You have two options: use the calculator above to optimize your mileage deduction strategy, or follow this guide to manually calculate business mileage tax savings.
The Formula
| Method | Formula |
|---|---|
| Standard Mileage | Business Miles × IRS Rate per Mile |
| Actual Expenses | (Total Vehicle Costs × Business %) – Personal Use |
| Tax Savings | Deduction Amount × Tax Rate |
Step-by-Step Calculation
Here’s a complete mileage deduction comparison.
Step 1: Calculate Standard Mileage Deduction
Use IRS standard rate method:
| Mileage Type | Miles | Rate | Deduction |
|---|---|---|---|
| Business Miles | 12,000 | $0.655 | $7,860 |
| Commute Miles | 3,000 | Not deductible | $0 |
| Personal Miles | 5,000 | Not deductible | $0 |
| Total Deduction | 12,000 | – | $7,860 |
Calculation: 12,000 miles × $0.655 = $7,860
Step 2: Calculate Actual Expense Method
Track and allocate all vehicle costs:
| Expense Category | Annual Amount |
|---|---|
| Fuel | $3,200 |
| Insurance | $1,800 |
| Maintenance & Repairs | $1,500 |
| Registration & Taxes | $400 |
| Depreciation | $4,500 |
| Total Vehicle Costs | $11,400 |
| Business Use % | 60% |
| Business Deduction | $6,840 |
Calculation: $11,400 × 0.60 = $6,840
Step 3: Compare Methods and Calculate Tax Savings
Choose the better option and compute savings:
| Method | Deduction | Tax Savings (24%) |
|---|---|---|
| Standard Mileage | $7,860 | $1,886 |
| Actual Expenses | $6,840 | $1,642 |
| Best Option | Standard | $1,886 |
Final Answer: Standard mileage saves $1,886 in taxes
What This Means
In this scenario, standard mileage delivers $244 more tax savings than actual expenses. The standard method also requires less record-keeping—just track your miles rather than every vehicle expense receipt.
