Charlton manager Phil Parkinson believes his team will need at least 23 points from their 12 remaining matches to reach safety in the Coca-Cola Championship.
Parkinson is hopeful that 50 points would keep the Addicks up, however his bottom-placed side could only manage a 1-1 draw at Swansea to leave them with a tally of 27 and everything to do to preserve their status in the second tier.
"It was a great show from the players and after we equalised we even went looking for the winner," said Parkinson. "This team has shown signs that they are capable of going on a run and will have to keep this level of performance up."
He added: "We have good players and have now gone three games unbeaten and the players are now beginning to show a belief in themselves.
"We probably need at least 50 points for safety but we will take each match as it comes and see where that takes us."
Nathan Dyer gave the home side a 41st-minute lead, but the visitors levelled 10 minutes after the break when Nicky Bailey's shot was deflected into the net.
Charlton had five players booked in the game, but Parkinson said: "Swansea's players over-reacted to a lot of challenges and the referee never showed us any favours but we didn't deserve so many bookings."
