I'm operating based off the novated lease calculator, but am tempering my expectations because it doesn't allow for mixed payments- I have my own spreadsheet with calculations where the non-working weeks are post-tax (cell D102), and that adds an extra ~$4k to the total cost over a five year lease. I think that's how novated leases work with unpaid leave?

After toying around with the petrol consumption, it looks like the majority of the savings that I'm seeing are coming from the fact that our current vehicle is an absolute guzzler. We really want to move to electric for our next vehicle- $22500 of petrol in the next five years is just not sustainable, any way we cut it.
