A F&F is based upon the remaining payments due, plus 12 if there is likely to be equity release. It can be rounded down a little, depending on the time left and the amount to be repaid by the IVA against the total debt --- the higher the return and time saved, the more likely the creditors will be content to lose a little more. It is a very imprecise science and I have seen high offers refused as well as low ones accepted.
I might also add that the circumstances have a bearing as well.
My opinions are merely that .. opinions based on experience. Always seek professional advice.

Unless circumstances dictate otherwise it has to be worthwhile for creditors. As foggy says a figure close to what they could expect is the starting point.
