What does this calculator estimate?
Supplies totaling $42.50 against a $50 budget leaves $7.50 to spare. The tool sums estimated costs and shows the surplus or shortfall.
- Surplus = budget - total estimated cost.
- The National Retail Federation tracks back-to-school spending each year.
- A written budget reduces impulse purchases.
Why a supply budget helps
Back-to-school spending creeps up — supplies, tech, and clothing add up quickly. Listing the costs against a fixed budget shows where to trim before checkout, not after.
Limitations to watch for
The tool uses the prices you enter — compare against real store prices and sales tax. School lists vary by grade; add the exact items required. Reusable items from last year can cut the list.
How to use it in practice
Enter each supply and its price, set the budget, and read the total. Trim the biggest line items first — brand-name versions cost the most. Re-check with sales tax included.
["Enter each item's cost.", 'Set the budget.', 'Read the total and remaining amount.']
