What Is Yield on Cost? The Dividend Growth Payoff

Yield on cost is a simple but psychologically powerful metric that reveals the growing income stream from a long-held dividend investment. While the current dividend yield is calculated using today's stock price, yield on cost uses your original purchase price — showing you how much income you're receiving relative to what you actually paid.

How Yield on Cost Works

Yield on Cost = Current Annual Dividend Per Share ÷ Original Purchase Price × 100%

Suppose you bought a stock at $50 that paid a $1.50 annual dividend — a 3% yield at the time. Over the next 10 years, the company grew its dividend by 8% annually. The dividend is now $3.24 per share. Your yield on cost: $3.24 ÷ $50 = 6.5%. You're earning 6.5% annually on your original investment in dividends alone — more than double the yield you started with.

The stock price likely increased too (growing dividends usually accompany growing earnings), so your current yield based on today's price might still be just 2.5-3.5%. But that's irrelevant to you — what matters is the income relative to what you paid. And at 6.5% yield on cost with continued growth, you're on a path toward 10%+ yield on cost within another decade.

Why Yield on Cost Grows

Yield on cost increases every time the company raises its dividend — and your purchase price never changes. The numerator (dividend) keeps growing while the denominator (your cost basis) stays fixed. For companies that raise dividends consistently, yield on cost compounds over time just like the dividend itself.

This is the payoff for dividend growth investing: the longer you hold a consistently growing dividend payer, the higher your yield on cost climbs. A 2.5% starting yield growing at 7% annually becomes 5% in 10 years, 10% in 20 years, and 20% in 30 years. The patience required is extraordinary, but the math is inexorable.

Yield on Cost vs. Current Yield

Current yield (dividend divided by today's price) tells you what a new buyer would earn. Yield on cost tells you what you, the existing holder, are earning relative to your investment. They answer different questions: current yield guides new purchase decisions; yield on cost measures the success of past ones.

A common criticism of yield on cost: it includes price appreciation in disguise. If you bought at $50 and the stock is now $120, your yield on cost is artificially high because you're measuring against a stale price. This is technically true — but it misses the point. Yield on cost measures the income return on your actual deployed capital. You invested $50, and you're earning $3.24 per year from that investment. That's a real 6.5% annual cash return on your real capital.

Building Yield on Cost

The formula for building high yield on cost is straightforward: buy quality businesses with moderate current yields (2-4%), strong dividend growth records (7-10% annually), and wide moats that protect the earnings funding those dividends. Then hold for decades and let the compounding work.

Dividend Aristocrats — companies with 25+ consecutive years of dividend increases — are the natural hunting ground. Their track records prove they can sustain dividend growth through multiple economic cycles. The starting yield may seem modest, but the growth trajectory turns it into a substantial income stream over time.

We'd caution against chasing high starting yields at the expense of growth. A 5% yield with 2% annual growth produces a 6.1% yield on cost after 10 years. A 2.5% yield with 10% annual growth produces a 6.5% yield on cost in the same period — and is still accelerating while the high-yield, low-growth option is barely moving. Growth rate matters more than starting yield for long-term income investors.
