I know it should be 3x the committed monthly outgoings (some even say it should be 3x monthly income) but there's genuinely no way we can save that much for the foreseeable future. Our current committed spending including repayments is of £4200 (or there abouts). We're thinking of then having £400 left for emergencies, £300 for unaccounted bills or top ops, and £500 for going out/general spending. Once we pay the credit cards (Apr 23), we'll be in a much better position of having other pots for Xmas, personal care, car fund, and holidays.
