The sequence of reductions a product will receive is generally set during buying, long before its first day on sale. The plan is an input to the purchase, not a reaction to poor performance.

The buy is planned against a blended price

A buyer does not expect every unit to sell at full price. The quantity ordered assumes a proportion will sell at each successive discount level.

That blended average determines the margin the range will deliver, and the margin determines how much can be committed to the order in the first place.

Without an assumed markdown profile, the order quantity cannot be calculated, because there is no way to convert expected units into expected money.

Season length dictates the schedule

Seasonal goods have a fixed window in which they can be sold at all, and the number of weeks remaining is what governs how quickly prices must fall.

A product entering its final weeks with substantial stock left has no time for a gradual decline, so the schedule builds in deeper cuts toward the end of the window.

Categories without a seasonal ending, such as basic household goods, have much flatter schedules because there is no date after which the stock becomes unsellable.

Deviation from plan is the actual signal

The plan matters less as a prediction than as a benchmark. Weekly sales are compared against the expected rate, and the difference triggers action.

Selling ahead of plan means the first markdown can be delayed or skipped, which lifts margin. Selling behind means bringing it forward, which protects against a deeper cut later.

These decisions are usually made on a fixed weekly cycle rather than continuously, which is why price changes on the same range tend to appear together.

Early cuts are cheaper than late ones

A shallow reduction applied while most of the stock is still on hand can clear more units than a deep reduction applied when little time remains.

Delaying in the hope that demand recovers is the common error, because the eventual discount has to be larger and applies to a similar quantity of stock.

Retailers therefore build discipline into the timing rather than leaving it to judgement, since the incentive to wait is strong and usually wrong.

The plan shapes what shoppers see

Because schedules are set in advance and tied to season length, discount timing is far more predictable than it appears from outside.

Ranges introduced at the start of a season reach their first reduction at a fairly consistent point, and the pattern repeats each year for the same category.

What varies is depth rather than timing. How far a price falls depends on how the season went, but when it starts falling was decided before the stock was made.
