Downtime Costs

The Growing Cost of Downtime

According to a report from ITIC, 44% of enterprises face downtime costs exceeding $1 million per hour, with this figure rising due to more frequent and damaging security hacks and breaches. A single minute of server downtime for high-critical systems can range from $4,998 to $16,700. The increasing frequency of these events—attributable to factors like cyberattacks and supply chain disruptions—means downtime costs have grown by 32% over the past seven years.

The Ponemon Institute also revealed that in 2021, the average cost of a data breach was $4.24 million, a 10% increase from 2019. Lost business and customer churn accounted for the largest share of these costs. These figures underscore the severity of downtime in today’s interconnected and fast-moving business environments.

Calculating the Average Cost of Downtime – True Cost in 2024

What is Downtime?

Downtime refers to the period when a system, network, or service is unavailable due to an incident—whether it’s caused by a cyberattack, hardware failure, or human error. Downtime affects an organization’s productivity, customer satisfaction, and revenue.

Why Downtime Costs Matter

Even brief downtime events can have substantial financial consequences. Factors such as the industry you’re in, the criticality of the affected systems, and the duration of the outage all contribute to the total cost.

  • Industry Impact: Highly regulated industries like healthcare and finance suffer the most from downtime. For example, an hour of downtime in financial services can result in $500,000 or more in lost transactions.
  • Business Size: Large enterprises may incur greater downtime costs due to complex infrastructure and high transaction volumes. Small businesses may experience proportionally significant impacts, though on a smaller financial scale.

Factors Driving Downtime Costs

Downtime costs stem from a variety of sources. Here’s a breakdown of the key factors that contribute to the overall financial impact of a disruption:

  • Lost Revenue: When systems go down, sales and transactions halt. For e-commerce and service businesses, this can mean a direct hit to the bottom line.

  • Productivity Loss: Employees are left idle when access to systems and data is unavailable. This can quickly add up, especially in companies with large workforces dependent on network systems to carry out their jobs.

  • Recovery Efforts: The time and resources spent on recovering lost data, repairing systems, and ensuring full restoration often requires overtime, IT specialists, and external consultants—all of which incur costs.

  • Compliance Fines: In industries like healthcare and finance, downtime can lead to non-compliance with regulations such as HIPAA or SOX, resulting in hefty fines and legal consequences.

  • Customer Dissatisfaction: If downtime affects customer-facing systems, customer trust is quickly eroded. For instance, repeated incidents can lead to churn, reputation damage, and negative press.

By understanding these cost drivers, companies can identify where investments in cybersecurity and system reliability will have the greatest return.

Calculating Downtime Costs

To calculate the cost of downtime for your organization, follow these steps:

  1. Identify Key Variables:

    • Revenue Per Hour: Calculate how much revenue your organization generates per hour.
    • Number of Employees Affected: Determine the number of employees impacted by the downtime.
    • Employee Hourly Rate: Calculate the average hourly wage of these employees.
    • Downtime Duration: Estimate the total time the system is expected to be down.
  2. Downtime Cost Formula:

    • Downtime Cost = (Revenue Per Hour × Downtime Duration) + (Number of Employees × Employee Hourly Rate × Downtime Duration)
Risk Formula

How to Calculate Your Business’s Downtime Costs

To make the impact of downtime tangible for your business, here’s a simple formula you can use:

Downtime Cost = (Lost Revenue per Hour + Lost Productivity per Hour + Recovery Costs per Hour) × Hours of Downtime

  • Lost Revenue per Hour: This can be calculated by taking your company’s average annual revenue and dividing it by the total number of business hours in a year.

  • Lost Productivity per Hour: Multiply the number of affected employees by their average hourly wage and add the productivity loss (which could be partial, say 50% of their effectiveness).

  • Recovery Costs per Hour: This includes IT costs, overtime pay, consultants, and the cost of restoring data and systems.

