What is the Standard Tip Rate?
Tipping etiquette varies by country, but in the United States and Canada, a gratuity of 15% to 20% of the pre-tax bill is standard for sit-down dining.
Calculating this quickly while the waiter waits can be stressful. Our AI-powered calculator does the heavy lifting, ensuring you are generous enough to the staff without overpaying by mistake.
How to Calculate Tip Manually?
If you don't have this tool handy, here is the basic formula used by our system:
Bill Amount × (Tip Percentage / 100)
Example: $100 × 0.15 = $15.00
Bill Amount + Tip Amount
Example: $100 + $15 = $115.00
When splitting the bill, simple division often results in repeating decimals (e.g., $33.333...). Our algorithm detects this and recommends using the "Round Up Per Person" feature to ensure the total collected covers the entire bill plus a small extra buffer for the server.

Frequently Asked Questions
Should I tip on the pre-tax or post-tax amount?
Etiquette dictates you should calculate the tip based on the pre-tax subtotal. Tipping on the tax means you are giving a tip to the government, though doing so is generous and often easier to calculate.
Does this calculator handle bill splitting?
Yes. Enter the number of people in your party, and the calculator divides the Total (Bill + Tip) evenly. Use the rounding feature to make it easier for everyone to pay cash or transfer money.
