I don’t measure anything, except the kibble. I just add a glob/tablespoon of cooked protein, chicken, turkey, scrambled egg or something, and a splash/1/4 cup of water.
I would estimate 2/3rds kibble and 1/3 topper twice a day, a carrot or something for a snack here and there.
Make sure the dog is getting adequate exercise (walks for 1 hour per day), if the dog appears to be putting on weight, decrease the amount of food and increase exercise.
Calculators are not always accurate, and dogs metabolisms differ.
Weigh the dog once a week and you will find what works. Good luck
