Annualized Return Calculator
Turn an options premium into two numbers: what the trade actually returns over its own life, and what that rate would be if it repeated for a year. The second number is a comparison device, not income you should expect to collect.
Capital is your stock cost basis × 100 per contract.

Annualizing assumes the same trade is available on the same terms, cycle after cycle, with no idle capital and no losing cycles. That combination is rare. Premiums move with implied volatility, strikes you are willing to trade are not always there, and a single bad cycle can erase several good ones. Treat the annualized figure as a way to line up trades of different lengths against each other — not as an expected yearly return.

Pick the Position Type
Covered call or cash secured put. The only thing this changes is which capital the return is measured against — your cost basis in the shares, or the cash securing the put.
Enter the Capital Base
For a covered call, enter what you actually paid per share, not the current price. For a cash secured put, the strike is the capital base — there is no basis to enter.
Add Premium, Contracts and DTE
Use the premium per share as quoted, not the total dollar credit. Days to expiration drives the annualization factor, so a small change there moves the annualized number a lot.
Read Static First
The static return is the money the trade can actually make over its own life. Size the position off that. Use the annualized figure only to rank one candidate against another.
The Formulas
- $ Capital (covered call): Cost Basis x 100 x Contracts
- $ Capital (cash secured put): Strike x 100 x Contracts
- + Total Premium: Premium x 100 x Contracts
- % Static Return: Total Premium / Capital x 100
- % Annualized: Static Return x (365 / DTE)
- % If-Called (covered call): (Premium + Strike - Basis) x 100 x Contracts / Capital x 100
Why Annualizing a 30-Day Premium Is a Comparison Tool, Not a Forecast
The arithmetic is simple: take the return earned over the trade's own life and multiply it by 365 / DTE. A 2.0% return on a 30-day option becomes 24.3% because the formula assumes 12.2 identical cycles in a year. Nothing about that multiplication is wrong. What is wrong is reading the output as income.
Four things have to hold for the annualized number to arrive in the account, and they rarely hold together:
- 1 The same premium is there every cycle. Premium tracks implied volatility. A strike that pays 2.0% in a nervous month may pay 0.8% in a quiet one, and the calm months are the more common of the two.
- 2 The capital never sits idle. Settlement, assignment, and waiting for a strike worth selling all create gaps. Ten dead days a cycle turns twelve cycles a year into nine.
- 3 No cycle loses money. Annualizing a winning cycle while quietly excluding the ones where the stock fell through the strike produces a number no statement will ever match.
- 4 The capital base survives the cycle. A covered call that gets assigned ends with cash, not shares, at a different basis. The next cycle starts from somewhere else entirely.
There is one job the annualized figure does well, and it is worth the arithmetic. A 1.2% return over 21 days and a 2.1% return over 45 days cannot be compared directly — one ties up capital for twice as long. Put both on a common time base (20.9% and 17.0% annualized) and the shorter trade is clearly the better use of the same money, which the raw percentages hid. That is what annualizing is for: ranking candidates, not projecting a year.
A note on convention: this calculator uses simple annualization (static return x 365 / DTE), which is what brokerage screens and most option chains show. Compounding the same rate across the year gives a larger number and inherits every assumption above, plus the assumption that each premium is immediately reinvested at the same rate. The calculator shows it in small print for contrast, deliberately.
What the Annualization Factor Does
The shorter the trade, the larger the multiplier. This is arithmetic, not evidence that short-dated options pay better — a 7-day option does not carry the same premium as a 30-day one, so the left-hand rows are not achievable at the returns shown.
| Days to Expiration | Cycles per Year (365 / DTE) | 1.0% Cycle Return Annualized | 2.0% Cycle Return Annualized |
|---|---|---|---|
| 7 | 52.1 | 52.1% | 104.3% |
| 14 | 26.1 | 26.1% | 52.1% |
| 21 | 17.4 | 17.4% | 34.8% |
| 30 | 12.2 | 12.2% | 24.3% |
| 45 | 8.1 | 8.1% | 16.2% |
| 60 | 6.1 | 6.1% | 12.2% |
| 90 | 4.1 | 4.1% | 8.1% |
Two Worked Examples
Cash Secured Put
Sell one $50 strike put for $1.00 with 30 days to expiration.
