The 36-year-old midfielder has played sparingly for United this season, after a heart scare earlier this season.
Internationally, he represented England thirty-four times and was part of the squads for the World Cup finals in both 2006 and 2010.
The former England worldwide, 36, made the announcement at United's press conference on Monday to preview the Champions League last 16, second leg against Sevilla.
"I think it's pretty much already been said, to be honest with you", he replied when asked whether he was retiring.
Carrick, capped 34 times by England, has looked likely to leave United in recent summers only to pen extensions at a club that rewarded his fine service with a testimonial a year ago.
Carrick added: "All the glitz and the glamour that can surround things these days, Scott doesn't seem too interested in that, which is fantastic - especially at this stage of his career".

"There comes a time when as much as you don't like, it's time to stop playing football", Carrick confirmed, quoted by the Press Association's Simon Peach.
United last hosted a Champions League knockout game in 2014 and skipper Carrick says it is high time they competed again for European football's top trophy.
"I had a problem in the Burton game it started in the second half, had a few tests and the same problem came back on the Sunday of that week".
'I got back fit and I wanted to finish on my own terms really.
"So, I was determined to get back fit. I am trying to help a lot more because I understand where I am at". Carrick made just one Premier League appearance this season and saw Nemanja Matic partner Ander Herrera and lately Scott Mctominay as his replacements in the United midfield. "I've been training hard and we'll see what happens for the rest of the season", said Carrick.
"Hopefully I can get some game-time at some point between now and the end of the season", he said.
