Hyperliquid builder fee calculator
Turn eligible trading volume into an earnings estimate. Compare Floatout plans, include referral payouts and see how long activation takes to pay back.
When does activation make sense?
Estimate earnings from your own activity assumptions. Free sites earn no owner fees before activation.
Use only volume that generates your builder fee. Prediction volume here means eligible sell-order volume, not headline market volume. Settlement fees are excluded. 1 bp = 0.01%.
Average referral allocation includes trades without referrals. Kickbacks come out of that allocation, not an additional charge to you.

Illustrative estimate, not a revenue forecast. Assumes constant eligible activity, rates and referral mix. Payback uses net earnings after the costs you enter. Taxes and unentered expenses are excluded. Actual earnings depend on collected builder fees. Free-period fees are not a claimable balance or activation credit.
How the math works
Builder fee = eligible volume × fee rate. Rates are in basis points, and 1 bp is 0.01%. At 2.5 bp, $1 million of eligible volume pays $250 in gross builder fees.
Hyperliquid sets the ceiling:
- Perps: up to 0.1% (10 bp), on buys and sells.
- Spot: up to 1% (100 bp), on sells only.
- Outcome markets: Floatout charges the builder fee on sells.
- Trader approval: each trader signs a maximum fee for your builder address. Your fee cannot go above it.
See Hyperliquid's builder code docs for the source, or our guide to how Hyperliquid builder codes work.
Gross vs net
Gross is what traders pay your builder code. Net is what you keep after three things come out:
- Floatout's platform share, set by your plan. Compare plans.
- Referral commissions to partners, and any trader kickbacks paid out of them.
- Your own costs: promotion, moderation and support.
Annual figures assume twelve identical months. On the free plan builder fees go to Floatout, so there is nothing to keep until you activate.
Use the right volume
Enter activity routed through your frontend that actually pays a builder fee. For prediction markets that means eligible sell volume. Headline market volume, buy orders and settlement proceeds are a different number. The prediction market fee guide walks through it.

Frequently asked questions
What is the maximum builder fee on Hyperliquid?
0.1% (10 bp) on perps and 1% (100 bp) on spot. Each trader also approves a maximum fee for your builder address, and an order cannot charge more than that. Traders can revoke the approval at any time.
What unit is the builder fee in?
This calculator takes basis points, where 1 bp is 0.01%. Hyperliquid's order API uses tenths of a basis point, so a fee value of 10 there means 1 bp.
Do builder fees apply to both sides of a trade?
On perps, yes: buys and sells both pay it. On spot it applies to sells only, because builder fees are charged in the quote asset. On HIP-4 outcome markets Floatout charges it on sells.
Is the result a revenue forecast?
No. It multiplies the volume and rates you enter. Real volume depends on your community and changes month to month.
