What this calculator does

It measures the financial cost of lost stock after a power cut, equipment failure or handling mistake. It does not decide whether any food is safe. That depends on real food temperature, packaging, handling and official guidance.

The inputs

• Cartons in stock and cartons lost: the stock you held and the part you lost.
• Purchase cost and selling price per carton: what the stock cost and what it would have sold for.
• Disposal costs and recovery value: money spent to dispose of stock, and anything you recover.

The formulas

• Cost of lost stock = cartons lost × purchase cost
• Lost sales value = cartons lost × selling price; lost profit = cartons lost × (selling price − purchase cost)
• Total financial loss = cost of lost stock + disposal costs − recovery value
• Remaining stock value = (cartons in stock − cartons lost) × cost or selling price

Worked example (illustrative)

Twenty cartons bought at 40,000, two lost, selling price 48,000, 2,000 spent on disposal and nothing recovered. Cost of lost stock is 80,000, so total loss is 82,000, which is 10% of stock. The 18 remaining cartons are worth 720,000 at cost and 864,000 at selling price.

Food safety

Check food temperature and follow guidance from your food regulator, such as NAFDAC in Nigeria, or the USDA and FDA elsewhere. The usual rule is to discard food you cannot confirm was kept cold enough. Do not rely on elapsed time alone.

Limits

The result ignores insurance, customer goodwill and any fines. It is an estimate based on your inputs.

FAQ

Does this tell me if my food is safe?

No. It only calculates money. Safety depends on temperature, handling and official guidance.

How can I reduce losses?

Track freezer temperature, keep stock organised, plan backup power and record every loss so you can see patterns.
