Your assumptions, visible

Calculate the training scenario.

Include software, setup and the time costs you want to measure. Contribution per job should reflect the delivery and selling costs included in your model. The attribution percentage is your assumption, not a measured causal result.

Complete the four inputs to see the result.

A training program can look inexpensive until the manager’s review time is included. It can also look expensive while freeing time for a more valuable coaching conversation. To compare the options, count the work consistently and keep expected benefits separate from results you have observed.

Use the interactive model above to explore a training scenario. This guide then compares two approaches using a worked cost model. It does not promise a retention lift, a fixed ramp time or a return from switching software. For an interactive starting point, open the ROI calculator and replace the example inputs with your own.

Next Step

Separate training ROI from real-time coaching ROI

Training delivery and in-conversation coaching have different adoption, attribution, manager-time, and compliance costs. Model the coaching intervention separately before comparing the results.

Compare the same training job

Start with the task: preparing new reps for retail consultations, improving a recurring price explanation, or helping managers review field appointments. Keep the audience, period and objective the same in both cases.

If the current program includes manager demonstrations, ride-alongs and practice, write down which activities would continue with AI support. Do not put the entire current program on one side and only a software invoice on the other. Technical instruction, field support and management still require time.

Separate setup from recurring work

Setup includes preparing company material, choosing scenarios, configuring the supported workflow and helping the first group use it. Recurring work includes practice, session review, feedback and updates to the material.

Record who performs each activity and how long it takes. Use actual time where available. When estimating, label the assumption and revisit it after the first cycle. A short period with unusually heavy setup should not be presented as the steady-state cost of the program.

WorkCurrent approachApproach being tested
Product and process instructionWho teaches and maintains it?What still needs the same qualified instruction?
Conversation practiceWho participates and provides feedback?Which attempts use AI and which use a manager?
Field reviewHow does the manager learn what happened?How are recordings and coaching notes reviewed?
Follow-upWhat happens after feedback?How is the next attempt checked?

Worked cost comparison

These are hypothetical planning inputs. They are not industry averages or measured GhostRep savings. Suppose a team evaluates a month of training with manager time valued at $50 per hour and rep time at $25 per hour. Both approaches use 40 total rep hours.

Cost inputCurrent approachTest approach
Manager time30 hours × $50 = $1,50024 hours × $50 = $1,200
Rep time40 hours × $25 = $1,00040 hours × $25 = $1,000
Software attributed to period$100$300
Setup attributed to period$0$200
Total modeled cost$2,600$2,700

The test approach costs $100 more in this example and uses six fewer manager hours. That is not a cash-saving claim. The manager may use those hours for field support or coaching, but the value depends on what actually happens. If setup does not recur, model the following period separately rather than hiding the first-period expense.

Add outcomes only after defining them

If the goal is better proposal explanations, use a behavior-based review. If it is faster readiness, define the tasks a rep must demonstrate. If it is business performance, choose the completed and collected outcomes you will compare.

A higher practice score is useful feedback, but it is not automatically an additional job. A faster first sale can reflect a different lead source. Use the training ROI guide to connect program cost to attributed contribution while keeping that uncertainty visible.

Test the assumptions that change the decision

Run a case where manager review takes longer than expected. Run another where reps use fewer sessions. Check what happens if the additional jobs you hoped to see do not appear during the evaluation period.

Sensitivity is useful because adoption and review time are often easier to observe than long-term revenue impact. If the program requires participation the team cannot sustain, a favorable spreadsheet is not enough. Reduce the scope or change the workflow before extending the rollout.

What should a manager review?

Choose a specific exchange from an appointment rather than asking the rep to summarize the entire visit. In Echo, the recording and transcript support that review. Discuss the customer’s question, the rep’s response and one change for the next attempt.

Use AI Role Play when the rep needs another chance to explain the same idea. A useful scenario varies the customer’s concern while preserving the skill being practiced. The manager should be able to say what improved and what still needs work.

For a recurring team issue, prepare a short session through Training Studio. Keep the company’s current product and sales material close to the lesson so feedback stays specific.

Keep retention out of the model until you have evidence

Turnover has several possible causes, including role expectations, compensation, management, workload and personal circumstances. Training may be part of the experience, but a universal retention improvement is not a sound input.

Record actual departures and the context the company can establish. If a longer evaluation supports a retention benefit, describe the cohort and period. Do not multiply an assumed percentage by a large replacement-cost estimate and present the result as money already saved.

Make a practical decision

At the end of the evaluation, compare the original task with the work delivered. Did managers get useful evidence? Could reps apply the feedback? Were the setup and review demands manageable? Did the cost remain reasonable when optimistic assumptions were reduced?

Use those answers to continue, narrow or stop the program. Preserve the cost worksheet and review notes so the next decision starts from observed use rather than a new set of promises.

What does GhostRep cost?

The published bundles are 25 hours for $200, 100 hours for $600 and 250 hours for $1,000. Keep purchased capacity, usage during the period and internal time costs distinct in your comparison.

Can AI replace the manager’s training work?

It can support practice, live coaching and review. The manager still sets the standard, checks company-specific explanations and decides what the team should work on next.

When should we calculate ROI?

Define the model before the pilot, then update it with observed costs and outcomes. Report preliminary results as preliminary when jobs or other outcomes have not matured.
