Crypto Profit Calculator

The Crypto Profit Calculator works out what a crypto trade actually made: enter the investment amount or the coin quantity, the buy and sell prices, and any trading fees (percentage or fixed), and it returns total coins, buy and sell costs, gross and net revenue, profit or loss, ROI, the break-even price, and a scenario table at 1.5x, 2x, 3x, and 5x the buy price. An optional tax rate shows the after-tax figure on profitable trades.

How It Works

$\text{Total buy cost}=\text{Coins}\times\text{Buy price}+\text{Buy fee}\qquad \text{Gross profit}=(\text{Coins}\times\text{Sell price}-\text{Sell fee})-\text{Total buy cost}$

Enter an investment amount and the calculator derives the coin quantity after the buy fee (investment minus fee, divided by buy price); enter coins directly and it skips that step. Tax applies only to positive gross profit, at the single rate you enter. Break-even price is total buy cost divided by total coins.

Parameters

| Input | Required | Meaning | |---|---|---| | Investment amount or coins | Yes | One of the two ways to size the position | | Buy price / sell price | Yes | Your entry and exit (or hypothetical exit) | | Buy / sell fee | No | Percentage or fixed amount, each side | | Tax rate | No | Applied to positive profit only | | Target price | No | Computes the net profit at that exit |

Worked example

Invest $1,000 at a buy price of$100 with no buy fee: you hold 10 coins. Sell at $120 with a 1$1,200, the fee is $12, net revenue is **$1,188**, gross profit is $188**, and ROI is **18.8$1,000 cost. Add a 20% tax rate and the tax is $37.60, net profit **$150.40, net ROI 15.04%. The break-even price is $100.00 on these inputs, and the scenario table prices the position's exits at$150 (profit about $488 after the same fee basis),$200 ($988),$300 ($1,988), and$500 ($3,988). Two structural lessons: the sell fee means the price must rise slightly more than intuition suggests before profit starts (the displayed break-even covers buy-side cost; the exit fee is recovered only above it), and ROI is computed on total cost including fees, the honest denominator most exchange interfaces omit when they show you a green percentage.

Fees, spread, and the costs the headline hides

Exchange fee inputs exist because crypto's visible price is not its transacted price. Beyond the explicit trading fee this calculator models, real round trips also pay the bid-ask spread (market orders cross it on both sides), slippage on thin pairs, network or withdrawal fees when moving coins off an exchange, and FX conversion on non-USD pairs. Each is individually small and collectively decisive for active strategies: a 0.5% all-in friction per round trip means a strategy must beat the market by that much per trade merely to stand still, which is why the calculator insists on fee fields rather than burying a zero-fee assumption. For a precise personal figure, add your known fixed costs (withdrawal, network) into the fixed fee fields rather than approximating them as percentages.

The tax field, and its limits

The model's tax is deliberately simple: one rate, applied to positive gross profit, no loss offsets. Real crypto taxation is jurisdiction-specific machinery: capital gains with holding-period distinctions (for example short versus long term in the US), cost-basis methods (FIFO, specific identification), wash-sale rules that for crypto have historically differed from securities in some jurisdictions and are changing, staking and airdrop income taxed on receipt, and loss harvesting rules. Use the field to reserve a sensible provision against a profitable exit (many traders set aside the tax estimate at sale time rather than discovering it at filing), and treat the output as a provision, not a return. For multi-lot positions, the Stock Average Calculator's lot method and a dedicated cost-basis record are the right companions; this calculator models one buy and one sell.

Frequently Asked Questions

Can I model a position I have not sold yet?

Yes: the sell price is any price you want to evaluate, including the current market price for an unrealized figure, or a hoped-for exit. The target price field exists for the same purpose and reports the after-tax profit at that specific exit without disturbing the main calculation.

Why is my ROI lower than the price increase percentage?

Because ROI divides by your total cost (price plus fees) and subtracts fees from the revenue, while the price-change figure the calculator also reports ((sell - buy) / buy) is the coin's move alone. The gap between the two is exactly your friction, quantified.

Does the calculator fetch live prices?

No. It computes from the prices you enter, which keeps it usable for historical trades, hypothetical exits, and coins no feed covers. Enter the current price yourself when you want a live-valuation estimate.
