Aston Villa gambled £143m in transfer fees to avoid being relegated following their promotion and their 35 points meant each precious point cost over £4m.
Meanwhile, United's cost-per-point was almost £3m as they spent big in summer and again on Bruno Fernandes in January to avoid another season without Champions League football.
Liverpool did the bulk of their transfers in the last couple of seasons and each one of their 99 points on the way to winning the title cost them just under £95,000. Chelsea, Crystal Palace and Burnley performed well on a low transfer budget, as did Southampton and Sheffield United.
A BonusCodeBets spokesperson said: "Manchester United's deep pockets just about got them over the line to finish in the Champions League in a season where big-spending didn't always result in a big points return.
"Liverpool put the work in the transfer market in previous seasons, while Crystal Palace, Burnley, Southampton and Sheffield United performed well on a tight budget."
