1. What is the Tax and Gratuity Calculator?

The Tax and Gratuity Calculator helps you determine the total amount to pay by adding the original bill amount, tax, and gratuity (tip) percentage. It's useful for restaurants, hospitality services, and personal finance management.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Bill \) — Original amount before taxes and tip (USD)
• \( Tax \) — Tax amount (USD)
• \( Gratuity \) — Tip percentage (as decimal)

Explanation: The calculator adds the base bill, fixed tax amount, and calculates the gratuity as a percentage of the original bill.

3. Importance of Accurate Calculation

Details: Proper calculation ensures you pay the correct amount, helps with budgeting, and ensures fair compensation for service staff.

4. Using the Calculator

Tips: Enter bill amount in USD, tax amount in USD, and gratuity as a percentage (e.g., 15 for 15%). All values must be positive numbers.
