Bid Ask Spread

Bid-offer or bid-ask spread is calculated as:

Spread = Ask - Bid

The spread is the difference between the quoted sale price (bid) and the quoted purchase price (ask) of a security, stock, or currency exchange.

Bid Ask Margin

Bid-ask margin is the spread percentage, or the difference between ask and bid prices divided by the ask price. Percentage spread is calculated as:

Margin % = \( \dfrac{(Ask-Bid)}{Ask} \times 100 \)

The bid ask margin is the percentage change, bid price relative to ask price.
