Receipt Calculator
This calculator helps you quickly tally up the cost of multiple items, apply a sales tax, and generate a simple receipt-like summary. It's perfect for small businesses, personal budgeting, or estimating shopping costs before checkout.
How the Receipt Calculator Works
This tool takes individual item details—name, unit price, and quantity—along with a sales tax rate, to compute a comprehensive total. It then presents these details in an easy-to-read receipt format.
Input Fields Explained:
- Item Name: A descriptive name for each product or service.
- Item Unit Price ($): The cost of a single unit of the item.
- Item Quantity: The number of units purchased for that specific item.
- Sales Tax Rate (%): The percentage of sales tax to be applied to the subtotal of all items.
Output Explained:
The calculator generates a detailed receipt including:
- Individual Item Lines: Shows the item name, unit price, quantity, and the total cost for that item (Unit Price x Quantity).
- Subtotal: The sum of all individual item totals before tax.
- Sales Tax: The calculated amount of tax based on the subtotal and the entered sales tax rate.
- Grand Total: The final amount, which is the subtotal plus the sales tax.
Example Calculation:
Let's use the default values provided in the calculator:
- Item 1: Coffee Mug, Unit Price: $12.50, Quantity: 2
- Item 2: Notebook, Unit Price: $5.00, Quantity: 3
- Item 3: Pen Set, Unit Price: $8.75, Quantity: 1
- Sales Tax Rate: 7.5%
Step 1: Calculate individual item totals:
- Coffee Mug: $12.50 x 2 = $25.00
- Notebook: $5.00 x 3 = $15.00
- Pen Set: $8.75 x 1 = $8.75
Step 2: Calculate the Subtotal:
- Subtotal = $25.00 + $15.00 + $8.75 = $48.75
Step 3: Calculate Sales Tax:
- Sales Tax = $48.75 x (7.5 / 100) = $3.65625 (rounded to $3.66)
Step 4: Calculate the Grand Total:
- Grand Total = $48.75 + $3.66 = $52.41
The receipt will display these values clearly, providing a complete breakdown of the transaction.
