Cost of One Day of Downtime

The cost of one day of downtime translates continuity into the language executives already speak: money. It exists because a recovery investment cannot be judged without knowing what a stopped process actually loses per day. With the number on the table, the board compares the price of protection against the price of standing still. Without it, continuity budgets lose every argument to revenue-generating projects.

The figure is calculated per critical process: lost revenue, contractual penalties and SLA credits, overtime and recovery costs, plus an estimate of customer churn. Finance validates the model, executive management signs it off, and it is kept in the BIA next to the recovery targets. A distributor may find that a stopped order-processing line costs AED 400,000 per day, which makes a warm standby at AED 900,000 per year pay for itself if it prevents three days of outage. The same number justifies the RTO: cutting recovery from 48 hours to 4 has a calculable value.

The usual mistake is counting only lost revenue and ignoring penalties, credits and churn, which understates the loss several-fold. Another is quoting one company-wide average instead of per-process figures, which makes prioritisation impossible. Turning downtime into defensible money is the core of ERGP module M3, Impact analysis and the economics of recovery.
