2. Maintenance & Max Pricing

The "Max Price" Strategy

You will notice the calculator asks for the Max Oil Filter Price and Max Diesel Filter Price. Why the maximum?

Because parts prices fluctuate wildly depending on where you break down or where you get serviced. By entering the absolute maximum price you expect to pay (worst-case scenario) instead of the cheapest sale price, you build a safety net into every single quote.

How the Consumables Math Works

You don't buy an oil filter every single trip, but every trip puts wear on that filter. The calculator spreads the cost of your oil changes across your mileage so you are always putting money away for the next service.

It then multiplies that Cost Per Mile by the total miles of your current trip to show you exactly how much of your paycheck needs to be saved for the next PM (Preventative Maintenance).

Avg Repairs Cost (Cents Per Mile)

Separate from oil and filters, you have tires, brakes, and unexpected breakdowns. You must account for this in your rate.

• Newer Trucks under warranty: Usually around $0.10 to $0.15 per mile.
• Older Trucks (out of warranty): Usually around $0.20 to $0.35+ per mile.

Find what you spent on total truck repairs last year, divide it by the total miles you drove last year, and enter that decimal (e.g., 0.25) into the Avg Repairs Cost box.
