Although the online Global Calculator tool gives you lots of graphs and 40 levers to explore, you may want more detail about a particular sector or how the Calculator works. We have published the full Excel model behind the online tool so that you can examine the methodology and assumptions that have been used. If you don't agree with them, you can change them and see the impact that has.
