Quick Tips for Everyday Calculations

Standard Tipping Guidelines

15% for acceptable service, 18-20% for good to great service, and 20-25% for exceptional service. For quick math, calculate 10% (move decimal) and add half for 15%, or double for 20%.

Splitting Bills Fairly

When splitting a bill, always calculate the tip on the total before dividing. This ensures the server gets a fair tip. For uneven orders, consider apps or calculators that track individual items.

When to Tip More

Consider tipping above 20% for large groups, complicated orders, exceptional service, or during holidays. Bartenders typically receive $1-2 per drink or 15-20% of the tab.

Tipping on Takeout

Tipping on takeout is optional but appreciated. 10% is courteous for takeout; 15-20% for delivery. Consider tipping more during busy times or for large, complex orders.

Frequently Asked Questions

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

While both are acceptable, tipping on the pre-tax amount (subtotal) is more common. However, many people tip on the total for simplicity. The difference is usually small, so choose what's convenient for you.

How do I quickly calculate a 20% tip?

The easiest method: move the decimal one place left (that's 10%), then double it. For a $47.80 bill: 10% = $4.78, doubled = $9.56 for a 20% tip. Round to $9.50 or $10 for convenience.

What if the service was poor?

For genuinely poor service, 10-12% is acceptable. However, consider whether issues were the server's fault or kitchen/management problems. Speak with a manager about serious issues rather than reducing the tip significantly.

Are tips included for large groups?

Many restaurants automatically add an 18-20% gratuity for parties of 6 or more. Always check your bill for "gratuity included" before adding an additional tip. You can add more if service was exceptional.
