There are no universal standards as to how a company should grow. As noted by TechCrunch, accelerators like Y-Combinator find that a 5 to 7 percent growth rate for companies is great, with 10 percent being excellent. However, this represents early-stage levels.

The article also analyzed more than 70 publicly-traded tech firms and found that 20 percent annual growth has kept them sustainable at a healthy level. Determine what this will look like for your business in terms of revenue or increased sales volume and it will give you a better feel for your three- to five-year plan.
