Reward Token Dilution Calculator

Token emissions can reduce a holder's percentage ownership even when their token balance stays unchanged. This calculator starts with circulating supply, adds a constant daily emission amount over an entered number of days, and compares the holder's share before and after that expansion. It is useful for separating supply growth from ownership dilution in an explicit hypothetical scenario. The calculation runs locally in your browser. It does not forecast token prices, value rewards, fetch an emission schedule, or assume the holder receives any of the newly emitted tokens.

Measure supply growth and share dilution

New tokens equal daily emissions × days. Final circulating supply equals initial supply + new tokens. Initial ownership share equals holder tokens ÷ initial supply; final share equals unchanged holder tokens ÷ final supply. Relative dilution equals (1 − initial supply ÷ final supply) × 100. Supply growth instead divides new tokens by initial supply. These percentages use different denominators, so equal token emissions do not make them numerically identical.

Follow a constant-emission example

Suppose hypothetical circulating supply is 1,000,000 tokens, daily emissions are 10,000, and the period is 30 days. Final supply is 1,300,000. A holder with 10,000 tokens starts at 1% ownership and ends at approximately 0.7692%. The ownership share has declined by about 23.08% relative to its starting level, while circulating supply has grown 30%. Neither result implies a corresponding percentage change in market price.

Check what emissions add to circulation

The model assumes every emitted token enters circulation immediately and that no tokens are burned or otherwise removed. The holder receives no emissions, so their balance remains fixed. Initial supply must be positive and holder tokens cannot exceed it. With zero holder tokens, both shares are zero and an individual percentage decline is undefined, although the supply-based dilution factor remains calculable. Vesting, buybacks, changing emissions, and staking distributions require separate assumptions.
