How much should you tip at a restaurant?

Standard US tipping at sit-down restaurants: 15% for adequate service, 18–20% for good service, 20–25% for excellent service. At buffets, 10% is appropriate since service is minimal. At counter-service or fast casual, 10–15% is customary if prompted.

Do you tip before or after tax?

Tip on the pre-tax subtotal — tax money goes to the government, not the server. In practice, the difference is small (tipping on a $80 bill before 8% tax vs. after: $16 vs. $17.28), but tipping on the pre-tax amount is the technically correct standard.

How do you split a bill with a tip?

Enter the subtotal, choose your tip percentage, and enter the number of diners. Our calculator divides both the bill and tip evenly. For unequal splits (one person had more expensive items), calculate the tip on the full bill and then adjust per-person amounts manually.

What is the standard tip for food delivery?

For app-based food delivery (DoorDash, Uber Eats, Grubhub): $3–5 minimum, or 15–20% of order total, whichever is higher. For pizza delivery: $3–5 for orders under $30, 10–15% for larger orders. Delivery drivers often rely heavily on tips as base pay is low.

Should you tip at coffee shops?

Counter service at coffee shops: tipping is appreciated but not obligatory. 10–15% is generous for barista-made drinks. If you tip at your regular spot, baristas remember and often go the extra mile. No tip for plain drip coffee is generally acceptable; tip for elaborate espresso drinks.

What is included in tip at a restaurant?

Tips cover the server's income and are typically shared with bussers, food runners, and bartenders in a "tip pool." Tips are taxable income for servers. Some high-end restaurants add a mandatory service charge (18–20%) for large groups or instead of optional tipping — always check whether a gratuity has already been included before adding more.

You just finished dinner with friends and the bill arrives. Someone pulls out their phone to split the tip while everyone waits awkwardly. Sound familiar? A tip calculator should make this moment effortless — enter the bill, choose a percentage, split by the number of diners, and be done in 10 seconds.

Our free tip calculator handles all of this and more. Calculate the tip amount, total bill including tip, and the exact per-person share. Choose from standard percentages (15%, 18%, 20%) or set a custom amount. Works perfectly for restaurants, bars, taxi rides, hotel staff, food delivery, hair salons, and any service tip situation.

Why Tip Calculator Matters

Tipping is both a financial and social decision. In the United States, tips constitute the majority of income for servers, bartenders, and many service workers — the federal tipped minimum wage is just $2.13/hour, with tips expected to bring total pay to at least $7.25. Understanding tipping norms and calculating accurately ensures you're being fair to service workers while staying within your own budget.

The trend toward digital tip prompts (on tablets and point-of-sale systems) has increased tip percentages, with customers now routinely prompted for 18%, 20%, 22%, and even 25%. Knowing what you're selecting — and why — helps you tip intentionally rather than just pressing a button.

The Tip Calculator Formula, Explained

Tip Amount = Bill × (Tip % ÷ 100) | Per Person = (Bill + Tip) ÷ Number of People

To calculate a 20% tip on a $85 bill: Tip = $85 × 0.20 = $17. Total = $85 + $17 = $102. Per person (4 diners) = $102 ÷ 4 = $25.50. Mental math shortcut: 20% of any bill = move decimal left one place (10%) then double. $85 → $8.50 → $17.

Tip Calculator Examples: Real-World Scenarios

Restaurant Dinner for Four — 20% Tip

Four friends at a restaurant, total bill $148.60 before tax. They want to leave a 20% tip.

Bill subtotal:$148.60

Tip percentage:20%

Number of diners:4

Calculation

Tip: $148.60 × 0.20 = $29.72 | Total: $148.60 + $29.72 = $178.32 | Per person: $178.32 ÷ 4

Result

Each person owes $44.58. Tip total: $29.72 (split evenly means each contributes $7.43 in tip).

Rideshare Tip — $1 vs Percentage Debate

A $12.50 Uber ride. Rider is deciding between a $2 flat tip and a 15% percentage tip.

Ride cost:$12.50

Option A:$2 flat

Option B:15%

Calculation

Option A: $2 flat (16% effective) | Option B: $12.50 × 0.15 = $1.88

Result

$2 flat is actually slightly more than 15%. For short rides (under $15), a $1–2 flat tip is generous. For longer rides ($25+), 15–20% is the appropriate benchmark.

Hair Salon — Tipping on Service Only

A hair color service costs $180. The client wants to tip 20% on the service but not the product markup.

Service only cost:$150

Product/materials:$30

Tip rate:20%

Calculation

20% of $150 service = $30 tip

Result

Tip: $30. Total paid: $210. Note: industry standard is to tip on the service portion, not on products or retail items.

Common Mistakes to Avoid

Tipping on the post-tax total — tip should be calculated on the pre-tax subtotal, as tax is paid to the government, not the server.
Applying restaurant tip rates to all services — hotel housekeeping ($3–5/night), valet ($2–5), coat check ($1–2 per coat), and bellhops ($1–2 per bag have their own norms.
Splitting the bill equally when orders were unequal — the split feature shows per-person amounts for equal splitting; if orders varied, adjust accordingly.

Tips & Tricks

Mental math quick tip: for 15%, find 10% (move decimal), then add half. For a $64 bill: 10% = $6.40, half = $3.20, 15% = $9.60.
In the US, tipping is discretionary but expected in sit-down restaurants. For counter service, coffee shops, and fast casual, 10–15% is customary when a tip option is presented.

A well-calculated tip is a small act of fairness that matters significantly to service workers. Our tip calculator makes it effortless — calculate in seconds and split the bill precisely so every dining experience ends smoothly.
