A positive rate normally means longs pay shorts. A negative rate normally means shorts pay longs.

A positive rate normally means longs pay shorts. A negative rate reverses the payment direction.
Funding moves cash between longs and shorts
Perpetual contracts do not expire. Exchanges use periodic funding payments to encourage the contract price toward its index. The rate sign determines the payer; your position notional determines the amount.
Use notional value
Funding is usually applied to position notional, not only to the margin posted for the trade.
Count settlements
A position must still be open at the exchange settlement time for that funding event to apply.
From one settlement to total carry cost
Calcoring treats a positive result as funding received and a negative result as funding paid. The annualized figure extends the current rate mechanically; it is not a forecast that the rate will stay unchanged.

The calculator reads public perpetual-market data from Binance, OKX, Bybit, and Hyperliquid. It keeps every field editable because rates, caps, intervals, and settlement rules can change by symbol and market conditions.
- The displayed rate may change before the next funding timestamp.
- Exchange interfaces may distinguish estimated, current-period, and settled rates.
- Hyperliquid settles hourly; many major USDT perpetuals on centralized exchanges commonly use longer intervals.
- Your actual account statement remains the authoritative record of funding paid or received.
Holding a $10,000 BTC long through three settlements
At a positive 0.01% rate per 8-hour settlement, a $10,000 long pays $1 each time. Three unchanged settlements produce a $3 cost. With $1,000 margin, that is a −0.30% funding impact on equity before price PnL and trading fees.

Funding-rate questions
Does positive funding always mean longs pay?
That is the common convention for linear perpetuals, but verify the contract and exchange display. Calcoring makes the side and rate sign explicit so you can model either direction.
Is funding charged on margin or notional?
It is generally based on position notional or position value. Leverage therefore magnifies funding as a percentage of the margin used.
Do I pay funding if I close before settlement?
Normally no for that event. Funding applies to positions open at the settlement timestamp, although exact processing rules belong to the exchange.
Why can the live rate differ from the final payment?
The displayed rate can update during the funding period. Position size, mark value, rate caps, and the final settled rate can all change before settlement.
Is the annualized funding rate a forecast?
No. It only repeats the current per-interval rate across one year to make rates easier to compare. Real funding is variable and can change sign.
