A Stocks and Shares ISA can be a good vehicle to try and build wealth over the long term.

If I had a spare £20,000 in an ISA and wanted to try and increase it to £50,000 over coming years, here is how I would go about it.

Growth and income

As an investor in the stock market, there is a choice of growth and income shares. The description is only a rough one. Some shares offer the prospects of business growth and dividend income, while others offer weak growth prospects and no likelihood of a dividend.

Roughly speaking though, it can be a useful way to categorise shares.

To grow the value of my Stocks and Shares ISA, I need either an increase in the price of my shares or dividend income from them.

If I am fortunate, I may get both! When selecting a share to buy though, I ask myself what I hope will be its primary source of wealth-building for me over the years to come. Price growth or dividend income.

If I had a spare £20,000 in an ISA right now, I would put 60% into dividend shares and the remainder into growth shares.

Long-term dividend potential

The sorts of dividend shares I would buy for my ISA would be similar to (and in some cases the same as) ones I already own, like Legal & General and Vodafone.

I would be looking for blue-chip companies with a long-term competitive advantage I think could generate chunky free cash flows to fund dividends.

Some businesses may end up disappointing me. So I would split the £12,000 across a handful of different income shares.

In the current market, I think an average dividend yield of 8% is attainable even while only investing in FTSE 100 companies with proven businesses.

Going for growth

Turning £20,000 into £50,000 is equivalent to growth of 150%. If I could compound my dividends at an annual rate of 8%, the value of my income shares should increase 150% in 12 years.

That example presumes a flat share price and dividend in each case. In practice that is unlikely – both things could move up or down. But it shows how compounding dividends can help to build wealth.

With the remaining £8,000 of my Stocks and Shares ISA going on growth shares, I have to accept that finding attractively priced growth shares can be difficult.

To hit my target, I would be looking for shares in dynamic businesses with strong growth prospects. I would want to buy at a valuation I think could allow for an increase in value 150% over the coming decade or so.

In the past decade such a return was achieved by growth shares like JD Sports and Ashtead.

Past performance is not a guide to what will happen in future. But I would look now for similar characteristics to those such companies had a decade ago, namely a large target market, strong competitive advantage and proven business model.

As well as that, valuation is critical. I do not just want to find business I think have strong growth prospects. I also want their shares to be attractively priced.

Should you invest, the value of your investment may rise or fall and your capital is at risk. Before investing, your individual circumstances should be assessed. Consider taking independent financial advice.
