This is a really vague question. To tell you the truth EPC alone doesn't tell you much. I have got less than $0.01 EPC and I've had over $10+ EPC
What really matters is your ROI. If you spend $15 per click and make $15.01 EPC then you could have a high EPC but not a high ROI.
A million things can effect your EPC and your ROI. Traffic source, offer, landing page, niche and so on.
