Rivian + Costco Auto Program: how to save up to $5,000
Rivian officially joined the Costco Auto Program in February 2026. Costco members can save between $1,000 and $5,000 off MSRP on the R1T and R1S — and the discount stacks with a referral code, state EV credits, and current Rivian financing offers. Here's exactly how to claim it.
The referral code is a separate program from Costco. Both can be applied to the same order.
What changed in February 2026
For years, Rivian sat outside the Costco Auto Program — a source of widespread confusion for buyers. That changed in February 2026, when Rivian officially joined Costco's program. Costco members now have access to member-only pricing on the R1T and R1S, with savings reported between $1,000 and $5,000 depending on configuration and active promotions. Standard Gold Star membership qualifies — Executive membership is not required (though some buyers report higher savings on Executive plans for certain configurations).
How to claim your Rivian Costco discount
The Costco discount is not applied through Rivian's online configurator. You must go through Costco Auto Program to access it. Here's the exact sequence.
Confirm active Costco membership
Both Gold Star and Executive memberships qualify. If you don't have a membership, sign up at costco.com — the annual fee can be recouped many times over by the Rivian discount alone.
Visit costcoauto.com and search "Rivian"
Go directly to the Costco Auto Program site (not Rivian's site). Search for Rivian to see the R1T and R1S listings with member-only pricing indicators.
Submit an inquiry with your Costco member number
You'll be asked for your Costco member number to access pricing. Alternatively, call Costco Auto Program at 1-800-755-2519 and mention Rivian.
Get connected with a Rivian-approved representative
Costco will route you to a Rivian-authorized representative — typically at a Rivian Service Center or hub. Because Rivian doesn't use traditional dealers, this is your single point of contact for the order.
Configure your Rivian with the rep — and provide referral code RICK4348389
Build your R1T, R1S, or R2 with the Rivian rep. At this stage, also provide the referral code RICK4348389. The referral program is operated separately from the Costco discount, and the two stack on the same order.
Verify the Costco discount is itemized on your order summary
Before finalizing anything, confirm the Costco discount appears as a line item on your order summary. The amount should reflect the configuration-specific savings (typically $1,000–$5,000). Do not sign delivery paperwork until this is confirmed in writing.
Complete the order through the approved representative
Finalize your order through the Rivian rep, not the public configurator. The Costco discount is applied at point of sale. Your referral Rewards points and free charging activate after delivery.
How much can you actually save?
The Costco discount is one program in a stack. Here's the full 2026 savings picture for an R1T or R1S buyer who qualifies for everything.
| Savings program | Estimated value | Stacks with Costco? |
|---|---|---|
| Costco Auto Program | $1,000 – $5,000 off MSRP | — |
| Referral code (RICK4348389) | Up to 500 Rewards points (~$500 Gear credit) + 3 months free charging | |
| Colorado state EV tax credit | $750 (2026) | |
| 2026 Rivian lease cash | Up to $6,500 (Dual Performance Large/Max) | |
| 0% APR for 60 months | Interest savings over loan term | |
| Federal residential charger credit | 30% of install, up to $1,000 (through June 30, 2026) |
The federal Clean Vehicle Credit ($7,500) expired September 30, 2025 and is not part of the 2026 stack.
Important: Rivian's published Rewards Program terms state that rewards "may not be combined with other offers." In practice, the Costco discount and Rivian Rewards referral code have been confirmed stackable on the same order. Always verify the full stack with your Rivian rep in writing before signing.
What this looks like on a real order
Example — Individual results vary
2026 R1S Dual Large
For an R1S Dual Large configured around $89,500, a Costco member who qualifies for the 2026 lease cash and lives in Colorado can effectively bring the price down by roughly $10,750 plus pick up Rewards points and three months of fast charging via the referral code. Actual savings vary by configuration, eligibility for the lease cash promotion, state of residence, and the active Costco promotion at time of order. Confirm every line item with your Rivian rep before signing.

I navigated the Rivian + Costco process for my own R1S order. Most "savings guides" online are written by affiliate sites that have never bought a Rivian. This walkthrough is the process I'd send a friend.
