Why compare total ownership cost instead of one repair bill?
A repair quote only shows the next bill. Total cost of ownership adds repeat failures, labor, downtime, and the number of years you expect to keep the truck.

What this calculator does
A DPF repair-versus-delete calculator helps diesel truck owners compare different ways to handle recurring diesel particulate filter expenses. A single quote for cleaning or replacement does not show the full cost of ownership if the truck may need repeat service, spend days in the shop, or create lost-income downtime. By comparing upfront cost, repeat interval, and downtime cost across several years, you can make a more informed financial decision about the path you want to evaluate.
How it works
The calculator compares three ownership paths: replacing the DPF hardware, cleaning it when possible, or paying a one-time delete-kit cost. For replacement and cleaning, it multiplies each service-event cost by the number of expected repeat events during your remaining ownership period. It also adds labor and downtime costs to every service event so you can compare the true cost of keeping the truck on the road instead of only looking at the initial parts quote.
Formula
Projected total = recurring event cost × expected event count. Annual savings vs replacement = (replacement total − delete total) ÷ years owned.
Tips for using this calculator
- Use realistic downtime costs if the truck earns income or you rely on it daily.
- Repeat emissions failures matter more than the first repair bill when you plan to keep the truck for years.
- Cleaning may be cheaper up front but still expensive if it becomes a recurring job.
- Review inspection, warranty, and legal requirements before changing emissions hardware.
Frequently asked questions
Should I include downtime cost in the calculation?
If the truck is used for work, downtime can be as important as the parts bill. Lost trips, substitute vehicles, and delayed jobs can change the math quickly.
Is DPF cleaning always cheaper than replacement?
Cleaning is usually cheaper up front, but it may not be the lowest-cost long-term option if repeat service is frequent. The calculator helps compare those tradeoffs over time.
