The beauty of dividend income lies in its ability to generate money while I sleep. This provides me with a sense of financial stability and freedom.

Other passive income options require substanital effort and time. However, dividends allow me to reap the rewards of my investments without actively working for them.

Furthermore, the power of compounding further amplifies the benefits of dividend income. How? Well, the reinvestment of dividends can exponentially grow my portfolio over time.

With this in mind, here’s how I’d invest £10,000 in high-yield FTSE 100 shares to aim for a monthly passive income of £250.

FTSE 100 income shares

The FTSE 100 index comprises the top 100 companies listed on the London Stock Exchange by market capitalisation. It represents a diverse range of industries and sectors.

In my eyes, what makes Footsie shares particularly attractive for generating passive income is a combination of high yields and consistent history of dividend payments by a handful of these companies.

These particular firms often have stable business models, strong cash flows, and established market positions. Each of these factors contribute to their ability to generate consistent profits and distribute a portion of those earnings to shareholders.

By carefully selecting companies with a history of consistent dividend payments and a sustainable dividend policy, I can build a diversified portfolio that helps mitigate risks and optimise income potential to achieve and even exceed my initial goal of £250 a month in passive income.

Earning a £250 monthly second income

It’s impossible for me to instantly earn £250 a month in dividend income from an initial £10,000 investment in a diversified basket of FTSE 100 shares.

However, over time, the power of compound returns will enable me to reach an investment pot capable of earning me a passive income of that size.

To illustrate, let’s say I achieve an 8% annualised return on my £10k investment. After 18 years, I’d have around £39,000.

Assuming I could continue to earn an average yield of 8% from my holdings, I’d receive £3,120 a year in dividend income. This translates into a monthly second income of £260.

Average annual rate of return

Achieving an 8% return won’t be easy. Thankfully for me, there are currently a handful of FTSE 100 companies that are forecast to yield above 8%.

Take British American Tobacco (8.2% yield), Taylor Wimpey (9.1% yield), and Legal & General (8.5% yield), for example.

That said, dividends are never guaranteed. Unpredictable events such as recessions, regulatory changes, or shifts in consumer behaviour can impact a company’s ability to maintain dividend payments.

Nevertheless, diversification and a long-term perspective will help me to mitigate the risks associated with dividend income.

Ultimately, regardless of the companies I choose to invest in, if I commit to a disciplined investment approach that focuses on quality FTSE 100 companies and reinvesting dividends over the long term, I could steadily increase my passive income and even potentially exceed my initial goal of £250 in monthly passive income.

Matthew Dumigan has no position in any of the shares mentioned. The Motley Fool UK has recommended British American Tobacco P.l.c.
