About this calculator
FOB and CIF are the two most common ways to quote a sea export or import price. FOB (Free On Board) is the price of the goods on board the vessel at the port of loading; freight and insurance are for the buyer. CFR (Cost and Freight) adds sea freight to the port of destination. CIF (Cost, Insurance and Freight) further adds the cargo insurance the seller must buy. Buyers often ask for CIF quotes so they can compare offers, while sellers work out their cost on an FOB basis, so converting back and forth is an everyday task.
A common mistake is to calculate the insurance premium on FOB or CFR alone. Under Incoterms 2020, CIF insurance must cover at least 110% of the contract price, with at least Institute Cargo Clauses (C) cover. Because the premium is charged on the CIF value, which already contains the premium, the correct formula is CIF = CFR ÷ (1 − rate × 110%). The difference is small per shipment, but it can make the invoice, the policy and the L/C documents disagree.
This calculator works both ways. FOB → CIF adds the freight and then the insurance; CIF → FOB takes the premium and the freight off a CIF price requested by the buyer. Insurance can be a percentage (with an editable uplift) or a fixed amount from your insurer's quote. For containers, Incoterms recommends the equivalents FCA, CPT and CIP; the arithmetic is the same, only the delivery point and insurance cover differ.
Worked example
An export quote of FOB USD 20,000, sea freight USD 1,500, insurance rate 0.3% with an insured value of 110% of CIF:
- CFR = 20,000 + 1,500 = USD 21,500
- CIF = 21,500 ÷ (1 − 0.003 × 1.1) = 21,500 ÷ 0.9967 = USD 21,571.18
- Premium = USD 71.18; insured value = 21,571.18 × 110% = USD 23,728.30
Worked backwards, CIF USD 21,571.18 returns exactly to FOB USD 20,000. With a fixed insurance amount of USD 5, FOB 1,000 + freight 100 becomes CIF USD 1,105.
How to use it
Choose the direction
Pick FOB → CIF to build a CIF quote, or CIF → FOB to find the FOB value behind a CIF price you were asked for.
Enter price and freight
Enter the FOB or CIF price, the currency and the sea freight to the port of destination.
Set the insurance
Enter the premium rate and uplift (10% by default, so the insured value is 110% of CIF), or choose a fixed amount.
