Spread rebate vs fixed per-lot rebate: which to choose?

Rebates are usually priced two ways: as a percentage of the spread, or as a fixed amount per lot. Understanding the difference helps you compare providers.

Percentage of spread

Rebate = spread cost x rebate rate. The larger the spread, the larger the rebate; it often pairs with raw-spread + commission accounts and suits instruments whose spread varies (e.g. gold).

Fixed amount per lot

Rebate = amount per lot x lots. Simple and predictable, easy to plan around; suits traders who stick to a few instruments and value certainty.

How to compare

• Estimate your monthly rebate under both models using your typical lot size and number of trades.
• Watch the spread itself: low spread + high rebate rate usually beats high spread + low rebate.
• Note the payout cycle and thresholds (daily / weekly / monthly).

Use the rebate calculator for a per-lot estimate, then compare against a % model. See the INFINOX rebate page.
