The best and cheapest option is a public bus, the Perum Damri bus. The last bus departs at 12pm to Medan city.

The Kualanamu airport website has a page dedicated to airport transfer information. Several options are listed there along with the approximate prices for each solution. Being the first Sumatran airport to be directly linked to the city centre via rail, I think the Airport Train might be a good solution to reach Medan city. According to the linked website the cost of a train ride is (as of November 15th (I'm assuming) 2014) 80.000Rp
. Buying several tickets at once entitles you to proportionally discounted fares. Below is a screenshot of the linked website with more information on the Airport train:
More information can be found on the website of Railink the company managing the trains. For completeness sake, your other options are buses, Airport shuttle, taxis and renting a car.
