Question 1

What does $5,000 grow to at 7% for 10 years?

Accepted Answer

$5,000 invested at 7% annual compound interest for 10 years grows to $9,836. Your original investment earns $4,836 in interest — a 96.7% total return and a 1.97× multiplier on your money.

Question 2

How long does it take to double money at 7%?

Accepted Answer

At 7% annual compound interest, your money doubles approximately every 10.3 years (the Rule of 72: 72 ÷ 7 = 10.3). Over 10 years, $5,000 has the potential to double 1.0 times.

Question 3

Is 7% a realistic return?

Accepted Answer

7% 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 7% 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 $5,000 with no additional contributions. Adding regular contributions compounds the growth dramatically. For example, adding $200/month to $5,000 at 7% for 10 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 7% return and 2.5% inflation, your real return is approximately 4.5% p.a. In real terms, $9,836 in 10 years would buy meaningfully less than it does today.
