Frequently asked questions

How long does it take $200,000 to double at 25%?
Using the Rule of 72, money doubles approximately every 3.1 years at 25% annual return. Starting with $200,000, you'd reach $400,000 in roughly 3.1 years. At 25% over 15 years, your money multiplies 40.91× — doubling 5.4 times.
Is 25% a realistic annual return?
25% is an aggressive assumption — above the S&P 500's ~10% historical average. Individual stocks, sector ETFs, or leveraged positions may achieve this, but it's not reliable for planning purposes. Financial planners typically use 6–8% for retirement projections. Use 25% to model optimistic best-case scenarios.

With simple interest at 25%, $200,000 earns $50,000 per year — $750,000 total over 15 years (final: $950,000). With compound interest, the same principal grows to $8.18M — $7.23M more. The gap accelerates over time.
