In general, how do you decide whether to pay a product fee or go for a fee saver?

I use " whatsthecost " and work out how much we will pay over the period of the fix including the Fee or No Fee and see how much we owe at the end of the 2/5 years by clicking on the " Details " link and going down the table of months for 24 or 60 months.
Not always easy to work out so post details if you want so others can help.

I used to use whatsthecost  but I wanted to do some complicated stuff so now have a  spreadsheet for a few problems.

With whatsthecost tool  for the odd calculation the trick is to use the interest only option.
get 2 tabs up stick in the mortgage, rate, term for both options(adding the net fee)
pick the biggest payment and round up to the nearest £1

change
to interest only
Term to length of fix
payment  to the one above( or the planned payment)
Calculate

It then shows the amount owing at the end of the fix.
lowest is better

That does a like for like cash flow, the starting cash position is the same, the monthly outflow is the same.
end result is what you owe.

It abstracts everything into a single number that everyone should understand and could ask their broker

Which mortgage leaves me with the smallest debt at the end of the fixed term for the same money out of my pocket?
