A $20,000 investment has the potential to become a much larger amount over time.
I think the key is approaching it the right way. Trying to turn $20,000 into $100,000 quickly can push investors towards risky choices, overhyped and speculative stocks, or businesses they do not really understand.
I would rather think about the question through the lens of compounding.
The target is a fivefold return. That sounds ambitious, but it does not require a miracle if the investor has enough time and owns the right types of assets.

What to target
If an investor achieved an average annual return of 9%, a $20,000 investment could grow to $100,000 in roughly 19 years.
That return is not guaranteed. Some years could be excellent, some flat, and some negative. But I think a 9% annual return is a useful long-term assumption for understanding how wealth can be built through ASX shares.
What stands out to me is that the investor does not need to find a stock that rises fivefold next year.
They need a sensible return, repeated over a long period.
That is the part of investing that often gets overlooked. Wealth is not only built by spotting one spectacular winner. It can also come from owning quality businesses, reinvesting returns, and giving the market enough time to work.
What I'd buy
If I were trying to turn $20,000 into $100,000, I would focus on quality and growth.
That could include a broad ASX exchange-traded fund (ETF) for simple market exposure, such as the Vanguard Australian Shares Index ETF (ASX: VAS) or the iShares S&P 500 AUD ETF (ASX: IVV). This would give investors exposure to a wide range of Australian and US stocks in one investment.
But I would also want exposure to individual businesses that could grow earnings at a good rate over time.
For example, REA Group Ltd (ASX: REA) has one of the strongest digital platforms in Australia through realestate.com.au. Its market position offers several avenues for growth through premium listings, data, agent tools, property insights, and finance leads.
Macquarie Group Ltd (ASX: MQG) is another type of long-term compounder I like. It has exposure to asset management, infrastructure, commodities, private capital, and global markets. Its earnings can move around, but its ability to adapt has been a major strength over time.
I would also look at businesses with strong brands and global opportunities. Breville Group Ltd (ASX: BRG) is a good example. It has built a premium appliance brand with growth potential across coffee and kitchen products, as well as international markets.
Patience is the hard part
The biggest challenge is not the calculation. It is staying invested.
A 19-year journey will almost certainly include market sell-offs, recessions, disappointing company updates, and periods where investors feel like nothing is happening.
That is normal. The danger is giving up too early, selling quality shares during weak periods, or constantly jumping between ideas in search of faster returns.
If the investment case remains intact, I think time can be a powerful advantage.
Foolish Takeaway
Turning $20,000 into $100,000 with ASX shares is possible, but I think investors need the right mindset.
The goal is not to force a quick fivefold return. It is to own assets that can compound steadily and give them enough time to grow.
A 9% annual return could get the job done in roughly 19 years. That may not sound exciting at first, but I think that is the point. Successful investing often looks ordinary in the early years before the results become impressive later on.
