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

Tipping on the pre-tax subtotal is the standard practice. The tax portion goes to the government, not the service provider. However, tipping on the post-tax amount is also acceptable and slightly more generous.

How much should I tip for delivery?

A good rule is 15-20% of the order total or a minimum of $3-5, whichever is higher. For long-distance deliveries or bad weather, consider tipping more to compensate the driver.

Is it rude to use a tip calculator?

Not at all. Using a tip calculator ensures accuracy and fairness, especially when splitting a bill among several people. It is far better than guessing and accidentally under-tipping.

Standard Tipping Percentages

15% – acceptable for average service at a sit-down restaurant.
18% – standard tip for good service in the United States.
20% – generous tip for excellent service or fine dining.
25%+ – exceptional service or to show extra appreciation.
10% – common for takeout orders or counter service.

How the Tip Formula Works

The tip formula is straightforward: Tip Amount = Bill Total x (Tip Percentage / 100). For a $65 dinner with an 18% tip, the calculation is $65 x 0.18 = $11.70, making the total $76.70. If you want to split the tip between multiple people, divide the tip amount by the number of people at the table.

Step-by-Step Example

Start with the pre-tax bill

Use the subtotal before tax. Tipping on the pre-tax amount is the most common practice.

Pick your tip percentage

Choose 15%, 18%, 20%, or enter a custom amount based on the quality of service.

Multiply and add

Multiply the bill by the tip percentage as a decimal. Add the result to your bill for the grand total.

Split if needed

Divide the total (bill plus tip) by the number of people to find each person's share.

When to Tip More or Less

Consider tipping above 20% for large parties, complicated orders, or when a server goes above and beyond. For delivery drivers, a minimum of $3-5 or 15-20% of the order is customary. At coffee shops and fast-casual restaurants, tips are appreciated but typically optional. Toolin's tip calculator lets you adjust the percentage and number of people to see totals instantly.
