DH and I earn about £25k jointly, we save for £100 per month each for house repairs/improvements (and other yearly expenses i.e road tax), xmas and holiday (xmas not extravagant and holiday is always UK and as cheap as I can get it). We've just started saving £200 per month for an emergency fund (now that DS has finished nursery!!) which can then be used to buy another chunk of our shared ownership house if the money hasn't been used.
Currently 'own' 25% of our house (mortgaged) (we did this so we could move into the area we wanted), HA own the remaining 75%. We also have £10k savings but this is only the equity from the last house we sold and will be used to install new bathroom and kitchen etc.
No debt apart from small outstanding amount on credit card. No other debts and I would say we are reasonably frugal but we do have takeaways, go to cinema every so often, have cable tv, nice clothes and shoes for kids etc but no fancy gym memberships, kids clubs/activities, rarely drink, don't smoke, don't spend a lot on xmas and birthdays, don't spend a lot on electrical stuff (tv's, phones, laptops - always cheap/second hand) etc. We are 30 and 37yo.
We're not brilliant at saving, there's always something needed that seems to pop up but we're going to try our best with this as our jobs aren't as secure as they have previously been and it feels good to try have something there for peace of mind even if it's not a lot by most people's standards.
