Why Your Dividend Yield Is Wrong (And How to Fix It)

What “Gross Yield” Actually Means

When a stock is listed as yielding 5%, that figure is calculated as the annual dividend divided by the current share price. It assumes you receive the full dividend — nothing deducted, nothing withheld, no friction. That assumption is almost never true.

Three things quietly reduce what lands in your account: foreign withholding tax, Canadian income tax, and commission drag on reinvestment. How much each one costs depends on your account type, your tax bracket, and your broker.

The Three Drags on Your Real Yield

1. Foreign Withholding Tax

If you hold U.S. dividend stocks, the IRS withholds 15% of every payment before it reaches Canada. In an RRSP, this withholding is waived entirely under the Canada-U.S. tax treaty. In a non-registered account, you recover it via the foreign tax credit at filing. In a TFSA, it is permanently lost.

A U.S. stock yielding 5.0% gross delivers an effective TFSA yield of just 4.25%. Over a 20-year compounding period, that 75 basis point gap becomes a substantial shortfall.

2. Canadian Income Tax on Dividends

In a non-registered account, dividends are taxable income in the year received. Eligible Canadian dividends receive the dividend tax credit, which significantly reduces the effective rate — but does not eliminate it. Foreign dividends receive no tax credit and are taxed as ordinary income.

TFSA and RRSP accounts shelter dividends from Canadian tax entirely. For non-registered holdings, your marginal tax rate matters. An investor in Ontario's 43% bracket receiving eligible Canadian dividends pays roughly 25–28% effective tax on those dividends after the credit.

3. Commission Drag on Reinvestment

If your broker charges a commission to reinvest dividends and you are not enrolled in a synthetic DRIP, every reinvestment purchase costs you a flat fee. On small positions, this drag is significant.

Commission-free brokers eliminate this drag entirely. For investors on paid-commission platforms with smaller positions, switching to a commission-free account or enrolling in a synthetic DRIP program is often the single highest-impact yield improvement available.

What Your Effective Yield Actually Looks Like

The gap between gross yield and effective yield varies by account type. This example uses a U.S. dividend stock with a 5.0% gross yield and a $9.99 reinvestment commission on a $5,000 position.

For a U.S. dividend stock, the RRSP is genuinely the most efficient account — more so than the TFSA, which most investors assume is always superior.

How to Calculate the Number That Actually Matters

Start with the gross yield. Subtract the withholding rate (0%, 15%, or 25% depending on the country and account). For non-registered accounts, apply your effective marginal tax rate on dividends. Subtract any commission drag as a percentage of your quarterly income. What remains is your effective yield.

Prospyr's Dividend Calculator handles all of this in one place. Enter your shares, dividend per share, withholding rate, and commission — and it calculates your real after-drag yield so you're comparing actual returns, not brokerage headlines.
