A LEAPS costs more upfront and decays slower per day. That trade-off is the whole strategy.
LEAPS — options with a year or more left until expiration — aren't a different kind of option, just a much longer-dated one. That extra time changes the price you pay today and the pace you lose it at, which is why traders reach for LEAPS in different situations than a standard monthly option.
Same option, far more time
A LEAPS option isn't priced by a different formula — it uses the same five Black-Scholes inputs (spot price, strike, time to expiration, a risk-free rate, and implied volatility) explained in the Black-Scholes pricing guide. The only input that's unusual is time: a LEAPS typically runs one to three years, instead of the days-to-months most listed options carry.
Holding every other input fixed, a $90 strike call on a $100 stock priced 30 days out costs $10.70 with a delta of 0.90. The same $90 strike priced a full year out costs $19.15 — nearly double — but its delta is 0.74 and its per-day theta is roughly 0.019, compared to about 0.033 per day for the 30-day option. You pay more up front for a LEAPS, but each individual day costs you less in time decay, because that larger premium is amortized over hundreds of days instead of dozens.
Where the theta trade-off comes from
The Greeks 101 guide covers theta and vega in general; LEAPS are the clearest illustration of both at once. Time decay isn't linear — it accelerates as expiration approaches, so an option with a year left loses value from the passage of time far more slowly, day by day, than one with weeks left. That's the lower theta. But the same extra time also raises vega: a long-dated option's price reacts more to a change in implied volatility than a short-dated one does, because there's more time left for that volatility to actually matter to the outcome. In the example above, the 30-day call's vega is about 0.05 per volatility point; the one-year LEAPS is closer to 0.33 — roughly six times as sensitive. A LEAPS position that looks stable on theta can still move a lot if implied volatility itself shifts.
Three ways traders use LEAPS
Stock replacement. A deep in-the-money LEAPS call — one with a strike well below the current price — carries a delta close to 1, meaning it moves nearly dollar-for-dollar with the stock. A one-year, $70-strike call on a $100 stock at the same assumptions above prices at $33.80 with a delta of 0.93: roughly a third of the capital of buying 100 shares outright, for most of the same near-term price sensitivity. It isn't identical to owning the stock — it still expires, and it's exposed to vega the stock isn't — but it's the closest options-based approximation to it.
The poor man's covered call. A standard covered call needs 100 shares as collateral for the short call. A poor man's covered call substitutes the deep in-the-money LEAPS above for those shares, then sells a shorter-dated, out-of-the-money call against it for income — the same short-call leg as a regular covered call, at a fraction of the capital. Continuing the example: the $33.80 LEAPS call paired with a 30-day, $105-strike short call (priced at $1.66, delta 0.31) collects that $1.66 in premium against a much smaller capital base than owning shares would require. The trade-off is that the short call must be managed and re-sold as it expires, and the position can still lose money if the stock falls enough that the LEAPS itself loses value faster than the short calls collect premium.
A longer-duration directional bet. Some theses just take longer than a month to play out — a multi-quarter product cycle, a slow re-rating, a long-horizon macro view. A LEAPS lets a trader take a directional position sized to that timeline without needing to be right about short-term timing, and without paying the accelerated decay a short-dated option would carry across the same holding period. The cost is the larger upfront premium and the vega exposure described above.
What the trade-off doesn't remove
A lower theta is not the same as no risk. The full premium paid for a LEAPS call is still at risk if the underlying thesis is wrong, and because LEAPS carry meaningfully more vega than short-dated options, a drop in implied volatility can erode a LEAPS position's value even while the stock itself is flat or modestly higher. None of the three strategies above remove that; they change which risk you're most exposed to, not whether risk exists.

Frequently asked questions
What does LEAPS stand for?
Long-term Equity Anticipation Securities. Mechanically a LEAPS option is identical to any other listed option — same strike, same exercise rules — the only difference is that it has a year or more remaining until expiration, rather than the weeks or months most listed options run for.
How is a LEAPS option different from a regular option?
Nothing about the pricing model changes — the same Black-Scholes inputs (spot, strike, time, rate, volatility) apply either way. What changes is the balance those inputs strike: more time raises the premium you pay today, but spreads whatever daily time decay exists over far more days, so the decay per day is smaller even though the total premium at risk is larger.
What is a poor man's covered call?
A diagonal spread that swaps the 100 shares in a standard covered call for a single deep-in-the-money LEAPS call. You still sell a shorter-dated call against the position for income, but the capital required is the LEAPS call's premium instead of the full cost of 100 shares — a large reduction, though the position isn't a perfect substitute for owning the stock (see the next question).
Why do LEAPS have lower theta but higher vega than short-dated options?
Time decay accelerates as expiration approaches, so a option with a year left loses value from time far more slowly, day to day, than one with weeks left — that's the lower theta. But a long-dated option's price is also more sensitive to a change in implied volatility, because there's more time left for that volatility to matter — that's the higher vega. The two effects move in opposite directions as expiration lengthens.
Is a LEAPS call a substitute for buying the stock?
Only a partial one. A deep in-the-money LEAPS call can move close to dollar-for-dollar with the stock (a delta near 0.90+), for a fraction of the capital that buying shares outright would require. But it isn't identical: the position still expires, it carries vega exposure the stock doesn't have, and it can lose money even if the stock is flat or only modestly higher, if implied volatility falls enough before expiration.
