Can we still FIRE with the ever rising costs?

Ok so I genuinely have a question whether that FIRE number ( 25 x your annual expenses) really still holds in the current situation in the UK? For instance, I went on a holiday for a couple of weeks and when I got back there had been a 3-4% increase in the price eggs, water etc. And that over-inflation TFL rise next year… Honestly I just don’t have the confidence I’ll ever get there anymore!
