How to Use This Calculator

4 steps

1

Choose how you bought

Pick “Coins bought” if you know the quantity of coins you hold, or “Amount invested ($)” if you only know the total dollars you spent. The calculator converts an invested amount into coins using your buy price and buy fee.

2

Enter your buy and sell prices

Type the unit price you paid per coin and the price you sold at (or expect to sell at). Then set your fee type — a percent rate per trade (typical on exchanges) or a flat dollar fee — and the buy and sell fee for each leg.

3

Read your profit, ROI, and break-even

The result card shows your dollar profit or loss, ROI %, cost basis, net proceeds, total fees, and the break-even price that cancels both fees. Open the Break-Even tab for a sell-price sensitivity table, or Multi-Buy Average to combine several buys into one position.

4

Run scenarios and share

Adjust the sell price to see how your return changes, or use a preset for a realistic starting point. The Share button copies a link that restores your inputs; CSV exports the result for your records.

Formula & Methodology

5 formulas

Coins from an invested amount (percent fee)

coins = (invested ÷ (1 + buyFee%)) ÷ buyPrice

When you enter a total dollar amount, the buy fee is charged on the trade value, so the trade value is invested ÷ (1 + fee), and coins is that trade value divided by the unit buy price. With a flat fee, trade value = invested − flatFee.

Cost basis

costBasis = tradeValue + buyFee

Your cost basis is the all-in cash you spent to acquire the coins: the trade value plus the buy-side fee. In invested mode the cost basis equals the amount you entered.

Net proceeds and profit

netProceeds = coins × sellPrice − sellFee; profit = netProceeds − costBasis

Gross proceeds are coins times the sell price. Subtract the sell fee to get net proceeds, then subtract your cost basis to get profit or loss in dollars.

Return on investment (ROI)

ROI% = (profit ÷ costBasis) × 100

ROI expresses your profit as a percentage of what you put in. A 50% ROI means you ended with 1.5× your cost basis after fees.

Break-even sell price

breakEven = costBasis ÷ (coins × (1 − sellFee%))

The sell price at which net proceeds exactly equal your cost basis, so profit is zero. Because cost basis already includes the buy fee, this break-even covers both legs of fees. With a flat sell fee it becomes (costBasis + flatFee) ÷ coins.

Methodology

Profit, ROI, total fees, and break-even are derived from standard trade arithmetic: cost basis = coins × buy price + buy fee; net proceeds = coins × sell price − sell fee; profit = net proceeds − cost basis; ROI = profit ÷ cost basis. Fees are applied per side as either a percentage of the trade value or a flat dollar amount, and the break-even price solves net proceeds = cost basis so it covers both fee legs. The math is unit-tested against worked examples in tests/calculators/crypto-profit.test.js.

Assumption: Buy and sell prices, coin quantities, and fee rates are supplied by the user; the calculator does not fetch live market prices.

Assumption: A single fee rate is applied per side — if an order filled across maker and taker tiers, enter a blended rate.

Assumption: Coin quantities are kept at full floating-point precision and rounded only for display, so fractional-coin amounts compute accurately.

Limitations & guidance

This is a profit and break-even estimate, not a tax calculation. It does not determine capital-gains tax, which depends on holding period, jurisdiction, and cost-basis method (FIFO, specific-ID, etc.).

It does not account for slippage, spread, network/withdrawal fees, staking or interest, or price changes between when you read a quote and when an order fills.

Crypto prices are highly volatile; a computed result reflects only the prices you enter and is not a prediction or a recommendation to buy or sell.

Professional guidance: This calculator is for educational and planning purposes only and is not financial, investment, or tax advice. Cryptocurrency is volatile and you can lose money. Consult a licensed financial advisor or tax professional before making investment or tax decisions.

Glossary

Key Terms Explained

10 terms

Cost basis The total cash you spent to acquire your coins, including the buy-side exchange fee. Profit is measured against this number, and it is also the starting point for capital-gains tax.

Net proceeds The dollars you actually receive when you sell — gross sale value (coins × sell price) minus the sell-side fee.

Profit / loss (P/L) Net proceeds minus cost basis. A positive number is a realized gain; a negative number is a realized loss. Until you sell, gains are 'unrealized' and can still change.

ROI (return on investment) Profit divided by cost basis, expressed as a percent. It normalizes profit so you can compare trades of different sizes.

Break-even price The sell price at which your P/L is exactly zero after both the buy and sell fees. Selling above it is a gain; below it is a loss.

Exchange fee What a trading platform charges to execute a trade — usually a percentage of the trade value (a 'maker' or 'taker' rate), sometimes a flat amount. Fees apply on both the buy and the sell.

Maker / taker fee Two common percentage fee tiers. A 'maker' adds liquidity with a limit order and usually pays a lower rate; a 'taker' removes liquidity with a market order and usually pays more. This calculator uses one rate per side — enter whichever applies to your order.

Dollar-cost averaging (DCA) Buying a fixed dollar amount (or fixed quantity) at intervals regardless of price, which spreads your entry across several prices. The Multi-Buy Average tab combines those buys into one weighted-average cost.

Weighted-average cost Your blended buy price across multiple lots: total dollars spent on coins divided by total coins. The 'all-in' version also folds in buy fees.

Realized vs. unrealized gain A gain is 'unrealized' while you still hold the coins and only becomes 'realized' — and generally taxable — when you sell or trade them.

