How to build an evidence-aware return-on-investment forecast for a training or development program — step by step.

Cahill Consultants LLC Informed by the Phillips ROI formula · Forecast planning model
01 What this tool does

The calculator turns your program's costs and expected outcomes into an auditable forecast — led by a Year-1 ROI and a multi-year range — then adjusts every benefit for attribution, evidence confidence, population and realizable economic value.

It is informed by the Phillips ROI formula and is compatible with planning for Kirkpatrick Level 3 behavior and Level 4 results. Importantly, this is a forecast planning model — it estimates ROI before a program runs; it does not observe evidence or measure delivered results.

The defining move is credibility adjustment, applied to each benefit individually:

  • Population — only the learners who reach the right stage (attended → completed → applied) count toward a behaviour-change benefit.
  • Isolation — the share of the outcome the training truly caused.
  • Confidence — how sure you are of the estimate.
  • Cashability — how much of the value becomes usable money (freed-up time isn't automatically cash).

The result is shown as a conservative–expected–optimistic range. It remains a planning range, not a statistical confidence interval.

02 Before you start — gather these

You can use the built-in example to explore, but for a real estimate have rough figures ready for:

  1. Program name and how it's delivered (classroom, virtual, eLearning, or blended). For instructor-led: learners per cohort and cohorts per year. For eLearning: total annual enrollment.
  2. How many years the program (and its benefits) will realistically last.
  3. Average salary and benefits load of the employees being trained — used to price their time.
  4. Build costs (one-time): analysis, instructional design, development, media, technology, and evaluation.
  5. Delivery & running costs: facilitator, facilities, materials, hosting, administration, maintenance — plus, optionally, the itemized costs training cases usually miss (project management, accessibility, learner support, AI licenses, and more).
  6. The outcomes you expect to move — fewer errors, faster ramp-up, lower turnover, more sales, etc. — with a rough size for each, and a sense of who realizes each one (everyone trained, only those who apply it, or an independent outcome count).
  7. Optional but powerful: your participation rates (how many start, complete, and apply the training) and, per benefit, its isolation, confidence and cashability.
Don't have exact numbers? Use the built-in example only to learn the workflow. For a real case, document the source and owner of every enabled benefit; unsupported percentages are assumptions, not evidence.
03 Step-by-step

The calculator moves through six tabs. Your results update live in the panel on the right as you type.

STEP 1 Scenario

Describe the program and the workforce it affects.

  • Delivery modality comes first — it reshapes the cost inputs on the next tab. Pick how the program is delivered (see the four options below).
  • Scale — for instructor-led modes this is learners per cohort × cohorts per year; for eLearning it's a single total annual enrollment instead.
  • Lifespan is how many years the program and its benefits realistically last. Discount rate is used for Net Present Value; use your organization's finance-approved hurdle or discount rate rather than treating the example value as a benchmark.
  • Burdened labor cost — salary × (1 + benefits %) ÷ working hours — is the fully-loaded hourly cost of an employee. The tool computes it and uses it to price training time and productivity gains.

The four delivery modalities — each changes which delivery costs and time figures apply:

Classroom (in-person ILT)Cohort-based. Full delivery costs: facilitator, facility, A/V, materials, travel, plus each cohort's classroom time.
Virtual ILT (live online)Cohort-based like classroom, but no facility and no travel — just facilitator, platform/A/V, materials, and learner time.
eLearning (self-paced)No cohorts and no facilitator. You enter total annual enrollment and the completion time each learner spends. Cost is per-seat hosting plus learner time — so cost per learner falls sharply as enrollment grows.
Blended (ILT + self-paced)Cohort-based classroom or virtual delivery (you pick which) plus a self-paced component; the self-paced minutes are added to each learner's time.
Completion no longer discounts everything. Earlier the tool applied one blanket completion rate to all benefits. Now completion lives in the participation funnel (Step 2, advanced) and only affects the benefits you tie to a funnel stage — because completing a course isn't the same as applying it, and an outcome like "incidents avoided" shouldn't be discounted by it at all.

