Enter your bill, choose a tip, and split. Round up or down to a clean total when you're done.
The formula for a tip is simple: multiply your bill by the tip percentage expressed as a decimal. A 20% tip on a $45 bill is $45 × 0.20 = $9.00. Doing that math quickly at a restaurant table, especially after a few drinks, is where things go sideways. Here are three mental math shortcuts that actually work.
Start by finding 10% of your bill. Just move the decimal point one place to the left. From there, you can build any tip:
In most US states, sales tax runs between 6% and 10%. If your tax is shown on the receipt, doubling it gives you a rough 12 to 20% tip depending on your state's rate. It is not precise, but it is fast, and it is always been calculated for you on the bill already.
Tipping on the pre-tax subtotal is the traditional standard. The tip is meant to reflect the service on the food and drink, not the tax. Tipping on the total (including tax) has become common and completely acceptable. The difference on a $50 meal in a state with 8% tax is about $0.80. It is not going to make or break anyone. Either way is fine. The calculator above lets you choose.

Tipping norms vary significantly by industry, situation, and even geography. These are the widely accepted US standards as of 2026. Not rules, but reasonable starting points.
| Service | Standard Range | Notes |
|---|---|---|
| Restaurant (sit-down) | 18–20% | 15% for adequate service; 20%+ for excellent. Tip on pre-tax subtotal is traditional, but tipping on total is accepted. |
| Restaurant (buffet) | 10% | Optional but appreciated. Staff still clears plates and refills drinks. |
| Bar / bartender | $1–2/drink or 15–20% of tab | Per-drink tipping is common for simple orders. Percentage tip preferred for cocktail service. |
| Food delivery (app-based) | 15–20% or $3–5 minimum | Higher percentage on small orders. Drivers cover their own gas and expenses. |
| Pizza delivery | $3–5 or 15% | Minimum $3 regardless of order size. More in bad weather or for long distances. |
| Taxi / rideshare | 15–20% | App prompts often suggest 20–25%. 15% is perfectly acceptable for standard service. |
| Hair salon / barber | 15–20% | Tip the stylist directly, even if the salon owner cuts your hair. Assistants who shampoo appreciate $2–5. |
| Nail salon | 15–20% | Standard for manicures and pedicures. Round up for extra services. |
| Massage therapist | 15–20% | Standard at spas or for independent therapists. Not always expected at medical massage clinics. |
| Hotel housekeeping | $2–5/night | Leave daily, not just at checkout. Different staff may clean your room each day. |
| Hotel valet | $2–5 | Tip when your car is returned, not when you drop it off. |
| Hotel concierge | $5–20 | $5 for simple requests. $10–20 for hard-to-get reservations or special arrangements. |
| Airport / hotel bellhop | $1–2/bag | Minimum $2–3 for the trip regardless of bag count. |
| Food truck | 10–15% | Optional but increasingly appreciated. Tip jars are common. |
| Coffee shop / café counter | $0.50–1 or 10% | Discretionary. Drip coffee is optional. Complex espresso drinks more common to tip on. |
| Takeout / counter service | 0–10% | Fully discretionary. Tip screens have normalized 15–20% prompts, but there is no obligation. |
| Tour guide | $5–10/person (group); $10–20 (private) | Tip at the end of the tour if satisfied. More for in-depth, exceptional, or private tours. |
| Movers | $20–50/person | For a full-day move. More for heavy or complex moves, stairs, or extreme weather. |
| Tattoo artist | 15–20% | Tip in cash when possible. For multi-session pieces, tip per session. |
| Spa services (facial, wax) | 15–20% | Same standard as hair and nail services. |
| Dog groomer | 15–20% | Especially for difficult or large dogs, or extra services. |
| Parking attendant (valet) | $2–5 | Tip on car pickup. Not required, but appreciated. |
Since the pandemic, tablet tip prompts have appeared at coffee shops, takeout counters, food trucks, smoothie bars, and anywhere a point-of-sale system sits. The prompts often suggest 18%, 20%, and 25%, or in some cases offer only those options with a small "Custom" or "No tip" button that can feel deliberately uncomfortable to tap.
Here's the honest answer: there is no social obligation to tip at counter service where you order and pick up your own food, carry your own tray, and never interact with a server. Tipping in these settings is entirely discretionary. The discomfort you feel is a design feature of the prompt, not a reflection of any actual norm or obligation.
Bottom line: press "No tip" or "Custom" and enter $0 without guilt when the situation genuinely doesn't warrant it. Tipping is meant to reflect service, not to compensate for uncomfortable UX design.
A 20% tip on a $50 bill is $10.00, making the total $60.00. To calculate quickly: move the decimal one place left to get 10% ($5.00), then double it for 20% ($10.00).
A 20% tip on a $100 bill is $20.00, for a total of $120.00. On round numbers like $100, 20% is simply one-fifth of the total.
To calculate an 18% tip, find 10% of your bill (move the decimal left), then add 8% (roughly 80% of the 10% value). On a $60 bill: 10% = $6.00, 8% = $4.80, total tip = $10.80. Or just use the calculator above.
15% was the traditional standard for adequate service at a sit-down restaurant. Today, 18 to 20% is more commonly expected for standard service, with 20%+ for excellent service.
15% is still acceptable, particularly for basic service, but tipped workers' base wages have not kept pace with inflation, so many etiquette experts now suggest 18 to 20% as the new baseline.
Divide the total bill (including tip) by the number of people splitting. The calculator above does this automatically.
For example: a $120 bill with a 20% tip is $144 total ÷ 4 people = $36 per person.
Traditionally, tipping on the pre-tax subtotal is standard. The tip is meant to reflect the service on food and drink, not on the tax itself. Tipping on the total (including tax) is also widely accepted and common.
The practical difference is small. On a $50 meal with 8% tax, tipping 20% pre-tax is $10.00; tipping 20% on the total is $10.80.
In the US, not tipping at a sit-down restaurant is considered rude and leaves servers significantly underpaid. Tipped employees are legally paid a lower minimum wage ($2.13/hour federally, though many states are higher) with the expectation that tips make up the difference.
If you had a bad experience, tipping less (10 to 15%) is acceptable. Not tipping at all is generally reserved for genuinely egregious service failures.
15 to 20% of the order total is standard for app-based food delivery, with a minimum of $3 to $5 regardless of order size. Delivery drivers cover their own vehicle expenses.
Tip more in bad weather, for long distances, or for large orders.
Tipping at a coffee shop is discretionary, not obligatory. For complex espresso drinks or if you're a regular with a relationship with the staff, a small tip is appreciated.
For simple drip coffee at a counter, there is no obligation. The tip screen prompt you see is a feature of the POS system, not a social requirement.
15 to 20% is standard for hair services. Tip the stylist directly in cash when possible, as some salons take a percentage of card tips.
If an assistant shampoos your hair, a separate $2 to $5 tip for them is a nice gesture.
We built the Tip Calculator because nobody wants to do mental math after a few drinks at a restaurant table. It does the percentage, the split, and the round-up to a clean total. The full tipping guide below is something we wanted ourselves: a single, reasonable answer for what to tip across every service we've actually used. This site is a part of the ads4good Network.
