Question 1

What does $2,000 grow to at 5% for 10 years?

Accepted Answer

$2,000 invested at 5% annual compound interest for 10 years grows to $3,258. Your original investment earns $1,258 in interest — a 62.9% total return and a 1.63× multiplier on your money.

Question 2

How long does it take to double money at 5%?

Accepted Answer

At 5% annual compound interest, your money doubles approximately every 14.4 years (the Rule of 72: 72 ÷ 5 = 14.4). Over 10 years, $2,000 has the potential to double 0.7 times.

Question 3

Is 5% a realistic return?

Accepted Answer

5% is a conservative assumption achievable through high-interest savings accounts or term deposits. It's a realistic baseline for low-risk investments, though actual rates vary with market conditions.

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 5% 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 5% return and 2.5% inflation, your real return is approximately 2.5% p.a. In real terms, $3,258 in 10 years would buy meaningfully less than it does today.
