Calculate your truck roll costs
Start with monthly troubleshooting dispatches and the cost of each visit. Adjust the share you believe could be resolved without attendance, then compare three possible reductions side by side.

A truck roll is a field technician or engineer visit. Start with the number of reactive visits in a consistent period, then estimate the cost you incur for each visit. The result gives you a modelled baseline for the cost of dispatching engineers.
Next identify the share of visits that might be resolved remotely. This is an assumption until verified against your service data. The three reduction scenarios apply only to that eligible group; they do not imply that all visits can safely be removed.
The formula
Annual dispatch cost = monthly reactive visits × cost per visit × 12.
Eligible annual cost exposure = annual dispatch cost × potentially avoidable share.
Potential annual gross savings = eligible annual cost exposure × selected prevention scenario.
The Conservative, Standard and Aggressive settings assume that 20%, 35% or 55% of potentially avoidable dispatches could be prevented. They are editable planning scenarios, not performance claims.
| Input or calculation | Value |
|---|---|
| Reactive dispatches | 500 |
| Modelled cost per dispatch | £220 |
| Annual dispatch cost | £1,320,000 |
| Potentially avoidable share | 20% (assumed) |
| Eligible annual cost exposure | £264,000 |
| Standard reduction of eligible visits | 35% (assumed) |
| Potential annual gross savings | £92,400 |
Example: 500 × £220 × 12 = £1,320,000. Of that, 20% is assumed potentially avoidable (£264,000). A 35% reduction of the eligible group produces £92,400 in modelled annual gross savings. Actual results require validation.
What does a truck roll actually cost?
There is no single dependable price for every engineer dispatch. Build your internal cost from the time and expenses associated with one visit, then separate costs that would disappear from capacity you could redeploy. A customer call-out charge is not necessarily the cost to your operation.
Technician labour, including travel
Include fully loaded technician time for the return journey, on-site diagnosis and job administration. If the technician remains on payroll, fewer visits may free capacity without automatically reducing cash spending.
Vehicle, mileage and travel costs
Count relevant fuel or charging, parking, tolls and marginal vehicle costs. Use your own expense or fleet data. Mileage tax allowances in the UK or US are not universal benchmarks for the cost of running a field-service fleet.
Scheduling and dispatch administration
Allow for scheduling, customer confirmations, case updates and other work that really disappears if the site visit is prevented. Do not allocate the same administrative costs twice.
Repeat call-outs and additional technicians
A second site visit is another dispatch, even when it belongs to the same customer issue. Include each actual attendance once. If a job needs two engineers, use the combined labour cost rather than assuming a single technician.
Costs that do not disappear
Fixed salaries, leases and other committed expenses do not become immediate cash savings just because fewer visits take place. Treat the benefit as released capacity unless expenditure, overtime or contractor usage actually changes.
Truck rolls and engineer call-outs: UK and US terminology
The service is similar; the search terms change. US teams typically discuss truck rolls and technician dispatch costs. UK teams often discuss engineer call-outs, engineer visits or site attendance. Use your own operating figures in either currency, not an invented international average.
US: truck roll or technician dispatch
A truck roll normally means one technician or crew attendance at a customer site. Count individual visits rather than tickets: a job requiring two separate attendances produces two truck rolls.
UK: engineer call-out or site visit
An engineer call-out is the corresponding on-site attendance. A published call-out fee or the amount invoiced to a customer is a price, not necessarily the full internal cost of deploying the engineer.
UK cost inputs
Use pounds, fully loaded engineer time, round-trip travel and vehicle expenses. HMRC publishes approved mileage allowances for eligible private-vehicle business travel; those are tax-reference rates, not a universal fleet-cost figure.
US cost inputs
Use dollars, technician or crew hours, drive time, vehicle costs and scheduling overhead. The IRS business mileage rate is a reference for vehicle business use, not a benchmark for the entire truck roll. Changing the calculator currency only changes the symbol, not the underlying amount.
How to reduce unnecessary truck rolls
A lower dispatch count only matters if the original problem is resolved and customers do not need to contact you again. Review the visit types first, introduce appropriate remote checks, and measure completed resolutions rather than assuming every avoided booking is a saving.
Identify the right problems for remote diagnosis
Review the last 60–90 days of reactive dispatch records. Note the reported fault, work completed, no-fault outcomes and repeat visits. Exclude installations, safety-critical attendance and work requiring a qualified engineer.
See the issue before dispatch
When appropriate, ask customers to show accessible equipment, indicators or the problem environment through live video. Grypp helps an agent confirm what is visible instead of relying entirely on verbal descriptions.
Guide a safe check and confirm the outcome
Use screen sharing or co-browsing for supported digital steps, or guide simple physical checks that customers can safely perform. Confirm that the underlying service or device works before closing the interaction.
Measure genuine engineer visits avoided
Track completed remote resolutions for eligible incidents, any follow-up contacts or repeat dispatches, and costs that were actually removed. When attendance is still needed, pass visual findings to the field team so the visit starts with better context.
Truck roll cost FAQs
Clear answers about engineer call-outs, avoidable dispatches and how to interpret your savings estimate.
What is a truck roll or engineer call-out?
A truck roll is an on-site technician or engineer visit. In the UK, it is commonly called an engineer call-out or site visit. Count each separate attendance once, even when several visits relate to the same customer issue.
How much does a truck roll cost in the US or UK?
There is no universal average. Internal cost depends on labour, travel, vehicles and dispatch administration. A customer-facing call-out fee is not necessarily the cost of providing the visit. Use your own figures in USD or GBP.
How can I identify potentially avoidable truck rolls?
Review reactive dispatch records for jobs that might have been resolved through safe remote diagnosis or guidance. Exclude visits requiring physical repair, qualified attendance or mandatory safety checks. Verify outcomes and repeat visits before treating cases as preventable.
How are the savings scenarios calculated?
Each scenario assumes a different proportion of potentially avoidable visits can be prevented. The visit eligibility rate is your own estimate. These are planning scenarios, not guaranteed Grypp results.
Do avoided engineer visits always create cash savings?
Not automatically. Fewer journeys may reduce fuel, contractor or overtime spending, while salaried engineering time may become available for other work. Compare genuine avoidable expenditure with the additional costs of remote support.

Methodology and assumptions
Method: Use reactive troubleshooting and repair visits, not planned installations or mandatory attendance. Annual dispatch cost = monthly visits × modelled avoidable cost per visit × 12. Eligible annual cost = annual dispatch cost × estimated avoidable share. Potential gross savings = eligible annual cost × selected prevention assumption. Use separate labour, vehicle and administrative costs in Advanced mode. Avoid double-counting repeat visits, labour and shared overheads.
Assumptions and interpretation: Scenario prevention rates are illustrative, not measured Grypp outcomes or universal benchmarks. Gross savings may include redeployable capacity and exclude remote-support, implementation and technology costs. The currency selector does not perform foreign-exchange conversion. Regional reference: HMRC mileage allowances and IRS mileage rates concern specified vehicle/business-use calculations, not total engineer dispatch costs.
