It sounds too obvious, but you are obviously spending beyond your means somewhere.
We are typically probably about £100k combined, but I had to leave work due to cancer, so while Dh is the higher earner, we’ve lost my salary for the past year. So we’re at maybe £70k now (Dh self employed so no set salary). I definitely would say we’re quite comfortable and not pressured at all.
Our mortgage is £1700 pcm, but we overpay some on occasion. We have 2 dc with all their activities. Also have a dog. We both have expensive hobbies, Dh cycles and I have a horse who I pay livery on. We go on holidays, not ridiculous ones, but 2 weeks camping in France last year, I went to Spain solo this year, family holiday to Wales this summer. We may take the camper van to Spain next year. I shop at Tesco and Waitrose.
What we don’t have is lots of little luxury expenses. Don’t buy a coffee on the way to work or a meal deal for lunch. We bring coffee in a flask and a packed lunch. We don’t eat out or get takeaways, maybe for someone’s birthday only. No nights at the pub - I don’t drink anyway, dh only on occasion, but no like big nights out. Dh and ds go to the barber, but I cut my own hair and dd. No nails. No new clothes unless they are outgrown or can’t be repaired. Since the start of the year, I’ve bought 2 shirts from Primark at a total of £12 and that’s all I’ve spent on clothes this year. I have plenty of clothes at home to wear, so don’t need new ones. No cars on finance, we have old secondhand cars that we maintain well.
None of that because we can’t afford it, more because we don’t need it. No point spending £60 on a takeaway that isn’t nice, when I can make the same at home for £10. We have the usual bills, electric, heating oil, internet, phone, council tax, but I really work to not waste electricity. Or we don’t heat the house unless we need it (it’s a big house, we have 3 fireplaces, we light one if we need it, the wood we get for free when a tree comes down or someone needs a downed tree removed).
I would look at where money is going because it’s almost certainly going on lots of little things that add up into big things without you realising.
