Lost Profits Calculator
Business disruptions, contract breaches, or unexpected events can result in significant revenue loss. When seeking compensation or evaluating financial damage, it’s crucial to understand how much profit was actually lost—not just revenue. That’s where a Lost Profits Calculator comes in. This tool helps you estimate financial damages by accounting for expected revenue, actual revenue, fixed costs, and cost savings. Whether you’re preparing for a lawsuit, an insurance claim, or internal reporting, this calculator provides clarity and supports your financial position with solid numbers.
✅ Formula
The formula to estimate lost profits is:
Lost Profits = (Expected Revenue – Actual Revenue) – Fixed Costs + Variable Costs Saved
Where:
- Expected Revenue: The income you anticipated earning under normal operations.
- Actual Revenue: What you actually earned during the disruption.
- Fixed Costs: Expenses that continued despite the interruption (e.g., rent, salaries).
- Variable Costs Saved: Costs you avoided by not operating at full capacity (e.g., raw materials, hourly labor).
✅ How to Use
- Enter Expected Revenue: This is the revenue you reasonably expected to earn if the disruption had not occurred.
- Input Actual Revenue: Record what you actually earned during the affected period.
- Enter Fixed Costs: These are ongoing expenses you still had to pay even though your revenue dropped.
- Enter Variable Costs Saved: Any expenses you didn’t have to pay due to the disruption should go here.
- Click “Calculate”: The calculator will output an estimated amount of lost profits.
This result helps you assess damages for financial reports, litigation, or insurance reimbursement.
✅ Example
Let’s walk through an example:
- Expected Revenue: $50,000
- Actual Revenue: $30,000
- Fixed Costs: $10,000
- Variable Costs Saved: $2,000
Step-by-step Calculation:
- Revenue Shortfall = $50,000 – $30,000 = $20,000
- Adjusted Lost Profit = $20,000 – $10,000 + $2,000 = $12,000
So, the estimated lost profits are $12,000.
