Graham vs dividend yield ceiling: which one should you use?
Compare the Graham number with a dividend yield price ceiling using one stock example, and learn how to combine them into a single buy limit.
A Graham ceiling and a dividend yield ceiling answer different questions. The Graham number asks what a company is worth based on earnings and book value. The dividend yield ceiling asks what price gives you the cash income you want. For most DIY dividend investors, the safest buy limit is the lower of the two.
This guide compares both methods side by side with one stock, shows where each one breaks down, and explains how to combine them into a single price you can set in your brokerage as a limit order. It is educational content, not personalized investment advice.

What each method actually measures
Benjamin Graham’s formula estimates a ceiling from two accounting figures: earnings per share (EPS) and book value per share (BVPS). The constant 22.5 comes from his rule of thumb that a defensive investor should not pay more than 15 times earnings or 1.5 times book value (15 × 1.5 = 22.5).
The dividend yield ceiling ignores accounting entirely. It starts from the annual dividend per share and divides it by the yield you require. If you want a 5% yield and the stock pays $2.40 a year, the most you should pay is $48.
Graham ceiling = √(22.5 × EPS × BVPS) Dividend ceiling = Annual dividend per share ÷ Target yield
A worked example with one stock
Assume a US industrial company has EPS of $4.00, book value of $30.00 per share, and pays $2.40 in annual dividends. Its stock trades at $55.
Graham: 22.5 × 4.00 × 30.00 = 2,700, and the square root is about $51.96. Dividend: $2.40 ÷ 0.05 = $48.00. The stock at $55 is above both ceilings, so neither method supports a buy today.
Taking the lower value ($48.00) and applying a 10% margin of safety gives $43.20. That is the price at which this stock fits both frameworks with a cushion.
- Graham ceiling: about $51.96
- Dividend ceiling at 5% target yield: $48.00
- Conservative limit after a 10% margin of safety: $43.20
Where each method fails
Graham’s formula punishes asset-light companies. Software, consumer brands, and many service businesses have low book value, so the formula returns a ceiling far below the market price even when the business is excellent. It also fails when EPS or book value is negative.
The dividend ceiling fails for companies that pay little or no dividend, and it can mislead when a dividend is about to be cut. A stock with a sky-high yield may simply be priced for trouble. Always check that the payout is covered by earnings or cash flow.
- Use Graham for mature, asset-heavy businesses such as industrials, banks, and utilities.
- Use the dividend ceiling for steady payers where income is the goal.
- Skip either method when its inputs are negative, one-off, or distorted.
How to combine them into one buy limit
You do not have to pick a winner. Compute both, discard any method whose inputs look unreliable, and take the lower of what remains. Then apply your margin of safety. This gives you one number to compare with the market price each month.
- Pull EPS, book value per share, and the annual dividend from the latest filings.
- Compute the Graham ceiling and the dividend ceiling.
- Take the lower valid ceiling.
- Multiply by (1 − margin of safety), for example 0.90 for 10%.
- Place a limit order at or below that price, or wait until the market comes to you.
Buy limit = MIN(Graham ceiling, Dividend ceiling) × (1 − Margin of safety)
