Maintenance Reserve Calculator — Frequently Asked Questions

It's money set aside for the big-ticket items that don't happen every year but always eventually happen — engine work, a transmission, an aftertreatment system repair. Setting aside a monthly amount even before anything breaks means a $6,000 repair is a non-event instead of a crisis.

Most owner-operators who stick with a maintenance reserve keep it in a separate business savings account specifically so it doesn't get spent on anything else. Treat the monthly transfer like a bill you pay yourself.

Newer trucks under warranty can use a lower number since most major failures are covered — but the reserve should grow every year as the warranty runs out and the truck ages. Many owner-operators ramp it up starting around year 3-4.

No — enter your actual expected annual oil and filter cost based on your service interval and truck type. This calculator totals what you tell it, it doesn't estimate service intervals for you.

Add it directly into your cost per mile alongside your truck payment, insurance, and fuel — a maintenance reserve that isn't in your cost per mile means every load you accept is quietly underpriced by that amount.
