Answer by Tradergordo. Confidence votes 788. There are about 200 calories per serving, serving size is 2 tbsp. In an 18oz jar there are about 16 servings, so that's 3,200 calories in an 18oz jar of peanut butter.
One serving of peanut butter is roughly 190 calories. One serving of crackers (usually about 5 or 6 crackers) can be anywhere from around 120 to 240 calories. So that's about â¦300 to 400 calories, varrying based on brand and serving sizes and ingredients.