Example Scenario 

Example 1: For a mid-sized company with $50 million in annual revenue, 100 employees affected, and an IT recovery rate of $10,000 per hour, a four-hour downtime could cost:

  • Lost Revenue = $50,000
  • Lost Productivity = $10,000 (100 employees × $50 average hourly wage × 50% effectiveness)
  • Recovery Costs = $40,000

Total Cost for 4 hours of downtime = $100,000

Example 2: Let’s say your company is an e-commerce platform. Here’s how you can estimate the downtime cost:

  • Revenue Per Hour: $100,000
  • Number of Employees Affected: 50
  • Employee Hourly Rate: $30
  • Downtime Duration: 4 hours

Step 1: Calculate revenue loss:

  • $100,000 (Revenue Per Hour) × 4 hours = $400,000

Step 2: Calculate employee productivity loss:

  • 50 employees × $30 per hour × 4 hours = $6,000

Step 3: Add both losses to get the total downtime cost:

  • $400,000 + $6,000 = $406,000

In this case, the estimated cost of 4 hours of downtime for this e-commerce business is $406,000.

Long-Term Impacts of Frequent Downtime on Business Operations

Downtime incidents don’t just have short-term financial consequences; frequent downtime can lead to long-term damage, particularly to your company’s brand, reputation, and competitive edge.

  • Customer Trust: Repeated outages erode customer confidence, and many may opt to switch to competitors who can offer more reliable service. Studies show that 76% of consumers will leave a brand after two or more unsatisfactory experiences.

  • Reputation: Businesses with consistent downtime may be perceived as unreliable, which can affect future partnerships and customer acquisition. Negative press and social media backlash can cause lasting damage.

  • Competitive Positioning: When a company struggles with frequent downtime, it risks losing its market position to competitors that offer more stable services. In industries like fintech or e-commerce, reliability is often a key differentiator.

    • Medium likelihood implies that the event may happen occasionally, but not as frequently as the more common risks. Examples include insider threats or mobile device attacks.
  • Low: 10% – 40%

    • A low likelihood represents events that are less likely to occur but are still possible. Zero-day exploits or some nation-state infrastructure attacks might be placed here.

These percentages reflect the frequency of occurrence in a given period (typically a year), based on historical data and trend analysis.

Calculating Average Cost of Cybersecurity Risk (e.g. Cost of a Data Breach)

True Cost of Downtime – Single Loss Expectancy (SLE): Calculating % Exposure in a Cyberattack

In risk management, Single Loss Expectancy (SLE) helps determine the financial impact of a cybersecurity event. The formula for SLE is:

SLE = Asset Value × Exposure Factor (EF)

The Exposure Factor (EF) represents the percentage of loss a particular asset would suffer in a cyberattack. This percentage is based on how vulnerable an asset is and the anticipated damage from a specific threat.

Determining % Exposure (EF):

  1. Asset Criticality: Evaluate how critical the asset is to your business operations. High-value assets like customer data or financial systems usually have a higher exposure factor, as their compromise can cause major disruption.

  2. Threat Likelihood: Consider the type of threat and its potential impact on the asset. For example, ransomware that encrypts sensitive data may lead to an EF of 80%, while a DDoS attack that only causes a temporary service outage might have an EF of 20%.

  3. Existing Safeguards: Analyze how well the asset is currently protected. If the company has robust encryption and intrusion detection systems in place, the exposure factor will be lower because these measures reduce the potential damage.

  4. Incident History and Scenarios: Review past incidents or simulated attack scenarios to estimate the degree of loss. If prior breaches led to 30% data loss or revenue impact, this can help set the EF for future risk calculations.

Annual Loss Expectancy (ALE) and Value of Safeguard (VoS)

  1. Annual Loss Expectancy (ALE): The Annual Loss Expectancy is a risk assessment formula used to determine the potential annual financial impact of a threat to an organization. It is calculated by multiplying the Single Loss Expectancy (SLE)—the monetary loss expected from a single incident—by the Annual Rate of Occurrence (ARO), which is the estimated number of incidents expected to occur in a year.

    Formula:

    • ALE = SLE × ARO
  2. Value of Safeguard (VoS): The Value of Safeguard is a way to measure the effectiveness and financial benefit of a security control or safeguard by evaluating how much it reduces your ALE. It is calculated by comparing the ALE before and after implementing a safeguard, then subtracting the annual cost of maintaining the safeguard.

