Video calling software can be purchased in monthly or annual installments (generally, you’ll see about a 10-15% cost savings with the annual price.) Many platforms include a free version and/or a free trial of paid versions lasting anywhere from 7 days to a month. The exact amount you pay will depend on the vendor, number of users/seats, and features. Generally speaking, video conferencing tools cost an average of between $28.00-$58.00/user per month.
