Crypto volatility calculator

Paste a series of prices (daily closes work well) and get the standard deviation of the returns — the daily volatility — plus the annualised figure that lets you compare one asset against another. More scattered returns mean a bigger number.

Enter Prices (chronological), Periods per year and the Crypto volatility calculator works out Volatility per period, Annualised volatility, Returns used straight away. For instance, with Prices (chronological) = 100, 108, 102, 115, 110, 125, 118 and Periods per year = 365 it returns Volatility per period = 9.32%, Annualised volatility = 178.02% and Returns used = 6.

How to use it

  1. Enter your values: Prices (chronological), Periods per year.
  2. Read the result instantly: Volatility per period, Annualised volatility, Returns used.

Frequently asked questions

How does the Crypto volatility calculator work?

It takes Prices (chronological) and Periods per year and derives Volatility per period, Annualised volatility and Returns used from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

2 values: Prices (chronological) and Periods per year. Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With Prices (chronological) = 100, 108, 102, 115, 110, 125, 118 and Periods per year = 365, the calculator returns Volatility per period = 9.32%, Annualised volatility = 178.02% and Returns used = 6. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

How much does the result change with different inputs?

It moves a lot. Using Prices (chronological) = 100, 113, 112, 132, 132, 156, 153 and Periods per year = 730 instead, Volatility per period goes from 9.32% to 9.66% — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Prices (chronological) = 100, 108, 102, 115 and Periods per year = 183, Volatility per period comes out at 9.5%. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Comparing two investments that pay at different times, deciding whether a project clears its cost of capital, and sanity-checking a valuation someone else produced.

What is the most common mistake?

Trusting a valuation without asking what share of it comes from the terminal value. Past 70%, the answer is an assumption about the distant future dressed up as a calculation.

What is the difference between the Crypto volatility calculator and the Crypto DCA calculator?

This one returns Volatility per period and Annualised volatility; the Crypto DCA calculator returns Purchases and Total invested. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Crypto invoice / payment QR generator is the closest one after this: Turn your own receiving address plus an amount, label and message into a standard payment link (BIP-21 for Bitcoin) and a scannable QR code. The address is checksum-verified as you type, and no key is ever generated: you supply your own receiving address.

What else is worth having open alongside it?

Crypto lending / borrowing calculator and Crypto market cap calculator — they come up in the same task often enough to be worth a second tab.

ExplainerVolatility Is Not Risk, and the Square Root of Time Is a ChoiceAnnualised volatility = period standard deviation × √(periods per year), and that √t scaling assumes independent increments. It is a model, not arithmetic: at a daily autocorrelation of 0.1 a 60 percent annualised figure should read 66.3. The payload is volatility drag — the arithmetic mean exceeds the geometric by about σ²/2, so at 8 percent average return and 40 percent volatility the compound outcome is zero.ComparisonCrypto Market Cap vs Trading Volume: What Each Number Can and Cannot Tell YouMarket cap is price times circulating supply — an arithmetic product, not money invested. Volume is what actually changed hands. Here is what each measures, how their ratio exposes a thin market, and where fully diluted valuation fits.ExplainerHow Staking Rewards Actually Work: Nominal Rate, Compounding, and What Eats ItAn advertised 8 percent becomes 8.33 percent once daily rewards compound — and then 7.46 percent after a 10 percent validator commission, and less again after unbonding time. Here is each step, with the arithmetic laid out.ExplainerWhat Is Slippage in Crypto? Price Impact, Tolerance and What It CostsPrice impact is arithmetic: on a constant-product pool it equals your trade size divided by the reserve plus your trade. Here is the formula, a table of trade size against impact, and why the setting called slippage tolerance changes none of it.ExplainerImpermanent Loss Explained: What Providing Liquidity Really CostsImpermanent loss is not a fee and it is not temporary: it is the gap between your liquidity position and simply having held the two tokens. Here is the formula, a table of price change against loss, and the fee income you would need to come out ahead.ExplainerThe Sharpe Ratio, and What It Quietly AssumesSharpe = (return − risk-free) ÷ standard deviation, so it prices return per unit of volatility — and volatility is symmetric. Two funds can share a Sharpe of 0.4939 while their Sortino ratios are 8.59 and 0.74. Annualising by √12 assumes independent returns: at an autocorrelation of 0.2 the published figure is 20 percent too high.
