Overview
The Discount Calculator helps you estimate final payable price from original price and discount rate, supports markdown conversion, and allows extra deduction stacking for real-world promotion scenarios.
Key Features

How To Use
- Enter the original price.
- Enter a discount rate, or input markdown directly.
- Add extra deduction if a coupon or fixed reduction applies.
- Read final price, savings amount, and effective discount rate.
Formula
- Discount amount = original price x discount rate / 100
- Total deduction = discount amount + extra deduction
- Final price = max(0, original price - total deduction)
- Effective discount rate = (original price - final price) / original price x 100%
FAQ
- What does 8.0 markdown mean? It means paying 80% of the original price, which equals a 20% discount rate.
- Why can effective discount rate be higher than input discount rate? Extra deduction further reduces final payable price.
