Packed lunch

A lunch made at home and carried to school or work, which USDA says needs at least two cold sources when it holds perishable food.

What It Means

A packed lunch is a meal made at home and carried in a lunch bag or box to school or work, instead of buying lunch there. Two questions come with it: what it costs next to the school's lunch price, and how to keep perishable food such as meat, eggs and dairy cold until lunchtime. USDA's answer to the second is an insulated bag with at least two cold sources.

Try It: Compare a Packed Lunch With School Lunch

Enter what each part of a packed lunch costs you, the school's lunch price and the number of school days. All starting numbers are examples.

Packed lunch, per day$2.75
Packed, per year$495
School lunch, per year$585
Difference over the year$90

Packing costs less at these prices.

If it holds perishable food, pack at least two cold sources, per USDA.

How Parents Say It

  • "Are you buying or bringing today?"
  • "Don't forget the ice pack, there's yogurt in there."
  • "Packing lunch saves us a bit, but it's another job every night."

The Breakdown

Worked example (example prices; your store and your district's menu will differ)

ItemCost per day
Sandwich$1.25
Fruit or vegetables$0.50
Snack$0.60
Drink$0.40
Packed lunch$2.75
School lunch (example price)$3.25

Over a 180-day school year, used here as an example, the packed lunch comes to $495 and school lunch to $585, a difference of $90 for one child.

What the result means. A positive gap is what packing saves for one child over the year at these prices. Change one input at a time to see which item moves it most, and remember the first year also carries the cost of an insulated bag and cold packs.

What moves the number

  • The school's lunch price, which your district sets
  • How many days you actually pack, since some families mix the two
  • Whether your child qualifies for free or reduced-price meals, which Buhata's free and reduced lunchFree and reduced lunchFederal school meals at no cost or a reduced price for children whose household income is at or under 130 or 185 percent of the poverty guidelines, or who qualify another way.

Good to Know

USDA's food safety rule for lunches is time and temperature. Perishable food shouldn't sit at room temperature for more than 2 hours, or 1 hour when it's above 90 degrees F, because bacteria multiply quickly between 40 and 140 degrees F. Pack it in an insulated, soft-sided bag or box with at least two cold sources: two frozen gel packs, each at least 5 by 3 inches, or one gel pack with a frozen juice box or frozen bottle of water. Put them on top of and below the perishable food.

FAQ

How do I keep a packed lunch cold without a fridge?

Use an insulated, soft-sided lunch bag with at least two cold sources, USDA says, such as two frozen gel packs or a gel pack plus a frozen juice box or water bottle, placed above and below the perishable food.

How long can a packed lunch sit out?

No more than 2 hours for perishable food, or 1 hour if it's above 90 degrees F, according to USDA.

Is packing lunch cheaper than school lunch?

It depends on your district's price and what goes in the bag. Add up a typical packed lunch, multiply by your school days, and compare it with the school price times the same days.
