Was the cost of the war higher for the North or the South?

The cost of the Civil War was much higher for the South. Most of the fighting took place in the south which took a higher toll financially. Besides, most of the factories and rail lines were in the north which made it easier to get supplies and food to Union troops. After Sherman's march to the sea, the South was in ruins. He burned and destroyed everything in his path and the South had to pay for that in years to come during Reconstruction.
