Ethereum profit is the net sale proceeds minus the cost basis, where buying fees add to the basis and selling fees come off the proceeds. Buying 2 ETH at $1,500 with a $30 fee and selling at $2,000 with a $40 fee gives $3,960 minus $3,030, a $930 gain or 30.69% on the money put in.

About this tool

Anyone who has bought ether on an exchange and is weighing a sale wants one figure first: what is left after fees. This calculator takes the coins held, either as an ETH quantity or as the dollars you spent, plus the purchase price, the selling price and the fees on each side. It returns the profit or loss, the percentage return on the cost basis, net proceeds, total fees and the price per coin at which the trade breaks even. Gas costs paid in ETH should be entered at their dollar value on the day. The result is a pre-tax figure for a single purchase lot; it does not match lots bought at several prices or apply any tax rate.

How to use it

Choose how to describe the position
Pick ETH quantity if you know the coins bought, or Amount invested to enter the dollars spent.
Enter the purchase
Type the price per ETH you paid and any exchange commission or gas paid on the buy.
Enter the sale
Add the actual or target selling price per ETH and the fees charged on the sale.
Read the result
Profit or loss updates as you type, with return, break-even price and the working underneath.

Examples

2 ETH bought at $1,500, sold at $2,000

Enter the position as: ETH quantity
ETH bought: 2
Purchase price per ETH: 1500
Purchase fees: 30
Selling price per ETH: 2000
Selling fees: 40

Result Profit or loss: 930.00
Return on cost basis: 30.69%
ETH held: 2
Cost basis incl. fees: 3,030
Net sale proceeds: 3,960
Break-even sell price: 1,535
Total fees: 70

ETH held = 2
Cost basis = 1500 x 2 + 30 fee = 3030
Net proceeds = 2000 x 2 – 40 fee = 3960
Profit = 3960 – 3030 = 930
Return = 930 / 3030 x 100 = 30.69%
Break-even sell price = (3030 + 40) / 2 = 1535

A $30 buy fee lifts the basis to $3,030 and a $40 sell fee trims proceeds to $3,960, leaving a $930 gain.

$1,000 put in at $2,500 per ETH

Enter the position as: Amount invested
Amount invested: 1000
Purchase price per ETH: 2500
Selling price per ETH: 3000

Result Profit or loss: 200.00
Return on cost basis: 20%
ETH held: 0.4
Cost basis incl. fees: 1,000
Net sale proceeds: 1,200
Break-even sell price: 2,500
Total fees: 0

ETH held = 0.4
Cost basis = 2500 x 0.4 + 0 fee = 1000
Net proceeds = 3000 x 0.4 – 0 fee = 1200
Profit = 1200 – 1000 = 200
Return = 200 / 1000 x 100 = 20%
Break-even sell price = (1000 + 0) / 0.4 = 2500

$1,000 buys 0.4 ETH; at $3,000 that position is worth $1,200, a 20% gain before any fees.

1 ETH bought at $3,000, sold at $2,500

Enter the position as: ETH quantity
ETH bought: 1
Purchase price per ETH: 3000
Selling price per ETH: 2500

Result Profit or loss: -500.00
Return on cost basis: -16.67%
ETH held: 1
Cost basis incl. fees: 3,000
Net sale proceeds: 2,500
Break-even sell price: 3,000
Total fees: 0

ETH held = 1
Cost basis = 3000 x 1 + 0 fee = 3000
Net proceeds = 2500 x 1 – 0 fee = 2500
Profit = 2500 – 3000 = -500
Return = -500 / 3000 x 100 = -16.67%
Break-even sell price = (3000 + 0) / 1 = 3000

The sale is $500 below cost, a loss of 16.67% on the basis.

How it is calculated

Profit = (S × Q − Fs) − (B × Q + Fb); Return = Profit ÷ (B × Q + Fb) × 100; Break-even = (B × Q + Fb + Fs) ÷ Q

Q: ETH held (or amount invested ÷ B)
B: purchase price per ETH
S: selling price per ETH
Fb: fees paid when buying
Fs: fees paid when selling

The cost basis is what you paid for the coins plus the costs of acquiring them, and the amount realized is the sale value less the costs of selling, the same treatment the IRS describes for digital assets. Profit is the difference. Return divides that profit by the basis, so a fee-heavy small trade shows a lower percentage than the price move alone. The break-even price is the selling price per coin that would bring profit to exactly zero after both fees.

When not to use it

Several purchases at different prices need a lot-by-lot or average-cost method instead of one buy price.
Staking rewards are income when received and need their own basis.
It does not estimate the tax owed on the gain.

Common mistakes

Leaving out gas paid on the buy, which understates the cost basis.
Entering a fee in ETH instead of its dollar value at the time.
Comparing the price change percentage with the return after fees.

Frequently asked questions

Do exchange fees count toward my cost basis?

Yes. Under IRS guidance for digital assets, fees and commissions paid to acquire the coins are part of the basis, and fees paid to sell reduce the amount realized. Entering both makes the profit here line up with how a gain is reported.

How is the break-even price worked out?

It adds the purchase cost, the buying fee and the selling fee, then divides by the ETH held. With 2 ETH bought at $1,500, a $30 buy fee and a $40 sell fee, the break-even is $3,070 ÷ 2 = $1,535 per coin.

What if I only know how many dollars I put in?

Switch the first control to Amount invested. The calculator divides that sum by the purchase price to get the ETH held, so $1,000 at $2,500 per coin becomes 0.4 ETH.

Why is my return lower than the price increase?

The price change ignores fees, while the return here is profit after both fees divided by a basis that includes the buying fee. On small trades a fixed gas cost can take several percentage points off.

Can I use it for a sale I have not made yet?

Yes. Enter a target selling price to see the profit it would produce, or read the break-even figure to see the lowest price that avoids a loss after fees.

Does it handle a loss?

A selling price below break-even returns a negative figure and a warning. Buying 1 ETH at $3,000 and selling at $2,500 with no fees shows a $500 loss, or −16.67% of the basis.
