Norwich's play-off final win has earned them at least £80m - and that could more than double if they stay up in the Premier League next season.
Even if Norwich were relegated in 2015/16 they would still receive prize money and TV revenue, plus £24m, £19.2m, and £9.6m in the following three campaigns in parachute payments.
With a new broadcast deal coming into place in 2016/17, if Norwich can stay up they could earn at least £180m.
Because Norwich are entitled to parachute payments from their relegation from the Premier League in 2013/14, their totals are actually lower than what Middlesbrough would have stood to earn.
Promotion for Boro would have been worth £130m and £230m if they'd stayed up next season.
Championship winners Bournemouth and runners-up Watford can also expect a revenue increase of at least £130m. This is a combination of the extra income they will earn from playing in the Premier League in 2015/16 and parachute payments should they be relegated after one season.
Deloitte financial expert Adam Bull said: "Although the clubs promoted last season fought a relegation battle, in each of the last six seasons at least two of the three promoted clubs have successfully retained their Premier League status in that crucial first season.
"The continued increase in the value of promotion to the Premier League provides newly promoted clubs the opportunity to make strategic investment on and off the pitch.
"Inevitably, the short-term priority is usually investment in the playing side of the business, but clubs should also look to make improvements for the medium and long term."
