Single points of failure
Without redundant infrastructure, one outage can take down the entire operation rather than a fraction of it.
Small business
Smaller numbers, bigger relative hit.
A small business outage rarely produces a headline-grabbing dollar figure — but it can consume a much larger share of monthly revenue than the same relative outage would at an enterprise. Defaults below reflect a small operation without dedicated SRE staff.

Proportional risk
No SRE team means no error budget cushion.
Enterprises absorb outages with redundant infrastructure and dedicated on-call staff. A small business often runs on a single point of failure — a POS system, a website host, a shared server — which means the same outage frequency carries more real risk.
Owner-operator time cost
In many small businesses, the owner personally handles incident response, which is a direct cost against the business's most constrained resource.
Cash flow sensitivity
A single bad outage day can materially affect monthly cash flow in a way that would barely register for a larger organization with more revenue diversification.
FAQ
Small business outage cost, answered.
Questions that come up when sizing the cost of downtime for a small operation.
Is a 99% SLA target realistic for a small business?
It's a reasonable starting point without dedicated infrastructure investment — closer to 3.65 days of allowed downtime per year. See the SLA calculator to compare against higher targets.
What should I use for the revenue impact input?
Average hourly revenue during operating hours is a simple starting point — divide typical daily revenue by hours open.
Should owner time be counted as a cost?
Yes — value the owner's time at a reasonable hourly rate and include it as part of the hidden cost, since it's time not spent on growth or other work.
Is investing in redundancy worth it at small scale?
Compare the annual cost this calculator estimates against the cost of basic redundancy (backup connectivity, a secondary payment processor) — often a modest investment pays for itself after one avoided incident.
