Total Cost = (Buy Price × Qty) + Buy Fee + Spread + Network Fee. Net Revenue = (Sell Price × Qty) − Sell Fee − Withdrawal Fee. Net Profit = Net Revenue − Total Cost. The calculator runs all four expressions automatically and shows ROI as Net Profit ÷ Total Cost × 100.

Taker fees apply when you place a market order (or a limit order that fills immediately) — you take liquidity off the book. Maker fees apply when your limit order sits on the book until matched — you make liquidity. Maker fees are typically 30–50% lower. Switching from market to limit orders is the simplest way to cut crypto trading costs.

Yes — most jurisdictions (US, UK, Australia, EU) let you add network/gas fees and exchange trading fees to the cost basis of the asset. This reduces your taxable gain. Withdrawal fees on the sell side are similarly deductible from sale proceeds. Document them per-trade for clean tax reporting.

Break-Even Sell Price = (Total Cost + Withdrawal Fee) ÷ (Quantity × (1 − Sell Fee %)). It's the minimum sell price at which you recover every dollar spent including all fees that will be deducted on the sell side. Below break-even you lock in a loss; above it you start to profit.

On a 0.5% taker fee both sides, fees alone consume 1% of your trade value before any spread, gas, or withdrawal costs. On illiquid altcoins, the bid-ask spread can add another 0.5–2%. Total round-trip fee burden of 2–4% is common — meaning you need a 3–5% favorable price move just to break even.

Use limit (maker) orders not market orders, batch small withdrawals into fewer larger ones (network fees are flat), trade on chains with cheap gas (L2s, Solana, BSC) when feasible, and qualify for higher VIP tiers on your exchange via volume to unlock lower fee rates.
