Calculating UK inflation and transfer values

I'm figuring the UK CPI inflation from 1996 to 2025, estimating around 2% per year. If I multiply that out, from 1996 to 2024, it gives an increase of about 1.9x, meaning £15 million could inflate to around £30 million. But £225 million isn't just about consumer inflation; it's about football transfer inflation owing to TV revenue growth. I think I can do a sanity check using TPI index values or calculating record fees for context.Providing concise response context

I think we should respond with some clear context and ask what the user would like next. I'll create a concise bullet list:

• Fact: Shearer’s 1996 fee was £15 million, a world record.
• Adjusted for CPI, that’s around £30-35 million today, indicating a football market inflation factor of about 15x.
• Possible index to consider could be CIES or TPI, as the Premier League average fee has grown 12-18x since the mid-90s, with top-of-the-market fees even higher.
• I need to mention caveats like exchange rate, nominal vs. real values, and the Bosman ruling in 1995.

If they want, I can quickly replicate this with a simple model based on Premier League revenue growth.
