1. What is the Tip and Tax Calculator?

This calculator helps you determine the total cost of a purchase including tax and tip. It calculates the additional amounts for tax and tip based on your input values and provides the final total amount you'll need to pay.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( amount \) — Original amount before tax and tip
• \( tax\ rate \) — Percentage of tax (e.g., 8.25 for 8.25%)
• \( tip\ rate \) — Percentage of tip (e.g., 15 for 15%)

Explanation: The calculator first converts the percentage rates to decimal values, then calculates the tax and tip amounts separately before adding them to the original amount.

3. Importance of Calculating Tip and Tax

Details: Knowing how to calculate tax and tip helps with budgeting, ensures you leave appropriate gratuity, and helps avoid surprises when receiving the final bill.

4. Using the Calculator

Tips: Enter the original amount before tax, then enter the tax rate and tip rate as percentages (e.g., 8.25 for 8.25%). All values must be positive numbers.
