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.
This tool is essential for comparing trades across different assets, fee structures, or holding periods. The annualised return figure puts short and long-duration trades on the same scale for fair comparison.
The most expensive error is computing profit without accounting for trading fees. Fees on both entry and exit trades reduce net profit — and at scale, they represent a significant portion of gross gains. Always input accurate fee rates.
A trader holds a position that has doubled from the entry price and wants to know the exact net proceeds after the platform's 0.15% trading fee and an estimated 20% capital gains tax rate. The calculator returns the exact take-home figure — not the gross gain that the exchange UI displays.
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 (
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.
