Downtime Cost Calculator

One hour offline costs more than you think — calculate lost revenue per hour, per outage and per year.

—Revenue lost per hour
—Lost for this outage
—Exposure per year (24/7 rate)

Uptime 99.9% still allows ~8.7 hours of downtime per year.

How it works

Lost revenue per hour = (monthly visitors ÷ 30 ÷ 24) × conversion rate × average order. Multiply by the outage length for the incident cost, and by a year of hours for your total exposure — the real number to weigh against premium hosting and monitoring costs.
