Funding-rate carry calculator
In short
What an 0.01%/8h really costs.
Interactive: funding-rate carry calculatorMedium
Translate a perp funding rate into annualised yield — what a delta-neutral basis trade (long spot, short perp) would collect while the rate persists.

- Compounded APY

Funding flips sign and mean-reverts violently; annualised numbers assume persistence that rarely lasts. Exchange counterparty risk is the strategy's true price — FTX taught that lesson at scale.
The idea behind it
This calculator belongs to Digital Assets, where the mechanism it computes is explained step by step, with the formula, what each input means and where the simple model stops being right. Everything is computed in your browser; nothing you type is sent anywhere.
Instruments it applies to
- Crypto Spot — Bearer assets on public ledgers — a new asset class still arguing about what it is.
- Perpetual Future — Crypto's native derivative: a future that never expires, tethered to spot by a funding rate.
- Crypto Option — Calls and puts on bitcoin and ether — vanilla mechanics, triple-digit volatility.
- Crypto ETP / ETF — Crypto without the keys: bitcoin and ether wrapped into ordinary brokerage-account securities.
- Stablecoin — A dollar that settles like crypto: the token that pegs itself to fiat and quietly became the plumbing of the entire digital-asset market.
- Staking & Liquid Staking — Earning the blockchain's own interest rate — and the token that made locked collateral liquid, basis risk included.
- Tokenised Treasury — A government bond fund with a blockchain wrapper. The yield comes from the bills; the token contributes settlement speed and a new set of failure points.
- CBDC — Central bank money in digital form, held directly by the public. Not a cryptoasset in any meaningful sense — and potentially the largest change to bank funding in a century.
