Most people talk of the percentage that spam makes up of all email sent, which is a useful rough measure of the global impact of spam. The actual percentage in any inbox will of course vary hugely, depending on the average rate at which people receive other email.
A better measure to gauge the impact on your own inbox might be the average rate at which spam is received by an average email account, since this is independent of the expected normal email load. A measure that avoids masking huge rises in spam would be the ratio of spam to normal email, since this will rise linearly with spam volume rather than tending to 100% as current spam measures do.
