How much does fabric on average cost a yard?

depends on the type of fabric anywhere from 1.99 a yard to the most I heard of 145.00 a yard.
It depends on the type of fabric you want. At some discount stores, like certain Wal-Marts or Joann's Fabrics, you can get fabric for $1 per yard. If you're looking for high-end designer (that's home designer, not clothing) fabrics for curtains or furniture you could end up paying several hundred dollars per yard. A reasonable average for what you'd find in any city is probably between $5 and $15 per yard.
