Updated March 1, 2025 · ONS / FRED
£100 in 2020 is worth £125.67 in today's pounds, adjusted by British consumer-price inflation (UK CPI), which rose 26% since then. ONS / FRED data through March 1, 2025.
In 2020, £100 was a routine sum, just before pandemic stimulus, supply-chain disruption and energy costs pushed UK inflation to roughly its highest in four decades by late 2022. The price surge that followed was sharp and recent. Even over this short span, matching what the amount could buy then now takes a noticeably higher figure in today's pounds.
UK CPI before 1997 splices the historical retail-price record. Values are in pounds sterling, continuous since the 1971 decimalisation. This tracks consumer-price inflation, not exchange rates or investment returns.
