Aftermarket, Field Service & Service Parts calculator
Service Dispatch Cost Calculator
Service dispatch cost is the fully loaded spend of getting a field technician to a customer site, combining the variable cost of each truck roll with the fixed cost of running a dispatch desk. Field service managers and aftermarket P&L owners use it to decide which calls to recover through warranty or service contracts versus absorb. Because a single avoidable dispatch can wipe out the margin on a spare-parts order, knowing the true per-call and total figure is what separates a profitable service operation from one that bleeds on every callout. It is the number you bring to the table when negotiating SLAs or justifying a remote-support investment.
What this calculator does
- Estimate dispatch cost from dispatched service calls, dispatch cost per call, chargeable share, and fixed scheduling overhead.
- a dispatch or service operations manager needs to estimate the cost of coordinating field service calls
- It computes the recoverable variable dispatch cost across your call volume and adds fixed scheduling overhead to give a total burdened service dispatch cost.
Formula used
- Recoverable dispatch cost = dispatched calls × dispatch cost per call × recoverable dispatch share
- Service dispatch cost = recoverable dispatch cost + fixed scheduling overhead
Inputs explained
- Dispatched service calls:
- Dispatch cost per call:
- Recoverable dispatch share:
- Fixed scheduling overhead:
How to use the result
- Use it when budgeting a service period, pricing a maintenance contract, or building the case for remote triage that deflects truck rolls.
- It treats per-call cost as a flat average; long-distance or after-hours dispatches with travel premiums and overtime will be understated unless you segment them.
Common questions
- How do you calculate service dispatch cost? Multiply dispatched calls by the cost per call and by the recoverable share, then add fixed scheduling overhead. With 520 calls at $48, an 85% recoverable share, plus $7,200 overhead, recoverable variable cost is $21,216 and total dispatch cost is $28,416.
- What is the difference between recoverable dispatch cost and total dispatch cost? Recoverable dispatch cost ($21,216 here) is only the variable portion you can bill back or recover through contracts. Total dispatch cost ($28,416) adds the fixed scheduling overhead you pay regardless of call volume.
- Why is the effective cost per call higher than the input rate? The input rate of $48 is variable only. Once you spread the $7,200 fixed overhead across 520 calls, the fully burdened cost per call rises to about $54.65, which is the figure that should inform pricing.
- What is a good service dispatch cost per call? It varies by trade, but burdened figures of $40 to $80 per call are common for light field service. The goal is to drive total cost down by lifting recoverable share and deflecting low-value calls to remote support.
- How can I lower my dispatch cost? Increase first-time-fix rate, raise the recoverable share through better contract attach, route smarter to cut windshield time, and resolve simple cases remotely so fewer of the 520 calls become truck rolls.
- Does this include parts and labor on site? No. This models the dispatch and scheduling cost of getting a tech moving. On-site labor, parts, and materials should be costed separately and added to your full service cost of delivery.
