$7M+ per day
Derived from the enterprise median of $300,000+ per hour (ITIC 2024) sustained across 24 hours — an outer-bound reference for large enterprises.
Cost per day
A full day down changes the conversation.
Cost per day is the figure disaster recovery and business continuity teams need — the point where an outage stops being an incident and starts being an event with board visibility. Model it with your fleet size, revenue impact, MTTR, incident frequency, and SLA target.

When it becomes a disaster
Multi-day outages don't scale linearly.
A ten-minute blip and a full-day regional outage are not the same problem scaled up. Past a certain point, secondary effects — inventory drift, batch job backlogs, customer support surge, regulatory notification clocks — start compounding on top of the base rate.
Cost per day
Cost per hour multiplied by 24 — the baseline for a sustained, full-day outage across the affected fleet.
Backlog compounding
Batch jobs, queued transactions, and deferred reconciliation add recovery work that scales with outage length, not just severity.
Support surge cost
A full day down typically multiplies inbound support volume, adding staffing cost the base model does not directly capture.
Disclosure and compliance clock
Many regulatory and contractual notification windows are measured in hours or days, turning a long outage into a compliance deadline, not just a technical one.
Benchmarks
What a full day costs at scale.
Multi-day, high-profile outages are rare but expensive enough to shape entire disaster recovery budgets. Use these as an outer bound, not a typical case.
$24K–$120K per day
Typical range for small and mid-size businesses, translated from the $1,000–$5,000 per hour SMB benchmark.
Non-linear recovery
Recovery time after a multi-day outage is rarely proportional to outage length — backlog clearing and data reconciliation often add days beyond the visible incident window.
FAQ
Cost per day, answered.
Questions that come up when a full-day outage becomes a disaster recovery or business continuity conversation.
How do I calculate cost per day of downtime?
Multiply the cost per hour (servers affected times revenue impact per server hour) by 24. Add the hidden outage tax for a fully loaded figure.
Is a full-day outage cost simply 24 times the hourly rate?
As a baseline, yes — but real multi-day outages often add backlog, support surge, and compliance costs that push the true figure above a simple linear multiple.
How does this feed into a disaster recovery budget?
A credible per-day figure gives finance a way to compare the cost of an outage against the cost of redundancy, failover infrastructure, and DR testing — the standard build-versus-accept-the-risk tradeoff.
How does this relate to cost per hour and per minute?
All three are the same underlying rate at different time scales. See the cost per hour and cost per minute calculators, or the full annual model.
