Laundry service varies from ship to ship. Some ships have laundry rooms, where you can wash, fold, and dry your cloths. While other ships require you to bag your laundry and your room steward will usually provide next day service. Some ships charge by the pound, others charge by the bag...I've seen both. However if you book a suite, laundry and clothes pressing is usually provided free.
If your cruise is for 7, 10, or 14 days just pack enough clothes. To answer your question: laundry service could possibly be very expensive depending on the cruise line.
