How would you count these homemade tortilla chips

OK so after roasting a chicken I used the drippings to bake some corn tortillas for chips. There was 90 G's of chicken drippings with six tortillas submerged and flopped around til coated. After I put them on the baking sheet I poured out 15 G's of leftover grease, then dabbed off another 15 G's with a paper towel. After they came out of the oven I discarded an additional 15 G's of excess grease.

So, 50 calorie per tortilla and then like 120 calorie per 15 G tablespoon of chicken drippings for a total of 760 calorie? Does that seem correct? Thanks all
