How I’d invest £300 a month in a Stocks and Shares ISA to target £12k a year

Owning dividend stocks is a time-tested way to build a passive income stream. I do that using a Stocks and Shares ISA. By regularly drip-feeding money into it, I hope to build a sizeable up sizeable passive income over time.

As an example, if I want to target £1,000 per month with an average income (£12,000 per year), this is how I set aside £300 per month.

Regular savings

My first step would be to get into regular saving habits. That way, I hope I’ll stick with it even if other spending needs arise.

Everyone has their own financial situation. I think the important thing is to set a savings goal that looks realistic given your specific circumstances.

I will put the money into a Stocks and Shares ISA from today. That way, if I have saved enough money and know what I want to invest in, I will be ready to act immediately.

Find stocks to buy

Investing is something that I see as a long-term endeavor. So my plan to generate quarterly passive income from dividend stocks will take decades not months.

That means when I buy stocks, I don’t chase the latest trends. Instead, I will hunt to find businesses that I think have a profitable foundation that can last for decades.

So, I would look for companies in areas with large and resilient customer demand that have a competitive advantage. For example, brands from Unilevernetwork National Gridand technology patents from Apple all competitive advantages I do not compete can be directly matched.

I also looked at the company’s balance sheet. If there is a lot of debt, it may reduce the prospect of dividends even if the business is profitable. After all, dividends are never guaranteed in any company.

Aim for passive income goals

Another consideration is the share price. That’s important in part because the returns I get on stocks vary according to what I pay for them.

How much I should invest to try and reach my monthly target of £1,000 depends on the average return of my portfolio. If it’s 5%, for example, I’d need £240,000 invested in a Stocks and Shares ISA.

To save £300 a month would take 67 years. I can cut that time by more than half if I reinvest the dividends, which is called compounding. If I do that and continue to earn an average of 5%, I could be earning £1,000 a month in dividends three decades from now.

On top of that, I will have a fairly large portfolio in my Stocks and Shares ISA. Depending on my choice, that can provide passive income for the rest of my life.
