What is cost per transaction for extra merchant fees?

What is cost per transaction for merchant account fees ‘extras’?  A recent report cited an average of $.05 to $.14 per transaction for account fees, that is merchant fees outside of interchange and discount such as monthly statement, PCI, insurance etc. I thought the numbers were surprisingly high so I created my own report below. None of the merchants I interact with pay insurance.

Annual fees vary by processor, as do merchant statements and other extra fees. Regulatory fees are generally passed through, but some bundle this fee and some are charging on a monthly basis. The numbers below are neither the lowest or highest a merchant might pay.

transactions per month 100 12 1200
annual fee $79.00 1 $79.00
statement fee $8.00 12 $96.00
regulatory $3.95 12 $47.40
total extra fees $222.40
Cost per transaction $0.19
transactions per month 1000 12 12000

Cost per transaction $0.02

The cost per transaction is greatly skewed by the number of transactions processed. The comparable report accessed data for over a million merchants. Our report uses common numbers we make available to merchants.
