In plain English

Yield on cost = current annual dividend per share ÷ your original purchase price × 100

It shows how your personal income has grown compared with what you invested.

Example

You bought a stock at $50 when it paid $1.50 a year (3%). Ten years later it pays $3.00 a year. Your yield on cost is $3.00 ÷ $50 = 6%, even if the stock’s current yield for new buyers is only 3%.

Why it matters

It is a motivating way to see dividend growth working for you over time.

Common mistakes

  • Treating it as your return. It ignores the current price and what the money could earn elsewhere.
  • Comparing yield on cost with the yield of a new investment.
