Calculator
Enter mention counts from surveys, reviews, social listening, or support tickets. Use weights to reflect channel importance.
Example data table
These examples use weights P=1.0, N=1.2, Neu=0.0 and confidence 0.85.
| Scenario | Positive | Negative | Neutral | Score | Index | Label |
|---|---|---|---|---|---|---|
| New product launch | 120 | 40 | 60 | 42.86 | 71.43 | Positive |

Formula used
Weighted totals
- Weighted Positive = Positive × wp
- Weighted Negative = Negative × wn
- Weighted Neutral = Neutral × wu
- Weighted Total = WP + WN + WU
Sentiment score
Sentiment Score = ((WP − WN) / Weighted Total) × 100
Sentiment index (0–100)
Sentiment Index = (Sentiment Score + 100) / 2
Confidence-adjusted index
Adjusted Index = Sentiment Index × Confidence (0–1)

FAQs
1) What is a sentiment score in marketing?
It summarizes audience mood by comparing positive and negative feedback. Higher scores suggest healthier perception and stronger campaign resonance.
2) Why use weights?
Weights let you treat some channels as more important. For example, a complaint from a premium customer might matter more than a casual comment.
3) Should neutral mentions affect the score?
If you want a pure “net sentiment” view, set neutral weight to zero. If neutrals dilute strong opinions, use a small neutral weight.
4) What does confidence factor do?
It scales the index to reflect sample reliability. Use lower confidence for small datasets, limited channels, or early launches with volatile feedback.
5) How do I interpret a negative score?
Negative values mean weighted negatives outweigh weighted positives. Investigate topics driving complaints, then track improvements after fixes or messaging updates.
6) Can I compare two campaigns?
Yes. Use the same weights and confidence rules for both. Compare sentiment score and index over the same time window to avoid seasonal bias.
7) Is this the same as text sentiment analysis?
No. This tool uses your categorized counts, not automatic language processing. It’s ideal when you already label feedback or use a listening tool’s labels.
