Crypto Portfolio Allocation Calculator

About this calculator

Crypto portfolio allocation is the practice of dividing a total investment across different cryptocurrencies according to target percentage weights — typically a mix like Bitcoin (often the largest, ‘core’ holding due to its liquidity and relative track record), Ethereum (the leading smart-contract platform), and a basket of altcoins for higher-risk, higher-potential-reward exposure. This mirrors the traditional-finance concept of strategic asset allocation, adapted to a market known for far higher volatility and correlation swings than stocks or bonds.

Retail crypto investors and portfolio-tracking tools use target-weight allocation to decide how to split new capital or to identify when a portfolio has drifted from its intended weights after a rally in one asset (a scenario that commonly calls for rebalancing — selling some of the outperformer and buying more of the underperformer to restore the target mix), since letting winners run unchecked can quietly concentrate risk in a single coin far beyond the investor's original intention.

This calculator takes your total investment amount and your target percentage weights for BTC, ETH, and altcoins, and returns the exact dollar amount to allocate to each so you can execute your intended split.
