There is no universal hourly price for a small-business website outage. A lead form that stops working, an online shop that cannot accept payment, and a brochure site with no transaction path create very different losses. Your defensible figure comes from your own traffic, conversion rate, contribution margin, outage timing, advertising, and recovery workload. Published surveys can provide context, but they are not a quote for your business.
What does website downtime cost a small business?
The cost is the total economic effect of a specific incident, not simply annual revenue divided by the number of hours in a year. Start with what the site normally produces during the affected period, then add the work and remediation required because it failed. A quiet overnight outage may cost little; a checkout failure during a paid campaign or a booking outage before a fully booked weekend can be expensive.

Business type changes the exposure:
- Online stores: missed orders and abandoned carts are usually the most visible loss.
- Lead-generation sites: the cost is the expected value of qualified enquiries that never arrive, not the value of every page view.
- Booking and appointment sites: lost reservations, staff rescheduling, and refunds can outweigh the original sale.
- Brochure sites: the immediate financial loss may be small, although a high-value prospect or a paid campaign can still be affected.
Infrascale’s May 2020 survey of more than 500 SMB C-level executives illustrates why no single rate works. Thirty-eight percent said they did not know their cost for one hour of downtime, 37% said they had lost customers, and 17% said they had lost revenue. Among respondents who supplied an hourly estimate, 10% reported more than $50,000, 25% reported $20,001–$40,000, 26% reported $10,000–$20,000, and 27% reported under $10,000. These are respondent estimates from a broad business-downtime survey, not a current website-only benchmark. Read the survey scope and findings.

The same announcement reported software failure (53%) and cybersecurity issues (52%) among common causes of downtime that created business challenges for its respondents. Those percentages describe that survey group; they do not predict the cause of your next outage. Infrascale CEO Russell P. Reeder said, “Customer retention is essential for business success,” in the announcement, a reminder that customer effects may extend beyond the period when the site is unavailable.

How to calculate the cost of an hour of downtime
Build a scenario for a defined date and time—for example, Tuesday from 10:00 to 11:00—and use normal performance for that same period whenever possible. Keep assumptions visible so you can replace them with measured figures later.
1. Estimate interrupted sales or leads
For a shop, estimate the orders that would normally complete during the outage and multiply them by contribution margin, not gross sales. Contribution margin is the portion left after variable costs such as goods, payment fees, shipping, and sales commissions. For a lead site, multiply expected qualified leads by a defensible expected value per lead. Use the conversion and close rates your business actually observes.
2. Add paid traffic that went nowhere
Record campaign spend incurred while visitors were sent to an unavailable or unusable page. Include search, social, display, and sponsored links only for the outage window. Do not count the same lost sale twice: if an order is already represented in missed contribution margin, do not add its full revenue again as a separate loss.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute3. Price staff time at loaded cost
Count time spent diagnosing the problem, opening support tickets, contacting a developer or host, answering customer messages, rescheduling appointments, and reconciling forms or orders after recovery. Multiply hours by loaded labor cost, including payroll taxes and benefits where those costs apply.
4. Record direct customer remediation
Include refunds, rebooking discounts, manual order handling, payment or form reconciliation, and paid restore work. Separate one-time incident work from routine payroll so the estimate shows what the outage added.
5. Describe longer-term effects without false precision
Customer churn, negative reviews, missed repeat purchases, and damaged trust can matter, but a precise dollar value requires your retention and lifetime-value data. State these effects separately or model them with an explicit assumption. Do not assign a made-up reputation amount.
6. Add contractual, regulatory, or security costs only when applicable
Consider notification, forensic, or contractual obligations only if the affected data, service agreement, and jurisdiction make them relevant. No general legal penalty applies to every small-business website outage.

Use this compact equation:
Estimated incident cost = missed contribution margin + wasted campaign spend + staff and recovery labor + direct customer remediation + clearly stated other scenario costs.
A worked example using your own assumptions
Suppose an online shop normally receives 12 orders per hour during a weekday campaign. Its average order is $45, and its contribution margin after variable costs is 60%. A one-hour outage therefore threatens an illustrative $324 in contribution margin (12 × $45 × 0.60). If $80 in advertising still sends clicks to the failed page, two employees spend 1.5 hours each on diagnosis and customer messages at a loaded $30 per hour ($90), and refunds or rebooking concessions total $50, the direct estimate is $544.
The $544 is not a benchmark; it is the result of the stated assumptions. Replace every input with your analytics and accounting data. If the outage lasts three hours, do not automatically multiply by three: traffic, conversion, campaign timing, and staff workload may change by hour. A lunchtime outage can be more costly than an overnight outage even at the same duration.
Why published downtime figures can mislead you
Large-company statistics often describe systems whose failure stops thousands of employees or high-volume transactions. New Relic’s 2024 Observability Forecast reported median hourly costs of $1.3 million for high-business-impact outages at “small organizations,” $2.0 million at midsize organizations, and $2.1 million at large organizations. In that broad observability survey, “small” does not mean a representative small-business website, so those medians should not be used in your worksheet. The report also found 118 annual downtime hours among respondents using observability versus 445 hours with more manual detection; that is an association in survey responses, not proof that a particular monitoring product will prevent a loss. See New Relic’s definitions and methodology.
An unnamed senior director of IT infrastructure at a large U.S. fintech told New Relic, “On average, I can say that a minute of downtime can cost $10,000 or more. Every single minute of downtime can be lost revenue for the company. If you’re down for one hour, it can cost millions.” That is an enterprise respondent’s statement, not a typical small-business claim.
ITIC’s 2024 discussion gives arithmetic illustrations rather than measured averages: an assumed $10,000 hourly loss equals approximately $167 per minute, while an assumed $25,000 hourly loss equals approximately $417 per minute. ITIC also notes that micro-SMBs usually do not incur enterprise-scale hundreds of thousands or millions in hourly losses, even though smaller firms may have fewer reserves to absorb disruption.

