Estimate what an outage costs you, from lost revenue and lost working time.
Two costs are straightforward to estimate and hard to argue with: revenue you did not take while you were down, and salary you paid to people who could not work. Enter your figures and both are calculated below.
What this deliberately does not model: churn, support load after the fact, and reputational cost. Those are real and usually larger, but any number you put on them is invented. Use this figure as a floor, not an estimate, and it will survive contact with a finance team.
