How much should I charge?
Short answer
Enough to cover all your costs, pay yourself a real wage, and have 15 to 20 percent left over. If your current price doesn't do that, it's too low.
The math
Total annual costs plus your target salary plus 20 percent profit, divided by billable hours per year. That hourly number, marked up for materials and risk, is your floor.
The market check
Then compare to local market. If your floor is way above market, you have a cost problem, not a pricing problem. If it's at or below, you've been undercharging and didn't know.
