Core Recovery Rate at 49% target core recovery rate: a worked example

This worked example runs the core recovery rate numbers for a tougher week than the baseline: 49% target core recovery rate instead of the typical 68%. Calculate the share of sold or eligible products that return as usable cores for remanufacturing.

The inputs for this scenario

  • Usable cores returned: 1,380 cores (held at the documented default)
  • Eligible cores expected from sold units or service population: 2,100 cores (held at the documented default)
  • Target core recovery rate: 49 % (the input this scenario stresses; the baseline uses 68)

Working through the calculation

  • The calculation starts from the formula this tool documents: Core Recovery Rate = usable cores returned ÷ eligible cores expected from sold units or service population × 100.
  • Core Recovery Rate result works out to 65.71 % at these inputs, and this is the headline figure for the scenario.
  • Core Recovery Rate gap to target works out to -16.71 points at these inputs.
  • Usable cores returned works out to 1,380 count at these inputs.
  • Eligible cores expected from sold units or service population works out to 2,100 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target core recovery rate sits at 68% and the headline result is 65.71 %, this scenario lands almost exactly on the baseline at 65.71 %.
  • Use it when reviewing core program health, setting or adjusting core charges, or diagnosing why a reman line is short on cores. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Core Recovery Rate result: 65.71 % (headline result)
  • Core Recovery Rate gap to target: -16.71 points
  • Usable cores returned: 1,380 count
  • Eligible cores expected from sold units or service population: 2,100 count
