Return on Investment

dollar_image.jpg

The cost of Rollie Technology tank monitors and the monthly monitoring fee are, by far, the lowest in the industry.  This allows you to get a quick return on your investment.  In most cases, the payback period is less than 3 years and the return on investment is well in excess of 30%. 

A detailed analysis of return on investment for each type of monitor is as follows:


Fuel Oil Monitor

The cost of delivering home heating oil is generally between 18 and 26 cents per gallon.  By making yourdeliveries more efficient,  the use of wireless tank monitors will, on average, allow you to make a minimum of one less delivery to each customer over the course of the year.  A study by Angus Energy and Warm Thoughts Communications concluded that, on average, the use of a tank monitor could reduce the number of deliveries to each customer by 1.5 per year. 

Let’s assume that your average customer uses 800 gallons per year and that you are making 5 deliveries to that customer each year.  If you are able to cut the number of deliveries to 4, that’s a 20% reduction in deliveries and delivery costs.  Here are the numbers for that customer:

Cost of Rollie Wireless Tank Monitor in year 1 ($89 + $10) = $99

Average delivery cost per customer per year (800 gallons x 22 cents per gallon) = $176

Savings per year from use of Rollie Wireless Tank Monitor ($176 x 20 percent) = $35.20

Based on these numbers the payback period is 2.5 years ($89 / $35.20) and the return on investment is 40% ($35.20 / $89) in year one and 28.3% ($35.20 - $10 /$89) in all subsequent years.   While those numbers are impressive, we believe that the savings are much greater for two reasons:

  1. You’ll avoid having to absorb significant extra costs when a customer runs out of oil.
  2. The extra marginal deliveries you need to make without the wireless monitor cost more than the other deliveries.  Those last deliveries are the ones where you‘ll likely be paying your driver overtime or need to purchase and run an additional truck.


Propane Monitor

The cost of delivering propane is generally between 25 and 35 cents per gallon.  By making your deliveries more efficient,  the use of wireless tank monitors will, on average, allow you to make a minimum of one less delivery to each customer over the course of the year. 

Let’s assume that your average customer uses 1000 gallons per year and that you are making 5 deliveries to that customer each year.  If you are able to cut the number of deliveries to 4, that’s a 20% reduction in deliveries and delivery costs.  Here are the numbers for that customer:

Cost of Rollie Wireless Tank Monitor in year 1 ($119 + $10) = $129

Average delivery cost per customer per year (1000 gallons x 30 cents per gallon) = $300

Savings per year from use of Rollie Wireless Tank monitor ($300 x 20 percent) = $60

Based on these numbers the payback period is 2.15 years ($129 / $60) and the return on investment is 46.5% ($60 / $129) in year one and 38.8% ($60 - $10 /$129) in all subsequent years.   While those numbers are impressive, we believe that the savings are much greater for two reasons:

  1. You’ll avoid having to absorb significant extra costs when a customer runs out of propane.
  2.  The extra marginal deliveries you need to make without the wireless monitor cost more than the other deliveries.  Those last deliveries are the ones where you‘ll likely be paying your driver overtime or need to purchase and run an additional truck. 


Waste Oil / Septic Monitor

The cost of picking up waste oil is generally between 25 and 30 cents per gallon.  By making your pickups more efficient, the use of wireless tank monitors will, on average, allow you to make a minimum of one less pick up to each customer over the course of the year. 

Let’s assume that your average customer generates 500 gallons of waste oil per year and that you are making 3 pickups to that customer each year.  If you are able to cut the number of pickups to 2, that’s a 33% reduction in pickups and pickup costs.  Here are the numbers for that customer:

Cost of Rollie Wireless Tank Monitor in year 1 ($89 + $10) = $99

Average delivery cost per customer per year (500 gallons x 27.5 cents per gallon) = $137.50

Savings per year from use of Rollie Wireless Tank Monitor ($137.50 x 33 percent) = $45.38

Based on these numbers the payback period is 1.96 years ($89 / $45.38) and the return on investment is 51% ($45.38 / $89) in year one and 39.8% ($45.38 - $10 /$89) in all subsequent years.   While those numbers are impressive, we believe that the savings are much greater for two reasons:

  1. You’ll avoid having to absorb the extra costs when you have to make a special trip because the customer’s tank is full.
  2. The extra marginal pickups you need to make without the wireless monitor cost more than the other deliveries.  Those extra pickups are the ones where you‘ll likely be paying your driver overtime or need to purchase and run an additional truck.
