Build a markdown ladder by capturing the original price, choosing a sequence of meaningful non-compounding discounts, defining how long each step will be observed, and setting a sales goal, maximum discount, minimum effective price, and end behavior. Calculate every step from the captured original—not from the previous reduced price.
The anatomy of a controlled ladder
A markdown ladder is a pre-approved sequence of sale prices. It creates structured opportunities to stop before reaching the deepest discount.
Every ladder needs seven elements:
- Captured original price — the reference for every calculation.
- Step percentages or target prices — the allowed reductions.
- Observation window — how long or how much traffic each step needs.
- Business goal — what success means.
- Price floor — the lowest acceptable effective sale price.
- Discount cap — the deepest permitted reduction.
- End behavior — hold the working price or restore the original.
Use non-compounding steps
Assume the captured original price is $100 and the ladder is 10%, 15%, and 20%.
| Step | Calculation | Sale price |
|---|---|---|
| 1 | $100 × (1 − 0.10) | $90 |
| 2 | $100 × (1 − 0.15) | $85 |
| 3 | $100 × (1 − 0.20) | $80 |
Do not apply 15% to the already reduced $90 unless you intentionally designed a compounding campaign. Compounding makes the effective discount harder to understand and can cross a price boundary unexpectedly.
Choose steps that can change a decision
A step should be commercially meaningful for the product and easy for the customer to understand. A one-point change may be too small to learn from; a twenty-point jump may sacrifice the opportunity to find a shallower working price.
Price endings or rounding can change the exact effective percentage. Always validate the resulting money price after rounding rather than assuming the nominal percentage tells the whole story.
Define evidence before escalation
A calendar interval is necessary but not always sufficient. If a product received almost no qualified traffic, the absence of sales does not strongly distinguish price resistance from lack of exposure.
Pair time with available evidence where possible:
- minimum observation days;
- relevant product views or sessions;
- units sold during the step;
- recent pace compared with the campaign goal.
Guard the realized price
The floor check belongs immediately before each write because other conditions can change. Cost data, current price, active campaigns, or merchant edits may differ from what was true at campaign creation.
If a product participates in checkout promotions, evaluate the possible realized customer price as part of campaign planning. A safe stored sale price can become unsafe when another discount also applies.
Example stopping rule
“Sell 12 units by September 15. Review every 14 days. Stop as soon as 12 units sell. Do not exceed 25% off or go below $58. At completion, hold the working price for manual review.”
That sentence is far more operationally useful than “discount until sales improve.”
Frequently asked questions
Should markdown steps compound?
For an understandable controlled ladder, calculate every step from the captured original price. This makes the maximum effective discount explicit and easier to audit.
Can I use fixed target prices instead of percentages?
Yes, provided each target is validated against the original, floor, currency, and campaign cap. Fixed prices can be easier when merchandising requires exact price points.
What happens if I manually change the product price?
A safe automated campaign should pause and ask for review rather than overwriting a new merchant decision or restoring an outdated original blindly.
