Amazon's MCF credit caps at $50K.
Amazon rolled out MCF 2026 Preferred Pricing on January 15. You get a percentage discount on outbound fulfillment fees AND an FBA credit per unit shipped. The highest tier offers 15% off + $1 per unit back as FBA credit.
Most sellers are treating this as a stacked discount. They see "15% off + $1 back per unit" and calculate savings as if both scale infinitely with volume.
They don't.
The FBA credit has a hard cap at $50,000. The percentage discount does not. For high-volume operators, the credit runs out quickly while the discount keeps compounding.
Before you model your savings, you need to understand which track you're on.
There are two enrollment paths:
The 6-month program is for new MCF users or established FBA sellers testing MCF. If you shipped 100+ MCF units through the New Seller Incentive program after October 15, or you started using an MCF API integration, you're automatically enrolled. You get 15% off + $1 per unit for six months, capped at $50K in credits.
The 12-month program is volume-based and tiered. If you shipped between 1,200 and 23,000 MCF units in the past 12 weeks, you qualify. Your discount and credit scale with your rolling 12-week volume. Ship over 19,001 units in that window and you get the full 15% + $1. Drop below 1,200 units and you lose both benefits entirely. This recalculates weekly, so your tier can move up or down depending on recent activity.
Both programs cap credits at $50K or 100,000 units shipped, whichever comes first.
Now here's where the math diverges from what sellers expect.
If you ship 50,000 MCF units at the top tier, you hit the $50K credit cap. Your marginal benefit per unit drops to just the 15% discount after that point.
Compare that to a seller shipping 10,000 units. They get the full $1 credit per unit AND the 15% discount on every single shipment. Their effective savings rate is higher per unit than yours.
The credit is frontloaded. The discount is not. Amazon structured this to reward adoption, not scale.
So what can you do with this?
If you're shipping around 4,200 MCF units per month, model your savings in two phases.
Phase one: discount + credit until you hit $50K.
Phase two: discount only.
Your true cost per unit changes halfway through the year. Build that into your P&L now or you'll overshoot your margin assumptions in Q3.
The sellers who benefit most are those using MCF to test new channels without committing to a separate 3PL. You get subsidized fulfillment while you validate demand. Once the credit runs out, you're still getting 15% off, which makes the unit economics competitive if your AOV supports it.
