Which social impact measurement method should you choose?
Social impact measurement has become a strategic priority for nonprofits, foundations, and funders.
Far from being just a reporting requirement, it is now a key tool to:
understand the real effects of your actions,
improve decision-making,
strengthen accountability and transparency.
But one question remains central: which method should you choose to evaluate your social impact?
From self-assessment to consultancy-led studies, there are several approaches—each with different levels of rigor, cost, and complexity.
👉 The right choice depends primarily on one factor: your objective.
Define your objective before choosing an impact evaluation method
Not all impact measurement approaches serve the same purpose.
In practice, social impact assessment can target four levels:
1. Monitoring (output & outcome tracking)
Track key indicators such as:
number of beneficiaries reached,
access to services,
skills developed.
👉 Goal: measure what is happening
2. Understanding (analysis of outcomes)
Go further by identifying:
why certain results occur,
which factors influence success or failure.
👉 Goal: understand what works (and why)
3. Demonstrating (causality and attribution)
Use rigorous methods to prove that:
your actions directly contributed to observed changes,
results are not due to external factors.
👉 Goal: prove your impact
4. Monetising (social value estimation)
Assign a financial value to outcomes (e.g. SROI).
👉 Goal: quantify impact in monetary terms
💡 Each level requires different resources, expertise, and methodologies. A simple monitoring system does not require the same investment as a scientific impact study.
3 methods to measure social impact
In practice, most organisations rely on one of the following three approaches.
1. Conducting your own social impact assessment (in-house)
Some organisations choose to build their own impact measurement framework internally:
defining indicators,
designing surveys,
analysing results.
Key figures
Budget: up to €4,000
Time required: ~40 working days
Duration: 10–12 months
Pros
Full control over the process
Strong internal ownership
Challenges
Requires time and methodological skills
Often difficult to prioritise internally
Risk of inconsistent or non-actionable results
In many organisations, impact measurement is not a dedicated role. Teams often juggle multiple responsibilities, which can slow down or weaken the process.
Useful resources to get started
Resource organisations: Avise, La Fonda, VALOR’ESS, Social Value International
Online courses:
ESSEC MOOC on social impact evaluation
Admical / ESSEC / Kimso training
Acumen Lean Data approach
Consultancy-led training programmes
👉 This approach is best suited for organisations starting their journey and building internal capacity.
2. Using a guided approach (tools + expert support)
A second option is to combine autonomy with external support. The organisation leads the process, but benefits from:
a structured methodology,
pre-built indicator frameworks,
expert guidance when needed.
Key figures
Budget: €2,500 to €7,000
Time required: 5–20 working days
Duration: 6–10 months
What specialised tools enable
Access to indicator databases by sector (education, health, employment…)
Robust questionnaire design based on social science methods
Statistically reliable data collection
Data visualisation dashboards
📊 Data visualisation is critical: According to Koreis (french consulting firm specalized in impact assessment), 64% of organisations advanced in impact management use visualisation tools.
Pros
Good balance between rigor and feasibility
Faster deployment
Results easier to use for decision-making
👉 This approach is ideal for organisations that want to:
structure a shared evaluation framework,
improve continuously based on feedback,
strengthen reporting to funders.
3. Outsourcing to a social impact consultancy
Some organisations choose to delegate their impact evaluation to specialised firms.
This is common for:
large-scale programmes,
funder requirements,
need for strong scientific evidence.
Key figures
Budget: €20,000 to €300,000
Internal time required: 3–10 days
Duration: 3–6 months
Pros
High level of methodological rigor
Strong credibility (external validation)
Limitations
Often one-off studies
Limited use for ongoing operational management
Less internal ownership
👉 This approach is best suited for demonstrating impact, not for continuous steering.
Why social impact measurement is more than reporting
Too often, impact measurement is seen as a requirement imposed by funders. In reality, it is a powerful management tool. When used effectively, it helps organisations to:
better understand their impact,
adapt activities based on beneficiary feedback,
strengthen credibility,
build trust with partners.
How to choose the right impact measurement approach
The best method depends on how you plan to use your results:
👉 Monitor performance: lightweight internal or guided approach
👉 Improve your programmes: guided approach with tools
👉 Prove impact: consultancy-led study
👉 Scale impact management: structured tools and systems
Between simple monitoring and complex evaluation, hybrid approaches are emerging—combining rigor with usability. This is precisely the goal of platforms like Impact Track, which enable organisations to:
structure their methodology,
save time,
make impact data actionable.
