Two quick and simple percentage calculators.

First, how much is X% of Y. Pre-filled with some example numbers to show that 10% of 100 is 10.

And… wait for it… another one to work out what percentage X would be out of Y. Again, pre-filled with an example to show exactly the reverse of the calculation above – that 10 out of 100 is 10%.

Just on a side note, it’s a bit tricky to Use this second one in your own model because the ‘%’ at the end gets interpreted as text. This is a problem we’ll solve eventually, but in the mean time I’ve created an unformatted version – which doesn’t display the ‘%’ at the end of the answer, and will work better if you want to UseThis: http://uncharted.livesheets.com/forms/29e7c9ce79705a51a94c66ac649b66d2d0c02e2c
