How many days to expiration (DTE) for a cash-secured put?
There is no single correct DTE for a cash-secured put. A shorter-dated put collects less premium per contract, but loses its time value faster each day and has to be re-established more often to keep a position on. A longer-dated put collects more premium in dollars, but less per day, and ties up the cash that secures it for longer. Which expirations someone uses is a choice about that trade-off, not a rule.
What DTE means
Days to expiration (DTE) is the number of calendar days from today until the option expires. For a cash-secured put it sets three things: how long the cash securing the put (the strike × 100 per contract) stays committed, how much time value the premium contains, and which scheduled events, such as an earnings report, fall before expiration.
How time decay changes with DTE
An option’s time value does not decay in a straight line. The Options Industry Council describes theta, the daily time decay, as gradual at first and accelerating as expiration approaches; in its worked example, time premium starts to fall quickly around 30 days before expiration. For a put seller, a shorter-dated contract therefore loses more of its remaining value each day, while a longer-dated contract holds more total premium that decays more slowly. Near expiration, an option close to its strike also becomes very sensitive to each move in the stock: its delta can swing between near zero and near one within days.
Annualized yield favours short dates, on paper
Annualized yield divides the premium by the strike and scales it by 365 ÷ DTE. A hypothetical $0.50 premium on a $50 strike at 7 DTE is a 1% static return, which annualizes to about 52%; a hypothetical $1.50 premium on the same strike at 45 DTE is 3% static, about 24% annualized. The shorter contract’s larger figure is arithmetic: it assumes the same premium could be collected again and again for a year, which nothing guarantees. Annualized yield is premium arithmetic, not an expected return.
Shorter vs longer DTE, side by side
A descriptive comparison of two puts on the same stock at a similar delta. It shows what changes with the expiration, not which one is better.
| Shorter DTE | Longer DTE | |
|---|---|---|
| Premium per contract | Smaller | Larger |
| Time value lost per day | Faster, especially in the final weeks | Slower |
| Annualized yield (premium arithmetic) | Tends to be higher | Tends to be lower |
| How often a position is re-established | More often: more orders, more bid–ask spreads paid | Less often |
| Sensitivity to a sharp move near the strike | Higher close to expiration | Lower |
| Range of possible prices by expiration | Narrower | Wider |
| Chance an earnings report falls before expiration | Lower | Higher |
| Cash committed | For a shorter time | For a longer time |
Why there is no single right DTE
Many stocks list options with weekly as well as monthly expirations, and options education describes several windows as conventions. Each window is a choice of how much premium per contract, how much time decay per day, how many re-entries and how much event exposure. None of them removes the core risk of a cash-secured put: owning the shares at the strike if the stock falls below it.
How PutFinder shows DTE
PutFinder’s daily screen compares contracts inside one expiration window, so every ranked contract is on a comparable time footing: too close to expiration leaves little premium and a lot of noise, and too far out ties up capital for longer than contracts can be compared fairly. Each contract shows its DTE next to its annualized yield (premium ÷ strike × 365 ÷ DTE), delta and downside buffer. An earnings report before expiration is checked: the closer the report sits to expiration, the more cautiously the contract is treated, and some are left out. The per-ticker analysis ranks one stock’s contracts across every expiration in the window. The cash-secured put calculator recomputes the annualized figure for any DTE you enter. The screening steps are on the cash-secured put screener page, the terms are in the beginner’s guide, and how past daily picks resolved is on the performance page.

Common questions
What is the best DTE for selling cash-secured puts?
There is no DTE that is best for everyone. Shorter expirations lose time value faster per day but collect less per contract and need re-establishing more often; longer expirations collect more premium but less per day, tie up cash for longer and are more likely to include an earnings report. The windows quoted in options education are conventions on that trade-off. Descriptive, not investment advice.
Why does a weekly put show a higher annualized yield?
Because annualizing multiplies a short contract’s return by a larger factor (365 ÷ DTE). The figure assumes the same premium could be collected again and again for a year, which is not guaranteed. Annualized yield is premium arithmetic, not an expected return.
Does time decay speed up near expiration?
Yes. Time decay is not linear: the Options Industry Council describes it as gradual at first and accelerating as expiration approaches. Near expiration, an option close to its strike also becomes very sensitive to each move in the stock.
Can a cash-secured put be assigned before expiration?
Yes. Most US stock options are American-style, so the buyer can exercise at any time before expiration and a short put can be assigned early, most often when it is deep in the money. A longer DTE leaves more days in which that can happen.
