## Professional career

After turning professional, Calderón was frequently showcased on ESPN's Friday Night Fights show. On July 1, 2001, Calderón defeated José Manuel Ramírez by unanimous decision. During this fight, he suffered an open wound over his right eyebrow, which required surgery. On May 3, 2003, Calderón became a world champion for the first time, defeating Eduardo Marquez by a technical decision in nine rounds at Las Vegas, as part of the de la Hoya-Campas undercard, to win the World Boxing Organization's world strawweight title. He had dropped Marquez twice before the end of the fight. Calderón retained his title by a 12-round decision in his first defense, on September 5, over Lorenzo Trejo of Mexico, at Caguas, Puerto Rico. In his second defense, held at Bayamón, he defeated former world champion Alex Sanchez by a unanimous twelve-round decision. On March 20, 2004, he retained the championship with an eleventh-round knockout win over former International Boxing Federation world champion Edgar Cardenas, in Guaynabo. Before that fight, Calderón obtained his high school credit diploma.
On July 31, 2004, as part of the Morales-Hernandez undercard in Las Vegas, he retained his title once again, with a twelve-round decision win over former world champion Roberto Leyva. On November 23 of that year, he made his fifth defense, defeating Nicaraguan Carlos Fajardo by a twelve-round unanimous decision. As part of the Barrera-Morales III undercard.

On September 25, he retained his title for the seventh time, with a twelve-round unanimous decision over Mexico's Gerardo Verde, at Atlantic City, New Jersey.
On December 10, 2004, Calderón retained the title again, this time with a twelve-round unanimous decision over former world champion Daniel Reyes. Calderón began 2006 by defending his title successfully on February 18, with a twelve-round unanimous decision over Isaac Bustos in Las Vegas. He would defend his title successfully twice in 2006 after his fight with Isaac Bustos. On April 29 against Miguel Tellez winning the fight by technical knock out thus gaining his sixth knock out victory. He finished his boxing year on October 21 by defeating José Luis Varela of Venezuela by unanimous decision. Following this fight the World Boxing Organization recognized him as a WBO Super Champion for reaching ten successful title defenses. On his first fight of 2007 that took place on March 28 in Barranquilla, Colombia Calderón defeated Ronald Barrera by split decision. Following his fight against Barrera Calderón announced that he was interested in changing weight and challenge one of the champions in the light flyweight division thus finishing his minimum weight run after twelve successful defenses of the division's title.
During this timeframe, Freddie Roach selected Calderón as a sparring partner for Oscar De La Hoya. The reason for this was that the trainer was seeking a fast adversary. On November 16, 2008, Roach rememorated the event in his blog for The Ring, stating that "Calderon slapped Oscar around like it was unbelievable." The trainer also noted that he asked De La Hoya to pursue the offense, but the boxer's attempts were unsuccessful. In response, Calderón expressed that he participated in "three or four rounds" of sparring, during which he "gave him problems" and "made him uncomfortable", while De La Hoya "tried to hit" but seemed "out of timing". Similarly, Calderón competed against Shane Mosley in a four-round sparring match. The session was in preparation, serving as training for the first of a series of fights against Hugo Cázares. During the actual contest, Mosley had problems landing punches due to his adversary's speed. While Calderón recognized that his opponent's weight made the practice feel like a complete workout. Subsequently, Mosley expressed that "Iván uses the angles very well and sparring against someone that moves so much is fun". Calderón noted that competing against a heavier boxer helped him adjust to the pressure that could be presented by Cázares.

