FAQ

How to calculate investment returns?

The core formula is: Future Value = Principal × (1 + Annual Return)^Years. For periodic investments: FV = Periodic Investment × ((1 + Rate)^Periods - 1) / Rate. This tool supports both lump sum and regular investment modes.

What is CAGR (Compound Annual Growth Rate)?

CAGR measures the mean annual growth rate of an investment over time. Formula: CAGR = (End Value/Start Value)^(1/Years) - 1. It smooths out annual fluctuations. For example, doubling money in 3 years ≈ 26% CAGR.

How does compounding frequency affect returns?

Higher compounding frequency generates more returns: daily > monthly > quarterly > annually. Differences are modest in the short term but significant over decades. For example, $100K at 10% for 10 years: annually = ~$259K, daily = ~$272K.

Is this tool's calculation accurate?

This tool uses standard financial mathematics formulas for accurate results. Actual investments may involve taxes, fees, and market volatility. Use this as a reliable reference tool; it does not constitute investment advice.
