How to calculate the Pump.fun slippage %?

To calculate slippage between the two transactions, we need to gather and analyze the following details for each transaction:

• Token Amount Purchased: The number of tokens each wallet bought.

• Price Paid Per Token: The price at which the tokens were purchased.

• Price Difference: How much did the price change between the two transactions.

Steps to Calculate Slippage:

1. For each transaction gather Transaction Data:

   • Amount of tokens bought.

   • Total amount paid (in SOL).

2. Calculate Price Per Token:

   • For each transaction, calculate the token price.

1. Find Price Difference:

   • Determine the difference in price per token between the two transactions.

The result you get is the slippage percentage. (price difference between the two transactions.)

Example:

Wallet A bought 25,912,154 Token GOLDIE for 0.753480602 SOL.

Step 1: Calculate Price Per Token for Each Transaction:

Step 2: Calculate Slippage:

Result

The slippage between the two transactions is approximately 5.09%.

This means that between the first and second transactions the price per token increased by 5.09% due to the market impact of the first purchase.
