Back-to-School Budget Calculator

June 30, 2026 • By the Investor Sam Editorial Team • Reviewed by Berly Sam Varghese, Editor
Back-to-school season is a predictable annual spike that still catches many families off guard, especially with more than one child. This calculator adds up the four big categories, supplies, clothes, shoes, and technology, on a per-child basis and multiplies across all your children. The result is a clean household total and a per-child figure so you can set a realistic budget before the flyers and shopping lists start rolling in.

Example: School supplies per child: 120 $ · Clothes per child: 200 $ · Shoes per child: 80 $ · Technology per child: 150 $ · Number of children: 2 kids

Total back-to-school cost$1,100
Cost per child$550
Supplies total (all kids)$240

Worked example

Take one child: $120 in supplies, $200 clothes, $80 shoes, and $150 in tech, for $550. With two children the household spends about $1,100, and supplies alone run $240 across both. National surveys have pegged average back-to-school spending in a similar range per student, with technology being the swing factor. Shopping tax-free weekends and reusing last year's supplies can shave a meaningful slice off the total.

Frequently asked questions

How much do families spend on back-to-school?

Annual retail surveys have put average spending in the ballpark of a few hundred dollars per student for supplies and clothing, and more when a laptop or tablet is needed. Older students and those needing electronics push the per-child figure higher, which is why the tech line matters.

When is the cheapest time to shop?

Many states hold sales-tax holidays in late summer that waive tax on clothing, supplies, and sometimes electronics up to set limits. Shopping those weekends, plus buying non-perishable supplies during clearance after the season, meaningfully lowers the total.

How can I reduce back-to-school costs?

Inventory what you already own before buying, reuse durable items like backpacks and binders, buy generic supplies, take hand-me-down clothes, and delay non-urgent tech until sales. Splitting bulk supply packs among siblings also stretches the budget.

Are school supplies tax-deductible?

For families, generally no, though teachers can deduct a limited amount of their own classroom spending. Some states offer education-related credits or deductions for certain expenses, so it is worth checking your state's rules if costs are high.
