Stockout Cost Calculator
What does running out of a bestseller actually cost, in lost revenue and lasting algorithm damage?
About this tool
Stockouts cost more than the missed orders. They drop your Google Shopping impression share, kill Meta CBO learning, and customer trust takes weeks to rebuild even after restock. This tool estimates direct lost revenue, ad-channel learning loss, and SEO velocity impact.
The hidden tax: algorithm recovery
A stocked-out SKU loses its position in PMax and Meta Advantage+ ranking immediately. When you restock, the campaigns have to relearn what conversion looks like for that SKU at the new traffic profile. For 7+ day stockouts, expect 2–4 weeks of degraded efficiency before ROAS returns to baseline. This is often 2–3× the direct revenue loss.
Damage control during stockout
- • Pause paid traffic to the SKU (don't pay for clicks they can't buy)
- • Set
availabilitytoout_of_stockin your feed so Google de-prioritises rather than disapproves - • Switch the PDP to a back-in-stock email capture (preserves intent)
- • Redirect retargeting audiences to a related in-stock SKU
- • Stagger the restock launch — slow ramp of paid spend over 1–2 weeks
