I'm trying to figure out if using iShares, and Vanguard ETF's are really more economical than TD e-series for my situation.

I generally save about $20,000 CAD per year. My portfolio currently contains 6 ETF's from iShares and Vanguard with MER from 0.10% to 0.50%.

Assuming I rebalance and buy once per quarter, that's 6 trades, and $5000 a quarter. I have the discount TD trading fee of $9.99.

In summary, that's about $240 in trading fees per year for $20000 of investments. Works out to be an overhead of 1.2%.

Can someone spot an error in my math? or is TD e-series really cheaper in my case?

PS: how much should one have to save per year before ETF's become truely economical than TD e-series?
