To extend your example:

Month 1. $200 Loss
Month 2. $100 Loss
Month 3. $0 Broke even
Month 4. $200 Profit
Month 5. $400 Profit.

Average Profit (including 0), $60, (excluding 0), $75.

Actually, yes I am assuming that. In practical terms, it wouldn't make
sense to average both positive and negative numbers and omit zero.

Hi Chip,

Where would zero come into the following?

1st Month: $100 loss
2nd Month: $100 loss
3rd Month: $500 profit

3 monthly average profit would be $100 profit.