PagerDuty’s June 2024 survey covered 500 IT leaders at companies with more than 1,000 employees in the United States, United Kingdom, and Australia. It estimated $4,537 per minute and $794,000 per incident based on a 175-minute average incident—figures for an enterprise population, not a small-business website. PagerDuty CIO Eric Johnson attributed incidents to “increased complexity, rapid expansion of digital services and insufficient investment in IT infrastructure maintenance”; that is the vendor executive’s characterization of its survey findings.

What does website downtime cost besides lost sales?
Interrupted customer work
A failed form can erase a qualified enquiry; a broken booking flow can create empty appointment slots; and a payment error can leave an order in an uncertain state. Keep a log of calls, emails, abandoned carts, and duplicate submissions so you can quantify the manual follow-up.

Campaigns continue to buy visits even when the landing page fails. Pause campaigns as soon as the incident is confirmed, and preserve the platform report for the outage interval so the spend is auditable.
Recovery and reconciliation
After the site returns, staff may need to identify partial payments, resend confirmations, deduplicate leads, restore files, and verify that inventory or calendars are accurate. These tasks can continue long after the homepage loads.
Customer and reputation effects
Repeated failures can cause customers to choose another supplier or question whether their payment or personal information was handled safely. Track complaints, cancellations, review changes, and repeat-purchase behavior rather than assigning an unsupported universal dollar amount.

Evaluate hosting as an operational service
Compare support availability and response expectations, stated service commitments and exclusions, security controls, backup and restore arrangements, traffic capacity, and migration effort. A July 2025 IT Pro report on a commissioned survey of 500 business owners, developers, and IT decision-makers said respondents averaged five hours of downtime per month; one in five reported more than $2,500 in monthly losses from hosting downtime, and businesses averaged $418 per month fixing hosting issues. The population covered multiple company sizes and industries, and the article is a secondary account, so treat these as directional context rather than a small-business website benchmark. It also reported that 26% might switch hosts because of frequent downtime, while nearly seven in ten delayed switching because of downtime, migration cost, or technical complexity. Read the IT Pro report and its limitations.
Liquid Web CTO Ryan MacDonald told IT Pro, “In 2025, businesses should stop viewing hosting as a commodity and start treating it as a critical investment in security, performance, and growth.” That is vendor commentary, not an independent reliability measurement.
Make backups recoverable, not merely present
Check backup scope and frequency, independent storage, retention, restoration testing, expected recovery time, and who is responsible for rebuilding the application. A backup can restore files or data after corruption; it does not keep the site online during an infrastructure failure. Schedule test restores and document the exact steps while the site is healthy.
Assign an incident owner
Decide who receives alerts, who can contact the host or developer, who pauses advertising, who communicates with customers, and who reconciles orders or leads. Keep emergency contacts, DNS access, registrar details, backup locations, and recent change records in a secure, accessible location.

Use the cost worksheet to compare the annual price of each improvement with the loss it could prevent, while recognizing that prevention is not guaranteed.
| Option | Best fit | Questions to ask |
|---|---|---|
| Uptime and transaction monitoring | You need faster detection or the homepage check misses critical workflows. | Does it test forms or checkout, alert multiple people, show check locations, and document incidents? |
| Hosting upgrade or migration | Recurring infrastructure failures, slow support, or capacity limits are the dominant problem. | What support response is stated, which exclusions apply, how are backups restored, and what migration downtime is expected? |
| Independent backup and recovery | You could rebuild after deletion, ransomware, or a failed update only with difficulty. | How often is it copied, where is it stored, when was a restore tested, and who performs recovery? |
| Operational runbook | Alerts arrive but staff lose time deciding what to do. | Are escalation, customer messaging, campaign pausing, and reconciliation steps assigned by name? |
Prioritize the bottleneck your incident history shows. Better hosting cannot compensate for discovering a broken checkout hours later, and monitoring cannot repair a corrupted database without a tested recovery path.
What to do during and after an outage
- Confirm the scope: test the homepage and the key customer action from more than one network; record the start time, symptoms, and affected regions.
- Protect demand: pause paid campaigns and publish a temporary contact or ordering instruction on an alternate channel if available.
- Escalate: contact the host, developer, or security responder with timestamps, recent changes, error messages, and monitoring evidence.
- Preserve records: export campaign spend, form notifications, payment status, booking data, and support tickets before systems are changed.
- Validate recovery: test login, forms, checkout, confirmation emails, integrations, and mobile behavior—not just the homepage.
- Reconcile and learn: contact affected customers, correct duplicate or missing orders, calculate the incident with actual figures, and update monitoring, backups, or procedures based on the root cause.
Recalculate your estimate after every material incident. Over time, a record of outage timing, duration, missed contribution margin, labor, and remediation will give you a more credible investment case than any generic “cost per minute” statistic.
