Where do the default values come from?

They are illustrative numbers so each page shows a worked answer. Replace them with your own RMA and test logs, bench times, quotes, contract terms and the targets in your depot plan.

Why do some results show a warning?

A warning means the plan fails a limit you entered or one from a cited source, such as a diagnosis cost above the evaluation fee or burn-in racks short of the week's plan. The message states the gap and what to change.

Can I download the calculation?

Yes. Every calculator has an Excel workbook with live formulas that match the page, so you can check the math or reuse it in a quote.

Why is a result blank?

An input is missing or outside its valid range, so there is no honest number to show. The message above the result names the input to fix.

Best calculators in this category

Diagnostic Labor Cost: Labor cost of diagnosing returned units from triage and full diagnostic times, per unit and against your evaluation fee.
First-Pass Repair Yield: Share of repaired units that pass final test the first time, against your target, with the rework hours the failures take.
Board Rework Time: Technician hours a batch of board reworks needs, from rework and inspection minutes per board, against the bench hours scheduled.
Parts Salvage Value: Net value of parts harvested from scrap or returned boards after test, against the labor to remove and test them.
Burn-In Test Capacity: Units the burn-in racks can test each week from slots, cycle time and rack downtime, against the week's plan.
RMA Queue Lead Time: Days an RMA takes from receipt to shipment from the queue, the daily completion rate and hold days, against the turnaround target.
No-Fault-Found Rate: Share of diagnosed returns where no fault was found, against your maximum, and the diagnostic cost those returns carry.
Electronics Warranty Reserve: Warranty reserve the units still under cover need, from a finished batch's claim rate and the cost per claim, against the reserve booked.
Refurbish vs Replace Decision: Repair cost as a share of replacement cost, counting repeat failures, against your beyond economic repair threshold.
Cost per Repaired Unit: Full cost of a repaired unit from bench labor, parts and its share of depot overhead, against your target cost.
Component Replacement Cost: Cost to replace failed components across a batch of boards, labor included, against swapping each board for a replacement.
BGA Reball/Reflow Labor Cost: Cost of BGA reball and reflow rework for a batch of boards, counting boards lost when rework fails, per good board recovered.
