Work backwards from the total paid to find the original bill and tip amount.
Know the total you paid? Enter it below to find the original pre-tip bill and how much was tipped.
Enter the total paid + tip percentage to find the original bill amount.
Use this to verify the tip was correctly applied on your receipt.
Works for any tipping situation — restaurant, delivery, Uber, haircut.
Formula: Original Bill = Total ÷ (1 + Tip% ÷ 100)
Use it when you see a total on your credit card statement and want to know the original bill and tip amount. Also useful for expense reports where you need to separate the tip from the total.
Original Bill = Total Paid ÷ (1 + Tip Percentage ÷ 100). Example: You paid $118 total with an 18% tip. Original bill = $118 ÷ 1.18 = $100. Tip = $118 - $100 = $18.
If a restaurant calculates a tip automatically (for large groups), use this calculator to verify the math is correct and you haven't been overcharged.
