Savings Calculator

How our Calculator Works

Understanding how we estimate your potential savings and capacity uplift

Evidence-led estimates The WorkSmart-AI Savings Calculator uses peer-reviewed and public research to estimate how much time, cost, and capacity your organisation could reclaim through staff training on AI.

The calculator has two modes

Both are grounded in real evidence on productivity, task automation, and adoption patterns in higher education.

Standard Calculator

A quick, directional estimate for your whole department.

Advanced Calculator

An optional detailed model that accounts for different academic and professional service roles.

1. The Standard Calculator

A quick, directional estimate for your whole department.

What it shows

Annual savings (£), productivity increase (%), capacity created (FTEs), and five-year projection (£).

How it works

You enter number of employees, average annual salary including typical on-costs such as NI and pensions, and target AI adoption level - basic, intermediate, or advanced.

Core assumptions

1 FTE = 37.5 hours per week × 46 working weeks; on-cost factor is 1.25 × salary; AI-eligible tasks are around 50-55% of total workload; productivity uplift is 5-15% faster completion of eligible tasks depending on adoption level.

2. The Advanced Calculator

A more precise model that accounts for different academic and professional service roles.

What it adds

The advanced calculator allows you to enter headcounts for different academic and professional service roles for a more precise result.

AI-eligible task share

This is the proportion of a person's job made up of activities that AI can assist with directly, such as drafting or summarising text, writing communications or reports, preparing teaching materials, reviewing or analysing data and feedback, searching, referencing, collating information, and formatting or structuring content.

What it excludes

It does not include work that requires in-person teaching, decision-making, or practical delivery that AI cannot (yet) perform reliably.

Role categories and data foundations

When you enter counts for these roles, the calculator replaces the single headcount figure and weights savings by role type, producing a blended productivity and capacity estimate.

Role typeExample departments or functionsTypical AI-eligible task shareRationale
EducatorsTeaching and learning55%Lesson prep, resource creation, and feedback benefit strongly from AI support.
ResearchersResearch staff, postdocs50%Literature review, summarising, and drafting papers show measurable gains.
Educator-ResearchersCombined teaching and research roles53%Balanced mix of academic and administrative tasks.
Library & Learning ResourcesLibrarians, learning developers50%Metadata, summarisation, and research assistance tasks are moderately AI-amenable.

3. Understanding Target Adoption Level

The Target Adoption Level shows how widely and confidently staff are expected to use AI tools in their everyday work. It captures both reach (how many people use AI) and depth (how effectively they use it). High adoption doesn't just mean more licences - it means AI is built into daily workflows.

Adoption levelApproximate adoption rateTypical efficiency upliftExample overall productivity gain
Basic35%8% faster completion0.55 × 0.35 × 0.08 = 1.5% overall
Intermediate60%12% faster completion0.55 × 0.60 × 0.12 = 4.0% overall
Advanced80%15% faster completion0.55 × 0.80 × 0.15 = 6.6% overall

4. KPIs and how the calculator works them out

The calculator produces four key results.

Annual cost savings (£)

Annual savings = Number of staff × Average loaded salary × Productivity improvement.

Productivity increase (%)

Productivity increase = Eligible work × Adoption rate × Efficiency gain.

Capacity created (FTEs)

Capacity created = Number of staff × Productivity increase.

Five-year projection (£)

Five-year savings = Annual savings × 5, or compounded annually if growth is added.

Worked example

Using 12% efficiency on eligible tasks, 60% adoption rate, 55% eligible task share, 60 staff, £45,000 average salary, and an on-cost factor of 1.25:

Productivity improvement = 0.55 × 0.60 × 0.12 = 3.96% (rounded to 4%)
Annual cost savings = 60 × (£45,000 × 1.25) × 0.0396 = £133,650
Capacity created = 60 × 0.0396 = 2.4 FTEs
Five-year projection = £133,650 × 5 = £668,250

Interpreting your results The calculator's figures are directional, not definitive. They illustrate the scale of potential benefit if AI is adopted effectively, supported by training and governance.
