Stock Buyback Yield Calculator: Buybacks Over Market Cap
Work out a stock's buyback yield — the often-overlooked second engine of shareholder return alongside dividends, and the figure that completes the picture of capital being returned to shareholders.

Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Buyback yield | Non-return share |
|---|---|---|
| $50M buyback · $1B cap (5%) | 5.00% | 95.00% |
| $2B buyback · $80B cap (2.5%) | 2.50% | 97.50% |
| $10M buyback · $500M cap (2%) | 2.00% | 98.00% |
| $80B buyback · $1T cap (8%) | 8.00% | 92.00% |
How This Calculator Works
Enter trailing-twelve-month buyback spending and current market capitalization. The calculator divides one by the other and multiplies by 100 to give buyback yield. Add dividend yield for total shareholder yield — the full capital return measure.
The Formula
Part as a Percentage of a Whole
Part is the portion, Whole is the total it belongs to
Worked Example
A company spending $50M on buybacks against a $1B market cap posts a 5% buyback yield. Combined with a 2% dividend yield, total shareholder yield reaches 7% — comparable to a 7% bond, except shareholders also own the underlying business and its growth. Some large-cap names (Apple, banks) have run 4% to 8% buyback yields for years, doing more for total return than dividends alone.
Key Insight
Buyback yield captures what dividend yield misses — companies that prefer buybacks to dividends often look like 'low yield' stocks on the dividend screen even though they're returning enormous capital. Net buyback yield (gross buybacks minus issuance) matters even more: tech companies issuing large stock-based compensation may run high gross buybacks but near-zero net buybacks, neutralizing the apparent capital return.
Frequently Asked Questions
How is buyback yield calculated?
Divide annual buyback spending by market cap, then multiply by 100. A $50M buyback program at a $1B market cap is a 5% buyback yield.
How does buyback yield differ from dividend yield?
Both measure capital returned to shareholders. Dividends pay cash to all holders; buybacks reduce share count and lift per-share metrics. Many companies prefer buybacks for tax efficiency — buybacks defer the capital-gains tax until shareholders sell.
What is total shareholder yield?
Dividend yield + buyback yield = total shareholder yield. The complete measure of capital being returned. Many academic studies show total yield correlates with future returns more strongly than dividend yield alone.
What is net buyback yield?
Gross buybacks minus stock issuance, divided by market cap. Companies issuing large equity-based compensation may have high gross buybacks but near-zero net — the issuance neutralizes the buyback effect on share count.
Are buybacks always good for shareholders?
Generally yes when executed at reasonable valuations. Buying back overvalued shares destroys value; buying back undervalued shares creates value. Boards typically authorize buybacks during downturns when the stock is cheap — though execution timing varies.

Methodology & Review
Buyback yield is annual buyback spending divided by market capitalization, multiplied by 100. Combined with dividend yield, this gives total shareholder yield — the full capital return to shareholders. Net buyback yield (gross buybacks minus stock issuance) is the more honest measure for companies that issue large equity-based compensation.
