About this calculator

P2P arbitrage captures the price gap between two markets for the same asset. You spend fiat to buy USDT on the cheaper venue (plus its taker/P2P fee), then sell on the pricier venue (minus its fee). What's left after both fees is your real profit; margin % measures it against capital deployed. The raw spread ignores fees and shows the theoretical ceiling.

FAQ

How is P2P arbitrage profit calculated?

Profit = amount x sell price (after sell fee) - amount x buy price (after buy fee). Margin % divides that by the fiat you spent.

What spread do I need to be profitable?

Enough to cover both fees plus transfer costs. If combined fees are 0.5%, the spread must exceed 0.5% before you net anything.

Is crypto arbitrage risk-free?

No. Prices move while you transfer, order books have limited depth, and settlement takes time. Treat the output as a best-case estimate.
