How to Use the Tip Calculator
Enter Your Bill
Type the total bill amount in the dollar field on the home page. Use the pre-tax subtotal for a more traditional tip calculation.
Choose Tip Percentage
Select a preset (10%, 15%, 18%, 20%, 25%), use the slider, or type a custom percentage. The default is 15%.
Split the Bill (Optional)
Toggle "Split the bill" and set the number of people. The calculator will show how much each person pays for both the bill and tip.
Get Results
Click "Calculate Tip" to see tip amount, total bill, and per-person breakdown. Use the reset button to start a new calculation.

"Calculating..." doesn't finish
This usually means a network issue. Check your internet connection and try again. If the problem persists, try refreshing the page.
