Marine Cargo Insurance Calculator

Premium from cargo value, freight, and coverage type.

About this calculator

Marine cargo insurance premiums are priced off the insured value, not the raw cargo value, and this calculator builds that up the way underwriters do: it adds cargo value to freight cost to get the CIF (Cost, Insurance, Freight) value, then applies a markup — 10% by default — to reach the insured value, reflecting the standard practice of insuring cargo for more than its bare cost to also cover anticipated profit that would be lost in a claim. The base premium rate itself depends on which Institute Cargo Clause you select: ICC-A ("all risk," the broadest coverage) is priced here at 0.25% of insured value, ICC-B (named perils only) at 0.15%, and ICC-C (a restricted set of major casualties) at 0.10% — reflecting that broader coverage costs more. An optional war risk premium percentage is added on top for shipments through conflict zones, and the calculator enforces a $100 minimum premium floor, since insurers rarely write a policy for less regardless of how small the calculated rate would be.

It also reports an effective rate (premium as a percentage of the original cargo value, not the marked-up insured value) and a rough deductible estimate at 2% of insured value, a common though not universal figure. The rates and markup used here are illustrative industry-typical figures, not a specific insurer's actual rate card — real premiums vary by underwriter, trade lane, vessel age, and cargo type, so use this output to budget the shipment rather than to bind an actual insurer's quote. For most commercial shipments, the incremental cost of upgrading from ICC-C or ICC-B to all-risk ICC-A coverage is modest relative to the protection gained.

How to Use This Calculator
  1. Enter Cargo Value and Freight Cost — most policies cover CIF + 10% markup.
  2. Select Coverage Type: ICC-A (all risk), ICC-B (named perils), or ICC-C (limited named perils).
  3. Set Value Markup % — standard 10% above CIF protects against profit loss.
  4. Enter War Risk Premium % if shipping through conflict zones.
  5. Review Total Premium and coverage structure.
  6. ICC-A (all risk) is recommended for most commercial shipments — the additional premium is modest relative to coverage.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Cargo Value ($) = 100000, Freight Cost ($) = 5000, Coverage (1-3) = 1, Value Markup (%) = 10 = 5 input(s) provided
  2. Calculate Total Premium
    Total Premium = max(100, totalPremium)
    288.75 = $288.75
  3. Calculate Base Premium
    Base Premium = insuredValue * (baseRate / 100)
    288.75 = $288.75
  4. Calculate War Risk Premium
    War Risk Premium = insuredValue * (warRiskPremiumPct / 100)
    0 = $0

Frequently Asked Questions

Why is my insured value higher than my cargo value?

The calculator first adds Cargo Value to Freight Cost to get the CIF value, then applies the Value Markup % (10% by default) on top of that. This reflects standard marine insurance practice of covering more than the bare cost of goods — the markup exists to also protect the anticipated profit that would otherwise be lost if a claim occurred.

What's the actual difference between ICC-A, ICC-B, and ICC-C coverage?

They're the three Institute Cargo Clauses tiers, and this calculator prices them at different base rates against insured value: ICC-A ('all risk,' the broadest coverage) at 0.25%, ICC-B (named perils only) at 0.15%, and ICC-C (a restricted set of major casualties) at 0.10%. The rate difference reflects that broader protection costs proportionally more, though for most shipments the extra premium for upgrading to ICC-A is modest relative to the coverage gained.

Why did my premium come out to exactly $100 even though the formula suggests less?

The calculator enforces a $100 minimum premium floor — Total Premium is calculated as the greater of $100 or the computed base-plus-war-risk premium. Insurers rarely write a cargo policy for less than that regardless of how small the underlying calculated rate would be, so very low-value or low-rate shipments will show this floor rather than the raw formula result.

When should I add a War Risk Premium?

War Risk Premium (%) is additive on top of the base coverage premium and should only be nonzero if the cargo transits through a designated conflict zone or high-risk area, since standard ICC-A/B/C coverage typically excludes war-related losses. If your route doesn't pass through such a zone, leaving it at 0% is standard.

Is the Estimated Deductible figure a fixed rule?

No — it's a rough planning figure calculated as 2% of the insured value, chosen because that's a commonly seen deductible level in marine cargo policies, not a universal or regulatory one. Actual deductibles are set by the underwriter and can vary by cargo type, trade lane, and claims history.
