割引や追加の節約後の最終価格を計算します。
We all love a good bargain, but retail math can be tricky, especially when multiple discounts are involved. Does a '30% off' sale followed by an 'extra 10% off' coupon mean 40% off? (Spoiler: No). Understanding the actual final price before you head to the checkout helps you stick to your budget and identify the best deals. Our Discount Calculator allows you to input the original price and apply both primary and additional discounts to see your final cost and total dollar savings instantly.
使い方
The tool first calculates the price after the primary discount. If an additional discount is provided, it applies that percentage to the new subtotal. It then subtracts the final price from the original price to show your total savings.
計算式
Final = Original × (1 - Disc1) × (1 - Disc2)
Calculation Examples
1. **Single Discount**: A $60 shirt at 25% off costs **$45**.
2. **Stacked Discount**: A $100 item with 20% off and an extra 10% coupon costs **$72** (Total savings: $28).
