It’s a good article to start thinking about taxes and inflation and how they affect your returns, but obviously I don’t agree with just adjusting your rates of return (the “shorthand metric” at the end), that is way too simplistic and downright misleading. He also misses some points about taxable accounts, many people do.
Yes the dividends are taxed, so that’s a haircut, but if you’re a low income Canadian invest your non-registered portfolio in Canadian stocks, the dividend tax credit can be a boon. If you’re high income, avoid dividend paying stocks, go for growth in non-registered accounts. That growth is tax-free until you sell, and you get the capital gains exemption when you do. That tax break is lost in registered accounts.
Anyway, not so simple, but luckily Canadians have the MoneyReady App Maybe I should write a blog post..
