How Much Should I Save Each Month?
It’s great that you’re able to commit to saving £500 each month. However if you haven’t already done so, it’s worth stepping back for a second and asking a few more basic questions: how much should I save each month?
The first step to answer this question is understanding your personal financial goals. Are you saving for a house? Retirement? Emergency fund? Your child’s education? Or maybe all of these?
The amount you should save every month largely depends on these goals. For example, if you’re saving to buy a house, the required amount may be different compared to saving for retirement.
Your income also plays a crucial role in determining the appropriateness of saving £500 per month. For someone earning £50k a year, saving £500 means setting aside 12% of their monthly income. That is a good savings target.
Last, but not least, expenses play a significant role in determining how much to save each month. Expenses include the obvious like rent, food, but also things like mandatory debt payments on credit cards.
Higher expenses mean you have less money to save. Therefore, it’s important to assess your monthly expenses and work on reducing unnecessary spending.
Let’s consider an example with some numbers: If you are in your mid-60s, retiring today, and want to withdraw £40,000 annually from your portfolio, you will need approximately £1 million in your portfolio. This assumes that you will live till 100 (~35 years to go!) and that inflation over that period is 2%. The table below shows how much you’ll need to save each month to build up a million pound portfolio.

As you can see, how much you need to save depends on two key factors: time (or your age) and your rate of return. If you can make do with a lower expenses in the future, then of course you will also need to save less to hit your ultimate goal.
Of course if you are young, then you will also have to remember that due to inflation, £40,000 of living expenses in today’s terms will be a much higher figure in the future. If you’re 30 years old now and plan to retire at 65, in inflation-adjusted terms your annual requirement will actually be £80,000.
All of this can be too tough to calculate mentally, so we’ve got a helpful retirement calculator which you can use to plan out in greater detail what your eventual retirement looks like. I recommend giving it a try!
What’s the best way to invest £500 per month?
The best way to build up a huge portfolio with a £500 a month in savings is arguably through investing. However before we get there, it’s first important to look at the full picture.
- Eliminate debt: As boring and repetitive as it sounds, it makes sense to first eliminate your debt – especially high interest rate debt such as credit card debt or other consumer loans like car loans or those buy-now-pay-later type debt.
- Build Up Your Emergency Fund: Again, another piece of unsexy advice, but it’s important to build up your emergency fund with cash savings that has at least 3 months, but preferably 6 months of expenses. You can invest your emergency fund in a high interest savings account or perhaps even put it in a money market fund.
- Invest it: Finally we get to the most fun piece. It’s important to invest your money in a way that aligns with your needs and risk tolerances. Depending on your needs you may choose to go with balanced funds or perhaps go all out with 100% equity funds. It’s important to manage your portfolio prudently, but being overly conservative is not recommended as you will end up sacrificing long-term returns.
If you need help with this, a good way to start would be to educate yourself and to meet with a financial advisor who has fiduciary duty towards you. They will help you decide how to structure your portfolio. Some people have a preference for capital growth whereas others may want dividend income.
