Using this link and putting in everything joint net income ,including child benefit and maintenance which I think it takes into account. It has us at 73 percent. Not a stealth boast before any states that. Genuinely surprised.
I certainly don't feel like this but appreciate people survive on less. It doesn't take into account mortgages, rent, generational wealth, inheritance, childcare etc so is a guide.
It is eye opening though.
I feel poor compared to my friends though. We definitely are not the London elite. Just public sector workers in the North. I guess the maintenance helps. My friends must be in the top 20 percent.
