Fear & Greed Index Calculator
Aggregate volatility, volume, momentum, and survey scores into a single market-sentiment index. Use it to gauge whether the crypto market is currently in fear or greed territory before making trading decisions.
About this calculator
The Crypto Fear & Greed Index condenses multiple market signals into one number between 0 (Extreme Fear) and 100 (Extreme Greed). This simplified calculator uses an equal-weighted average: Index = (Volatility Score + Volume Score + Momentum Score + Survey Score) / 4. Each component score should be normalized to a 0–100 scale before entry. Volatility compares current price swings to historical averages; high volatility signals fear. Volume measures buying pressure relative to recent norms. Momentum captures price trend strength. Survey scores reflect direct retail sentiment polls. Scores below 25 indicate extreme fear — historically a buying signal — while scores above 75 indicate extreme greed, which has preceded corrections.
How to use
Say your data gives Volatility Score = 40, Volume Score = 65, Momentum Score = 70, Survey Score = 55. Step 1 — Sum all four scores: 40 + 65 + 70 + 55 = 230. Step 2 — Divide by 4: 230 / 4 = 57.5. Your composite index is 57.5, which falls in the 'Greed' range (51–74). This suggests the market leans bullish but has not reached euphoric levels. Adjust individual scores as new data arrives — for instance, a spike in volatility to 80 would pull the index down to (80 + 65 + 70 + 55) / 4 = 67.5, still Greed but closer to Extreme Greed.
Frequently asked questions
How is the crypto Fear and Greed Index different from the stock market VIX?
The VIX measures expected 30-day volatility of S&P 500 options and is a single, options-derived data point — higher VIX means more fear. The Crypto Fear & Greed Index is a composite of several independent signals including volatility, social media sentiment, surveys, and market momentum, each normalized and averaged. It is also crypto-specific, capturing the extreme sentiment swings typical of 24/7 digital asset markets. While VIX is an industry-standard derivative-priced measure, the Fear & Greed Index is more interpretive and should be used as one input among many.
What does a Fear and Greed score below 25 mean for crypto investors?
A score below 25 sits in the 'Extreme Fear' zone, indicating that most market participants are panicking or very pessimistic. Historically, extreme fear periods in crypto have coincided with significant price lows — the market tends to be oversold and undervalued relative to longer-term fundamentals. Many contrarian investors treat sub-25 readings as potential entry signals, though the index alone should never be the sole basis for a buy decision. Pair it with on-chain data, support levels, and macro conditions before acting.
Why should I use a Fear and Greed index when making cryptocurrency trades?
Sentiment is a powerful driver of short-term crypto price action because retail participation is high and reflexivity — prices moving sentiment moving prices — is pronounced. A high greed reading warns that the market may be overbought and vulnerable to a correction, prompting you to tighten stop-losses or take partial profits. A fear reading can highlight oversold conditions worth monitoring for accumulation. Using the index alongside technical and fundamental analysis gives a more complete picture than price charts alone, helping you avoid buying euphoric tops or panic-selling bottoms.
