How to Amortize Fixture and Jig Costs
The core of amortizing fixture and jig costs is to spread the one-time investment across the unit price of each part. There are three common approaches: including the cost in the unit price, listing tooling fees separately, or recovering the cost over multiple orders based on order volume. When requesting a quote, buyers should first clarify order volume, product complexity, and whether the fixtures can be reused, then agree on the amortization method with the CNC machining supplier to avoid additional charges later.
Why Fixture Costs Need Separate Discussion
Fixtures and jigs are non-standard expenses, and design complexity and material costs vary greatly from project to project. If these costs are hidden directly in the unit price, buyers will find it difficult to judge whether the pricing is reasonable. Listing fixture costs separately and agreeing on an amortization method makes the quote transparent and facilitates comparison of terms across different suppliers. For OEM and prototyping development teams, this is a critical step in controlling initial investment and mass production costs.
Three Common Amortization Methods
Included in Unit Price
The fixture cost is spread evenly across each quoted part. This suits mass production with stable order volumes and requires no upfront payment.
Tooling Fee Listed Separately
The fixture cost is quoted independently and paid with the first order or deducted in installments. Subsequent unit prices are lower, making this suitable for long-term cooperation.
One-Time Quote
For prototyping or small batches, the fixture cost is not recovered and is absorbed by the machining supplier, but the unit price will be higher.
Information Buyers Should Prepare Before Requesting a Quote
Buyers are advised to first compile estimated annual usage, order quantity per batch, product tolerances and complexity, and whether the fixtures need to be shared across multiple part types. This information directly affects the amortization method the machining supplier recommends. Providing 3D drawings and material specifications also helps improve quote accuracy.
