Maryland tip calculator

What the calculator is actually doing

Three inputs decide almost everything: the bill, the percentage and the number of people splitting it. The tool works out the tip on the base you choose, adds it to the bill, and divides the total by the number of people. It shows the tip on its own and the tip each, because those are the two figures people argue about at the table.

The input that changes the answer quietly is Tax included in that total. Leave it at zero and the tip runs on the whole bill, which is what a card terminal does. Type the tax off your receipt and the tool subtracts it before applying the percentage. The tip falls; the bill you owe does not.

Three more inputs do work no phone calculator does. Service charge already added is the expensive one: large parties are often charged automatically, and a percentage added on top of that is a tip on a tip. What you ordered splits the bill by what each person actually had rather than dividing it equally. Rounding settles the change at the table.

Pre-tax or post-tax: which one is correct?

Neither, in the sense that no authority settles it. Tipping on the pre-tax subtotal is the older convention, and the reasoning behind it is straightforward: the server did not cook up the sales tax, and the restaurant does not keep it. Tipping on the total is simpler arithmetic and has become the default on card terminals, which almost always calculate their suggested percentages on the full amount.

The gap is small and it grows with the tax rate. In a state with no sales tax the question does not arise at all. In a city where combined state and local tax runs past 9%, tipping on the total adds roughly two per cent to the tip itself. Our state and local sales tax pages show what the rate is where you are eating.

Pick one convention and stop relitigating it. The choice matters far less than whether you tip at all.

A worked example, using the numbers the tool opens with

The calculator loads with a bill of $84.50, a tip of 20%, split between two people, tipping on the total.

• Tip: 20% of $84.50, which is $16.90
• Total: $101.40
• Each person pays: $50.70
• Tip each: $8.45

Now enter $7.00 in the tax field. The tip base drops to $77.50, the tip becomes $15.50, and the total becomes $100.00, or $50.00 each. The whole argument is worth $1.40.

The service charge case

A party of six runs up $120, and $18 of that is an automatic service charge. Enter both and the tool tips on $102, not $120, because the $18 is already gratuity. It then says what most bills do not: the $18 is 18% on its own, and adding 20% on top brings the total gratuity to 38%. That is the single most expensive tipping mistake, and it is invisible unless somebody reads the small print at the bottom of the bill.

The uneven split

You ordered $22 of an $84.50 table. Enter it under What you ordered and your share comes back as $26.40: your food plus your proportional part of the tip, rather than $50.70 for a meal half the size.

That is the useful thing to take away. The convention you use moves the number by about the price of a coffee. The percentage you choose moves it far more: at 15% on the same bill the tip is $12.68, at 25% it is $21.13.

What to tip, by service

These are customary ranges in the United States, not rules, and they vary by region and by city. They are a starting point when you have no idea.

The table stops at the common cases. Tipping has spread well beyond restaurants, and the norms outside them are weaker and less settled: a mover, a tattoo artist, a dog groomer, a furniture delivery crew. The workable test is whether a person performed a service directly for you, in a trade where tipping is customary. Where it is not customary, and for anyone who sets their own prices, no tip is expected. Counter service sits at the awkward edge of this, which is why the range above starts at zero.

Tipping is bound up with how tipped workers are paid. Federal law allows an employer to count tips toward the minimum wage and to pay a cash wage as low as $2.13 an hour, provided tips bring the total to at least the full minimum. Several states do not allow that offset and require the full state minimum wage before tips. The Department of Labor publishes both, and the difference is one reason tipping norms feel more optional in some states than others.

How tipped workers are actually paid

The offset has a name: the tip credit. An employer claiming it pays the lower cash wage and counts part of your tip toward the minimum. If tips fall short, the employer is required to make up the difference, so the minimum is a floor rather than a target. That floor is checked over a pay period rather than over a shift, which is why a slow Tuesday is averaged against a busy Saturday.