Scenarios

Real-World Examples

3 worked examples

🟢

Single buy, clean gain

0.5 BTC at $40,000, sold at $62,000, 0.5% fee each side

Coins bought 0.5 Buy price $40,000 Sell price $62,000 Fee (each side) 0.5%

Cost basis is 0.5 × $40,000 = $20,000 plus a $100 buy fee = $20,100. Gross proceeds are 0.5 × $62,000 = $31,000; the $155 sell fee leaves $30,845 net. Profit is $30,845 − $20,100 = $10,745, an ROI of about 53.5%. The $255 in fees shaved roughly 1.3% off the cost basis, and you would have broken even at about $40,402 per coin.

🔴

A loss after a drawdown

5 ETH at $3,000, sold at $2,100, 0.5% fee each side

Coins bought 5 Buy price $3,000 Sell price $2,100 Fee (each side) 0.5%

Cost basis is 5 × $3,000 = $15,000 plus $75 = $15,075. Net proceeds are 5 × $2,100 = $10,500 minus a $52.50 sell fee = $10,447.50. The loss is about −$4,628 (roughly −30.7% ROI). Note the break-even price of about $3,030 sits slightly above your $3,000 buy price — that gap is the fee drag you must overcome just to get back to even.

💵

Invested-amount mode

$1,000 invested at $25,000/coin, price now $34,000, 0.5% fees

Amount invested $1,000 Buy price $25,000 Sell price $34,000 Fee (each side) 0.5%

Your $1,000 buys about 0.03980 coins after the 0.5% buy fee (trade value $995.02 ÷ $25,000). At $34,000 the position is worth about $1,353 gross; after the sell fee, net proceeds are about $1,346. That's roughly a $346 profit, or about a 34.6% ROI — a useful way to size a position when you think in dollars rather than coins.

Deep Dive

Understanding the Crypto Profit Calculator

3 chapters · 5 min read

This calculator turns a crypto buy and sell into the numbers that actually matter: your dollar profit or loss, your percentage return, the fees you paid, and the price you need to break even. It works for a single trade or a position built from several buys, and it always accounts for exchange fees on both legs.

How the Crypto Profit Calculator works

The engine is deliberately simple and transparent. Your cost basis is the all-in cash you spent to acquire your coins — the trade value plus the buy fee. Your net proceeds are what you receive on the sell — gross sale value minus the sell fee. Profit is just net proceeds minus cost basis, and ROI is that profit as a percentage of cost basis.

There are two ways to enter a buy. In coins-bought mode you name the quantity and the unit price, and the buy fee is added on top. In amount-invested mode you name the total dollars you spent; the calculator backs out the trade value (invested ÷ (1 + fee%) for a percentage fee) and derives the coin quantity. Both modes converge on the same cost-basis math.

Why fees and break-even matter more than people think

Crypto exchanges typically charge a percentage fee on every trade, often around 0.1%–0.6% per side, and you pay it twice — once buying and once selling. Those two fees mean the price has to rise above your purchase price just to get back to even. The calculator's break-even price bakes both fees into a single number, so you can see exactly how far the market has to move before you are in profit.

The Break-Even tab adds a sensitivity table: it shows your profit and ROI at sell prices from half to double your buy price, which makes the asymmetry of gains and losses concrete. The Multi-Buy Average tab does the same job for a dollar-cost-averaged position, blending several buys into one weighted-average cost.

Limits, taxes, and what this tool does not do

This is a planning and record-keeping aid, not tax or investment advice. It does not pull live prices, track your wallet, or compute the exact capital-gains tax you owe — that depends on your holding period, your country's rules, cost-basis method (FIFO, specific-ID, and so on), and any wash-sale or income-classification considerations. It also assumes a single fee rate per side; if your order filled across maker and taker tiers, use a blended rate. For realized gains and tax filing, keep your own transaction records and consult a qualified tax professional.

Questions

Frequently Asked Questions

7 questions

How is crypto profit calculated?+

Profit equals your net proceeds minus your cost basis. Net proceeds are the coins you hold times the sell price, minus the sell fee. Cost basis is what you paid for the coins plus the buy fee. ROI then expresses that profit as a percentage of your cost basis.

Does the calculator include exchange fees?+

Yes. You can enter a buy fee and a sell fee as either a percentage of each trade (the default, matching most exchanges) or a flat dollar amount. Both fees are folded into your cost basis, net proceeds, total fees, and break-even price.

What is the break-even price?+

It's the sell price at which your profit is exactly zero after both fees. Because the buy fee is already in your cost basis, the break-even is always a little above your buy price — that gap is the round-trip fee you have to overcome before you make any money.

What's the difference between 'coins bought' and 'amount invested' mode?+

Use 'coins bought' when you know the quantity of coins you hold. Use 'amount invested' when you only know the total dollars you spent — the calculator converts that into a coin quantity using your buy price and buy fee, which is handy because exchanges often let you buy a dollar amount rather than a round number of coins.

Can I model dollar-cost averaging or several buys?+

Yes — the Multi-Buy Average tab lets you enter each buy (coins, price, and fee) and computes your weighted-average cost, total invested, and the current profit or loss at a single sell price. It's the right tab when you scaled into a position over time.

Are these gains taxable?+

In most countries, selling or trading crypto is a taxable event and realized gains are subject to capital-gains tax, while the cost basis you see here is the starting point for that calculation. This tool does not compute your tax — your rate depends on your holding period, jurisdiction, and cost-basis method. Treat the result as an estimate and consult a tax professional.

Does it use live crypto prices?+

No. You enter the buy and sell prices yourself, so the result is a deterministic calculation you control. That makes it equally useful for reviewing a past trade or planning a hypothetical one — just type the prices you want to test.
