ESG Score Calculator
ESG composite score.
Calculate a composite ESG score from Environmental, Social, and Governance dimensions, weighted by the priorities you set.
What this tool does
A composite ESG score is a weighted average of Environmental, Social, and Governance components on a 0–100 scale. Enter scores for each of the three dimensions, then assign the percentage weight you want each to carry in your overall calculation. The calculator returns a single composite figure that blends these three components according to your weighting preference. This output represents how an asset or portfolio ranks across ESG criteria based on the relative importance you place on each pillar. The weights you assign have the most influence on the result—changing them will shift the composite score meaningfully. A typical use case is screening potential investments by comparing their ESG profiles. Note that this calculator produces an illustrative composite score only; it does not account for data quality, methodology differences across ESG providers, or how external factors might affect component scores over time.
Quick answer: with the default values, the result is 71.8 / 100 (ESG Composite Score). Adjust the values below for your own figures.

ESG composite score calculator combines Environmental, Social, and Governance dimensions into single rating. E:75 + S:60 + G:80 with equal weights = 71.7 composite. ESG ratings used by investors to screen holdings, by companies to track progress, by employees evaluating employer impact. MSCI, Sustainalytics, Refinitiv all publish ESG ratings.
Example: company scoring E:75 (strong climate practices), S:60 (decent labour relations), G:80 (excellent board composition). Equal-weighted composite: (75+60+80)/3 = 71.7. B rating (above average). Different providers weight differently - MSCI weights by industry materiality (oil company E weighted higher than software company E). Composite score useful for cross-company comparison.
ESG investing growth: sustainable and ESG-aligned assets now run into the tens of trillions globally (industry estimates vary). Active ESG funds, ESG ETFs, exclusion-based funds (no tobacco/weapons). Performance debate: ESG-aligned funds have historically been reported as matching or slightly outperforming the broad market, with some research finding reduced tail risk and other research finding the opposite. Critical issues: greenwashing (companies claiming ESG without substance), inconsistent ratings (same company different scores from different providers), regulation tightening (disclosure frameworks such as TCFD and regional climate-disclosure rules).
Quick example
With environmental score of 75 and social score of 60 (plus governance score of 80 and environmental weight of 33%), the result is 71.8 / 100.
Which inputs matter most
You enter Environmental Score (0-100), Social Score (0-100), Governance Score (0-100), Environmental Weight %, Social Weight %, and Governance Weight %.
What's happening under the hood
Weighted average of E, S, G scores. Weights must sum to 100%.
Where this fits in planning
This is a "what-if" tool, not a forecast. It helps to test ideas: what happens if you shift weight toward governance, or if one component score moves up or down. The value is in the scenarios you run, not the single answer you get from the defaults.
E:75 × 33% + S:60 × 33% + G:80 × 34% = 71.8 / 100.
Inputs
| Environmental Component | 75 × 33.00% |
|---|---|
| Social Component | 60 × 33.00% |
| Governance Component | 80 × 34.00% |
| ESG Rating | B (above average) |
This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.
Sources & Methodology
Methodology
This calculator computes a composite ESG score by taking a weighted average of three component scores: environmental, social, and governance. Each component score is multiplied by its assigned weight (expressed as a percentage), the products are summed, and the total is divided by 100 to normalize the result. The model assumes that the three weights sum to 100 percent and that each input score falls between 0 and 100. The calculator does not adjust scores for data quality, market conditions, time periods, or relative materiality across sectors. Results reflect only the arithmetic combination of inputs as specified and do not account for correlation between ESG dimensions or qualitative factors that may influence investment outcomes.
