About this calculator
Portfolio value is the sum of each asset's quantity multiplied by its current market price. For a BTC and ETH portfolio, the formula is: Portfolio Value = (btcAmount × btcPrice) + (ethAmount × ethPrice). This is a straightforward linear valuation — no compounding or time dimension is involved. The key variable is always the live market price, which fluctuates continuously, so the calculated value is only accurate at the moment of calculation. Diversifying across assets means your portfolio value is driven by the weighted movement of each coin. If BTC rises 10% but ETH falls 5%, the net effect depends on how much of each you hold. This calculator can be extended mentally to any number of assets by applying the same price × quantity logic to each additional holding.
How to use
Suppose you hold 0.75 BTC and 4.5 ETH. BTC is currently trading at $62,000 and ETH at $3,200. BTC Value = 0.75 × 62,000 = $46,500 ETH Value = 4.5 × 3,200 = $14,400 Total Portfolio Value = $46,500 + $14,400 = $60,900 Your portfolio is worth $60,900 at current prices. BTC represents 76.4% of the total and ETH the remaining 23.6%, giving you a sense of your concentration risk between the two assets.
Frequently asked questions
How often should I recalculate my crypto portfolio value?
Cryptocurrency prices move 24 hours a day, 7 days a week, so any static calculation is a snapshot rather than a live figure. For casual investors, checking once daily or weekly is usually sufficient to track overall performance. Active traders may monitor value continuously using exchange dashboards or portfolio apps. For tax purposes, you typically only need the value at specific dates — such as the date of a trade or the end of the tax year. Recalculating at the same time each day can help you build a consistent record of portfolio performance over time.
How do I calculate my crypto portfolio value if I hold more than just BTC and ETH?
This calculator covers BTC and ETH, but the underlying principle extends to any number of assets: multiply each coin's quantity by its current price and sum all the results. For larger portfolios with many coins, dedicated portfolio tracking tools like CoinGecko Portfolio, Delta, or Koinly aggregate live prices automatically. You can replicate the math in a spreadsheet by maintaining a column for quantity, a column for live price (via API or manual entry), and a calculated column for each asset's value. The grand total is simply the sum of all asset values.
What percentage of my crypto portfolio should I hold in Bitcoin versus altcoins?
There is no universally correct allocation — it depends on your risk tolerance, investment horizon, and conviction in specific projects. Bitcoin is generally considered the lowest-risk cryptocurrency due to its liquidity, market depth, and established track record, making it a common anchor holding (40–60% for many portfolios). Ethereum is widely regarded as the second-tier blue chip, often comprising 20–30%. Altcoins offer higher potential upside but also higher volatility and failure risk. A common heuristic is to hold the majority in BTC and ETH and limit speculative altcoins to a percentage you could afford to lose entirely. Rebalancing periodically helps maintain your intended allocation as prices shift.
