The Crypto Portfolio Calculator gives you an instant snapshot of your total portfolio value across all your coin holdings. Add as many cryptocurrencies as you own — Bitcoin, Ethereum, Solana, BNB, or any altcoin — enter your quantity and current price, and see your total portfolio value and allocation percentages in seconds.
Diversification is a core principle of portfolio management. The calculator's visual breakdown shows what percentage of your total portfolio each coin represents, helping you identify over-concentration in a single asset.
Most financial advisors recommend keeping crypto as 1–10% of a total investment portfolio. Within that crypto allocation, Bitcoin and Ethereum typically form the core holding (50–70%), with smaller allocations to higher-risk altcoins.
Portfolio Value Formula
Total Value = Σ (Coin Holdings × Current Price per Coin)
Allocation % = (Coin Value ÷ Total Portfolio Value) × 100
Sum the value of each individual coin position to get the total portfolio value. Allocation % shows your concentration in each asset.
You hold 0.5 BTC ($30,000), 5 ETH ($1,800/ETH), and 100 SOL ($80/SOL).
Result: Total portfolio = $32,000 (BTC: 46.9%, ETH: 28.1%, SOL: 25%)
No. Everything runs entirely in your browser. No data is sent to any server or stored anywhere.
A common approach: 50–60% BTC, 20–30% ETH, 10–20% large-cap alts (SOL, BNB, ADA), and a small allocation (5–10%) to higher-risk small-caps if you have conviction.
Most financial advisors recommend allocating no more than 5–10% of your total investment portfolio to crypto due to its volatility.
Portfolio ROI = (Current Total Value − Total Amount Invested) / Total Amount Invested × 100. Track your cost basis carefully for accurate ROI and tax reporting.
