This sample illustrates how item lines build the subtotal before discounts, tax, reserve, contingency, shipping, fees, and grants are applied.
Item Subtotal = Σ (Quantity × Unit Cost)
Discount Value = Item Subtotal × Discount Rate
Discounted Base = Item Subtotal − Discount Value
Tax Amount = Discounted Base × Tax Rate
Reserve Amount = Discounted Base × Reserve Rate
Contingency Amount = Discounted Base × Contingency Rate
Gross Total = Discounted Base + Tax + Shipping + Misc Fees + Reserve + Contingency
Net Total = Gross Total − Grant / Subsidy
Cost Per Student = Net Total ÷ Number of Students
Cost Per Class = Net Total ÷ Number of Classes
It totals supply line items, then applies discounts, tax, shipping, reserve, contingency, and grants. It also shows per-student and per-class costs.
Yes. Enter one class and the relevant number of students. The per-class result will then match the full plan total.
Yes. The calculator reduces the item subtotal by the discount first, then applies tax to the discounted base. That reflects many purchasing workflows.
It adds a safety margin for price changes, damaged items, or late additions. Small schools often use it to avoid underbudgeting.
Reserve covers future replacements or midterm replenishment. It is calculated from the discounted subtotal, not from shipping or grants.
No. A very large grant can reduce the net total to zero, but it should not create a negative budget.
They help compare vendors, justify requests, and set equitable supply fees. They also make year-to-year budget reviews easier.
Yes. Use the CSV button for spreadsheet analysis and the PDF button for sharing, filing, or printing budget summaries.
