Regarding "ERR, a merchant retention tool," by Bob Schoenbauer, The Green Sheet, Sept. 28, 2009, issue 09:09:02, we received the following note:
Bob Schoenbauer recently wrote a nice article about ERR [Enhanced Recover Reduced], but there was a slight math error. Using ERR, you have the option to assess a surcharge to the merchant's downgraded sales volume. The surcharge is an ISO-defined percentage that is applied to the downgraded sales volume of participating merchants. Bob did a great job of explaining that.
In the ERR article, the rate for the transaction came in at 4.06%, but that is incorrect. The proper formula for ERR, according to the FDR ERR Sell Sheet available to FDR clients is:
Qualified discount rate charged, i.e. 1.69% - (minus) Nonqual-ified interchange rate, i.e. 2.30% + $0.10 + (plus) Difference between nonqualified interchange rate and "base" qualified rate (i.e. 2.30% + $0.10 - 1.54% + $0.10 for CPS Retail) + (plus) ERR surcharge %, i.e. 1.00% = (1.69% x sale amount) minus (2.30% + $0.10 cents x sale amount) plus (0.76% x sale amount) plus (1.00% x sale amount) = 1.15% profit on the individual sale.
(By the way, the $0.10 transaction fee of the interchange was dropped off for ease of math in the example below.)
The "rate" of that sale would ultimately be 3.45%, which is 1.15% plus the nonqualified interchange of 2.30% (interchange for the EIRF credit sale).
The calculation that was done appeared to be the actual interchange rate (2.30%) plus the ERR rate (1.00%) plus the difference in the two interchange categories (2.30% - 1.54% = 0.76%) which came to 4.06%.
Instead, it should be the qualified discount rate (1.69%) plus the difference between the two interchange categories (0.76%) plus the ERR rate (1.00%), or 3.45%.
Basically, an easy way to think about ERR is as follows:
On a $300 sale, that would look like this:
The profit actually comes to around 1.12%. You have to take into account you billed 1.69% plus 0.76% plus 1% (3.45%) and still had an expense of 2.30% + $0.10 for the interchange, or an effective rate of 2.33%.
3.45% - 2.33% = your 1.12% profit
Otherwise, it was a nice article. Well done, Bob!
