Aster funding calculator
Estimate long or short holding costs with editable funding rates, intervals and position notional.
What this estimate includes
A constant-rate, constant-notional linear estimate. Actual funding occurs at discrete settlements and can change. Negative net funding means received, not trading profit. Use the market explorer to inspect current rates and intervals.
The formula
Estimated funding = notional × rate ÷ 100 × holding hours ÷ interval hours. Reverse the sign for shorts. Positive values are paid; negative values are received. Fractional intervals are an estimate, not a settlement count.
