What a funding pair earns, after costs.

Free funding rate arbitrage calculator: pick a coin and two perpetual venues, live funding rates and spreads fill in, and see daily earnings, costs, days to break even and net return after fees.

How it works

Short the perpetual on the venue that pays the higher funding rate and buy it on the venue that pays less. Each day at current rates the position earns the funding spread divided by 365, on the size of one leg. It pays for entry and exit once: fees for four fills, both venues' bid-ask spreads and slippage. Days to break even is those costs divided by one day of funding.

Costs per pair: 3 bps fee per fill (12 bps for both legs in and out), both venues' live bid-ask spreads, 2 bps slippage, all ×1.25 as a safety margin. Net edge covers one day at current rates, with no credit for basis.
