Matt Wensing from Stormpulse (disclaimer: I'm an investor, long story below) generously took some time off of managing the nation's severe weather risks to appear on our podcast. ( Keith Perhac couldn't be with us when we taped this, as he was celebrating the birth of his second daughter.) It's been about six months since our last episode but I think this probably makes up for it, as it's a cracker of an episode.

50 x Full Price tickets at £15

Your total possible revenue is (50 * £10) + (50 * £15) = £1250, which covers your costs nicely.

Now, if you decided that abandoning Early Bird meant that you were compelled to charge every ticket at full price, your total revenue is now (100 * £15) = £1500, or £250 more. But - and again, this is an assumption - you only really needed £1250.
