There is no way to make an accurate grading system that will meet each persons needs on an individual basis. While company A is the cheapest to Paris, it is the most expensive to Australia. However, we were able to make an average of which companies are cheaper than their competitors.

How did we grade the companies?

  1) We randomly chose 10 international destinations and recorded the cost per minute.
  2) We added up all 10 destinations. Ex: To speak 1 minute to each of the 10 destinations will cost a total of 53¢ with Sunrocket.
  3) Using the lowest amount 28¢ (Voipnet) as the common denominator, we divided 28¢ into each companies total.
    Ex: For Sunrocket, we divided 28 into 53 = .528
  4) Taking the results, we moved the decimal one place to the right, thus making the grading system from 1 to 10
    (with ten being the highest). Voipnet -Cheapest International rates. Vonage most expensive.
