 ## Transaction Fees
 
-Every transaction must destroy a small amount of XRP as a cost to send the transaction. This is also called a *transaction fee*. The transaction cost is designed to increase along with the load on the XRP Ledger, making it very expensive to deliberately or inadvertently overload the peer-to-peer network that powers the XRP Ledger.
+Every transaction must destroy a small amount of XRP as a cost to apply the transaction to the ledger. This is also called a *transaction fee*. The transaction cost is designed to increase along with the load on the XRP Ledger, making it very expensive to deliberately or inadvertently overload the peer-to-peer network that powers the XRP Ledger.
 
 You can choose the size of the fee you want to pay or let a default be used. You can get an estimate of the fee required to be included in the next ledger closing with the [getFee](#getfee) method.
 
+For a multi-signed transaction, ripple-lib automatically multiplies the `fee` by (1 + Number of Signatures Provided). For example, if you set `instructions.fee = '0.000020'` and `instructions.signersCount = 2`, the prepared transaction's `Fee` will be 20 drops × (1 + 2 Signatures) = 60 drops. See [Transaction Cost](https://developers.ripple.com/transaction-cost.html).

 ## Transaction Instructions
 
 Transaction instructions indicate how to execute a transaction, complementary with the [transaction specification](#transaction-specifications).

@@ -43,10 +43,12 @@ Executing a transaction with `RippleAPI` requires the following four steps:
 
 ## Transaction Fees
 
-Every transaction must destroy a small amount of XRP as a cost to send the transaction. This is also called a *transaction fee*. The transaction cost is designed to increase along with the load on the XRP Ledger, making it very expensive to deliberately or inadvertently overload the peer-to-peer network that powers the XRP Ledger.
+Every transaction must destroy a small amount of XRP as a cost to apply the transaction to the ledger. This is also called a *transaction fee*. The transaction cost is designed to increase along with the load on the XRP Ledger, making it very expensive to deliberately or inadvertently overload the peer-to-peer network that powers the XRP Ledger.
 
 You can choose the size of the fee you want to pay or let a default be used. You can get an estimate of the fee required to be included in the next ledger closing with the [getFee](#getfee) method.
 
+For a multi-signed transaction, ripple-lib automatically multiplies the `fee` by (1 + Number of Signatures Provided). For example, if you set `instructions.fee = '0.000020'` and `instructions.signersCount = 2`, the prepared transaction's `Fee` will be 20 drops × (1 + 2 Signatures) = 60 drops. See [Transaction Cost](https://developers.ripple.com/transaction-cost.html).
+
 ## Transaction Instructions
 
 Transaction instructions indicate how to execute a transaction, complementary with the [transaction specification](#transaction-specifications).
