Discount Calculator

Fixed discount reduces the price by a specific amount (e.g., $10 off), giving equal savings regardless of the original price [citation:1][citation:8]. Percentage discount reduces the price by a percentage (e.g., 20% off), so larger items get more absolute savings [citation:1][citation:4].

• ✅ Example (Fixed): $50 item with $10 off → Final price = $40 (saves $10)
• ✅ Example (Percentage): $50 item with 20% off → Final price = $40 (saves $10)
• ✅ Fixed is better for: Small purchases where a fixed amount represents a larger percentage
• ✅ Percentage is better for: Large purchases where a percentage gives more savings

Formula: Final Price = Original Price − Fixed Discount, or Final Price = Original Price × (1 − Discount Percentage / 100) [citation:1][citation:4].

The random discount feature generates a random discount percentage or amount for each item. This can be useful for promotional purposes or creating excitement for customers [citation:2][citation:5].

• ✅ Random percentage: Generates a random percentage between a minimum and maximum range
• ✅ Random fixed amount: Generates a random currency amount between a minimum and maximum range
• ✅ Each item gets different discount: Every item processed receives its own unique discount
• ✅ Re-generate: Click the randomize button to get a new discount for each item

The random feature uses a cryptographically secure random number generator to ensure fairness [citation:5].

A calculation slip is a detailed receipt or summary of all your discount calculations. After calculating discounts for your items, you can generate a slip that includes [citation:12]:

• ✅ Item details: Product name, original price, discount type
• ✅ Discount applied: Fixed amount or percentage for each item
• ✅ Final price: The discounted price for each item
• ✅ Total savings: Total amount saved across all items
• ✅ Grand total: The total final price for all items

You can print the slip, save it as a Calculator, or copy it to your clipboard for record-keeping.

You can calculate discounts for multiple items in two ways [citation:4][citation:10]:

• ✅ Individual items: Add each item with its own price and discount
• ✅ Bulk calculation: Enter the total price of all items and apply a single discount
• ✅ Itemized slip: Each item is shown separately on the calculation slip
• ✅ Different discounts: Apply different discounts to different items

Example: Add three items with prices $100, $50, and $75, and apply 10%, 20%, and 15% discounts respectively. The calculator will show each item's final price and the total savings.

The Discount Calculator supports multiple currencies and automatically detects your region to display the appropriate currency symbol [citation:1][citation:4]:

• ✅ USD ($): United States
• ✅ INR (₹): India
• ✅ GBP (£): United Kingdom
• ✅ EUR (€): European Union
• ✅ Plus 10+ other currencies

You can manually select your currency if automatic detection is not available.
