Passive income, the art of earning regular cash flow with minimal day‑to‑day involvement, is a goal many investors chase. And regular dividends paid by shares are the best way yet that I have found of achieving this.

The big housebuilders have long been fertile ground for dependable dividends, and Taylor Wimpey (LSE: TW) stands out among them to me. Its strong cash generation and commitment to shareholder returns underpin a generous payout profile.

So, how much could another £20,000 investment in the shares make?

What’s going to power the dividends?

Generous dividends ultimately depend on a business that keeps generating healthy earnings.

One risk for Taylor Wimpey here is rising interest rates that could mute the strength of the housing demand recovery. Another is cost pressures lingering for longer, capping margin expansion.

Nonetheless, the consensus analysts’ forecast is that its earnings will rise by an average 20.7% a year over the medium term at least.

Do results support this view?

In its last major results (full-year 2025), revenue increased 13% year on year to £3.84bn. That reflected higher volumes and a firmer pricing backdrop in key regions. Return on net operating assets improved to 11% from 10.9%, as newer, higher‑margin land began to flow through.

And home completions rose 6% to 11,229, highlighting the early benefits of Taylor Wimpey’s outlet‑led growth strategy. This entails opening more active sales outlets on land it already owns, rather than relying on big new land buys.

Meanwhile, adjusted operating profit edged up 1% to £420.6m. This illustrated disciplined cost control and the resilience of the company’s standardised build model despite lingering inflation.

Together, these trends suggest a business rebuilding operational leverage and laying the foundations for sustained earnings growth ahead.

What’s the potential dividend income?

Taylor Wimpey has increased its dividend since 2021 from 8.28p then to 9.33p in 2025. The rising payouts generated respective annual average dividend yields of 4.7%, 8.9%, 6.5%, 7.9%, and 8.7% over that period.

These up-and-down yields, despite a sustained rise in dividends, highlight that these returns can change as share prices move.

However, analysts forecast the firm’s dividend yield this year at 7.4%, next year at 8.6%, and in 2028 at 8.9%. By contrast, the current average FTSE 100 dividend is just 3.1%, and the FTSE 250’s is 3.4%.

So, another £20,000 investment by me at the forecast 8.9% yield as an average would make £28,543 in dividends over 10 years. The figure factors in the payouts being reinvested into the shares to utilise the full supercharging effect of dividend compounding.

After 30 years on the same basis, the dividends would increase to £265,968. With the £20,000 original investment included, the total value of the holding would be £285,968.

And that would deliver a yearly income of £25,451 by then!

My investment view

I believe the strong earnings projections for the firm should comfortably support the projected ultra-high dividend yields.

And these can lead to significant yearly income, once the turbocharging effect of dividend compounding kicks in over time.

As such, I have no hesitation in adding to my existing holding very soon.

I also have my eye on other very high-yielding shares that look deeply undervalued to me, in other sectors.
