Every August, stores burst with notebooks, new sneakers, and reminders that back-to-school prep isn’t just about picking out a few fresh pencils. For most families, stocking up on supplies, buying clothes, and enrolling kids in activities is a huge expense. On average, parents spend around $586 per child just on school needs—and that doesn’t even include the $582 many forks over for extracurriculars. Add it up for two or three kids and you’re not buying a new backpack—you’re buying a new bill.
