AI Investment ROI Model

Will Finance and the board approve this AI investment?

Build a board-ready AI business case with NPV, IRR, payback period, and benefit-cost ratio — across three scenarios, with sensitivity analysis. The output Finance actually approves.

The Problem

A business case that Finance does not recognise is not a business case.

Most AI ROI estimates are optimistic single-scenario calculations that ignore total cost of ownership, risk-weight benefits, or produce metrics that CFOs do not use. They get sent back. This one does not.

💵

No standard financial metricsTeams produce "savings estimates" without NPV, IRR, or payback period — the metrics Finance and the board actually use to approve investment.

🎲

Single-scenario optimismA best-case ROI figure does not survive a board challenge. You need a conservative case, a base case, and a stretch case — with the same rigour in all three.

📈

Benefits not risk-weightedClaimed AI benefits (productivity gains, error reduction, revenue uplift) are often accepted at face value. Finance applies a risk discount. You should too.

📋

TCO not modelledTotal cost of ownership — including ongoing inference, retraining, MLOps, and change management costs — is routinely understated or excluded entirely.

How It Works

The scoring framework.

Ten tabs. Three scenarios. The full set of financial metrics a CFO or investment committee expects to see.

Investment InputsOne-time and recurring costs: build, infrastructure, licensing, training, change management

Benefit ModellingRevenue uplift, cost avoidance, productivity gain — each risk-weighted and time-profiled over the investment horizon

Three-Scenario ModelConservative, Base, and Stretch cases modelled independently — same structure, different assumptions

NPV / IRR EngineNet Present Value and Internal Rate of Return calculated per scenario using your organisation's discount rate

Sensitivity AnalysisIdentify which input variables drive the biggest swing in ROI — cost overrun, benefit realisation delay, adoption rate

Key Term

Governance Gate: A staged funding checkpoint where an initiative must justify continued investment before proceeding to the next phase — the decision this business case is built to support.

Frequently Asked

Questions buyers ask before building their business case.

What financial metrics does the AI Investment ROI Model produce?

Net Present Value (NPV), Internal Rate of Return (IRR), payback period, and Benefit-Cost Ratio (BCR) — calculated across a conservative, base, and stretch scenario, with sensitivity analysis showing which assumptions most affect the outcome.

How is this different from a simple ROI calculator?

A simple ROI calculator produces one optimistic number. This model requires three scenarios, risk-weights the claimed benefits, includes total cost of ownership, and outputs the specific metrics — NPV, IRR, payback — that Finance and investment committees use to approve or reject a case.

Can this be presented directly to the board or investment committee?

Yes. The Executive Summary tab produces a one-page investment case built around the same financial language and format a board or CFO already expects, rather than a bespoke internal template.
