Formula

Annualized = (Premium / Capital) × (365 / DTE) ($150 / $10,000) × (365 / 30) = 18.25%

What does this tool calculate?

The annualized return calculator scales short-term option premiums to a yearly equivalent so you can fairly compare puts, calls, and covered calls of different durations. The result is a theoretical p.a. rate — not a compounding guarantee.

Formula & methodology

VariableBedeutung / Meaning
Prämie / PremiumEingenommene oder bezahlte Optionsprämie
Kapital / CapitalEingesetztes Kapital (Strike × 100 oder Aktienkurs × 100)
Haltetage / Holding daysTatsächlich gehaltene Tage (DTE oder Ist-Haltedauer)
Ann. Rendite(Prämie ÷ Kapital) × (365 ÷ Haltetage)

Worked example

Prämie $200 auf eingesetztes Kapital $5.000, Haltedauer 30 Tage: (200 / 5.000) × (365 / 30) = 0,04 × 12,17 = 48,7 % p.a.

When do I use it?

When comparing options positions with different durations: annualizing normalizes everything to 365 days, making a 14-day put directly comparable to a 45-day put. Keep in mind: reinvestment and compounding are not automatically accounted for.

Frequently asked questions

Why annualize at all?

A 14-day put returning 0.8% sounds less attractive than a 45-day put at 2% — annualized the picture often reverses. Annualizing creates a uniform benchmark for yield comparison across different expirations.

Difference between covered call and cash-secured put?

For a covered call the premium is divided by the current stock price (capital tied up in the stock position). For a cash-secured put it is divided by the cash reserved (strike × 100). The capital base matters — make sure you use a consistent denominator when comparing.
