Liquidity Pool Share Calculator
When you provide liquidity to a decentralised exchange pool, you receive LP tokens representing your fractional claim on the pooled assets. This calculator works out your pool share from your deposit and the existing pool value, and shows the underlying amounts of each token your position represents. All values are the figures you supply; nothing is fetched from a chain or invented.
Pool share formula
Total pool value = existing pool value + your deposit
Pool share = your deposit / total pool value
Your token A = pool share * reserve of token A
Your token B = pool share * reserve of token B
Enter token reserves as the totals after your deposit. Pool share is shown as a percentage; token amounts are in token units.
Worked example
You deposit 10,000 into a pool already holding 1,000,000, so total value is 1,010,000. Your pool share is 10,000 / 1,010,000 = 0.99%. If the pool's reserves after your deposit are 500,000 token A and 2,000,000 token B, your claim is 0.0099 * 500,000 = 4,950.50 token A and 0.0099 * 2,000,000 = 19,801.98 token B.
Liquidity pool share: frequently asked questions
How is a liquidity pool share calculated?
Your pool share is your contribution divided by the total pool value after your deposit, expressed as a percentage. If a pool holds 1,000,000 in value and you add 10,000, the new total is 1,010,000 and your share is 10,000 / 1,010,000 = 0.99%. Your LP tokens represent that claim on the pool.
How do I find the token amounts I own?
Multiply your pool share by each token reserve in the pool. In a two-token pool with reserves of token A and token B, your claim is share times reserve A of token A plus share times reserve B of token B. As trades change the reserves, your token amounts change but your share (LP token fraction) stays constant unless others add or remove liquidity.
Does a larger share mean more fees?
Yes. Trading fees in an automated market maker pool accrue to liquidity providers in proportion to their pool share. A 1% share earns roughly 1% of the fees the pool collects while you remain in it, before considering impermanent loss.
