This year, the price of lunch at my kids’ school is $2.75 per meal. That’s the same price as last year. As a result, I’m sure many busy parents struggling to make ends meet probably believe that’s a bargain for lunch — especially considering that grocery prices in 2014 have been rising sharply. Unfortunately, those parents would be wrong; at $2.75 per meal, a family with two kids will spend $990 on school lunches over the course of a 180-day school year.
Believe it or not, despite those higher grocery bills, you’re still better off bypassing that school cafeteria fare in favor of making your kids a brown bag lunch. It’s true: For most people, brown-bagging a sandwich, piece of fruit and carrot sticks or a serving of chips is less expensive than buying lunch.
Of course, as I’ve pointed out before, not all sammies are created equal: Just ask the Expensive Sandwich King, celebrity chef Martin Blunos, whose $184 cheese sarnie caused quite a stir a few years ago. The good news is, the results of my sixth annual brown bag sandwich price survey show that most folks will spend far less than that in 2014 — even for the most expensive sandwich on the list.
How the survey was conducted
As I have every year since conducting my first sandwich survey in 2009, I took a trip down to my local grocery store and recorded the per-serving costs of various ingredients for 10 of the most common brown bag sandwiches: peanut butter and jelly; bologna; tuna; ham and Swiss; roast beef and cheddar; egg salad; salami; American cheese; turkey; and bacon, lettuce and tomato.
As in my past sandwich surveys, for consistency in determining prices of the individual sandwich ingredients, I only selected items with the cheapest per unit costs, regardless of brand. To keep it simple, I also assumed all sandwiches would be made with wheat bread.
Here are the results of my price survey, conducted Aug. 9, 2014. The first graphic shows the sandwich serving sizes and per-serving costs for each ingredient. It also includes the percentage increase or decrease in the per-serving price of each item from last year’s survey:
With that data in hand, and using my handy spreadsheet, it was no effort at all to determine the most economical sandwiches.
Here are the official Len Penzo dot Com rankings of the 10 most common brown bag sandwiches in 2014. Rankings are based upon total ingredient unit costs, from least to most expensive. As you can see, bologna and good ol’ PB&J share this year’s award for the most economical sandwich; each costs just 44 cents.
The next chart shows a year-by-year comparison for each sandwich since my first survey in 2009. As you can see, prices continue to climb. In 2009, the average price of the 10 sandwiches was 82 cents. Today, it’s $1.19 — that’s a 45 percent increase since 2009, and an all-time high for this survey.
I realize that some people don’t use any spreads at all, some folks enjoy two or three slices of bologna, and BLTs aren’t the only sandwiches that can have lettuce and tomato. The good news is, it’s all relative. If you make your sandwiches differently, use my shopping survey numbers in the top figure to adjust your sandwich costs accordingly.