- Capital: $50 x 100 = $5,000 of reserved cash
- Total premium: $1.00 x 100 = $100
- Static return: $100 / $5,000 = 2.00%
- Annualized: 2.00% x (365 / 30) = 24.3%
Covered Call
Own 100 shares at a $100 basis, sell one $105 call for $2.00 with 30 days to expiration.
- Capital: $100 x 100 = $10,000 in shares
- Static return: $200 / $10,000 = 2.00% (24.3% annualized)
- If called away: ($2.00 + $105 - $100) x 100 = $700, or 7.00%
- If-called annualized: 85.2%
Why 85.2% Is the Number to Distrust
The 7.00% if-called return is real, but $500 of it is a one-time capital gain from the $100 basis up to the $105 strike. That gain cannot repeat — once the shares are assigned the position is closed and the capital comes back as cash needing a new home at a new basis. Annualizing it multiplies a non-repeating event by 12.2. The 2.00% static return is the part of the trade that is genuinely repeatable, which is why it is the more useful of the two figures even though it is much smaller.
Annualized Return Formulas Reference
The calculator does the arithmetic, but here are the formulas for verification or spreadsheet use.
| Metric | Covered Call | Cash Secured Put | Example ($50 put, $1.00, 30 DTE) |
|---|---|---|---|
| Capital Committed | Basis x 100 x Contracts | Strike x 100 x Contracts | $50 x 100 = $5,000 |
| Total Premium | Premium x 100 x Contracts | Premium x 100 x Contracts | $1.00 x 100 = $100 |
| Static Return | Premium / Basis x 100 | Premium / Strike x 100 | $100 / $5,000 = 2.00% |
| Annualized Return | Static x (365 / DTE) | Static x (365 / DTE) | 2.00% x (365 / 30) = 24.3% |
| If-Called Return | (Premium + Strike - Basis) / Basis x 100 | Not applicable | $100 basis, $105 strike, $2.00: 7.00% |
| Compounded (contrast only) | ((1 + Static)^(365 / DTE) - 1) x 100 | ((1 + Static)^(365 / DTE) - 1) x 100 | (1.02^12.17 - 1) = 27.2% |
Frequently Asked Questions
How do you calculate annualized return on an options trade?
Annualized return = (premium / capital committed) x (365 / days to expiration) x 100. Sell a $50 strike cash secured put for $1.00 with 30 days to expiration: capital is $50 x 100 = $5,000 and the premium is $100, so the static return over the life of the trade is 2.00%. Annualized, that is 2.00% x (365 / 30) = 24.3%. For a covered call the capital is your stock cost basis x 100 per contract rather than the strike.
Why do annualized options returns overstate realistic income?
Because annualizing multiplies one cycle by 365 / DTE, which assumes you repeat the identical trade on identical terms all year — roughly twelve times for a 30-day option. Premiums move with implied volatility, capital sits idle between cycles, acceptable strikes are not always available, and some cycles lose money. The annualized figure exists so trades with different holding periods can be compared on a common time base. It is not a projection of what an account will earn.
Should you use the stock price or the strike as the capital base?
For a covered call, use your cost basis x 100 per contract — that is the capital already committed to the shares the call is written against. For a cash secured put, use the strike x 100, because that is the cash reserved to buy the shares if assigned. The choice matters: a put struck well below the current share price reports a higher yield against the strike than against spot, and the two are not interchangeable when you are comparing trades.
What is the difference between static and if-called return on a covered call?
Static return counts the premium only: premium / cost basis. It is what you earn if the stock goes nowhere and the call expires worthless. If-called return adds the capital gain from your basis up to the strike: (premium + strike - basis) / basis. It is what you earn if the shares are assigned. If-called is larger whenever the strike sits above your basis, but it is a one-time outcome that closes the position, so annualizing it is the more misleading of the two numbers.