STEP 2 Costs

Enter every cost, so the investment side is fully loaded (conservative):

  • One-time build — needs analysis, instructional design, SME time, development, graphics, video, translation, technology setup, and evaluation & measurement. Counted once, up front — a one-time investment at launch (not spread across the years).
  • Delivery (recurring)this section changes with the modality you chose in Step 1. Instructor-led shows facilitator, facility, A/V, materials, travel, and hosting per cohort; eLearning replaces those with per-seat hosting. Fields that don't apply are hidden automatically.
  • Maintenance — enter a direct annual amount (recommended), or estimate it as a % of your authored content only. Add a major content refresh ($ every N years) if you plan one.
  • Administration / coordination — the annual overhead of running the program.
Participant time is added for you. It's usually the single largest — and most often forgotten — training cost, and it's an opportunity cost (time redirected from work), not a cash outlay. Attendees are counted at full training time; self-paced non-completers only for the hours you say they spend.

Advanced / itemized costs (optional) — expand this to add the costs training business-cases most often miss: project/program management, pilot & QA, accessibility, change management, fixed platform licenses, learner support, ongoing evaluation, reinforcement/coaching, backfill/overtime/temporary coverage, vendor delivery, facilitator prep & travel, assessment/certification, and a full set of AI-related costs. Each field is tagged with when it applies (one-time, annual, per cohort, or per learner) and what kind of cost it is (cash, opportunity, or overhead).

Watch for double counting. If you include both participant opportunity cost and backfill/overtime, or both facilitator wages and vendor delivery, the calculator flags the combination. Keep both only when they are genuinely separate, incremental costs.

Advanced participation funnel (optional) — set the share of enrolled learners who start / attend, complete, and apply the training. These default to 100%. Lowering them scales the benefits you tie to each stage (Step 3) and prices non-completer time honestly.

STEP 3 Benefits

Switch on only the outcomes this program will genuinely move, and size each one. Options include error/rework reduction, productivity gains, faster new-hire ramp-up, retention, safety & compliance, reduced supervision, sales lift, customer retention, and support-ticket reduction.

Every benefit now carries its own credibility settings, so you're not forced to apply one blanket assumption to unrelated outcomes:

  • Counts toward — which population realizes it: Enrolled, Started/Attended, Completed, Applied on the job, a Custom count you've already scoped, or an Independent outcome (like incidents avoided) that the funnel should not discount. Behaviour-change benefits default to Applied; outcome counts default to Independent.
  • Attribution, confidence & cashability (a small panel on each benefit) — set that benefit's own isolation %, confidence %, a cashability class and realized %, and a source and owner for the record. Leave isolation/confidence blank to inherit the defaults from Step 5.
Cashability matters most for "capacity released" benefits. Time freed up is only real money if it's redeployed to valued work — so for productivity-style benefits, set a realistic realized %, not 100%.
Less is more. Two or three well-estimated, well-attributed benefits are far more credible than nine optimistic ones.

STEP 4 AI impact (optional)

Model AI on both sides of the ledger — honestly:

  • Upside — lower build cost from AI-accelerated development, plus productivity from AI performance support and AI-adoption training. The development saving only reduces the AI-eligible authoring labor (instructional design, development, graphics, video) — never needs analysis, translation, technology setup or evaluation.
  • Downside — if you claim AI benefits, add the AI-related costs in Step 2's advanced section (licenses, usage, integration, governance/security, human review, error correction/rework, monitoring, vendor implementation). The tool will flag a one-sided AI case that shows only the upside.

Leave all of this off for a classic, no-AI ROI case.

