Seasonality
Peak-day outages don't scale linearly.
A generic annual average hides the number that matters most: what does an outage cost on your highest-traffic day, when the marginal revenue per hour can be many times the yearly average?
Change freeze tradeoff
Many retailers freeze deployments during peak season specifically to avoid self-inflicted outages when the cost curve is steepest.
Traffic surge fragility
Peak-season traffic itself increases incident frequency for capacity-related failures, compounding the cost multiplier rather than just the revenue rate.
FAQ
Ecommerce outage cost, answered.
Questions that come up when sizing the cost of a storefront outage.
How much more does a peak-day outage cost?
Scale the revenue impact input to your peak-hour sales rate rather than your annual average — for many retailers this is 5 to 10 times higher during major sale events.
Should cart abandonment be modeled separately?
It's already implicit in the revenue impact figure if that number reflects actual checkout revenue per hour — no need to double-count it as a separate line item.
Does this cover the cost of website downtime broadly?
This page focuses on ecommerce transaction revenue specifically. See cost of website downtime for the broader SEO and trust angle.
What SLA target is realistic for ecommerce?
99.95% is a common target for mid-to-large retailers, though the right number depends on your infrastructure maturity and risk tolerance.
