How Much Should You Have Invested by 25, 30 and 35? A Millennial and Gen Z Guide

Purple Flower

Realistic UK benchmarks for Millennials and Gen Z, without the doom-scroll pressure.

How much should you actually have invested by 25?

There's no single right number, but a useful UK benchmark is half your annual salary in total savings and investments combined by age 25. On an average UK graduate salary of around £28,000, that's roughly £14,000. This figure sounds high, but it usually includes workplace pension contributions from your employer, not just money you've put aside yourself.

If you're well below this, you're genuinely not behind. Most 25-year-olds in the UK have less than £5,000 saved, and many have nothing invested at all. The benchmark is a useful target, not a judgement. What matters most at 25 is not the amount, but whether you've started: opened a pension, opened an ISA, set up a monthly contribution. The habit beats the balance at this age.

How much should you have invested by 30?

A reasonable target is roughly one times your annual salary across all savings and investments. For someone earning £35,000, that's £35,000. For someone earning £50,000, that's £50,000. This target includes pension pots from all current and previous employers, ISA balances, cash savings and any other investments.

This benchmark is deliberately rough because life paths vary enormously in your 20s. Someone who went straight into a graduate scheme at 21 will be further along than someone who studied longer, retrained, started a business, or took career breaks. The benchmark isn't saying you've failed if you're below it, it's saying this is the territory you're aiming for so you're on track for a comfortable retirement.

How much should you have invested by 35?

A common rule of thumb is two times your annual salary by 35. For someone earning £40,000, that's £80,000. Most of this typically sits in a pension (because workplace pensions compound powerfully from your 20s) plus ISA balances and cash savings on top.

By 35, the gap between people who started investing in their 20s and people who haven't becomes visible. A 25-year-old who invests £200 per month at 7% per year will have roughly £35,000 by 35. Someone starting at 30 needs to invest about £355 per month to hit the same target. The cost of waiting becomes real money.

What if you're nowhere near these benchmarks?

The most useful thing is to stop comparing and start acting. The benchmarks exist so you know the direction of travel, not to make you feel behind. Someone at 30 with £3,000 saved and a consistent £200/month contribution going forward will build real wealth over their working life. The people who fall short over a lifetime are usually those who never start, not those who started late.

If you're behind, the single most powerful thing you can do is increase your contributions. Raising your pension contribution from 5% to 8% of salary, or adding £100/month to an ISA, compounds into very different outcomes over 20-30 years. The earlier you make these changes, the more they do.

Why do these benchmarks assume pensions too?

Because in the UK, your workplace pension is a huge part of your total long-term savings, and it's often invisible until you look for it. If you've been working since your early 20s, your employer has likely been contributing 3-5% of your salary to a pension, and you've probably been contributing another 5%. Over five or ten years, that compounds into real money, even if you never actively thought about it.

When benchmarks talk about "half your salary by 25" or "one times by 30", they usually include your pension pot. This is why it's important to log into your pension provider (often Nest, Aviva, or Legal & General for UK workers) and actually check the balance. Most people under 35 underestimate what they already have.

Should you be using an ISA on top of a workplace pension?

Yes, if you can. A workplace pension is excellent for long-term retirement wealth, but you can't access it until you're at least 57 (rising to 58 by 2028). A Stocks and Shares ISA gives you long-term tax-free growth plus the flexibility to access the money earlier if life demands it. Most wealth-building paths use both: pension for retirement, ISA for everything else.

For younger investors, even small regular ISA contributions add up dramatically. £150/month at 7% becomes roughly £37,000 after 15 years, or £85,000 after 25 years. Starting at 25 makes those numbers far bigger by the time you're 45.

Where Mona Fits

Mona is built for the generations who grew up with pension anxiety, housing market dread and the feeling that traditional advice isn't quite for them. Mona's Stocks and Shares ISA lets you start investing from a small amount, automate it, and actually track where you are against benchmarks like these. The goal isn't hitting an arbitrary number, it's building a habit that compounds over the decades you still have ahead of you.

The Bottom Line

Rough UK benchmarks for Millennials and Gen Z are: about half your annual salary invested by 25, one times by 30, and two times by 35, including all pensions, ISAs and savings combined. If you're below these numbers, you're not behind, you're part of the majority, and the fix is to start or increase contributions now. The cost of waiting compounds fast: every five-year delay roughly doubles the monthly contribution required to hit the same target. Use these benchmarks as direction, not judgement. What matters most is whether you're investing at all.
