Is the annual result a forecast?

No. It reconstructs the entered year; future scenarios depend on the event counts and losses you assume.

What belongs in separate annual charges?

Only actual recovery or penalty charges omitted from the average event loss. Reconcile invoices to prevent overlap.

Can a year have no events but still incur charges?

Yes, such as a settled charge for earlier work recognized this year. The per-event average is then undefined.

Should an uncertain penalty be treated as an actual charge?

No. Enter confirmed charges here; uncertain exposure needs an explicitly separate risk model.

Maintenance & Reliability calculator

Annual Downtime Cost Calculator

Summarize downtime cost for one complete reporting year. Enter recorded events, their average financial loss and actual annual charges excluded from that average.

What this calculator does

Reconcile annual downtime loss from recorded events and separately identified recovery and penalty charges.

Formula used

Event-driven annual loss = annual downtime events × average event loss
Separate annual charges = annual recovery charges + annual penalties
Annual downtime cost = event-driven annual loss + separate annual charges
Average total cost per event = annual downtime cost ÷ annual events

Inputs explained

Annual Downtime Events: Distinct unplanned events recorded in the selected complete year.
Average Event Loss: Average recorded event loss excluding the separate annual charges.
Separate Annual Recovery Charges: Actual annual recovery charges omitted from the event loss average.
Separate Annual Penalties: Confirmed annual penalty charges omitted from other entries.

How to use the result

Best suited to annual outage cost review, recurring event sensitivity.
Losses that vary with outage length require event-level costing. No failure-frequency or penalty probability is estimated.

Current U.S. benchmarks

U.S. manufacturing runs at 75.9% of capacity (Federal Reserve, Sep 2026). New factory orders are up 8.5% year over year (Census).
