One of the most misunderstood clauses in Business Interruption (BI) insurance is the Gross Profit vs Revenue Basis. Many businesses select a basis during policy placement without fully appreciating how it determines the actual claim payout after a loss.
This clause does not merely influence premiums. It defines what financial loss the insurer will replace when insured damage interrupts business operations. Choosing the wrong basis rarely shows up at inception, but it becomes painfully visible at claim stage.
What Does the Gross Profit vs Revenue Basis Clause Do?
The clause answers one critical question in a BI claim:
What financial measure will the insurer indemnify while the business is interrupted?
The answer determines whether the policy replaces lost earnings, lost cashflow, or something in between. Selecting an unsuitable basis does not reduce cost alone — it distorts the claim outcome.
A. Gross Profit Basis
What It Is
Under the Gross Profit Basis, the insurer compensates for:
- Loss of Turnover
- Less uninsured variable costs
In practical terms, this basis protects the profit-generating capacity of the business, not total sales. Costs that naturally reduce when operations stop are not insured, because they do not represent a real financial loss.
This basis is most suitable where:
- Revenue fluctuates with production or trading volume
- Variable costs reduce when operations cease
How It Is Applied
A claim under the Gross Profit Basis measures:
- Standard Turnover (what the business would have earned)
- Actual Turnover after the loss
- The difference, adjusted for savings in variable costs
Only the net impact on gross profit is payable.
Practical Example: Manufacturing Factory
- Monthly turnover before fire: $1,000,000
- Variable costs (raw materials, power): $600,000
- Gross profit: $400,000
A fire shuts down operations. Under a Gross Profit Basis BI policy, the insurer pays $400,000 per month (subject to policy limits and indemnity period).
Savings on raw materials are not insured — which is correct, because those costs were never incurred.
Why Gross Profit Basis Is Used
- Reflects the true financial loss
- Prevents over-insurance
- Aligns with manufacturing and trading business models
B. Revenue (Turnover) Basis
What It Is
Under the Revenue Basis, the insurer compensates for:
- Loss of Turnover only
Costs are not deducted. This basis is appropriate where expenses remain largely fixed, even when revenue stops.
It is most suitable where:
- Operating expenses continue during closure
- Cashflow continuity is critical for survival
How It Is Applied
The claim compares expected turnover against actual turnover during the interruption. The difference is payable, subject to policy limits.
Practical Example: Hotel or Professional Services Firm
A hotel closes due to fire damage. Despite no guests:
- Staff salaries continue
- Loan repayments continue
- Utilities, security, insurance continue
Revenue Basis ensures ongoing cash inflow to meet fixed obligations and keep the business viable.
Why Choosing the Wrong Basis Is Risky
Scenario 1: Factory Insured on Revenue Basis
- Insurer pays full turnover
- Variable costs were saved
- Claim becomes inflated, disputes likely
Scenario 2: Hotel Insured on Gross Profit Basis
- Insurer deducts costs that never stopped
- Claim underpays actual cashflow needs
- Business struggles despite a valid claim
Common BI Claim Disputes Linked to This Clause
- Incorrect classification of variable versus fixed costs
- Misunderstanding the business operating model
- Under-insurance due to wrong basis selection
- Disagreements on cost savings
Key Takeaways
- Gross Profit Basis protects earnings capacity.
- Revenue Basis protects cashflow continuity.
- There is no universally better basis — only a correct one.
- Wrong basis selection fails at claim stage, not placement.
