Hire JaykmFrequently asked questions
Are these sourcing calculators really free?
Yes. All three calculators are free to use with no sign-up. They run entirely in your browser.
What is landed cost and why does it matter?
Landed cost is the true total cost of getting goods to your warehouse: product price plus freight, import duty, and port/broker fees. Importers who only look at the unit price often underprice their products.
How accurate are the estimates?
They are planning estimates based on the numbers you enter. Real freight rates, duty rates, and fees change often, so always confirm with your forwarder and customs broker before placing an order.

I'm Jaykm, an independent sourcing agent based in China. I help importers verify suppliers, control quality, and understand their true costs.
Do my numbers leave my browser?
No. Every calculation happens locally in your browser. Nothing you type is sent to any server.
