What is a {primary_keyword} Calculator?
A {primary_keyword} calculator is not a tool for performing mathematical graphing functions, but rather a financial utility designed to determine the precise total cost of purchasing a Texas Instruments TI-84 graphing calculator from a Costco warehouse or Costco.com. Students, parents, and educators use this calculator to budget accurately by including often-overlooked expenses like sales tax. Furthermore, it quantifies the financial benefit of a Costco Executive Membership by calculating the 2% reward, helping users see the net cost and make informed purchasing decisions. The tool is specifically built to address the unique pricing factors associated with buying electronics at a members-only warehouse club.
{primary_keyword} Formula and Explanation
The calculation is a straightforward process that aggregates the base price and applicable taxes, then subtracts any member-specific rewards. The formula is as follows:
Total Cost = (Base Price * (1 + (Sales Tax Rate / 100))) – Executive Reward
The Executive Reward is only applied if that membership level is selected and is calculated as 2% of the pre-tax price.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Base Price | The shelf price of the TI-84 calculator at Costco. | USD ($) | $90 – $150 |
| Sales Tax Rate | The combined state and local sales tax percentage. | Percentage (%) | 0% – 11% |
| Executive Reward | A 2% rebate on the purchase for Executive members. | USD ($) | $2 – $3 |
Practical Examples
Understanding the numbers in a real-world context can clarify the calculator’s utility.
Example 1: Gold Star Member in California
- Inputs: Base Price = $119.99, Sales Tax = 7.25%, Membership = Gold Star
- Calculation:
- Tax Paid: $119.99 * 0.0725 = $8.70
- Total Cost: $119.99 + $8.70 = $128.69
- Executive Reward: $0
- Result: The final cost for the Gold Star member is $128.69.
Example 2: Executive Member in Texas
- Inputs: Base Price = $119.99, Sales Tax = 8.25%, Membership = Executive
- Calculation:
- Tax Paid: $119.99 * 0.0825 = $9.90
- Total Cost: $119.99 + $9.90 = $129.89
- Executive Reward: $119.99 * 0.02 = $2.40
- Net Cost: $129.89 – $2.40 = $127.49
- Result: The final cost is $129.89, but the effective net cost after the 2% reward is $127.49.
