Formula Used

The calculator uses the following formula to compute the total repair cost:

Total Repair Cost = (Labor Hours × Hourly Rate) + Parts Cost + (Parts Cost × Tax Rate)

Where:

Labor Hours = Number of hours worked
Hourly Rate = Cost per hour of labor
Parts Cost = Total cost of replacement parts
Tax Rate = Applicable sales tax percentage

Note: The tax is applied only to the parts cost, not the labor cost, as labor costs are typically not taxable in most jurisdictions.

Worked Example

Let's walk through an example to see how the calculator works in practice.

Scenario

A mechanic performs a 3-hour oil change and replaces a $120 brake pad. The labor rate is $75/hour, and the sales tax rate is 8%.

Calculation Steps

Labor Cost = 3 hours × $75/hour = $225
Parts Cost = $120
Tax on Parts = $120 × 8% = $9.60
Total Repair Cost = $225 + $120 + $9.60 = $354.60

Result

The total repair cost for this example is $354.60. Using the calculator, you can quickly generate similar estimates for different repair jobs.

Description	Amount
Labor Cost	$225.00
Parts Cost	$120.00
