Quick Start
Using HeronTool's Discount tool is a three-step process:
- Enter the original price (e.g., $200).
- Enter the discount rate (e.g., 20% off, or 80% as the paid percentage).
- Click "Calculate" to instantly see the final price and savings.
Advanced Usage
- Multiple items: Calculate each separately and sum, or use the batch mode if available.
- Reverse calculation: If you know the final price and discount rate, reverse-engineer the original price for bill verification.
- Compare offers: Use the tool to see whether a flat discount or a percentage off gives a better deal.
