Where:
Explanation: The formula calculates how an initial investment grows over time with compound interest, reflecting the historical performance of Vanguard index funds.
Details: Understanding potential investment growth helps with retirement planning, financial goal setting, and making informed investment decisions. Historical Vanguard index fund returns typically range from 7-10% annually.
Tips: Enter principal investment in USD, annual return rate as a decimal (e.g., 0.07 for 7%), and investment period in years. All values must be positive numbers.
Q1: What are typical Vanguard index fund returns?
A: Historically, Vanguard index funds have delivered annual returns between 7-10%, though past performance doesn't guarantee future results.
Q2: Is this calculator accurate for real-world investing?
A: This provides an estimate based on constant returns. Actual investments may fluctuate due to market volatility and other factors.
Q3: Should I use the lower or higher end of the 7-10% range?
A: Conservative estimates typically use 7%, while optimistic projections may use 10%. Many financial planners recommend using 7-8% for long-term planning.
Q4: Are there fees or taxes considered in this calculation?
A: This calculator shows gross returns. Actual net returns will be lower due to expense ratios, management fees, and taxes on investment gains.

A: Compound interest allows earnings to generate their own earnings, creating exponential growth over longer time periods.
