Yield on Cost
The annual dividend income a stock pays divided by the original price paid for that stock — showing the effective income return based on purchase price rather than current market value.
Yield on cost is calculated simply: annual dividend per share ÷ original cost per share × 100. If you paid $30 for a stock that now pays $3 annually in dividends, your yield on cost is 10%. This number grows over time as companies increase their dividends — which is why dividend growth investors focus intensely on the dividend growth rate, not just the current yield.
Critics argue yield on cost is psychologically misleading — what matters economically is the current yield and the opportunity cost of holding versus reallocating capital. A 10% yield on cost from a stock bought at $30 that now trades at $100 looks impressive, but a new buyer only earns 3% on that capital. The investor should evaluate whether reinvesting the $100 elsewhere offers better returns than continuing to hold for the locked-in 10% yield on the historical cost basis.
