The Magpies have struggled to agree on more deals since signing Kieran Trippier and Chris Wood earlier this month.
Negotiations have not gone according to plan, with clubs raising their financial demands for players Newcastle have been targeting in the ongoing transfer window.
Newcastle are hopeful of adding more players by 31st January but they have found the going tough and Howe conceded that ideally, he would have wanted to sign more players.
The Newcastle boss stressed if they do not add more players to the squad he would have to believe that he still has enough to save the club from getting relegated this season.
He insisted that Newcastle are working tirelessly behind the scenes to bring in more players but finding the right name at the right price, who wants to join the club, is extremely tricky in the winter window.
Asked if he would be happy if Newcastle do not sign anyone until the end of the window, Howe told talkSPORT: “I think from my perspective now, ideally we would like to bring in more.
“But if it is the two, it is the two. There is not a lot anyone can do about it if you can’t get the deals over the line that you are seeking to do.
“We have to deal with facts and reality and if that was the case, we would be looking forward with the squad and believe that we have enough to stay in the division.
“But ideally I think we are looking to do more business in January. I have said this all throughout the month.
“People at the club are working tirelessly and everyone in those departments are actively seeking players who can make a difference and keep us in the division.
“That’s the key – it’s about finding players who can make a difference, that are attainable and want to come and that combination is not easy in January.”
Newcastle are now reportedly prepared to throw the kitchen sink at Jesse Lingard in order to try and sign him from Manchester United this month.