Where a state bans the credit, the worker receives the full state minimum before a single tip arrives and tips sit entirely on top. That is the mechanical reason tipping feels more like a wage subsidy in some places and more like a bonus in others. Neither arrangement changes what is customary at the table, and neither is printed on your bill.

Two further rules decide where the money lands. Tips can be pooled among staff who customarily receive them, and where the employer takes no tip credit the pool may extend to kitchen and other back-of-house staff. Managers and supervisors may not keep tips from a pool under any arrangement. The Department of Labor sets out both, and a restaurant that pools tips is not doing anything unusual.

Automatic service charges, and why they catch people out

A party of six or more is often charged an automatic service fee, typically printed on the bill as a gratuity or service charge of 18% to 20%. Some restaurants apply one to every table. It is a charge, not a tip, and legally it is treated differently: a mandatory service charge is the restaurant’s revenue rather than the employee’s tip, even where it is passed on in full.

The practical point is simpler. Read the bill before you add anything. Adding 20% on top of an automatic 20% is the single most common way people accidentally tip 40%, and it happens most often on the largest bills, where it costs the most.

If a service charge is already there and you thought the service was excellent, an extra few dollars is a choice. Doubling the percentage is not what anyone intended.

Does the suggestion on the card terminal mean anything?

No. Suggested tip buttons are configured by the merchant, and there is no standard behind them. Three things are worth knowing:

• The suggestions are usually calculated on the total, tax included, and sometimes on a total that already includes a service charge or a delivery fee.
• The lowest button on the screen is not the lowest acceptable tip. It is the lowest the merchant chose to display.
• Screens have crept upward. A terminal offering 20%, 25% and 30% is showing you a menu, not a norm.

Use the number you decided on, not the one that is easiest to press.

Is a cash tip worth more than one on the card?

To you, no. The amount is the amount, and the calculator does not care how you settle it. To the worker the differences are real, though smaller than the folklore suggests.

A tip added to a card is processed with the sale and normally reaches the employee through payroll, which means it arrives on a pay date rather than at the end of the shift, with tax withheld along the way. Federal rules allow an employer to pass on the card processing fee attributable to the tip, provided the deduction never takes the employee below the minimum wage. Several states prohibit that deduction outright.

Cash arrives immediately and in full. It is still taxable income and employees are required to report it, so the belief that cash tips are untaxed is wrong rather than merely optimistic.

None of that is a reason to carry cash you do not have, and none of it is a reason to write a smaller number on the card. If you want the tip to reach someone the same night, cash does that. If you want it recorded and paid through the normal route, the card does that.

Where this calculator stops

It divides evenly. That is the right answer surprisingly often and the wrong answer when one person ordered a salad and another ordered the tasting menu. The tool has no idea who ate what.

It also cannot tell you whether a service charge is already on the bill, whether a delivery fee reaches the driver, or whether the restaurant pools tips among kitchen staff. Those are questions for the bill and the person carrying it.

Two things the code itself flags, because they are the ones that change the answer:

• Tipping on the pre-tax subtotal is the older convention and costs slightly less. Neither convention is wrong.
• A party of six or more is often charged an automatic service fee. Check the bill before adding a tip on top of one.

The mistakes people make splitting a bill

Splitting before the tip, then adding tips separately. Everyone rounds their own share up, and the table over-tips by five or ten dollars without noticing. Total first, then divide, which is the order the tool uses.

Tipping on a discounted bill. If a coupon took $30 off, the work was still done on the full order. Tip on what the meal would have cost.

Forgetting the cash-versus-card question. How a tip is paid affects when the worker sees it, not how much it is worth. If that matters to you, how you pay is a banking question, not a tipping one.

Before you sign the receipt

• Check whether a service charge or automatic gratuity is already applied
• Decide whether you are tipping on the total or the subtotal, and stick to it
• Confirm the number of people splitting the bill before dividing
• Look at whether a delivery or service fee is separate from the tip
• Round to a whole dollar if it makes the split cleaner
