The Glovers earned promotion to the second tier for the first time with a 2-1 play-off final win over Brentford at Wembley on Sunday and are already favourites to return to League One in 12 months' time.
Despite the huge increase in income, Starnes says they will not gamble the club's future and will have to upset the odds once more.
"It's going to be difficult because we'll be the smallest club in the Championship," he told the Western Daily Press.
"But we've been the underdog in League One for many years - we've always overcome those odds, so we'll have a go next season and see what happens.
"We didn't want to count our chickens but we have done a certain amount of preparation for whether we would be in League One or the Championship next season.
"It's well known in football that Yeovil have to work within our resources. We've done that for several years and sustained our place in League One."
