On a $250.00 retail purchase, stacking 20% off with an extra 10% off brings the final price to $180.00, an effective 28% discount (not 30%). Comparing unit prices, Item B (Bulk) is 16.6% cheaper per unit ($0.39 vs. $0.47).

Formula & Mathematical Methodology: Salary Raise Escalation, Multiplicative Stacked Discount & Unit Cost

Paynew = Payold × (1 + Raise%100),   Pricesale = Plist(1 − d1)(1 − d2),   Unit Cost = PriceQuantity
Pay_new = Pay_old × (1 + Raise%); Price_sale = P_list × (1 − d_1) × (1 − d_2); UnitCost = Price / Quantity
  • d1, d_2: First and second fractional discounts applied sequentially
  • 1 − (1−d1)(1−d_2): True effective combined discount (e.g., 20% + 10% stacked = 28% off, not 30%)

Rounding: Currency rounds to 2 decimal places; unit prices round to 3 decimal places.

Worked Example: 8% Raise on $75,000 Salary + 20% & 10% Stacked Discount on $250 Item

Compute new annual/hourly pay after an 8% raise and the final price of a $250 jacket with 20% off plus an extra 10% coupon.

  1. 8% raise adds $75,000 × 0.08 = +$6,000/yr (+$500/mo or +$2.88/hr) → New salary = $81,000/yr ($38.94/hr).
  2. First 20% discount reduces $250 to $200.00; extra 10% off reduces $200.00 to $180.00 ($70 saved = 28.0% effective discount).
  3. Unit price: Item A ($14.99 ÷ 32 oz = $0.468/oz) vs. Item B ($24.99 ÷ 64 oz = $0.390/oz) → Item B saves 16.7%.
Result: New salary is $81,000/yr ($38.94/hr), sale price is $180.00 (28% effective off), and Item B saves 16.7% per unit.

Frequently Asked Questions

Why is 20% off plus an extra 10% off equal to 28% off instead of 30% off?

Because the second 10% discount is applied to the already-reduced sale price (80% of original), not the original tag price: 0.80 × 0.90 = 0.72 (72% paid, or 28% total discount).

How do I compare unit prices when one package is listed in ounces and another in pounds?

Convert both packages to the same unit first (1 pound = 16 avoirdupois ounces; 1 kilogram = 1,000 grams; 1 liter = 1,000 milliliters) before dividing price by quantity.
