How do you calculate remanufacturing cost?

Multiply returned cores by the reman cost per recoverable core and by the recoverable yield, then add fixed teardown, cleaning, testing, and setup cost. With 1,200 cores at $84, 72% yield, and $9,500 fixed, the variable portion is $72,576 and total cost is $82,076.

Why include a recoverable core yield in the cost?

Not every returned core can be saved. Applying a 72% yield means you only spend full variable cost on the cores that actually move through the line, so cost per usable output reflects scrap and downgrade losses instead of assuming 100% recovery.

What is the cost per core in this example?

Total cost of $82,076 spread across all 1,200 input cores is about $68.40 per input core. Per recoverable core the effective cost is higher because fewer cores survive the yield gate.

Remanufacturing cost vs buying new — how do I compare?

Run this calculator to get reman cost per usable unit, then compare it to the landed cost of a new part. Reman usually wins on parts with high material or casting value (alternators, transmissions, turbochargers) where the core itself carries most of the cost.

What drives remanufacturing cost up the most?

Low recoverable yield is the biggest lever — dropping yield from 72% to 55% raises variable cost sharply because you handle the same cores but salvage fewer. Cleaning chemistry, machining time, and replacement of wear components are the next biggest contributors.

Should the fixed cost be amortized per core?

Yes for unit economics. The $9,500 fixed teardown and setup divided across recoverable cores tells you how much overhead each saved core carries — important when batch sizes are small and fixed cost dominates.

Circular Economy, Recycling & Remanufacturing calculator

Remanufacturing Cost Calculator

Remanufacturing cost is the all-in spend to restore returned cores back to like-new, sellable condition. Reman engineers, core program managers, and aftermarket cost estimators use it to set transfer prices, decide which SKUs are worth reman versus scrap, and defend the business case for a reman line. Because only a fraction of returned cores are actually recoverable, the metric blends a yield assumption into the variable cost so you don't overstate throughput. Getting this number right is what separates a profitable core program from one that quietly bleeds margin on warranty and rework.

What this calculator does

Estimate the total cost to remanufacture returned cores into saleable units, including core volume, cost per recoverable unit, yield allocation, and fixed setup work.
a team needs to price a remanufactured product, set core credit assumptions, or compare rebuild routes for a remanufacturing work order, product family, or quote
It computes total remanufacturing cost as recoverable-core variable cost (cores x cost per core x yield) plus a fixed teardown, cleaning, testing, and setup cost.

Formula used

Recoverable-core variable cost = returned cores released to remanufacturing × remanufacturing cost per recoverable core × recoverable core yield used for this estimate
Total remanufacturing cost = recoverable-core variable cost + fixed teardown, cleaning, testing, or setup cost

Inputs explained

Returned cores released to remanufacturing:
Remanufacturing cost per recoverable core:
Recoverable core yield used for this estimate:
Fixed teardown, cleaning, testing, or setup cost:

How to use the result

Use it when budgeting a reman batch, quoting a reman SKU, or comparing the cost of reman against buying new replacement parts.
It assumes a single blended cost per core and a single recoverable yield; mixed core conditions (A/B/C grade) or escalating rework on low-grade cores can make the real cost higher than this estimate.
