About this calculator
Stakeholder management requires more than a 2×2 power/interest grid. This calculator produces a composite influence score using the formula: Score = (powerLevel × interestLevel × networkSize) × (1 + attitude × 0.2). Power and interest are rated 1–5 and network influence 1.0–2.0, so the score runs from 0.6 to 70. Multiplying them together rather than adding them reflects the compounding nature of influence — a stakeholder who is powerful, highly interested, AND well-connected is exponentially more impactful than one who scores high on only one dimension. The attitude modifier adjusts the score upward for supportive stakeholders and downward for opponents, because a resistant stakeholder with high influence demands a different (and more intensive) engagement strategy than a passive one. Attitude is usually scored from −2 (strongly opposed) to +2 (strongly supportive).
How to use
A stakeholder has High Power (4), High Interest (4), a Medium Network (1.5) and a Positive attitude (+1). Step 1 — base score: 4 × 4 × 1.5 = 24. Step 2 — attitude modifier: 1 + (1 × 0.2) = 1.2. Step 3 — final score: 24 × 1.2 = 28.8. Now score a second stakeholder: Very High Power (5), Medium Interest (3), Small Network (1.2), Strongly Negative (−2). Base = 18, modifier = 1 + (−2 × 0.2) = 0.6, score = 18 × 0.6 = 10.8. Despite higher power, the second stakeholder scores lower in this model because of the opposition and lower interest — but note that a powerful opponent still needs close management.
Frequently asked questions
How do I rate a stakeholder's network influence?
Network influence captures how many other stakeholders a person can sway through informal channels. Use Limited (1.0) or Small (1.2) for stakeholders with a local network and little cross-department reach, Medium (1.5) for managers or technical leads respected within their function, and Large (1.8) or Very Large (2.0) for executives, board members, or external opinion leaders whose endorsement or opposition can shift many other stakeholders. Interview your core team and review org charts to calibrate ratings before the engagement planning session.
What is the difference between a stakeholder's power and their interest in a project?
Power refers to a stakeholder's formal or informal authority to affect project decisions, resource allocation, or approvals — regardless of whether they choose to exercise it. Interest measures how much they care about the project's outcome, how closely they monitor progress, and how likely they are to get involved. A senior executive may have very high power but low interest, meaning they can block you if provoked but are unlikely to engage proactively. Conversely, an end-user group may have low formal power but very high interest, making them active vocal advocates or critics who influence other stakeholders indirectly.
When should I update stakeholder influence scores during a project lifecycle?
Stakeholder scores should be recalculated at every major project gate or phase transition, and immediately after any significant organizational change such as a leadership reshuffle, merger, or budget cut. Attitudes in particular change frequently — a previously neutral stakeholder can become a champion after a successful demo, or turn into an opponent after a missed commitment. Treating influence scores as fixed from project initiation is one of the most common stakeholder management failures. Many project managers build a quarterly stakeholder review into their governance calendar to keep the engagement plan current.
