Funding Cost Adds Up Over a Holding Period, So Plan for a Range
A funding rate quoted per 8-hour interval looks negligible on its own, but perpetual futures settle funding three times daily, and the rate itself resets every interval based on market conditions. It is not fixed for however long you hold the position. This tool asks you to specify an intended hold duration and projects total cumulative funding over that period, rather than showing only a single-interval snapshot that says nothing about a multi-day hold.
Why a Volatility Band Matters
Assuming today's funding rate holds perfectly constant for three days, a week, or longer is rarely realistic. Funding rates move with market sentiment and can shift quite a bit within a single holding period. The rate volatility band lets you model a plausible range around the current rate, producing a best case and worst case cumulative funding figure alongside the expected value, so you can see how sensitive your total cost is to funding drifting from where it sits today.
| Rate per 8h | Cumulative Over 3 Days (9 intervals) on $6,000 |
|---|---|
| 0.01% | +$5.40 |
| 0.01% with a 0.015% band | -$2.70 to +$13.50 |
| 0.05% | +$27.00 |
Break-Even Shift From Funding Alone
Beyond a raw dollar figure, the tool converts cumulative funding into a shifted break-even price. It shows how much further price needs to move in your favor to offset funding drag specifically, expressed as an actual price rather than a percentage. This number is meant to sit alongside the Trade Planner's fee-based break-even for a fuller picture of total holding cost. Fees are a one-time cost paid on entry and exit, while funding is an ongoing cost that grows the longer the position stays open.
Reading Net ROI Impact
Net ROI impact expresses cumulative funding as a percentage of position notional, making it easy to compare funding drag directly against your expected price move return on the same trade. A position targeting a 3% price move that's paying 0.5% in cumulative funding over the hold period has had roughly a sixth of its expected edge quietly eaten by funding, a cost that's invisible if you only watch price.
