Question 1

What does $1,000 grow to at 6% for 25 years?

Accepted Answer

$1,000 invested at 6% annual compound interest for 25 years grows to $4,292. Your original investment earns $3,292 in interest — a 329.2% total return and a 4.29× multiplier on your money.

Question 2

How long does it take to double money at 6%?

Accepted Answer

At 6% annual compound interest, your money doubles approximately every 12 years (the Rule of 72: 72 ÷ 6 = 12). Over 25 years, $1,000 has the potential to double 2.1 times.

Question 3

Is 6% a realistic return?

Accepted Answer

6% is a moderate return that aligns with long-term historical averages for diversified share portfolios. The ASX 200 has returned around 9–10% p.a. including dividends historically, so 6% is realistic over long periods after accounting for fees and portfolio mix.

Question 4

What's the effect of adding regular contributions?

Accepted Answer

These figures show a one-time lump sum of $1,000 with no additional contributions. Adding regular contributions compounds the growth dramatically. For example, adding $200/month to $1,000 at 6% for 25 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 6% return and 2.5% inflation, your real return is approximately 3.5% p.a. In real terms, $4,292 in 25 years would buy meaningfully less than it does today.
