s no social obligation, but tipping something is appreciated.

Third-party delivery (DoorDash, Uber Eats, etc.): 15–20% is standard. Delivery drivers use their own vehicles, pay for gas, and often navigate difficult parking and weather conditions. The default suggested tips on these apps tend to be on the lower end, so consider adjusting upward for difficult conditions or large orders.

Factors that justify higher delivery tips:

• Orders over $50 (flat dollar tip makes more sense)
• Bad weather or long distances
• Multiple items that required careful packing
• Excellent condition upon arrival

Order size	Suggested delivery tip
Under $20	$3–4 minimum
$20–50	15–20%
$50–100	15–20% (at least $10)
Over $100	15% minimum

The tip calculation tricks that actually work

20% in two steps: Move the decimal one place left for 10%, then double. $78 bill → $7.80 → $15.60.

15% trick: Find 10%, take half of that (for 5%), and add them together. $78 → $7.80 + $3.90 = $11.70.

Rounding up: Many people prefer to round the total to a clean number. If the total comes to $43.60 for two people, rounding to $44 or $45 each is easier than fumbling with change and often leaves a better tip percentage.

The double tax trick: In states where sales tax is around 8–9%, doubling the tax line on the bill gives approximately a 16–18% tip. Quick, close enough for many purposes.

Large parties: Most restaurants automatically add an 18–20% service charge for parties of 6 or more. Check your bill before adding an extra tip. The line item is often labeled “gratuity” or “service charge.” You are not obligated to tip on top of a mandatory service charge, though you can add more for exceptional service.

When not to tip and when the math changes

Counter service and fast food: No tip expectation. The tip prompt on tablet payment systems at counter-service restaurants is a design choice to capture optional gratuity. You’re not obligated. If you’re a regular or feel the staff goes above and beyond, a small amount is always appreciated but never required.

Mandatory service charges: When the menu says “18% service charge automatically added,” the charge replaces the tip. It goes to the restaurant and may or may not be distributed to servers depending on state law. In some cities (San Francisco, for example), service charges fund higher base wages rather than traditional tips.

Tipping on discounts and coupons: When you use a coupon or discount, tip on the pre-discount price. The server’s work was based on the full order, not your reduced payment. Tipping 20% on a $60 bill after a $30 coupon brings your tip to $12, which is 20% of $60, not 20% of $30.

Rounding for simplicity: It’s common and practical to round. If your calculated tip is $17.40 on a $87 bill, putting in $18 (20.7%) or even $20 (23%) is normal. The precision of tip calculators is useful for knowing where you are, not for leaving exact-cent tips.

The bottom line

Tipping norms in the US have drifted upward over time. The current baseline for good sit-down restaurant service is 18–20%, with 25% or more for excellent service. For delivery, 15–20%. For counter service, it’s optional.

The tip calculator takes the arithmetic off your plate. Enter the bill, choose a percentage, split by people, and you’re done. Use the custom split tab when orders vary significantly by person, removing the awkwardness of itemizing individual shares by hand.

One practical habit: set a personal default tip percentage and stick with it. Using 20% as a baseline makes every calculation quick: find 10%, double it, done. Adjust up for excellent service, down only when service was genuinely poor, not just average.

International tipping: when the US standard doesn’t apply

If you travel internationally, US tipping norms don’t transfer. In many countries, tipping is either not expected, included in the service charge, or handled very differently.

Countries where tipping is not expected or is minimal: Japan, South Korea, Australia, New Zealand, and most of Southeast Asia. In Japan, leaving a tip can be considered rude, as service quality is considered part of the job, not something requiring additional payment. In Australia, wages are high enough that tipping is optional and uncommon.

Countries where service charge is included: France and much of Europe often include “service compris” in the bill. Check before adding more. The included service charge typically ranges from 10-15%.

Countries with US-like tipping culture: Canada and Mexico have similar tipping expectations to the US, though slightly lower baselines. In Canada, 15-18% is standard; in tourist areas of Mexico, 10-15% is typical.

Countries with tipping but different mechanics: In the UK, tipping in restaurants is common (10-15%) but not as expected as in the US. Some restaurants add a discretionary service charge. If they do, you’re not obligated to tip additionally.

Region	Restaurant tip	Notes
USA/Canada	18-22%	Expected for sit-down service
UK	10-15%	Check if service charge included
France/Europe	5-10% or none	Often service compris
Japan/Korea	None	Not culturally expected
Australia	0-10%	Optional, appreciated
Mexico (tourist areas)	10-15%	USD often accepted

When you travel, a quick search for tipping customs in your destination country is worth doing before your first restaurant meal.
