The Lost Week Calculator: What does one hour of chaos actually cost?

The Concept: Most business owners think a one-hour system outage only costs them two hours of time. In reality, that first hour of chaos creates a "ripple effect" that can steal an entire week’s worth of profit through rework, staff overtime, and lost customer trust.

Use This Calculator To Help Understand L”Lost Week” Costs

Use this simple 3-step math exercise to find your "Lost Week" number:

Step 1: The Direct Revenue Gap

• How to calculate: Take your average total revenue for a single day and divide it by the number of hours you are open. Multiply that number by the hours your system was down.

• The Reality: This is the money that simply didn't happen because you couldn't process a payment or book a client.

Step 2: The Rework Penalty (Staff Time)

• How to calculate: Take the hourly rate of the employees who had to stay late or work through lunch to "catch up" on the data entry, billing, and rescheduling caused by the outage.

• The Reality: You are paying twice for the same work; once when they stood around waiting for the fix, and a second time when you paid them to fix the backlog.

Step 3: The Trust Tax (The Long-Term Loss)

• How to calculate: Estimate the "Lifetime Value" of one loyal customer. If the chaos of the disruption caused just two customers to decide to try your competitor next time, add those values together.

• The Reality: This is the most expensive part of the disruption. One hour of poor communication can erase years of built-up loyalty.

Your Total: Add Step 1, 2, and 3 together. That is your Lost Week Number.

The Solution: You don’t have to accept this as "the cost of doing business." By implementing a First-Hour Stabilization Card, you can cut this number by 80% or more.
