Why these tools exist
Most importers and wholesalers don't lose money on a single bad decision. They lose it slowly — by quoting from supplier price instead of landed cost, by confusing markup with margin, by buying an MOQ that doesn't fit shelf life, or by ordering a pallet count that wastes container space.
These calculators put the math in plain sight, so the trade-offs are obvious before the purchase order goes out.
Common trade mistakes these tools help prevent
- • Comparing supplier price instead of delivered landed cost.
- • Treating a 30% markup as a 30% margin (it isn't).
- • Accepting an MOQ without checking sell-through against shelf life.
- • Ordering quantities that ship as half-empty containers.
- • Forgetting customs clearance, port handling, and local delivery.
- • Ignoring VAT cash-flow timing on import.

Frequently asked questions
Are these calculators really free?
Yes. Every tool is free to use, with no signup and no account. The site may show ads in the future to support hosting.
Do you store the numbers I enter?
Not by default. Calculations run in your browser, and nothing is stored or sent just by entering numbers. If you choose to create a share link, CommerceKit stores the anonymised snapshot needed to open that shared page.
Can I use these for real purchase decisions?
Use them as a fast sanity check. Always confirm landed cost, duty rates, VAT treatment and MOQ commitments with your accountant, customs broker, and supplier before placing an order.
