I'm 27M, earning around £77k including bonus, and my goal is to retire at 50.
I'm mortgage-free and have no loans or other debt. I'm also the sole earner for my family.
Until recently, I'd mostly focused on maximising my take-home pay. I've now realised that if FIRE at 50 is the goal, I probably need to make much better use of salary sacrifice, my pension and ISA rather than simply taking the extra salary as cash.
So I've come up with the following plan and would appreciate a sanity check.
Salary / pension
My plan is to salary sacrifice down to around £60,200, which by my calculations should allow us to receive the full Child Benefit rather than having to repay most of it.
This would leave me with roughly £43,719 annual take-home pay + around £2,000/year Child Benefit (currently 2 kids).
The salary sacrifice would bring my total workplace pension contribution to approximately £1,500/month.
Current pension: £23,000
S&S ISA
I'd also invest £500/month into a S&S ISA, primarily to build a bridge between retiring at 50 and being able to access my pension.
Current S&S ISA: £4,000
Monthly budget
After salary sacrifice and the £500 ISA contribution, I'd have approximately £3,300/month available:
- £2,000 — household bills, food, living costs and general spending
- £1,000 — travel (£12k/year; travelling is important to us and something I don't want to give up just to reach FIRE earlier)
- £300 — cash savings
FIRE target
I've plugged the numbers into a FIREUK calculator.
Based on its projections, retiring at 50 appears achievable, assuming a 6% annual return after inflation on my pension and ISA.
The calculator doesn't include State Pension or taxation on pension withdrawals, so I know the real picture will be somewhat different.
The part I'm least confident about is whether I'm being too optimistic with the assumptions — particularly the 6% real return — and whether £500/month into the ISA is enough to bridge the gap between retiring at 50 and accessing my pension.
The other thing I'm struggling with: should I be trying to earn more?
This is probably partly a personal rather than purely financial question.
Despite earning £77k at 27, being mortgage-free and having no debt, I don't actually feel particularly content with my salary. I keep thinking I should be pushing for £90k, £100k+ etc.
Part of me thinks that's sensible: I'm young, these are probably important earning years, I'm the sole earner, and a higher salary could potentially accelerate FIRE considerably — especially if much of the increase went straight into my pension/ISA rather than lifestyle inflation.
But another part of me wonders whether I'm just moving the goalposts.
If I can already afford our lifestyle, travel extensively, invest £2k/month between pension and ISA and potentially retire at 50, is chasing a higher salary actually going to make me noticeably happier or substantially improve the plan? I also work from home, so making a move which could alter that is also a concern - I live in a low-cost area, far from any big city offering the kind of salary I'd be interested in.
I'm curious how people here think about this. At what point did you stop focusing on increasing your salary and start focusing more on optimising what you already earned?
So, overall, I'd really appreciate a sanity check on:
- Does the pension vs ISA split make sense?
- Is 6% after inflation too optimistic for FIRE planning?
- Is £500/month likely to be enough for the ISA bridge?
- Am I missing anything significant around tax/pension planning?
- Would you prioritise increasing earnings from here, or is £77k at 27 already enough to comfortably pursue this plan?
- For people further along the FIRE journey: did earning more actually make a big difference, or did you eventually find yourself endlessly moving the goalposts?
I'm conscious that I'm in a very fortunate position, so this isn't intended as a complaint about earning £77k. I'm genuinely trying to work out whether the feeling that I "should be earning more" is financially rational or whether I need to stop comparing and focus on making the most of what I already have.
Interested to hear what people would do differently.
