What the log calculates
Entries are sorted by date, then by odometer reading. For each one the log shows the distance and days since the previous entry, and it groups services by name so you can see when each was last done. In the example, the first and last entries are 604 days and 22,990 km apart, and services cost 659.75 in total.
Costs and distance
Costs are in your own currency and are added as entered. Cost per 1,000 km or per 1,000 mi divides the total by the distance covered; the example works out to 28.70 per 1,000 km. A mile is exactly 1.609344 km (NIST SP 811, Appendix B.9, checked 16 October 2026). If a reading is lower than an earlier one, the report warns you so you can check for a typing error or a replaced odometer.
