Downtime Cost Calculator

Reliability is easy to defer until you price it. Enter your revenue and current availability to see what an hour offline costs, your annual exposure, and exactly what each additional "nine" is worth — so the reliability conversation stops being abstract.

That's the price of the status quo. Closing the gap between tiers is usually cheaper than one bad outage — I'll help you find the highest-leverage fixes.

A planning estimate, not your P&L. Revenue/hour is annual ÷ 8,760; downtime hours come straight from the availability gap. Share the link to align engineering and finance on the same number.

Why each "nine" is worth real money

Going from 99.9% to 99.99% cuts allowed downtime from about 8.8 hours a year to 53 minutes. Multiply the hours you remove by what an hour costs and you get the value of the next nine — usually far more than the engineering to earn it.

The model stays honest: revenue lost while down is rarely 100% (some sales just shift later), so dial it to what's realistic for you, and add the team's firefighting cost to capture the hours an incident burns beyond the outage itself.
