Crypto Portfolio Calculator

Why aggregate-view matters for crypto portfolios

Most crypto holders track individual positions but rarely look at the portfolio as a whole. That creates blind spots: concentration in one coin can build past the level anyone intended without being obvious, and the combined value determines what is actually at stake. A 70% allocation to a single coin is a concentration whatever that coin has done recently, and the distribution is harder to see from a list of individual prices than from one total.

How the math works

Total portfolio value is the sum of quantity multiplied by price for each coin, and each allocation is that coin's value divided by the total, times 100. The calculator flags concentration when a single position exceeds 50% of the portfolio, a threshold chosen because above it the portfolio's behaviour is dominated by one holding rather than shared across three.

Concentration risk in crypto portfolios

Crypto portfolios tend to be more concentrated than traditional ones. Some holders keep most of their crypto in one or two large-cap coins with smaller satellite positions. Concentration is not automatically a problem, and a portfolio held entirely in one coin can be a coherent position for someone who holds it on conviction. What the tool does is surface the distribution, so the split can be compared against what was intended rather than against what price movement has left behind.

Correlation between crypto assets

Even a diversified-looking crypto portfolio often behaves like a single asset during large market moves, because the major coins have historically been closely correlated with one another. That differs from a traditional mix, where different asset classes have at times moved against each other. On that basis crypto holdings are often sized as one risk position against total wealth rather than treated as a diversified allocation in their own right.

Why prices are user-inputs

The calculator does not fetch live prices. Each coin's current price is a user input, which means the portfolio snapshot is accurate only at the moment you enter the data. For active position management, most holders use exchange dashboards or portfolio tracker apps with live price feeds. The calculator is useful for periodic check-ins, tax record keeping, and scenario analysis (what if BTC drops 40%?) where entering custom prices is the point.

What the tool does not include

Realised and unrealised gains are not tracked, so the tool reads current value regardless of what was paid. Cost basis, staking yields, impermanent loss on liquidity positions and holdings spread across venues are not modelled either. Tax reporting generally needs records the calculator does not hold, and position-level return needs a cost basis, which the crypto cost basis calculator covers.
