I recently started to do the same for the same reason. Also, I started saving late and want to retire early, so I need to make up for lost time. My partner is older and a much lower earner, he hasn't saved much at all, so I feel like a lot is on my shoulders. However, getting it right feels like a minefield!
My employer contributions are small (7%). And I do worry that I'm not left with much "fun" money. However, I'm also a very frugal person every day (no car, no makeup, low food and heating costs, no gym, no classes, rarely buy new clothes, no commute costs, no coffee bought out etc), which I'm fine with. This means I can spend on bigger things that are important to me (e.g. Nice holidays, day trips, meals out). Having no children helps. But with inflation I worry about my ability to continue this way. I'm looking for a better paid job to help.
The thing that changed me was working backwards from where I wanted to be, to how much I need to put away each month. Previously, I put away 17% per month, but realised that would not give me the money I need to survive at retirement (I have no inheritance coming my way, and no large house to downsize from, and feel like I can't rely on the state pension). I worked out I could afford a much greater contribution.
@Heatherbell1978 Looking at what others are doing can be useful, but it's also good to think about your own goals: Have you worked backwards from the retirement fund you want to how much you need to put away? Have you considered the age you want to retire and the lifestyle you want to have? Have you considered other streams of income or lump sums you might get to help with your retirement? What outgoings will you have (e.g., helping children with wedding costs, house deposit, childcare or private school costs)? Have you thought about the balance between savings in a pension vs other kinds of savings? Have you talked to a financial advisor- for example, they advised me all of my bonus should go in my pension: that was a game changer.
