Discount Calculator

What is Discount Calculator?

Shopping sales, promotional clearance events, and retail pricing strategies often involve percentage markdowns and stacked discount coupons. Our Discount Calculator computes the final sale price, total dollar savings, and combined effective discount percentage, alongside a reverse discount mode that calculates the original pre-sale price from a discounted total.

Designed for accuracy, speed, and privacy, this tool runs entirely on your local device with zero network latency.

How to Use the Discount Calculator

1. 1
   Select your calculation mode: "Standard Discount" (with optional stacked coupons) or "Reverse Discount".
2. 2
   Enter the Original Item Price and the Primary Discount Percentage (%).
3. 3
   Optionally add a Second Discount Percentage (e.g., an extra 15% promotional store coupon).
4. 4
   Review the final discounted price, total cash savings, and effective total discount rate.

Formula & Calculation Logic

Calculates consecutive multiplicative percentage reductions. Stacked discounts apply sequentially to the already-discounted intermediate subtotal rather than adding percentages linearly.
