HOW TO USE

  1. 1

    Select your mode: Percentage off (you know the % discount), Fixed amount off (you know the dollar saving), or Find discount % (you know both the original and sale price).

  2. 2

    Enter your two primary values. For stacked discounts, enter the second percentage in the Stack a 2nd Discount field — it applies to the already-discounted price.

  3. 3

    Optionally add a flat coupon or voucher amount. This is deducted after all percentage discounts — consistent with standard retail practice.

  4. 4

    The result shows the final price, total saving, and effective discount percentage — the true combined saving as a share of the original price.

  5. 5

    Review the reference table to see the sale price and saving at every common discount level (5% to 75%) applied to your original price.

WORKED EXAMPLE

Example 1 (% off): $120 with 25% off. Discount = $30. Sale price = $90. Example 2 (fixed off): $120 with $20 off. Discount = 16.67%. Sale price = $100. Example 3 (stacked): $120, 20% off ($96), then 10% off ($86.40). Effective = 28% (not 30%). Example 4 (with coupon): $120, 25% off ($90), then $10 coupon = $80. Effective = 33.33%.
