The average American eats an average of 4.2 commercially prepared meals per week. In other words, as a nation, we eat out between four and five times a week, on average.t an average cost of $12.75 per meal, youâd save yourself $8.75 for each of those meals. In other words, the average American would save $36.75 per person per week by moving all of their meals from restaurants to home-prepared meals.
The average household consists of 2.5 people, who spend $6,602 on food per year. Letâs assume that a person eats three meals a day, 365 days a year. That adds up to 2,737.5 meals a year for that average family. In other words, the average American spends $2.41 per average meal. Now, letâs say that average American family can shave just $0.10 off of their average meal. You can do that by eating out one fewer time every other week or eating a super cheap supper one night a week â it doesnât take much to cut that average cost.
