Calculate token dilution
When a project mints new tokens, through emissions, unlocks or a raise, the ownership share of existing holders falls, an effect called dilution. This calculator measures it from the current supply and the number of new tokens issued. Dilution is the new tokens as a percentage of the resulting total supply, so adding twenty million to a hundred-million supply dilutes holders by about 16.7 percent. If you enter your holdings, it shows how your ownership share shrinks from before to after.
Even if the token count you hold is unchanged, your proportional claim on the project shrinks as supply grows.
Why dilution matters
Dilution is one of the most important and overlooked risks in token economics. A token with high ongoing emissions or large upcoming unlocks can see its price pressured as supply expands, even if demand holds steady, because each token represents a smaller slice of the whole. Understanding the dilution schedule helps you assess whether a token valuation accounts for future supply growth.
Compare dilution against the project growth to judge whether new issuance is justified. All calculation happens locally in your browser.

Frequently Asked Questions
What is token dilution?
It is the reduction in existing holders ownership share when new tokens are issued, since each token becomes a smaller slice of a larger supply.
How is dilution calculated?
It is the number of new tokens as a percentage of the resulting total supply after the new tokens are added.
Does dilution reduce my token count?
No. You keep the same number of tokens, but they represent a smaller proportion of the total supply, reducing your ownership share.
Why is dilution a risk?
High emissions or large unlocks expand supply, which can pressure the price and dilute value even if demand stays constant.
