Surge fee and minimum

The Surge fee is 0.2% of the ADA side of every order, reduced by your staking tier. The minimum fee is 0.978 ADA per order.

How it is calculated

• Buy (ADA → token): 0.2% of the ADA you trade.

• Sell (token → ADA): 0.2% of the ADA you expect to receive.

• Your staking tier reduces the base rate. See Tiers and fee discounts.

• Surge charges the larger of the percentage fee or 0.978 ADA.

Why the minimum is 0.978 ADA

Cardano requires each transaction output to meet its minimum value. Surge uses 0.978 ADA as the minimum fee so the fee output meets that requirement.

Trade size	Percentage fee	Surge fee
1,000 ADA	2.00 ADA	2.00 ADA
489 ADA	0.978 ADA	0.978 ADA
100 ADA	0.20 ADA	0.978 ADA
20 ADA	0.04 ADA	0.978 ADA

The minimum applies to fee previews, required-balance panels, trade records, and analytics.

When your rate changes

Your rate is set when you create your account. If you subscribe to staking, Surge recalculates it every six hours from your staking snapshot. A tier change applies at the next snapshot.
