About this calculator
Marine cargo insurance protects the value of goods against damage or loss in transit. Many new shippers treat it as optional, yet a carrier's liability is very limited: under the international conventions it is capped per package or per kilogram, often far below the value of the goods. For CIF and CIP sales, Incoterms 2020 even requires the seller to buy insurance.
Market practice sets the sum insured at the CIF value plus 10%, i.e. 110% of CIF. The extra 10% stands for lost profit and unexpected costs if the goods are damaged. Premium = sum insured × rate, and the rate depends on the goods, packing, route, mode and cover: Institute Cargo Clauses (A) (all risks, with exclusions) costs more than (B) or (C), which cover named perils only. Almost every insurer also sets a minimum premium per policy, plus policy fees and stamp duty.
This calculator can start from a CIF, CFR or FOB + freight value. If you only know CFR, CIF is found with CIF = CFR ÷ (1 − rate × 110%), because the premium itself is part of the CIF value. The result shows the sum insured, the premium before and after the minimum, the total cost and its share of the goods value, so you can compare insurance quotes quickly.
Worked example
A shipment worth CIF USD 50,000, premium rate 0.25%, uplift 10%, minimum premium USD 25:
- Sum insured: 50,000 × 110% = USD 55,000
- Premium: 55,000 × 0.25% = USD 137.50 (above the minimum)
With a USD 150 minimum premium and a USD 10 policy fee, the total becomes USD 160. From a CFR price of USD 48,000 at the same rate: CIF = 48,000 ÷ (1 − 0.0025 × 1.1) = USD 48,132.36, premium USD 132.36.
