Net or Gross RMR? What You Should Expect a Buyer to Pay for Your Accounts

Not all RMR is created equal. If you’re invoicing a subscriber $20 that’s not likely the number to calculate for the account during a sale.

How do you calculate your recurring monthly revenue (RMR) and what can you expect a potential buyer to pay you for your accounts? RMR is the amount of recurring charges that you charge per month, no matter whether you bill it monthly, quarter-annually or annually. So, $20 a month is the same as $240 per year; it’s still $20 in RMR.

But if you’re invoicing your subscriber $20 that’s not likely the RMR we are looking for when getting ready to calculate a price for the account on sale. You have certain fixed expenses in connection with that account, some of which may be reflected on the invoice, but other’s not.

For example, and an easy one to understand, sales tax. Not all installing security contractors charge a sales tax for monitoring, but monitoring isn’t the only RMR item. There is also lease, inspection and service plan recurring charges. So, if sales tax is 5%, that’s $1, reducing the net RMR to $19.

The most common monitoring expenses are the central station charges. This is an item that is the subject of negotiation. Central station charges can include a basic monitoring charge (that the central station retains) and other pass along charges such as guard response, radio and cellular charges, which the central station has to pay to what I call a third-party vendor.

A third-party vendor, for example, would include and AlarmNet, among others. You may also be paying a third-party vendor directly, not through the central station.

Let’s take a closer look at these charges with a few example calculations. The answers follow below.

  1. If you invoice your subscriber $20 and pay $1 to sales tax, $4 to the central station for basic monitoring, what’s the net RMR?
  1. How about if you pay the central station $8, but you know the charge includes a radio charge that the central station has to pay to the radio relay third party vendor? You ask what that charge is and find out its $5; same $1 sales tax. What’s your net RMR?
  1. Finally, you pay $9, sales tax $1 and central station $3; what’s your net RMR?

The most common calculation, though not necessarily the deal you strike with your buyer (or seller) would be: 1) $19; 2) $14; 3) $10.

Your deal may be based on your gross RMR, or it may define net RMR as what you charge less sales tax only. How can this be? Well, rest assured that a deal that defines net RMR with only sales tax deducted is going to have a lower multiple used in the price calculation.

Years ago it was common to deduct the central station basic charge, too. It’s not common in the deals I see and I don’t deduct that charge when performing a valuation of the accounts. If you think about it that means that today’s multiple is really 2 to 4 points higher than years ago. A constant multiple of 35x years ago and today means the seller is getting 2 to 4 points more multiple.

You should engage counsel before you begin your negotiations. Once you have a handshake on your deal it’s going to be hard to back-track and try to renegotiate, especially without giving up another material point.
