I have been asked to model some cost savings, and I am struggling to think about how to model the answers, so was wondering if anyone could help.

For example

Cost Saving

Cost Saving 1

£974,000 min

£1,640,000 mean

£1,949,000 max

Cost Saving 2

£880,000 min

£880,000 mean

£1,208,000 max

Cost Saving 3

£546,000 min

£780,000mean

£819,000 max

How would I go about modelling this? I am thinking its almost the opposite of a normal simple cost risk as really you want the probability of a potential extra saving.

Does this mean that I should input them as negative costs?

Struggling with this one, as if I plug it in as normal I get a 99% chance of 3300000, P80 of say 3000000 as an example, which is kind of meaningless ? I have a 99% chance of reaching my saving, when really I need to know what the chances are of saving more (Or less)

Any help you can give as always greatly appreciated!!!!
