How Cargo Insurance Premium Is Calculated
Your premium is a small percentage of your insured value — typically between 0.1% and 0.5%. The insured value is not just the cargo value; it includes freight and a standard 10% uplift for profit and additional costs.
Insured Value = (Cargo Value + Freight) × 1.10
Premium = Insured Value × Rate (%)
Example: Cargo value $10,000, freight $800. CIF = $10,800. Insured value with 10% uplift = $11,880. At a standard sea rate of 0.15%: premium = $11,880 × 0.0015 = $17.82. For electronics at 0.35%: premium = $11,880 × 0.0035 = $41.58.
The 10% uplift is not arbitrary — it's an industry-standard buffer to cover the profit margin and additional expenses (re-ordering, expediting, lost contracts) that arise when a shipment is lost or damaged. Institute Cargo Clauses (ICC) A policies allow this uplift by default.
Typical Rates by Cargo Type and Mode
Rates are set based on cargo type, packaging, transport mode, and the trade lane. These are representative ranges — your actual rate may be higher or lower depending on your insurer, declared commodity, and claims history.
| Cargo Type | Typical Rate Range |
|---|---|
| General cargo (sea freight) | 0.10% – 0.30% |
| Electronics / high-value goods | 0.30% – 0.50% |
| Air cargo | 0.15% – 0.35% |
| Hazardous goods | 0.50% – 1.00%+ |
| Refrigerated / perishable | 0.30% – 0.60% |
| Machinery / project cargo | 0.20% – 0.50% |
Why You Should Not Skip Cargo Insurance
Many importers skip insurance on "low value" shipments — until a container gets damaged, goes overboard, or is delayed in a warehouse fire. The carrier's liability is legally capped at a fraction of the cargo value:
- Sea freight (Hague-Visby Rules): ~$500 per package or $2 per kg — whichever is higher. For a $20,000 shipment in one container, you may recover $500.
- Air freight (Montreal Convention): ~22 SDR per kg (~$30/kg). Better than sea, but still often below actual cargo value for high-value goods.
- Road freight: Varies by jurisdiction and CMR convention. Often similarly limited.
A cargo insurance premium of 0.15% on a $10,000 shipment is $15–$18. If your shipment is lost, that $18 recovers $11,000+. It is one of the most cost-effective risk transfers in international trade.
ICC A vs ICC B vs ICC C — Which Policy Type?
The Institute Cargo Clauses (ICC) are the global standard for marine cargo insurance:
- ICC A (All Risks) — broadest cover. All physical loss or damage except named exclusions (inherent vice, improper packing, war, etc.). Recommended for most commercial shipments.
- ICC B — named perils only: fire, explosion, stranding, collision, earthquake, lightning, sea water entry, jettison. More limited than ICC A.
- ICC C — most restrictive named perils: fire, explosion, stranding, collision, jettison. Not recommended for most cargo.
Always request ICC A. The rate difference between ICC A and ICC C is typically small — the additional premium for full cover is rarely significant relative to the protection it provides.
How to Use This Calculator

- Enter the freight cost for your shipment. If you don't have an exact number yet, use the air freight calculator or your forwarder's estimate.
- Select the rate preset that matches your cargo type and mode, or enter a custom rate if your insurer has given you a specific rate.
- The calculator applies the standard 10% uplift and shows your insured value and estimated premium.
- Use this number as an input in your landed cost calculation.
Frequently Asked Questions
How is cargo insurance premium calculated?
Premium = Insured Value × Rate (%). Insured Value = (Cargo Value + Freight) × 1.10. The 10% uplift is the industry standard to cover anticipated profit and additional expenses. Minimum premiums of $25–$50 are commonly applied by insurers regardless of how small the calculated premium is.
What is CIF value and why does insurance use it?
CIF (Cost + Insurance + Freight) represents the total value of goods at the destination port including transportation costs. Insurance is based on CIF because your financial exposure if cargo is lost includes both the goods and the freight you already paid. Insuring at CIF + 10% ensures you are fully indemnified.
Is cargo insurance mandatory?
Not legally, for most trade lanes. But ocean carriers' liability is capped at ~$500 per package under Hague-Visby rules — far below actual cargo value for most commercial shipments. Under CIF and CIP Incoterms, the seller is contractually required to arrange insurance. For all other Incoterms, the buyer should arrange their own cover.
What does cargo insurance cover?
ICC A (All Risks) covers all physical loss or damage except named exclusions: inherent vice, improper packing, war (unless added by endorsement), and delay. ICC B and C cover named perils only and are more restrictive. Always opt for ICC A with All Risks cover for commercial cargo. Read the exclusions before you bind cover.
What is the difference between marine insurance and cargo insurance?
Marine insurance is the broad category covering all maritime risks — hull (the ship), liability (P&I clubs), and cargo. Cargo insurance is the specific component covering the goods in transit. In trade practice, "marine insurance" and "cargo insurance" are often used interchangeably to refer to the insurance covering shipped goods.
Use Insurance as an Input to Landed Cost
Once you have your premium estimate, plug it into the landed cost calculator as your insurance input. The landed cost tool calculates duty on the full CIF value, so your insurance figure directly affects your duty base. For a complete picture of your import cost, also check the CBM calculator and compare freight options with the LCL vs FCL calculator.
