The Rule of 72

Your money doubles approximately every 10.3 years at 7% return. This is calculated using the Rule of 72: divide 72 by your annual return rate to estimate doubling time. At 4% it takes ~18 years, at 5% ~14.4 years, and at 10% ~7.2 years.

Inflation-Adjusted Value

After adjusting for ~3% average annual inflation, your $81,165 would have the purchasing power of approximately $33,439 in today's dollars. Inflation reduces buying power over time, which is why investing to outpace inflation is important.

Frequently Asked Questions

How much will $10,000 grow to in 30 years?

$10,000 invested for 30 years at 7% annual return grows to approximately $81,165. That's $71,165 in compound interest earned on your initial investment.

What is the power of compound interest?

Compound interest means you earn returns on both your original investment and on the returns already earned. Over long periods, this creates exponential growth — your money starts growing faster and faster. Einstein reportedly called it the eighth wonder of the world. At 7% annual returns, your money doubles roughly every 10 years.

Should I save in a bank or invest?

Bank savings accounts in Australia typically earn 4–5% interest and are guaranteed by the government up to $250,000. Investing in diversified index funds or ETFs has historically returned 7–10% per year on average but comes with short-term volatility. For money you need within 1–2 years, a high-interest savings account is safer. For goals 5+ years away, investing generally produces better long-term results after inflation.
