Crypto Profit Calculator
100% private — runs on your device, never uploaded. Works offline once loaded.
See the real profit or loss on a crypto trade after buy and sell fees, along with your ROI percentage, total fees paid and break-even price. Enter a coin quantity or the dollar amount you invested. Everything runs in your browser.
How profit, ROI and fees are computed
The tool starts from your position. If you enter a quantity of coins, it multiplies that by the buy price to get the gross purchase amount. If you instead enter the dollar amount invested, it divides that by the buy price to derive the quantity. Either way it arrives at the same set of numbers.
The buy fee is charged on the gross purchase, so your total cost is the purchase plus that fee. On the way out, the gross sale is your quantity times the sell price, and the sell fee is deducted from it to give net proceeds. Profit is simply net proceeds minus total cost, and ROI is that profit divided by total cost, as a percentage.
Why fees deserve close attention
Exchange fees look small as a percentage but they are charged twice, once on entry and once on exit, and they scale with the size of your trade rather than your profit. On a round trip, a 0.1 percent fee each way quietly removes roughly 0.2 percent of your traded value before the price has moved at all.
For active traders the cumulative drag is far larger than a single trade suggests. That is why the calculator surfaces total fees as their own figure and computes a break-even sell price: the price at which your net proceeds exactly equal your total cost, so you neither gain nor lose after fees.
Quantity versus amount invested
Both entry modes describe the same trade from different angles, and it helps to know which the tool assumes.
- Quantity mode: you know how many coins you hold, and the tool derives the dollar cost from the buy price.
- Amount-invested mode: you know the gross dollar figure you spent on the coin, and the tool derives the quantity by dividing by the buy price; the buy fee is then added on top of that amount.
- In both modes ROI is measured against total cost including the buy fee, so the two approaches agree on the final profit and percentage return.
What this does and does not account for
The calculator models a single buy-and-sell round trip with percentage fees on each side, which covers the vast majority of spot trades. It does not model flat withdrawal fees, network gas costs, spread between bid and ask, funding rates on leverage, or the tax owed on a realised gain. It also assumes you sell your entire position at one price. For dollar-cost-averaged entries or partial exits you would need to average your prices first, and you should treat the profit shown as pre-tax.
Frequently asked questions
What is the break-even sell price?
It is the sell price at which your proceeds after the sell fee exactly cover your total cost including the buy fee. Sell above it and you profit; sell below it and you lose money, even if the price is above your buy price.
Does 'amount invested' include the buy fee?
No. Amount invested is treated as the gross amount spent on the coin itself. The buy fee is then calculated on that amount and added to determine your total cost.
Can it handle a loss?
Yes. If your sell price and fees produce net proceeds below your total cost, the profit and ROI are shown as negative values in red.
Why is my ROI lower than the raw price gain?
Because fees are deducted on both the buy and the sell. A 50 percent move in price becomes a slightly smaller percentage return once entry and exit fees are subtracted from the result.
Does it work for any coin?
Yes. The math is currency-agnostic. Enter the buy and sell prices in whatever currency you traded, and the outputs are in that same currency.
Is the profit figure after tax?
No. It is a pre-tax realised profit. Capital-gains rules vary widely by country, so apply your local tax treatment to the profit shown.
