The phrase "and calculated using a" is correct and usable in written English.
It can be used when describing a method or process that involves computation or measurement based on a specific criterion or tool.
Example: "The final score was determined and calculated using a complex algorithm that takes multiple factors into account."
Alternatives: "and computed with a" or "and assessed using a".
