How Much Should You Be Saving in Your 40s to Retire Comfortably?
Your future self will thank you….
If you're in your 40s and feeling like retirement is starting to appear on the horizon, but still far enough away to feel slightly out of reach, you are not alone.
This decade is often when life is at its busiest: careers are in full swing, kids at home, maybe your parents need help too and your finances feel like they're being pulled in every direction. You are time poor but it's a critical time to take stock of your retirement plans, and if needed, act.
So, how much should you be saving right now to retire comfortably?
What Does “Comfortably” Even Mean?
Retirement is deeply personal, and "comfortable" means different things to every one of us.
As a rough guide, you might want to consider the “replacement rate” rule:
Most people aim to replace around 50–70% of their pre-retirement income (after tax) to maintain their lifestyle.
So, if you're earning £80,000 a year now, a retirement income of £40,000–£56,000 might feel right—depending on your lifestyle, debts, and plans.
Your 50s Are Approaching
If you're in your early 40s, you may still have 20–25 years before retirement. That’s plenty of time to plan, but not so much time that it can be ignored.
If you're starting now, the general guidance is:
Aim to save around 20–25% of your gross annual income each year toward retirement, including pension contributions and ISAs.
This can sound like a lot - but don’t panic. This figure includes employer contributions, tax relief, and any existing pension growth. You're not starting from zero.
Realistic Savings Examples
Let’s say you’re 42, earning £70,000 a year, and you’ve already built up £100,000 in pensions and ISAs.
To target a retirement pot of around £700,000–£1 million by age 67, you might:
Contribute £1,000/month into your pension (including employer contributions)
Top up with £200–£400/month into a Stocks & Shares ISA (for flexibility pre-retirement)
Review your investment strategy to make sure your money is working hard
This plan assumes moderate investment growth of 5–6% and no big interruptions.
The 3 Mistakes We Often See in This Age Group
Relying too heavily on the state pension
It’s valuable, but very unlikely to be enough on its own. At today’s rate, it’s around £11,500 per year.Not increasing contributions as income grows
Promotions and bonuses often come along in your 40s. Keeping your savings rate flat is a missed opportunity.Assuming your mortgage being paid off is enough
You might plan to downsize when the children move out - whilst that helps, it’s not a substitute for long-term income planning.
This Is the Perfect Time to Work with a Financial Planner
Your 40s are the perfect time to take a step back, check you're heading in the right direction, and build confidence in your plans. A financial planner can help you do this by:
Seeing if you are on track and if needed making suggestions around any adjustments
Modelling different retirement ages and lifestyles and helping you to visualise what your retirement could look like
Ensuring that you are making the most of tax allowances and employer benefits
Chatting through any areas you may have overlooked, for example, protection, inheritance, or planning for education costs
In Summary
Your 40s might be the busiest (and most expensive) years of your life—but they’re also the most powerful for shaping your retirement outcome. Consider the following:
Aim to save 20–25% of your income
Use pensions, ISAs, and employer contributions wisely
Avoid the “set and forget” trap
