Turning an empty ISA into a £3,134 monthly passive income

Is it possible to go from no savings to a £3,134 passive income per month? With a share investing plan via an ISA, I’d say it is.

If I had no savings, then any idea of passive income would seem a long way off. Unfortunately, this is the reality for anyone who hasn’t started using their ISA allowance yet.

But let’s say I had an empty ISA and nothing else. I think I could target a £3,134 monthly passive income, even without saving anywhere near the yearly deposit limit. Here’s how. 

My strategy begins with saving a little cash. After all, my ISA won’t do anything while it’s still empty, and the more money I can put in there, the more passive income I can work towards. 

I think £250 per month seems like a good starting point. At £3,000 a year, it’s miles away from the ISA deposit limit of £20,000. Regardless of the amount, all my earnings from the account are mine rather than the taxman’s. 

The problem though, and a very big one at that, is that saving alone is not nearly enough.

£250 a month
1 year£3,000
5 years£15,000
10 years£30,000
20 years£60,000
30 years£120,000

Even if I had to scrimp and save to build this, after 10 years I’ve only got £30,000. After two decades, I would have less than the average house deposit. 

A Cash ISA would give me better returns, it’s true. I can get up to 6% in some accounts right now, and the interest I get is guaranteed. On the surface, that sounds like a good way to grow my money. 

8% inflation

But 6% means I’m losing money in real terms compared to 8%+ levels of inflation. And the return I get from these accounts is always tied to interest rates and therefore inflation. If I’m not beating inflation, then I’m not actually growing wealth. 

The solution instead is a Stocks and Shares ISA. Investing in stocks has proven for decades and centuries to be the best wealth-building tool the average person has available to them. I use my ISA to invest, to own a small part of a company. As it makes money and grows, my money grows too.

The return from investing in stocks and shares is variable. Here are a few examples.

£250 a month
0%7%10%13%
1 year£3,000£3,113£3,160£3,207
5 years£15,000£17,890£19,293£20,784
10 years£30,000£43,005£50,364£59,078
20 years£60,000£127,602£180,997£259,621
30 years£120,000£294,016£519,823£940,379

This table really shows the power of a Stocks and Shares ISA. And the difference between the 7% return and the 13% return shows how important good stock choices are. 

The 10% return is what many people aim for with stocks. It’s in line with the historical returns from big firms in the US and UK. For this reason, a lot of investors like to put money in funds that track an entire stock market index.

£3,134 a month

This strategy isn’t risk-free. No returns are guaranteed and many individual companies do go bankrupt. I can limit these risks with diversification, and I do make sure my holdings are spread out  across many sectors. 

If I was to build my empty ISA up to that £940,379 value, I could then safely withdraw at 4% yearly. As a passive income, that would give me an attractive-sounding £3,134 a month. In the future, that would be worth less due to inflation, but still, it shows why I see investing as the best path to another income stream.
