What is NFT rarity, and how to calculate it?

Non-Fungible Tokens (NFTs) have exploded in popularity in recent years, with millions of dollars being spent on digital art, collectibles, and other unique items. One of the key factors that influences the value of an NFT is its rarity. In this article, we will explore what NFT rarity is, and how to calculate it.

What is NFT Rarity?
NFT rarity refers to how rare and unique an NFT is. Just like with physical collectibles, the rarer an NFT is, the more valuable it tends to be. Rarity can be influenced by a number of factors, including the number of NFTs in existence, the characteristics of the NFT, and the demand for the NFT.

How to Calculate NFT Rarity
There are several factors to consider when calculating NFT rarity. These include:

a. Edition size

One of the most important factors to consider when calculating NFT rarity is the edition size. The edition size refers to the number of copies of the NFT that have been produced. Generally, the smaller the edition size, the more rare and valuable the NFT is.

b. Scarcity of traits

Another important factor to consider when calculating NFT rarity is the scarcity of traits. Traits refer to the characteristics of the NFT, such as the color, shape, and design. If an NFT has rare or unique traits, it is generally more valuable than NFTs with more common traits.

c. Historical sale data

Historical sale data can also be used to calculate NFT rarity. By looking at the sale history of similar NFTs, you can get an idea of how rare and valuable the NFT is likely to be. This can help you determine a fair price for the NFT if you are buying or selling it.

d. Demand

Finally, demand is a key factor to consider when calculating NFT rarity. The more people that are interested in an NFT, the more valuable it tends to be. This can be influenced by a number of factors, including the popularity of the artist or creator, the uniqueness of the NFT, and the current trends in the NFT market.

Tools for Calculating NFT Rarity
There are several tools available that can help you calculate NFT rarity. These include:

a. Rarity.tools

Rarity.tools is a popular tool for calculating NFT rarity. It uses a combination of edition size, trait scarcity, and historical sale data to calculate a rarity score for each NFT. This can help you determine how rare and valuable the NFT is likely to be.

b. NonFungible.com

NonFungible.com is another tool that can help you calculate NFT rarity. It provides a range of data on NFTs, including edition size, historical sale data, and rarity scores. This can help you compare different NFTs and determine which ones are the most rare and valuable.

c. OpenSea

OpenSea is a popular marketplace for buying and selling NFTs. It provides a range of data on NFTs, including edition size, traits, and historical sale data. This can help you determine the rarity and value of the NFTs you are interested in buying or selling.


In conclusion, NFT rarity is a key factor that influences the value of NFTs. Rarity can be influenced by a number of factors, including edition size, trait scarcity, historical sale data, and demand. There are several tools available that can help you calculate NFT rarity, including Rarity.tools, NonFungible.com, and OpenSea. By understanding NFT rarity and how to calculate it, you can make informed decisions when buying or selling NFTs and potentially maximize their value. However, it’s important to keep in mind that rarity is just one factor that influences the value of NFTs, and that other factors such as the quality of the artwork, the reputation of the creator, and the overall market conditions can also play a significant role. Additionally, the NFT market is still relatively new and can be volatile, so it’s important to approach NFT investments with caution and do your own research before making any decisions. Overall, NFT rarity can be a useful tool for understanding the value of NFTs, but it’s just one piece of the puzzle in a rapidly evolving market.
