The 61-year-old former Chelsea coach's contract expires at the end of the tournament in Gabon.
"I came for two years in Ghana, we extended to two years and three months because we qualified for the Nations Cup," Grant told BBC Sport.
"I will always take good memories from here, but hopefully the last memory will be the best one."
Leading Ghana to the title in Gabon, and ending the Black Stars' 35-year wait to win the Nations Cup for a fifth time, would be a sensational way for Grant to sign off.
And it would help to ease the pain of losing on penalties to Ivory Coast in the final two years ago.
Grant's side are on track in Gabon and will book a quarter-finals place if they beat Mali in their second Group D match on Saturday, having defeated Uganda 1-0 in their opener.
Regardless of whether Ghana go all the way or contrive to fail to qualify from their group, Grant's comments appear to confirm he will soon be employed elsewhere.
Grant has been linked with job offers from China and Australia, but when asked what his next move will be Grant was non-committal.
He said: "I am happy with what I have achieved in my career.  In my life I never plan. What will happen, will happen. Let's see.
"I am looking forward myself to see what will happen."
Avram Grant has given a strong indication his time as Ghana coach will end after the Africa Cup of Nations.

Little, 17, is replaced by fellow seamer Peter Chase, who is now in line to make his T20 debut for his country.
"There were concerns about the time missed in what is a crucial period for Josh's education," said Ireland coach John Bracewell.
Chase, 23, has played eight one-day internationals for the Irish.
"Peter gives us cover in the bowling department and we'll also have Niall O'Brien and Ed Joyce on stand-by for the T20 series as they'll be in India preparing for the ODI and Intercontinental Cup games which follow," continued Bracewell.
"Peter was impressive during the ODI series last summer against Afghanistan taking seven wickets and gets that crucial extra bounce with his height."
Meanwhile, former Leicestershire coach Ben Smith will act as a consultant assistant coach for Ireland's games in the United Arab Emirates and India.
The 44-year-old, who has also held coaching roles with Worcestershire and the ECB Development Squad, is currently working in New Zealand as a specialist coach with Central Districts.
"Andrew White did an excellent job during the Desert T20 but was unavailable for the tour due to work commitments," Bracewell said.
"Ben has impeccable credentials and I'm sure will bring valuable experience and knowledge to the Irish camp during the tour."
Ireland face the UAE in one-day games in Dubai on 2 and 4 March before travelling to India to face Afghanistan in nine matches across three different formats over the following four weeks.

Josh Little has been forced to pull out of Ireland's squad for next month's T20 series against Afghanistan because of school commitments.

Fans held a minute's applause on 11 minutes to mark next Sunday's fifth anniversary of the death of Gary Speed, who played for both clubs.
Dwight Gayle pounced on a Rob Green goalkeeping error to volley home.
Leeds rallied and saw Eunan O'Kane's shot well saved but Gayle's second, from a sharp team move, sealed Newcastle's eighth win in a row.
Defeat ends Leeds' three-game winning run and leaves them just outside the play-off places.
In front of a sell-out 36,000 Elland Road crowd, these two old heavyweights evoked memories of happier top tier times with a first league meeting since 2004.
The tribute to Speed brought the two teams together briefly before a match that Newcastle controlled for the most part.
Gayle's breakthrough goal came from a swinging Jack Colback cross-shot that Green failed to cope with, the first real opportunity of the game.
The goal ignited a response from Leeds as referee Graham Scott waved away Pontus Jansson's protests for a penalty at the end of the half, and they continued that momentum early in the second period with possession and some pressure.
Yet Newcastle snuffed out the home side's hopes of snatching a point or more when sharp passing sliced open Leeds' left and Gayle turned in Vurnon Anita's cross for a second.
Leeds United boss Garry Monk told BBC Radio Leeds:
"We fell the wrong side of the critical moments, they started well in the first 20 minutes but even then we defended well and we gave them goal but after that we reacted really well.
"It was a clear cut penalty, if that goes in and we get that decision it changes the dynamic of the game and through some of the chances we just needed a goal.
"We have to respect we're playing a good side, it's alright going gung ho but we have to be smart, I thought we got to grips with it and all in all we were competitive again."
Newcastle United manager Rafael Benitez told BBC Newcastle:
"I have to say thanks to every player, we could see a performance today against a good team we saw the effort, the mentality was good and the understanding of the game was very good.
"The atmosphere we were talking about as intimidating but we controlled ourselves. We knew what they could do but the players applied themselves and it's a credit to them.
"Everything we tried to do we did well, set-pieces, control of the game and counter-attack. There is room for improvement but I can't complain because we did very well."
