It is a universal modern anxiety: The cashier swivels the iPad around, and you are faced with three buttons—18%, 20%, 25%. The barista is watching. The line behind you is waiting. Do you tip for a black coffee? If so, how much?
Tipping culture has shifted dramatically in recent years. What was once a reward for exceptional service has increasingly become an expectation, even for counter service. This phenomenon, known as “Tipflation,” has left many consumers confused about what is actually fair.
Furthermore, the math itself can be tricky. Should you tip on the tax? How do you split a bill among 7 people with different drink orders? In this comprehensive guide, we will break down the rules of modern etiquette, the math tricks to calculate quickly, and when it is okay to tap “No Tip.”

1. The New Standard: 15% vs. 20%
For decades, 15% was the gold standard for “good service” in North America. However, with inflation and the rise of digital payment terminals, the baseline has shifted.
- 15% – Minimum / Okay: This is now considered the baseline for standard, adequate service.
- 18% – Good Service: This has become the new “Standard” for a pleasant dining experience.
- 20-25% – Excellent: Reserved for servers who go above and beyond, or for fine dining establishments.
- 10% or Less – Poor: Generally seen as a statement of dissatisfaction. However, many etiquette experts suggest speaking to a manager rather than leaving a bad tip, as the tip often gets shared with kitchen staff who weren’t at fault.
2. The “Pre-Tax” vs. “Post-Tax” Debate
This is the most common mathematical error in tipping, and payment terminals use it to their advantage.
Standard Etiquette Rule: You should calculate the tip on the Subtotal (Pre-Tax amount), not the Total.
Why? Because the tax is a government fee, not a service provided by the restaurant. Tipping on the tax means you are essentially tipping the government.
The Problem: Most credit card machines calculate their preset percentage buttons (18%, 20%, 25%) based on the Total (Post-Tax) amount. This means if you click the “20%” button, you are actually tipping closer to 22-23% of the meal cost.
Calculate the Exact Amount
Stop overpaying. Input your bill subtotal to see exactly what a fair 15%, 18%, or 20% tip looks like without the “Tax on Tax” markup.

Not every service requires a gratuity. Use this quick reference table to navigate daily life without overspending.
| Service | Expected Tip | Notes |
|---|---|---|
| Sit-Down Dining | 18% – 20% | Servers rely on tips as their primary income (sub-minimum wage laws). |
| Barista / Coffee | $1 or 10-15% | Optional. Nice for complex orders (lattes), unnecessary for drip coffee. |
| Food Delivery | 10% – 15% | Minimum $3–$5. Higher during bad weather. |
| Rideshare (Uber/Lyft) | 10% – 20% | Depends on car cleanliness and driving safety. |
| Hair / Salon / Spa | 15% – 20% | Standard for personal care services. |
| Takeout / Pickup | 0% – 10% | Optional. You are doing the “service” of picking it up. |
| Contractors (Plumber) | $0 (None) | Professional trades charge high hourly rates; tips are not expected. |
4. International Etiquette (Where NOT to Tip)
Tipping is a distinctively North American habit. In many parts of the world, leaving cash on the table is confusing or even offensive.
Europe (France, Italy, UK)
Service is usually included (“Service Compris”). Locals might leave the small change or round up the bill (e.g., €47 to €50), but a full 20% tip marks you instantly as a tourist.
Japan & South Korea
Do Not Tip. Good service is considered a standard duty, not an extra. Leaving money can be seen as an insult, implying the employer does not pay their staff well. Servers have been known to chase customers down the street to return “forgotten” change.
Australia & New Zealand
Wages are high, and tipping is not expected. It is appreciated for exceptional service but never mandatory.
5. Mental Math Hacks
If you don’t have our calculator handy, here are three mental tricks to find the number quickly.
The 10% Method (The Easiest)
Simply move the decimal point one spot to the left.
Bill: $45.00 → 10% is $4.50.
- For 20%: Double that number ($4.50 x 2 = $9.00).
- For 15%: Take the 10% number ($4.50) and add half ($2.25). Total = $6.75.
The “Double Tax” Method (Certain States)
If you live in a place where sales tax is roughly 8-10% (like NYC, California, or Seattle), you can simply look at the tax line on the receipt and double it to get a ~18-20% tip.
6. Handling the “Split Bill” Nightmare
The end of a dinner with friends often turns into a chaotic math exam. One person had water; another had three cocktails. Do you split evenly?
Etiquette Rules:
- Even Split: Acceptable if everyone ordered roughly the same price items (e.g., everyone got an entree and a drink). It saves time and stress.
- Itemized Split: Mandatory if there is a huge discrepancy (e.g., one person ordered steak and wine, another ordered a salad). Don’t force the salad eater to subsidize the steak.
Calculating an itemized split manually—adding tax and tip to individual items—is prone to error. Using a digital Bill Splitter ensures fairness and prevents the server from being short-changed.
Conclusion
Tipping doesn’t have to be stressful. By knowing the standard percentages (15-20% for table service) and calculating based on the pre-tax subtotal, you can feel confident when the bill arrives.
Remember: Tipping is ultimately about gratitude. While math helps, generosity is usually the better policy when in doubt.