    Formula:

    • VoS = ALE(before) − ALE(after) − Annual Cost of Safeguard

By calculating both ALE and VoS, organizations can determine whether the cost of implementing security measures is justified by the reduction in risk and potential losses.

To effectively assess the financial risks, companies should calculate their Single Loss Expectancy (SLE), Annual Loss Expectancy (ALE), and Value of Safeguard (VoS). These are foundational metrics in risk management that help quantify the potential impact of security incidents:

  • Single Loss Expectancy (SLE): This represents the potential loss from a single event. It is calculated using the formula:
    SLE = Asset Value x Exposure Factor (EF)
    Example: If a critical server valued at $500,000 has a 20% exposure during a cyberattack, the SLE is $100,000.

  • Annualized Loss Expectancy (ALE): This extends the SLE to estimate potential yearly losses, accounting for the frequency of incidents.
    ALE = SLE x Annual Rate of Occurrence (ARO)
    Example: With an ARO of 0.5, the ALE would be $50,000 annually.

  • Value of Safeguard (VoS): VoS measures the cost savings from implementing security measures.
    VoS = ALE (before safeguard) − ALE (after safeguard) − Annual Cost of Safeguard
    Example: If an Intrusion Detection System (IDS) reduces ALE from $100,000 to $50,000, and the IDS costs $20,000 annually, the VoS is $30,000—a clear return on investment (ROI) from cybersecurity measures.

Summary of the Cybersecurity Scenario

Consider a company with an annual loss expectancy (ALE) of $100,000 due to network breaches. They install an IDS that reduces the ALE to $50,000, with an annual cost of $20,000. Using the formula:

  • VoS = ($100,000 – $50,000) – $20,000
  • VoS = $30,000

In this case, the safeguard delivers $30,000 in savings annually by reducing potential loss.

Preventing Cybersecurity-Related Downtime

Cyberattacks are one of the leading causes of costly downtime. From ransomware attacks that encrypt vital data to DDoS attacks that crash critical systems, businesses need to implement targeted defenses to minimize the risk.

Key strategies include:

  • Zero Trust Architecture: Adopt a Zero Trust approach where access is continuously verified at every stage. This limits exposure to internal threats and unauthorized access.

  • Endpoint Protection: Ensure all devices, including employee laptops and mobile devices, have up-to-date security software to prevent breaches from spreading through the network.

  • Regular Patching: Many cyberattacks exploit known vulnerabilities. Keeping systems patched and updated is essential to close these gaps.

Case Study: In 2023, a large financial services company experienced a ransomware attack that resulted in a 3-day downtime. By having a Zero Trust network and a robust recovery plan, they were able to recover systems within 24 hours without paying the ransom—saving them millions in potential downtime costs.

Justifying Downtime Prevention Investments to Leadership

One of the biggest challenges IT teams face is convincing leadership to allocate budget for downtime prevention. Here’s how to frame the discussion:

  • Use Data: Present downtime cost estimates for your business, including lost revenue, recovery efforts, and potential compliance penalties. Showing the numbers can make the abstract concept of downtime more concrete.

  • ROI of Prevention: Compare the cost of investing in preventive technologies like cybersecurity tools or redundant infrastructure to the costs of a potential downtime incident. Investments in downtime prevention often pay for themselves many times over by preventing catastrophic losses.

  • Risk Mitigation: Highlight the non-financial benefits as well, including risk mitigation and regulatory compliance. Downtime in highly regulated industries can result in legal penalties far exceeding direct financial losses.

How to Recover from Cyberattack-Induced Downtime

No matter how robust your defenses, cyberattacks are sometimes unavoidable. Having a solid recovery plan can minimize downtime and reduce costs.

  • Containment: Immediately isolate affected systems to prevent the attack from spreading. This may include shutting down specific services or network segments.

  • Restoration: Work with your IT team to restore systems from the most recent clean backups. If your data is encrypted by ransomware, having offline backups is key to a quick recovery.

  • Communication: Inform your stakeholders—customers, employees, partners—about the incident and provide a clear timeline for resolution. Transparency helps maintain trust during recovery.

  • Post-Incident Review: After recovering from downtime, conduct a thorough review to identify what went wrong and implement improvements to prevent future incidents.
