1. What is the Grocery Tax Calculator?

The Grocery Tax Calculator computes the total cost of groceries including tax based on the subtotal and local tax rate. It helps shoppers budget accurately for their grocery purchases.

2. How Does the Calculator Work?

The calculator uses the simple tax formula:

Where:

• \( Subtotal \) — Cost before tax (USD)
• \( Tax rate \) — Local sales tax rate (decimal)

Explanation: The tax rate is added to 1 to get the multiplier, which is then applied to the subtotal to calculate the final amount.

3. Importance of Tax Calculation

Details: Accurate tax calculation ensures you know the exact amount you'll pay at checkout, helping with budgeting and avoiding surprises at the register.

4. Using the Calculator

Tips: Enter subtotal in USD and tax rate as a decimal (e.g., 0.08 for 8%). Both values must be positive numbers.
