Business Downtime Calculator
Unexpected downtime is one of the most costly challenges a business can face. Whether it’s caused by equipment failure, cyberattacks, utility outages, or natural disasters, downtime halts productivity and directly impacts your bottom line. The Business Downtime Calculator is a vital tool for estimating the financial impact of these disruptions in real time.
By understanding the cost of every hour lost, businesses can justify investments in risk management, backups, or system upgrades. This calculator helps both small businesses and enterprise-level operations assess risk exposure and make data-informed decisions to minimize potential losses.
Formula
The formula for calculating business downtime cost is:
Downtime Cost = (Revenue Loss per Hour × Downtime Hours) + (Employee Hourly Cost × Downtime Hours)
This formula accounts for both:
- Lost revenue due to halted operations.
- Ongoing employee wages or labor costs even when no work is being performed.
For example, if your average hourly revenue is $1,000 and your employee cost is $300 per hour, and you experience 5 hours of downtime:
Downtime Cost = ($1,000 × 5) + ($300 × 5) = $6,500

Example Calculations
- Example 1:
Downtime: 3 hours
Revenue/hour: $800
Employee Cost/hour: $250
→ Total = ($800 × 3) + ($250 × 3) = $3,150 - Example 2:
Downtime: 1.5 hours
Revenue/hour: $2,000
Employee Cost/hour: $700
→ Total = $4,050 - Example 3:
Downtime: 6 hours
Revenue/hour: $500
Employee Cost/hour: $200
→ Total = $4,200
