Store remodels cost, on average, $409,582, up 40 percent from costs in 2011. In 2015, 12 percent of convenience stores went through renovations.

The study also looked at the building of new stores. It cost about $4.36 million to build a new store in a rural neighborhood, and $4.87 million in an urban market. The cost of just the building was 37 percent, with the rest going to equipment, land and inventory.
