How do you calculate repair depot throughput?

Multiply units per cycle by available cycles for gross capacity, then multiply by bench uptime and first-pass yield. With 4 units/cycle over 480 cycles at 90% uptime and 97% yield, released throughput is about 1,676 units.

Why is released throughput lower than gross capacity?

Gross capacity assumes the bench never goes down and every repair passes retest. Here 1,920 gross units lose 192 to downtime and about 52 to retest failures, leaving roughly 1,676 released.

What is a good first-pass repair yield?

For mature ruggedized repair lines, first-pass yield above 95% is strong. At 97% the retest loss is small, about 52 units in this example, but every point below that compounds against throughput.

How does bench uptime affect throughput?

Uptime scales gross capacity directly. Dropping from 90% to 80% in this scenario would cut roughly 190 more units, since downtime removes capacity before yield is even applied.

Should I use this for turnaround time commitments?

Use it to set the volume you can release per planning period, then divide your inbound backlog by that throughput to estimate realistic turnaround, rather than promising against gross capacity.

Does this account for reworked units that eventually pass?

No. First-pass yield removes units that fail retest, giving a conservative figure. If your depot reworks and re-releases most of those, actual released volume sits above this number.

Defense Electronics & Ruggedized Systems calculator

Repair Depot Throughput Calculator

Repair Depot Throughput estimates how many ruggedized electronics units a depot actually releases back to the field after accounting for bench uptime and first-pass repair yield. Sustainment planners and depot managers use it to set realistic turnaround commitments instead of quoting the gross bench capacity that downtime and retest losses never deliver. Defense repair lines lose units to bench downtime and to repairs that fail retest and need rework, so gross capacity always overstates real output. This calculator strips out both losses so your throughput number matches what the warfighter will see.

What this calculator does

Estimate repair depot capacity for field-returned rugged electronics, mission computers, radios, power supplies, sensors, or replaceable modules.
Use it when repair depot throughput in defense electronics and ruggedized systems is being asked to take on more work and you need to know if there is room.
It multiplies units per cycle by available cycles to get gross capacity, then derates that by bench uptime and first-pass repair yield to give released throughput.

Formula used

Gross depot repair capacity = units repaired per depot cycle × available depot repair cycles
Released repair depot throughput = gross depot repair capacity × expected repair bench uptime × first-pass repair yield

Inputs explained

Units repaired per depot cycle:
Available depot repair cycles:
Expected repair bench uptime:
First-pass repair yield:

How to use the result

Use it when committing depot turnaround volumes, sizing repair staffing, or quantifying how much downtime and rework cost you in released units.
First-pass yield here removes units that need rework rather than recovering them; if your process reworks and re-releases failed units, actual released volume will be somewhat higher than this conservative estimate.

Current U.S. benchmarks

The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).
