I have to admit that me and DH do have good savings, and could survive for quite a while if one of us lost our job. But no way do we save £2000 a month, and we never have. (And we have very low outgoings now!)
As I said, most people don't save that much.
We are mid 50s now. our kids are independent/got their own home, and we are mortgage free, and we save £750-£900 a month at the most. Occasionally it's a bit more, and some months it's less if we have extra outgoings - like an unexpected car bill or vet bill, or if we do more socialising than normal, or go away on holiday, or if it's Christmas, or if something needs doing in the house. Also saw some our savings go when we helped DD and her now husband fund their wedding! 😬
We spent the first 20-22 years of our marriage though, never cracking 4 figures with our savings. It's only been since our two DC left home, which coincided with us being mortgage free that we started to notice our finances were much healthier! Literally just the past 7-8 years. We were stunned at how much surplus cash we had with no kids to support, and no mortgage. We still never save £2000 a month though!
We do both work 22-26 hours a week though and not full time. So we may save more if we were full time, but then, tax, and national insurance, and private medical insurance through work, and our work pension contributions would be higher, so we may not bring home masses more even if we increased our hours!)
As I said though, we were virtually 50 before we started to have quite a bit of surplus income.
