Browse MathsHow it works
The formula is the same for any percentage question: result = base × (percent ÷ 100). Here, $150,000 ×
(20 ÷ 100) = $30,000. A lump sum like this is a common way to start building an investment portfolio —
putting in a meaningful amount upfront gives it time in the market sooner, while the remaining balance is built
up gradually through smaller regular contributions. Moneysmart’s
guide to developing an investing plan
covers how to set a target, timeframe and risk level before you start.
Worked example
Harrison lives in Toowoomba, Queensland, and wants to build a $150,000 share portfolio over the next several years as a long-term investment alongside his super. Rather than wait until he’s saved the full amount, he’s decided to start with a lump-sum contribution of 20% of his target and add to it regularly from his pay. The calculation: $150,000 × 20% = $30,000. That’s Harrison’s opening contribution, invested in a diversified index fund through his broker. He’ll top up the portfolio with smaller regular contributions over the next few years, using dollar-cost averaging to reach his $150,000 target rather than trying to invest it all in one go.

20% of $150,000 is $30,000. Multiply $150,000 by 0.20, or divide by 5, to get the same answer.
Why start an investment portfolio with a lump sum instead of investing it all at once?
A lump-sum contribution gets that money working in the market sooner, while spreading the remaining balance across regular contributions — dollar-cost averaging — smooths out the effect of market ups and downs and fits around a regular income.
What should I think about before I start investing?
Moneysmart recommends setting your financial goals, risk tolerance and investment timeframe first, and reviewing your existing debts and savings buffer, before committing money to a portfolio.
How much would a 10% starting contribution be on the same $150,000 target?
