How do you calculate depot repair cost?

Multiply repair orders by the average cost per order and by the chargeable share to get variable repair cost, then add fixed depot overhead. With 96 orders at $740, an 87% chargeable share, and $11,500 overhead, total depot repair cost is $73,304.80.

What does the chargeable repair cost share mean?

It is the portion of repair spend that is billable or recoverable rather than absorbed as warranty or goodwill. The 87% share in the example means 13% of repair cost is non-recoverable, so chargeable variable cost is $61,804.80 before overhead.

Why include fixed depot overhead separately?

Depot facilities, test equipment, and standing labor cost money regardless of volume. Adding the $11,500 overhead to variable cost gives the true total, which is what you must cover to break even on the operation.

What is a good average depot repair cost?

It varies widely by product, but the effective per-order figure matters most. In the example, total cost across 96 orders works out to about $763.59 per order once overhead is spread, slightly above the $740 raw average because fixed costs load onto each order.

Should I repair in-house or outsource?

Compare this total, including the effective per-order cost of roughly $763.59, against a vendor's all-in quote. If a third party beats your loaded depot cost at your volume, outsourcing may free up overhead, but factor in turnaround time and IP control.

How do volume changes affect depot repair cost?

Because overhead is fixed, higher order volume spreads it thinner and lowers the effective per-order cost, while low volume makes each order carry more overhead. This is why the effective per-order figure rises above the raw average at modest volumes.

Aftermarket, Field Service & Service Parts calculator

Depot Repair Cost Calculator

Depot repair cost is the total cost of running your return-to-base repair operation, combining the per-order repair spend that is actually chargeable with the fixed overhead of operating the depot. Aftermarket and reverse-logistics managers use it to price repair contracts, set warranty reserves, and decide between repair, replace, and refurbish strategies. Because depot work mixes variable labor and parts against a heavy fixed-cost base, understanding the blend is essential to quoting profitably. It is also the foundation for benchmarking in-house depot economics against third-party repair vendors.
