Successive Discounts

Retailers often apply multiple discounts in a row, such as a promotional sale discount followed by a loyalty card discount. These are calculated step-by-step, not by simply adding the percentages together.

Fundamental Principles

Successive Deductions

A pricing system where a second discount percentage is applied directly to the lower price left after the first discount.

Single Equivalent Discount

A single overall discount percentage that matches the final price reduction of a series of separate discounts.

Essential Formulation Tips

  • Never just add successive discounts together (for example, a 20% discount followed by a 10% discount is not a 30% discount).
  • The order of the discounts does not matter; applying 20% then 10% gives the same final price as applying 10% then 20%.

Shortcut Execution Techniques

  • For two successive discounts of x% and y%, use this formula to find the single equivalent discount: Total Discount = x + y - (x * y / 100).

Contextual Inquiries (FAQs)

Q: Why is the total discount lower than adding the percentages together?

A: Because the second discount is calculated from a smaller, already reduced price rather than the original starting price.
