A 48.7% Annualized Wheel Yield Is Not a Forecast
A $2 premium on a 30-day $50 cash-secured put is 4.0% for the contract period and 48.7% when simply annualized—but assignment, downside and idle capital make that display very different from an expected return.

Start with the contract-period return
Annualizing an option premium makes contracts with different expirations easier to compare, but it does not turn one premium into a forecast. A wheel scorecard should first show what actually exists: the premium received, the capital committed and the number of days in the contract. Only then should it show an annualized figure—and label the assumptions behind it.
Two displays, two meanings
Contract-period premium yield = premium ÷ committed capital. Simple annualized display = contract-period yield × 365 ÷ days to expiration. The second line assumes the same terms could be repeated immediately for a full year; it is a comparison tool, not an expected return.
Worked example: a 30-day cash-secured put
| Measure | Calculation | Result |
|---|---|---|
| Cash collateral | $50 strike × 100 shares | $5,000 |
| Premium received | $2.00 × 100 shares | $200 |
| Contract-period premium yield | $200 ÷ $5,000 | 4.0% |
| Simple annualized display | 4.0% × 365 ÷ 30 | 48.7% |
| Expiration breakeven | $50 strike − $2.00 premium | $48.00 per share |
The Options Industry Council gives the cash-secured put breakeven as strike price minus premium. That $48 breakeven is only a 4.0% cushion below the $50 strike. If assignment occurs and the shares later trade at $40, the position is $8 per share below the $48 net basis: an $800 unrealized loss on 100 shares, before costs or taxes. The 48.7% display did not predict that outcome; it merely stretched one 4.0% period across 365 days.
The repeatability assumption is doing the heavy lifting
A full year will not necessarily contain twelve identical 30-day trades. Premiums, volatility, strikes and share prices change; capital can sit idle; positions can be assigned; and losses can absorb several earlier premiums.
Covered calls add an upside cap
| Measure | Calculation | Result |
|---|---|---|
| Call sold | $52 strike; $1.50 premium | $150 received |
| Premium yield on stock cost | $150 ÷ $4,800 | 3.13% |
| Expiration breakeven | $48 − $1.50 | $46.50 per share |
| Maximum expiration gain if assigned | ($52 − $48 + $1.50) × 100 | $550, or 11.46% |
The Options Industry Council describes the covered-call trade-off directly: a higher strike preserves more upside but produces less premium and therefore less downside cushion. FINRA likewise notes that a covered-call writer receives premium but can lose the shares’ upside appreciation if exercise requires a sale at the strike. A premium-yield percentage by itself omits both the stock downside and the capped upside.
Use a three-line wheel scorecard
- Cash result: premium dollars actually received, shown per share and per contract.
- Capital efficiency: contract-period premium yield on cash collateral or stock cost; any annualized display is separately labelled as a simple scenario.
- Stock economics: expiration breakeven, downside at several stock-price scenarios, and—on a covered call—the maximum expiration gain and foregone upside above the strike.
The useful comparison
Compare like with like: the same capital base, the same day count and the same assignment assumptions. Treat annualization as a normalized display, while judging the wheel through both option cash flow and the stock outcome.
This framework is deliberately pre-tax and excludes commissions and fees. Those items vary by account, broker and jurisdiction and reduce the net result. It also avoids treating premium as free income: an option seller accepts an obligation, and assignment can convert the cash-secured-put leg into stock ownership or call away covered shares.
