Fleet Vehicle Replacement Calculator (Free)
Decide whether to keep or replace a fleet vehicle by comparing the cost to keep (maintenance + downtime + ownership) vs the cost to replace (new ownership payment + lower maintenance + lower downtime).

How the model works
We project “keep” costs forward by growing maintenance over time and keeping insurance + ownership flat (you can edit them). We compare cumulative cost over your horizon to the “replace” path (new monthly cost + upfront fees).
Best practices
- Use conservative assumptions: if replacement wins even with conservative inputs, it’s usually a strong signal.
- Add downtime realistically: downtime is where old vehicles become extremely expensive.
- Measure CPM quarterly: if CPM is rising fast, replacement timing becomes obvious.
Replacement Calculator FAQ
What if my current vehicle is fully paid off?
Set “ownership/depreciation” to $0. If maintenance and downtime are still high, replacement can still win.
Should I model resale value?
You can approximate resale value by entering it as a negative “upfront fee” (a credit). For a cleaner model, keep it separate in your internal analysis.
What horizon should I use?
Common horizons are 24–60 months depending on how long you keep vehicles. Use the horizon that matches your replacement cycle.
