Funding cost calculator
Project funding paid or received across explicit settlements, or model a matched spot-long and linear futures-short cash-and-carry scenario.
Inputs
The starting values are a hypothetical example. Replace them with your own.
Result
Hypothetical example result.
- Signed cost per settlement
- 1 quote
- Signed cost across entered settlements
- 3 quote
- Settlement count
- 3 settlements
- Entered settlement interval
- 8 hours
- Count × interval, for context
- 24 hours
- Positive cost means you pay; negative cost means you receive. A positive rate makes longs pay shorts. A negative rate reverses the direction.
- This projection holds notional and rate constant at every settlement. Enter the number of settlements at which your position is eligible. Partial intervals are not prorated.

Formula and worked example
Signed cost per settlement = notional × rate ÷ 100 for a long. A short uses the opposite sign. Total signed cost = cost per settlement × the entered whole-number settlement count.
The interval describes the entered rate and gives timing context. Holding for part of an interval does not automatically create part of a funding payment. Eligibility and settlement times depend on the venue and contract.
Hypothetical example: a 10,000-unit long, 0.01% per 8-hour interval, and 3 eligible settlements. Cost is 1 per settlement and 3 in total. At the same positive rate, a short receives 3. The projection assumes a constant notional and rate.

Cash-and-carry scenario
Compare a spot long and a linear futures short, with explicit signed funding receipts and total costs. This is an entered scenario, not an execution or convergence guarantee.
Inputs
Hypothetical example. Replace these inputs with your own.
Result
Calculation result
Example result
- Net scenario result
- 2.32 quote
- Spot long result before costs
- 10 quote
- Linear short result before costs
- -5 quote
- Signed funding receipt for the short
- 0.32 quote
- Total entered costs
- 3 quote
- Entry futures minus spot
- 5 quote/unit
- Exit futures minus spot
- 0 quote/unit
- Net / spot acquisition value
- 2.315 %
- Spot long plus a matched-quantity linear futures short. Enter both exit prices; convergence is not assumed.
- Positive funding is received by this modeled short; negative funding is paid. The rate and entry futures notional stay constant across your entered eligible settlements.
- Trading, borrowing and other costs are entered totals in one quote currency. This excludes inverse contracts, changing position size, margin/liquidation, execution slippage beyond entered prices, tax and automatic rate data.
- Return uses spot acquisition value only. It is not annualized, leveraged margin ROI or a guarantee that the trade can be executed.

Formula and worked example
Spot result = q × (spot exit − spot entry); linear short result = q × (futures entry − futures exit). Funding receipt = q × futures entry × signed rate / 100 × settlements. Net subtracts all entered costs. Funding uses constant entry notional.
Hypothetical example: one unit bought spot at 100 and shorted at 105, with both exits at 110, gives +10 spot and −5 futures. Three 0.1% funding receipts total 0.315. Trading costs of 2 and borrowing costs of 1 leave a 2.315 result. No inverse futures, liquidation/margin estimate, annualized return or automatic rates are implied.
These estimates use bounded decimal arithmetic. They are scenario calculations, not trading instructions or forecasts.
