Why is my AOV calculation different?

In terms of the difference between the average order value over time calculation listed in the Shopify analytics versus the average order value listed in Profit Calc.

The difference is that the Shopify average order value over time report excludes refunds and shipping revenue in the calculation.

That being said, if you have any questions about the calculation, we'd be happy to investigate on our end. Just message us on the bottom right.