### Light flyweight division

On August 25, 2007, Calderón defeated Hugo Cázares by split decision to become the WBO and Lineal Light Flyweight Champion. Calderón entered the ring accompanied by a display of fireworks, before a crowd that featured several media personalities, including Oscar De La Hoya. The size difference between both pugilists was evident since the moment that they stood next to each other prior to the beginning of the fight. Early in the fight Calderón's tactic consisted of connecting fast consecutive combinations while avoiding Cázares' punches. With this strategy he managed to stun Cazares with uppercuts and straight punches. During the fight the crowd displayed support for Calderón, at one point chanting "Olé" when his adversary's punches missed. In the third round Cázares displayed a more fluid offensive, but in the fifth he presented a strategy that consisted of only throwing power punches which seemed to benefit Calderón. In the seventh round Ivan's offensive pace slowed which benefited Hugo who improved on the offensive aspect. In the eighth round Cázares connected several hard punches which led to Calderón to rely on holds to slow his offense, in this round Cázares scored a knockdown. In the ninth he was in a defensive stance, and during the last rounds he continued this pattern and only connected solidly in the tenth round while Cázares missed several of the punches he threw. At the conclusion of the fight the judges awarded scores of 116-111 for Cázares and 115-112 twice for Calderón. With this victory he became the eleventh Puerto Rican boxer to win multiple world championships and unified this championship with the minimum division's one until he vacated it following the announcement that he was going to continue in the light flyweight division. The Ring also recognized Calderón as their champion, dethroning Cázares.
Calderón was successful on his first light flyweight title defense when he defeated Juan Esquer in a card that took place on December 1, 2007, in New Mexico. During the course of the fight Esquer was more active offensively. During the first four rounds of the match Calderón used his boxing skills to avoid being hit by the punches thrown by Esquer. From the fifth round onwards Calderón proceeded to exchange combinations of punches with Esquer, eventually gaining control of the fight's tempo. The fight lasted twelve rounds and Iván won the fight by unanimous decision with the judges awarding scores of 116–112, 118-110 and 115–113. Calderón's second defense in the light flyweight division took place on April 4, 2008, where he defeated Nelson Dieppa by unanimous decision. The three judges awarded him identical scores of 120–108.
Following a protest, the World Boxing Organization named Cázares the mandatory challenger for the championship. The event was scheduled for August 30, 2008. Calderón entered the ring dressed as a matador in reference to his boxing style, which provoked "Olé" chants from the public. In the early stages, the fight's pattern was similar to the first meeting. Calderón relied on counter punching while boxing to avoid Cázares' offensive. Late in the first round, the challenger fell following a combination, but the referee declared that it was an accidental slip. In the following rounds, Cázares tried pressuring in the offensive, but Calderón continued boxing and held his opponent if approached. The challenger was momentarily stunned by an uppercut in the final seconds of the third episode. Cázares' technique in the next two rounds consisted of throwing punches to the body, while his offensive to the head was being stopped by his opponent's forearms. In the sixth round, Calderón focused on his defense, slowing the pace of his offensive. In the seventh episode, an accidental head clash opened a laceration in Calderón's forehead. Who was examined by the ringside doctor, after expressing that he was feeling disoriented. The physician recommended stopping the fight. Due to the circumstances, the outcome was decided by the judges' score cards, which favored Calderón 67-66 and 68-65 twice. Following the event, he announced his intention to participate in a unification match against one of the other light flyweight champions. Due to the nature of this injury, the Puerto Rico Boxing Commission prohibited Calderón participation in any card within 120 days. Two weeks after the contest, the wound was reopened and he underwent plastic surgery to prevent reinjury. On September 23, 2008, Peter Rivera announced that Calderón was expected to return between January and February 2009. Rivera noted that the fight would be against one of the other light flyweight champions, most likely César Canchila, citing that although both Ulises Solís and Edgar Sosa were approached, with both claiming to be available, neither one actually pursued serious negotiations. He subsequently stated that negotiations had been extended to Solís' representatives, but that those of Sosa still declined, citing that "[He] is a fighter that has always refused to fight with Iván. His managers don't want to sacrifice him and prefer to keep him in Mexico competing in soft fights." In the meanwhile, he received a homage as part of the Dominican Parade in San Juan, serving as Padrino Internacional (lit. "International Godfather") along Juan Manuel López.
On June 13, 2009, Calderón defended the championship against Rodel Mayol. During the first stage, both pugilists fought in the middle of the ring, while he focused on attacking the body while the challenger employed jabs. During the second and third rounds, Mayol pressured the offensive, managing to land a moderate number of punches. In the fourth round, Calderón began pursuing the offensive, while avoiding Mayol's punches. This continued in the following chapter, but a head clash opened another laceration on his forehead, he continued the contest, but was more aggressive from this point onwards. Calderón's corner tried to stop the bleeding, but the referee suspended the contest during the sixth round after these attempts proven unsuccessful. The fight was declared a technical draw, with both fighters receiving a 58-56 card while the third judge scored in 57-57. An immediate rematch was scheduled three months later. Calderón began this contest by effectively avoiding Mayol's constant attack, while throwing limited punches. This pattern continued during the following three rounds. In the fifth, Mayol connected his best punch of the fight, winning the round. To retaliate, Calderón became more aggressive, throwing more combinations. The seventh round began with exchanges from both boxers, but a head clash opens another laceration that stops the fight. The contest was declared a technical decision, with the judges offering scores of 68-65 twice for Calderón and 68-65 for Mayol.

## Retirement

On October 29, 2012, almost a month after his last fight, Calderón officially announced his retirement from professional boxing. The announcement was made during the inauguration of the Félix Pagán Pintor Gymnasium in Guaynabo, Puerto Rico. Calderón will now work as administrator of the gymnasium.
