What the crypto arbitrage calculator does
Crypto arbitrage means buying a coin where it is cheaper and selling it where it is dearer — on two exchanges, or around a loop of three trading pairs on one exchange. The quoted price gap is rarely the profit: trading fees on both sides, the withdrawal or network fee to move the coins, slippage and taxes all come out first. This crypto arbitrage calculator takes every one of those numbers from you and shows the profit that is actually left, plus the break-even spread you need before a gap is worth chasing.
Two modes are included. Two exchanges buys on exchange A, sends the coins and sells on exchange B. Triangular converts a starting currency through two others and back, for example USDT → BTC → ETH → USDT, with a fee on every leg. Indian traders can switch on the 1% TDS on the sale to see how much cash is held back.
Nothing is fetched: exchanges change their fees, prices move while coins are in transit, and tax rules change. Type current figures from each exchange. The result is arithmetic on your inputs, not trading or tax advice.
How to use the Crypto Arbitrage Calculator
- Choose Two exchanges or Triangular.
- Two exchanges: enter the amount you spend, the buy price and fee on A, the sell price and fee on B, and the withdrawal fee in coins.
- Triangular: enter the starting amount, the three currencies and, for each leg, the market price, whether you buy or sell the base currency, and the fee.
- Add slippage if your orders will move the book, and other fixed costs such as bank fees.
- In India, tick TDS to see the 1% held back on the sale. Read the profit, the break-even spread and copy the result.
Crypto Arbitrage Calculator features
Fee-adjusted profit
Buy fee, sell fee, coin network fee, slippage and fixed costs all come out before the profit.
Break-even spread
The sell price — and the percentage gap — at which the trade exactly pays for itself.
Triangular loops
Three legs with their own prices, directions and fees, plus the same loop run the other way.
India TDS
1% held back on the sale consideration, shown as cash held back rather than as a cost.
Any currency
USDT, US dollars, rupees, pounds or euros as the quote currency.
How the profit is worked out
Two exchanges: coins bought = amount × (1 − buy fee) ÷ (buy price × (1 + slippage)). The coins that arrive are that minus the network fee. Proceeds = coins arriving × sell price × (1 − slippage) × (1 − sell fee), and profit = proceeds − amount − fixed costs. Triangular: each leg multiplies the amount by 1 ÷ price when you buy the base currency or by the price when you sell it, then takes off slippage and the fee.
Worked example: spend 10,000 USDT on BTC at 60,000 with a 0.1% fee: 0.1665 BTC. Withdrawing costs 0.0002 BTC, so 0.1663 BTC arrives. Selling at 60,600 brings 10,077.78, less a 0.1% fee = 10,067.70. The 1% quoted gap becomes a 67.70 USDT profit (0.68%); anything below a 0.32% gap would lose money. A triangular loop USDT → BTC (60,000) → ETH (0.05 BTC) → USDT (3,030) has a 1% gross edge; three 0.1% fees leave 1,006.97 from 1,000.
Tax: India’s 1% TDS and other countries
In India, the buyer — normally the exchange — deducts 1% TDS on the consideration for transferring a virtual digital asset under section 393(1), Table Sl. No. 8(vi) of the Income-tax Act, 2025 (formerly section 194S), in force from 1 April 2026; CBDT Circular 13 of 2022 says it is worked out after GST and exchange charges. It is a credit against your tax, so it reduces the cash you get now, not your profit. Separately, gains are taxed at 30% with no set-off of losses. Rules as of 24 October 2026; the rate is editable because it can change. In the US and UK each sale is a taxable disposal — see the crypto capital gains calculator and the TDS calculator for India’s other rates.
Why real arbitrage is harder than it looks
- Transfer time. A blockchain transfer can take minutes or longer, and the gap can close before the coins arrive.
- Depth. The quoted price is only for a small size; larger orders fill at worse prices (slippage).
- Withdrawal limits and fiat rails. Moving money back can be slow or costly, which is why gaps between countries persist.
- Triangular gaps vanish in milliseconds on liquid exchanges; most are taken by automated traders.
Crypto Arbitrage Calculator FAQ
How do you calculate crypto arbitrage profit?
Take the coins you buy after the buy fee, subtract the network fee, sell what arrives and subtract the sell fee, then subtract what you spent and any fixed costs. The crypto arbitrage calculator does each step and shows the break-even spread.
What spread do I need for crypto arbitrage to be profitable?
Enough to cover both trading fees, the withdrawal fee and slippage. With 0.1% fees on each side and a 0.0002 BTC withdrawal fee on 10,000 USDT, about 0.32%.
How does a triangular arbitrage calculator work?
It multiplies the starting amount through three exchange rates and three fees. If the product of the rates is above 1 by more than the fees, the loop makes a profit.
Is TDS deducted on crypto arbitrage in India?
Yes, 1% TDS applies to the sale consideration of a virtual digital asset. It is credited against your tax and can be refunded through your return if it is more than you owe.
Does this tool find arbitrage opportunities?
No. It fetches no prices. Type the prices and fees you see to check whether a gap is worth trading.
