Huw Jenkins told The Footballers' Football Show that Swansea are desperate to stay in the Premier League - but not at all costs.
The Welsh outfit are currently enjoying their second season back in the top flight and after finishing 11th under Brendan Rodgers last term, are now entrenched in the top 10 under new boss Michael Laudrup.
But Swans chairman Jenkins says he will not instil a free-spending culture at the Liberty Stadium in the hope of remaining in the elite division.
And he also urged clubs to ensure they are not burdened by hefty player wages if they do sink into the Championship.
"We are all out to remain part of the Premier League but there has to be a realism and you have to watch that you don't do it at all costs," said Jenkins.
"We try to run our football club so that there is no pressure on anybody and will do our best to strengthen in January and give Michael (Laudrup) and the squad a chance to push on.
"But it's all done within a level that we can afford; we won't take financial risks to keep the club in the Premier League.
"We have a system at our club where players get a pay cut if we get relegated and I think that acts as a fantastic motivational tool; if someone knows they are going to get a 30-40 per cent pay cut, you'd think they may try harder to stay up!
"I think that should be introduced into every player's contract in the Premier League."
Stoke chief-executive Tony Scholes says his club, who have finished no lower than 14th since they were promoted to the Premier League at the end of the 2007-08 campaign, plan for the worst every season as they look to safeguard the Potters' future.
But he does expect some of the teams currently locked in the relegation dogfight to loosen their purse strings in January - even though they may not get great value for money.
"The Premier League is tough to get into and once you're there your primary objective is to stay there - and with the new TV deal coming in, it is your primary objective and then some," said Scholes.
"You can't risk everything and you have to have one eye on 'what if?'. You don't want to contemplate it but you have to make sure that if you are relegated you are still sustainable and strong enough to launch a campaign to get back up.
"If a club is run properly, all scenarios are covered."
Scholes added: "The January window is a difficult one, so you have to look at your squad and decide by looking at the market what the right thing to do is.
"January tends to be more expensive so the clubs that tend to buy are the ones that need to buy - the ones that see an opportunity to lift up or a need to avoid a drop down - rather than are strategically planning to buy. Most clubs would choose to buy in the summer."
