Side-Hustle Math · Chapter 4

Mileage Deductible

Miles times a per-mile rate the tax authority publishes — the honest running cost of the car you use for the hustle.

Enter your miles and your tax authority's per-mile rate, then press Calculate.
From the book — Chapter 4. Deduction = miles × per-mile rate. It stands in for fuel, wear, insurance, and depreciation together. Check your own country's current rate (US IRS, UK HMRC, etc.) — this tool does not know it for you.

Education only — not tax advice. Rules and records requirements differ by country; keep a mileage log.