STEP 5 Timing, persistence & scenario

These settings shape how the forecast plays out over time and how wide the range is:

  • Default isolation & confidence — the starting values every benefit inherits unless you override it in its own panel (Step 3).
  • First-year realization and first-year cost ramp — how much of the benefits and of the recurring costs actually land in year one (a program rolling out across the year rarely hits 100% of either on day one).
  • Benefit persistence after Year 1 — how much of each year's benefit carries into the next. Defaults to 100% (no decay); lower it, with a stated rationale, if skills fade without reinforcement. This only affects the multi-year projection — never the Year-1 number.
  • Scenario swings — how benefit magnitude, application, isolation and volume-driven costs could move. The report turns these into a Conservative–Expected–Optimistic planning range. Confidence stays fixed because it is already captured per benefit.
Example: a raw benefit of 100 at 75% isolation × 85% confidence counts as 63.75 before population and realizability are applied. The percentages must still be supported by a source and accountable owner.

STEP 6 Report

A clean, printable summary built for a finance audience:

  • Year-1 ROI as the headline (the most defensible single number), with the multi-year range beneath it.
  • "How each benefit is built" — the full equation for every benefit (raw × isolation × confidence × population × cashability = adjusted), in plain language, with each one's source and owner.
  • Cost by type — cash outlay vs. opportunity (time) vs. allocated overhead, so nobody mistakes freed-up time for cash.
  • Cost and benefit breakdowns, cumulative net economic value, your key assumptions, an evidence-readiness register, plausibility flags, and potential intangibles to investigate.

04 Reading the results

The numbers, and what each one answers.

MetricWhat it tells youHow it's found
Year-1 ROI (headline)The most defensible number: first-year return on first-year investment. Often modest — a big upfront build rarely pays back inside year one, and that's honest.(yr-1 benefit − yr-1 cost) ÷ yr-1 cost
Multi-year rangeConservative / Expected / Optimistic ROI across the program's life, from your scenario swings. A range, not false precision.expected ± swings
Benefit-Cost RatioBenefits per dollar of cost. 1.5:1 means $1.50 back for every $1 spent.benefits ÷ costs
Economic paybackWhen cumulative modeled economic value recovers the investment, within the entered lifespan.cumulative net economic value crossing
Economic NPVToday's value of future modeled economic benefits and costs. It may include non-cash capacity and opportunity costs.Σ net economic value ÷ (1+r)ᵗ
A note on honesty: a fully-loaded, well-adjusted program often lands at a lower ROI than a napkin estimate — and that lower number is the one that gets funded, because it holds up. Lead with Year-1; use the multi-year range to show the upside without overpromising.

06 Glossary
Year-1 ROIFirst-year return on first-year investment — the report's headline and most defensible number.
Burdened hourly costThe true hourly cost of an employee, including benefits — used to price time spent training or saved on the job.
Fully-loaded costEvery cost of the program, direct and indirect, including participant time and overhead. The Phillips ROI approach emphasizes this for a conservative, defensible figure.
Participation funnelEnrolled → Started/Attended → Completed → Applied. Each stage is a smaller group; benefits are tied to the stage that truly realizes them.
Population basisWhich group a benefit counts toward — a funnel stage, a custom count, or an independent outcome that the funnel shouldn't discount.
IsolationThe portion of a result attributable to the training specifically, separated from other influences. Set per benefit.
ConfidenceYour certainty in an estimate, applied as a discount. Set per benefit.
CashabilityHow much of a benefit becomes usable money. Freed-up time ("capacity released") only counts if it's redeployed to valued work.
Opportunity costEmployee time redirected from work — a real cost, but not a cash outflow. Reported separately from cash and overhead.
PersistenceHow much of a benefit carries from one year into the next. 100% = no decay; lower it with a stated rationale.
Scenario rangeConservative / Expected / Optimistic results derived from your swings on benefits and variable costs — shown instead of a single number.
IntangiblesPotential benefits not converted to dollars — engagement, brand, morale — listed as candidates to investigate, not claimed results.
Economic NPVFuture modeled economic benefits and costs restated in today's dollars using the discount rate; not necessarily literal cash flow.
