Back to School Cost Calculator
Estimate back-to-school expenses for supplies, clothing, and tech by grade level and number of children.
Build a realistic annual school shopping budget.
Back-to-school supply budget planning helps families manage one of the largest recurring educational expenses of the year. The National Retail Federation estimates the average American family spends $890 per K-12 student on back-to-school shopping (2024), though costs vary widely by grade level, school requirements, and shopping strategy.
Total budget formula: Total Budget = Supplies Cost + Clothing Cost + Technology Cost + Activity/Fee Cost
Average supply costs by grade level (U.S. 2024):
| Grade Level | Supplies | Clothing | Technology | Total Est. |
|---|---|---|---|---|
| Kindergarten–2nd grade | $50–$120 | $100–$200 | $0–$50 | $150–$370 |
| 3rd–5th grade | $80–$150 | $150–$300 | $0–$100 | $230–$550 |
| Middle school (6–8) | $100–$200 | $200–$400 | $100–$300 | $400–$900 |
| High school (9–12) | $100–$250 | $200–$500 | $100–$500 | $400–$1,250 |
