Odometer Mileage Log Builder: Turn Start & End Readings into a Clean Annual Report
An October oil-change receipt with 28,430 on the odometer is evidence. A guessed January 1 reading is not. This worksheet projects both year endpoints from that receipt and your weekly-mile estimate, then labels the results as estimates.
Look for dated odometer readings on oil-change invoices, tire receipts, state inspections or dealer service records. Two dated readings are stronger than one. If you can get them, use the actual records rather than a weekly average.
The IRS rate table gives the cents-per-mile amounts. It does not decide whether a particular drive is deductible. Write down why the drive happened before relying on any calculation.
How this worksheet works
The worksheet adds or subtracts estimated weekly miles for the number of days between the receipt and each year endpoint. This is a rough reconstruction, not a verified reading and not a substitute for a business-trip log.

Keep the records behind the number
Keep a copy of the source receipt and note your estimation method. If the car was bought, sold or placed in business use during 2026, the relevant period may not be January 1 through December 31.
72.5 cents per business mile for January 1 through June 30, 2026; 76 cents for July 1 through December 31, 2026.

Drive every week?
Milevaro records trips you start with one tap and exports CSV or PDF reports. Every feature is free for 14 days; then $39.99/year or $3.99/month. Existing trips remain viewable and CSV export stays free if you do not subscribe.
Milevaro reports are records of trips logged by the user. They are not IRS-certified and do not guarantee a tax deduction. A deduction lowers taxable income; it is not direct cash back. The estimated deduction is business miles multiplied by a user-set rate and is an estimate, not tax advice. Consult a qualified tax professional.
