Formula and methodology
Formula: Periodic volatility=population SD of returns; annualized volatility=periodic volatility×√periods per year.
Scaling by the square root of periods is a planning convention for comparable equally spaced returns, not a guarantee of future risk.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Periodic returns — Comma-separated decimal returns.
- Periods per year — minimum 1.0E-6; maximum 10000
Worked example
| Input | Value |
|---|---|
| Periodic returns | 0.02, -0.01, 0.03, 0.00, 0.01 |
| Periods per year | 12 |
Periodic volatility ≈1.414%; annualized volatility ≈4.899%.
Assumptions and limits
- Returns are equally spaced and represented as decimals.
- Population standard deviation is used for the supplied list.
- Serial correlation, fat tails, changing regimes, fees, and downside-only risk are not modeled.
