Worked Examples

Let's look at two examples to illustrate how the calculator works:

Example 1: Leaving a Current Vehicle

Suppose you currently own a 2015 Toyota Camry with a current value of $15,000. You drive it 12,000 miles per year. The standard mileage rate for 2018 is 57.5 cents per mile.

Your estimated tax savings from leaving this vehicle would be calculated as follows:

Tax Savings = (Annual Mileage × Standard Mileage Rate) - (Current Vehicle Value × Depreciation Rate) Tax Savings = (12,000 × $0.575) - ($15,000 × 0.20) Tax Savings = $6,900 - $3,000 = $3,900

In this example, leaving the current vehicle would save you approximately $3,900 in tax deductions.

Example 2: Buying a New Vehicle

Consider purchasing a new 2018 Honda Accord with a purchase price of $25,000. The Section 179 deduction allows you to deduct the full cost of the vehicle in the first year.

Your estimated tax savings from buying this new vehicle would be calculated as follows:

Tax Savings = Purchase Price × Section 179 Deduction Rate Tax Savings = $25,000 × 1.00 = $25,000

In this example, purchasing the new vehicle would save you $25,000 in tax deductions in the first year.
