Enter estimated costs for each school supply category to calculate your total back-to-school budget. The categories mirror the National Retail Federation's annual Back-to-School survey groupings. Adjust each field to zero if a category does not apply.
Budget formula
Total per student = Sum of all supply categories
Total for all students = Total per student x Number of students
Monthly equivalent = Total per student / 10 months
Cost-saving strategies
- State sales tax holidays: many states exempt school supplies and clothing from sales tax for 1-3 days in late July or early August. Check your state tax authority's website for dates and qualifying items.
- Textbook rental: renting versus buying textbooks can save 40-80% per book. College campus bookstores and online platforms offer rental programs.
- Free classroom supplies: programs like DonorsChoose.org provide classroom supplies for teachers. For students, many school districts have supply assistance programs.
- Technology: many colleges negotiate student discounts on software (Adobe, Microsoft 365) and hardware. Check your institution's IT page before purchasing at retail price.
Frequently asked questions
How much does the average family spend on school supplies?
According to the National Retail Federation's annual Back-to-School survey, families with K-12 students spent an average of approximately $890 per student on school supplies, clothing, electronics, and related items in 2023. College students averaged over $1,050 on supplies and electronics for the academic year.
What school supply costs are tax deductible?
K-12 educators (teachers, instructors, counselors, principals, and aides in K-12 for at least 900 hours per school year) can deduct up to $300 of out-of-pocket classroom supplies as an above-the-line deduction under IRC Section 62(a)(2)(D). For students and parents, general school supply costs are not federally deductible, but some states offer a sales tax holiday on school supplies during the back-to-school period.
What are the biggest school supply cost drivers?
Technology items (laptops, tablets, calculators) and clothing typically account for the largest share of back-to-school spending. A laptop alone can range from $300 to $1,500. Scientific or graphing calculators cost $80-$150. Spreading technology purchases over multiple years reduces annual cost.
Can I deduct school supplies as a college student?
College students may include required course materials (textbooks, supplies) as qualified education expenses for the American Opportunity Tax Credit or Lifetime Learning Credit. However, general school supplies that are not required course materials do not qualify for these credits.
How can I reduce school supply costs?
Shop during state sales tax holidays, buy used textbooks or rent them, use school library resources, buy generic-brand supplies, buy in bulk with other families, and take advantage of school district supply programs or free-supplies programs offered by nonprofits and local businesses.
