Captain America’s MCU tale ranks among the finest, partly due to the fact that the First Avenger doesn’t experience a typical lifespan. Early on, Steve Rogers (portrayed by Chris Evans) receives a super soldier serum which boosts his resolve to “do this all day” with enhanced strength. This leads to decades of protecting the vulnerable, culminating in “Avengers: Endgame” where he bequeaths his shield to Sam Wilson (Anthony Mackie). At this juncture — when Steve is aged, content, and has wrinkles — he is 180 years old.

Naturally, the next logical question arises: how did we arrive at this number? The explanation is, as you might guess with this character, quite complex. It involves natural cryogenics, time-travel for saving universes, and exceptional longevity. Before we delve too deep into the intricacies, let’s begin from the start.

Steve Rogers was born on July 4, 1918. This is evidenced by his enlistment paperwork, indicating he is in his mid-twenties when officially inducted into the U.S. military. At that stage, he’s merely a regular guy, riddled with health problems, poised to live an ordinary life — if he survives the war. Then he receives the serum, becomes a national icon, and confronts Red Skull (Hugo Weaving) in a battle that seems to involve him making the ultimate sacrifice.

Steve Rogers is around 26 years old when he crash-lands in the Atlantic at the end of his first solo movie. His body effectively “goes on ice” for another 66 years, until he awakens in 2011. He joins the Avengers shortly afterward and spends the next seven years building up to the big showdown with Thanos (which happens to coincide with his 100th birthday). That drags on for another half-decade, which means Cap is 105 years old when he travels back in time and finally gets that dance with Peggy Carter (Hayley Atwell).

But his story isn’t done at that point. It also gets a tad confusing, since we don’t know when he landed back in time. Our only clue comes from the show “Agent Carter,” which follows Peggy’s adventures after “Captain America: The First Avenger.” It spans 1946 to 1947, with Cap missing during that entire time, so we know Steve doesn’t go straight back to 1945 for his dance. One explanation suggests 1948 as a reasonable year for Cap to show up again from the future.

Despite already being technically over a century old, he’s really only aged 12 years from his first movie (in non-frozen time). For Peggy, the timeline is even shorter: in 1948, it’s been a short three years since he went into the ice. This is where the super-soldier serum effect clearly kicks in, as Cap goes on living for another 75 years before we see him again in 2023. His age at that point? A ripe 180 years old.

While old Cap is around 180 years old at the close of “Endgame,” that number is a bit misleading. If we can assume that he didn’t really age when he was “on ice,” we need to subtract 66 years from his official “age.” This puts him, via natural aging, at 114 years old during “Endgame,” and he still certainly looks spry for that age.

The other factor to consider is: when is Steve going to die? Is he already dead in the current timeline? He’s clearly aged despite the serum, and it does seem possible that Cap has already shuffled off this mortal coil. By the time he hangs up the shield, it’s been several years since Peggy Carter passed away in 2016 (in “Captain America: Civil War”). Perhaps Steve let go of his unnaturally long life (like Aragorn in “The Lord of the Rings”) after losing his love and passing on his superhero identity. If that’s the case, we can’t calculate a total lifespan until we get some kind of clarity on his death date.

There is no official declaration of Steve Rogers’ death as of this writing, so there’s a chance he’ll pop up at some future date — or at the least, we’ll get closure of some kind in “Avengers: Doomsday” or another upcoming movie. If he’s still kicking around somewhere, that would mean he’s a robust 186 years old by the events of “Captain America: Brave New World” — or 120 via normal aging in non-frozen years. Either way, it’s yet another impressive accomplishment on the First Avenger’s resplendent resume.
