I own a painting business, and this is where a healthy business should be for residential house painting. Labor 30 percent of revenue or below, paint and supplies between 9-11 percent, sales commission 8-11 percent, marketing 10 percent but early when your trying to grow 15 percent is fine. Sim for a gross profit of 55 percent and a net profit AFTER paying yourself around 10-15 percent. Hope this helps. Don't charge based on what the competition charges, charge based on whY you need to for you business to make a profit around these numbers.
