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 $250,000 would have the purchasing power of approximately $99,997 in today's dollars. Inflation reduces buying power over time, which is why investing to outpace inflation is important.
Frequently Asked Questions
How long does it take to save $250K with $200 per month?
At a 7% annual return, saving $200 per month, it takes approximately 30 years 4 months to reach $250,000.
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.
