Construction landed-cost calculator specification
A landed-cost calculator specification lists the inputs needed to turn a factory price into a delivered cost per unit. Use the tool with your own figures; it holds no rates.
This page specifies what a landed-cost calculator for construction materials should capture, and gives you a simple one to use. Landed cost is the full cost of having goods at your site, not the factory price. The tool adds your entries for unit price, freight, duties, insurance and local handling and shows a total and a per-unit figure. It contains no rates.
Inputs the calculator needs
| Input | Notes | Source |
|---|---|---|
| Quantity and unit | Pieces, sheets, tonnes, square meters | Your takeoff |
| Unit price and currency | State the Incoterm and validity date | Supplier quotation |
| Packing and loading | May be excluded from ex-works prices | Supplier |
| Freight | Origin to port or site; container or truck basis | Forwarder quote |
| Insurance | Cargo cover during transit | Insurer or forwarder |
| Duties and taxes | Depend on classification and country | Customs broker or authority |
| Port, clearance and inland transport | Handling at destination | Broker, carrier |
| Local handling and storage | Unloading, crane, site storage | Contractor |
| Exchange rate | Record date and source | Your bank |
Formula
Landed total = unit price x quantity + freight + insurance + duties and taxes + clearance + local handling. Landed cost per unit = landed total / quantity. Keep currency conversion as an explicit step so you can see its effect separately.
Use the calculator
Enter each line for one shipment or material package. If you are comparing suppliers, run it once per quote with the same quantity and the same basis. Make a note of which items are estimates.
Common traps
- Comparing an ex-works price with a delivered price. The Incoterm tells you where cost and risk transfer.
- Leaving out packing, port charges and inland transport.
- Assuming duties without checking classification with a customs broker.
- Using an exchange rate from quote date for a payment months later.
- Forgetting wastage and damage allowance, which sits in your quantity, not the unit price.
The factory-price comparison is explained further in how to compare delivered cost with factory price, and the sourcing trade-offs in local vs imported materials.
Limits
This is an estimating aid. Duties, tax treatment and import rules are set by authorities and change, so confirm with a customs broker and the official authority before committing to an order.
Questions people ask
What is landed cost?
The total cost of getting goods to your site: unit price plus freight, insurance, duties, taxes, handling and any other delivery charges.
Which Incoterm should I use?
That depends on who you want to carry freight and risk. Agree the term in the quotation and check the current ICC Incoterms rules.
Where do I find duty rates?
From your customs authority or a licensed customs broker. This page does not provide rates.
Why divide by unit?
Per-unit landed cost lets you compare suppliers with different pack sizes, freight terms and currencies.
