What is a Multiplier?
A. The multiplier is the goodwill factor used to value the business component of the investment. It is dependant on the risk of the business. So a very secure investment with every positive attribute will command a higher multiplier. This of course means you will pay more for the most secure investment, or in other words that your return will be lower because of the lessened risk. In other words a multiplier is your return on investment (ROI) expressed as a single number. To obtain it you divide your ROI into 100.
As well as getting points for each QSO, most contests allow you to get multipliers from certain QSOs. For example, you might get a multiplier for every different country ( DXCC entity) you work on each band during the contest. Your final score for the contact will then be calculated by multiplying the total of all your QSO points by the number of multipliers you worked. For example, if you worked 100 stations at 2 points per QSO and 20 multipliers, then your total QSO points would be 100 x 2 = 200, and your multiplier is 20, so your final score would be 200 x 20 = 4000 points.
