The last time I looked, "released on a monthly basis" = 12 issues/year.
The last time I did arithmetic, $221.40/(12 issues + 60 issues) = $3.075/issue. Even if there were 48 months in 2013, $221.40/(48 issues + 60 issues) = $2.05/issue, not $1/issue. Perhaps your calendar and your calculator have both been owned? Best of luck to you.
