  • Unit Price: $139.99
  • Accessory Cost: $15.00
  • Sales Tax Rate: 6%
  • Shipping Cost: $7.50
  • Expected Usage Lifetime: 4 years
  • Currency: USD ($)
• Calculations:
  • Subtotal (Calculators): $139.99
  • Total Before Tax: $139.99 + $15.00 + $7.50 = $162.49
  • Sales Tax Amount: $162.49 × 0.06 = $9.75
  • Total Purchase Cost: $162.49 + $9.75 = $172.24
  • Cost Per Year (TCO): $172.24 / 4 = $43.06
• Results: The student's total outlay will be $172.24, costing them approximately $43.06 per year over its expected lifetime.

Example 2: Classroom Bulk Purchase

A school district needs to purchase 25 Texas Instruments TI-84 Plus CE Graphing Calculator White units for a new classroom. They negotiate a unit price of $135.00 due to bulk, anticipate $150 total for classroom accessories (extra charging cables, storage cases), and get free shipping. The school is tax-exempt, so sales tax is 0%. They expect the calculators to last 5 years.

• Inputs:
  • Quantity: 25
  • Unit Price: $135.00
  • Accessory Cost: $150.00
  • Sales Tax Rate: 0%
  • Shipping Cost: $0.00
  • Expected Usage Lifetime: 5 years
  • Currency: USD ($)
• Calculations:
  • Subtotal (Calculators): 25 × $135.00 = $3375.00
  • Total Before Tax: $3375.00 + $150.00 + $0.00 = $3525.00
  • Sales Tax Amount: $3525.00 × 0 = $0.00
  • Total Purchase Cost: $3525.00 + $0.00 = $3525.00
  • Cost Per Year (TCO): $3525.00 / 5 = $705.00
  • Cost Per Calculator: $3525.00 / 25 = $141.00
• Results: The school's total investment for 25 calculators is $3525.00, averaging $705.00 per year for the classroom, or $141.00 per calculator including accessories. This demonstrates the impact of bulk pricing and tax exemptions on the overall budget.
