Question 1

What does $2,000 grow to at 9% for 5 years?

Accepted Answer

$2,000 invested at 9% annual compound interest for 5 years grows to $3,077. Your original investment earns $1,077 in interest — a 53.9% total return and a 1.54× multiplier on your money.

Question 2

How long does it take to double money at 9%?

Accepted Answer

At 9% annual compound interest, your money doubles approximately every 8 years (the Rule of 72: 72 ÷ 9 = 8). Over 5 years, $2,000 has the potential to double 0.6 times.

Question 3

Is 9% a realistic return?

Accepted Answer

9% is an optimistic but achievable return for growth-oriented share portfolios over long time horizons. The ASX 200 has averaged around 9–10% p.a. including dividends. A 9% assumption requires patience and comfort with short-term market volatility.

Question 4

What's the effect of adding regular contributions?

Accepted Answer

These figures show a one-time lump sum of $2,000 with no additional contributions. Adding regular contributions compounds the growth dramatically. For example, adding $200/month to $2,000 at 9% for 5 years would result in a significantly larger final balance. Use the interactive calculator above to model your own contribution amount.

Question 5

How does inflation affect this result?

Accepted Answer

This calculator shows nominal returns — the dollar figures before adjusting for inflation. Australia's historical inflation rate is around 2–3% per year. To estimate real purchasing power, subtract the inflation rate from your return: at 9% return and 2.5% inflation, your real return is approximately 6.5% p.a. In real terms, $3,077 in 5 years would buy meaningfully less than it does today.
