Crypto Portfolio Allocation Calculator
Understanding your portfolio allocation is the first step to managing risk. Enter the name and current value of each cryptocurrency you hold and this calculator will compute each asset's percentage weight, your total portfolio value, and the dollar value of each position. You can add up to 10 assets. Values are entered in USD (or any consistent currency); no live price data is used.
Portfolio allocation formula
Weight(i) = Value(i) / Sum of all Values x 100%
Total Portfolio Value = Sum of Value(1) + Value(2) + ... + Value(n)
This is the standard portfolio weight calculation used in modern portfolio theory (Markowitz, 1952, Journal of Finance).
Why portfolio allocation matters
- Concentration risk: a single asset exceeding 50-70% of your portfolio amplifies gains but also losses.
- Correlation: some altcoins move closely with Bitcoin; true diversification requires assets with lower correlation.
- Rebalancing triggers: knowing your current weights lets you calculate how far you have drifted from target weights.
- Tax planning: understanding the proportion of each asset helps when deciding which positions to sell for tax-loss harvesting.
Portfolio allocation: frequently asked questions
What is portfolio allocation in crypto?
Portfolio allocation is the percentage of your total crypto portfolio held in each asset. If you hold $5,000 in Bitcoin and $5,000 in Ethereum in a $10,000 portfolio, each represents a 50% allocation. Tracking allocation helps you understand concentration risk and compare your actual holdings to your target weights.
How do I calculate the weight of each crypto holding?
Weight (%) = (Value of asset / Total portfolio value) x 100. For example, if Bitcoin is worth $15,000 and your total portfolio is $25,000, the Bitcoin allocation is (15,000 / 25,000) x 100 = 60%.
What is a well-diversified crypto portfolio?
There is no single standard for crypto diversification. Many investors hold a larger share in high-liquidity assets like Bitcoin and Ethereum (often 50-80%) and smaller amounts in mid- and small-cap tokens. The right allocation depends on your risk tolerance, investment horizon, and knowledge of each asset.
Should I rebalance my crypto portfolio?
Rebalancing involves selling assets that have grown above your target weight and buying those that have fallen below. How often to rebalance is a personal decision. Some investors rebalance quarterly; others rebalance when any asset drifts more than 5-10 percentage points from its target. Use the Crypto Portfolio Rebalancing Calculator for rebalancing amounts.
Does this calculator fetch live prices?
No. You enter the current value of each holding manually. This ensures accuracy regardless of the exchange or pricing source you use, and means you can use any fiat currency by entering values in a consistent unit.
