How can I calculate actual yearly shipping costs on Shopify?

HI There, I set my shopify shipping charges up to where I make a little money on shipping charges to help pay for my shipping employees. Is there a way to determine how much I spent in ACTUAL shipping. I found my total yearly shipping charges (which includes the profit), but How do I find the Actual shipping charges paid out to usps for the year (minus the little profit)?

Go to Finances - Billing. All the way at the bottom click on View Statement of Charges. The data on that page is only available for the last 90 days but it gives you a breakdown of your fees.

The only other option that may work is to view your Billing History and export your bills selecting the date range that you need. Actually, this may work the best because once you download the excel sheet you can filter by description and get a total.
