This is one of the most common questions we receive. Based on historical estimates, an optimally diversified portfolio of ETFs is expected to generate between 3-8%, depending on how much risk you're willing to take.
The 3-8% might disappoint you, but it doesn't really matter what we think the expected return is going to be because no one can predict it.

That's why you should focus on what you can control:
1. Costs - Keep your costs low. A lot of traditional investment advisors have expensive and hidden fee structures. We don't. Check out our simple pricing page here.
2. Time horizon - The longer the better. Have a medium-long time horizon (5-10+ years) and stick to your plan.
3. Your risk (and the emotions that come with it) - Don't try to time the market as study after study shows that it's impossible to do that. Instead, find a suitable risk profile and contribute regularly to your plan to benefit from dollar-cost averaging. When you invest fixed sums at regular intervals, you pick up more units when the prices are low and fewer units when the prices are high.
