Should I tip on the pre-tax or post-tax amount?

Many diners tip on the pre-tax food and drink subtotal, but habits vary by region and personal preference. Pick one base and stay consistent when comparing restaurants. This tool uses whatever subtotal you enter.

How does the per-person split work?

After computing tip and total, the calculator divides the tipped total by the number of people for an even split. It does not automatically weight uneven orders or separate alcohol lines unless you adjust offline.

What if the bill already includes a service charge?

Read the receipt. Mandatory service charges often go to staff under house rules, but additional tip etiquette differs. Avoid blindly adding another full percentage on top without checking.

Why does my cash tip differ from the calculator?

Cash is commonly rounded for convenience. Use the exact tip as a floor or target, then round intentionally. Card payments may force exact cents.

Do tipping norms work the same when I travel?

No. Some countries include service, tip modestly, or discourage tipping. This calculator only handles arithmetic; follow local custom and posted guidance.

Is 20% always the “right” tip?

There is no universal right percentage. Service quality, country, industry (hair salon, rideshare, restaurant), and income norms all matter. Choose a rate that matches your context and means.

How should I tip for delivery versus dine-in?

Delivery often involves drivers and platforms with their own fee structures. Decide whether app fees already compensate the courier, then tip accordingly. Dine-in percentages are not always the correct mental model for drop-off.

Can I enter a flat tip instead of a percent?

If you think in dollars (for example $5 on a small check), compute the effective percent as tip ÷ subtotal × 100, or simply add the flat amount to the subtotal for a total. Percent mode is for rate-based tips.

What about coupons or gift cards on the check?

Restaurants differ on whether tip should reflect the original priced meal or the amount actually charged. When unsure, ask the server or follow the tip-line suggestion on the receipt.

Does sales tax change the tip formula?

Tax changes the receipt total but not the tip formula itself. Tip = rate × chosen base; total = base components you decide to include + tip. Clarity about the base prevents double-counting tax into the tip unintentionally.

How do large parties and auto-gratuity interact with this tool?

Enter the same percent printed as auto-gratuity to verify the line item, or enter zero additional tip if the auto charge already covers what you intend to leave. Match the restaurant’s policy, not a generic blog rule.

Are bill amounts stored?

No. Tip calculations run locally in your browser for this tool.

Tip Calculator

Tipping math should not slow the end of a meal: you need a clear tip amount, a grand total, and—when splitting—each person’s share. This tip calculator lets you enter a subtotal, choose a common percentage or a custom rate, and optionally divide among guests. Customs differ by country, service type, and whether tax or automatic gratuity already appears on the check. Use the numbers as a quick arithmetic aid, then follow local etiquette and the bill’s own service-charge line so you neither underpay staff expectations nor double-tip by accident.

How to use

Enter the subtotal you intend to tip on—often the food-and-drink total before sales tax, unless local habit or house policy says otherwise.
Choose a tip percent such as 15%, 18%, or 20%, or type a custom percentage that matches the service and your budget.
Read the tip amount and the all-in total so you know what the card charge or cash handshake should cover.
Optionally enter party size to see an even per-person share of the tipped total.
If the check already lists a mandatory service charge or large-party auto-gratuity, decide whether any additional tip still applies before stacking percentages.
For cash tips, round up to a convenient bill if you prefer; start from the exact computed tip so the round-up stays intentional.
Compare tipping on pre-tax vs tax-inclusive bases when the receipt makes both numbers available—culture and personal preference both play roles.
Delivery, takeout, counter service, and fine dining often follow different norms; adjust the percent for the service model you received.
When splitting uneven orders, use the even-split figure as a starting point, then settle differences offline so one calculator result does not force an unfair share.
Double-check currency and decimal places on foreign menus so a 10 vs 100 confusion does not become an accidental 100% tip.

Examples

$86.00 bill, 18% tip → tip $15.48; total $101.48; three-way split ≈ $33.83 each.
$42.50 lunch at 20% → tip $8.50; total $51.00.
$120.00 tab, 15% tip, four guests → tip $18.00; total $138.00; ≈ $34.50 each.
Large party: 18% on $400.00 → tip $72.00; total $472.00 (compare to a printed auto-gratuity line).
Coffee $4.50 with a $1.00 flat tip ≈ 22.2% effective tip.
Pretax $200.00 vs tax-inclusive $216.00 at 20%: tip $40.00 vs $43.20—know which base you chose.
$67.80 at 18% → tip $12.20; total $80.00 (handy cash round).
Two guests, $55.00, 15% → tip $8.25; total $63.25; ≈ $31.63 each.
Custom 22% on $95.00 → tip $20.90; total $115.90.
Takeout $28.00 at 10% → tip $2.80; total $30.80 (adjust to your local takeout customs).

Formula / Method

Tip = subtotal × (tip% ÷ 100). Total = subtotal + tip (plus any tax you chose to include in the entered subtotal). Per-person share ≈ total ÷ party size for an even split. Effective tip% for a flat tip = (flat tip ÷ subtotal) × 100.

Assumptions & Limitations

Assumes a single subtotal and tip rate unless you adjust manually. Does not encode country etiquette, employer tip-pooling rules, or platform fee policies. Even splits ignore uneven orders. Printed receipts and local custom override the calculator for real-world tipping decisions.
