What changed in February 2026
For years, the Costco Auto Program had been off-limits to Rivian buyers. Costco's program works through dealer networks — and Rivian doesn't have dealers. The result was confusion: Rivian showed up in Costco searches, but there was no actual discount available. That changed on February 2, 2026.
Rivian officially joined the Costco Auto Program, becoming one of the very few direct-to-consumer manufacturers in the program. The discount is delivered as a member-only price reduction applied to your order — not negotiated at a dealer, but locked in through Costco's pre-arranged pricing structure with Rivian directly.
The timing matters. The federal Clean Vehicle Credit expired on September 30, 2025, taking the $7,500 federal incentive (and the lease loophole) off the table for new 2026 buyers. The Costco discount partially fills that gap — not at the same scale, but enough to meaningfully reduce your total cost when combined with state-level incentives, charger rebates, and the referral code.
How much you can save by configuration
Costco's discount on Rivian scales with vehicle MSRP. Lower-priced configurations see $1,000–$2,000 in savings; higher-priced trims like the Tri-Motor and Quad-Motor Max Pack configurations have shown $3,000–$5,000 reported discounts. Executive Costco members ($130/year tier) typically receive higher discounts than standard members ($65/year).
| Configuration | Typical Standard Member Discount | Executive Member Premium |
|---|---|---|
| R1T Dual-Motor Standard | $1,000–$1,500 | +$250–$500 |
| R1T Dual-Motor Large | $1,000–$2,000 | +$500 |
| R1T Dual-Motor Max | $1,500–$3,000 | +$500–$750 |
| R1T Tri-Motor Max Pack | $3,000–$5,000 | +$750–$1,000 |
| R1T Quad-Motor Max | $3,000–$5,000 | +$750–$1,000 |
| R1S Dual-Motor Large | $1,000–$2,000 | +$500 |
| R1S Dual-Motor Max | $1,500–$3,000 | +$500–$750 |
| R1S Tri-Motor Max | $3,000–$5,000 | +$750–$1,000 |
| R1S Quad-Motor Max | $3,000–$5,000 | +$750–$1,000 |
Discount amounts confirmed via multiple owner reports as of early 2026. Actual offer varies by location, time of purchase, and active promotions. Verify on costcoauto.com with your Costco member number before configuring.
Step-by-step: how to claim your Costco Rivian discount
Step 1 — Activate or upgrade your Costco membership
You need an active Costco membership to claim the Rivian discount. Standard membership is $65/year. Executive membership is $130/year and typically yields higher Rivian discounts — often $500 or more in additional savings on a Rivian. The Executive upgrade pays for itself many times over in a single Rivian purchase, so it's worth considering even if you're not currently enrolled. Sign up or upgrade at costco.com/membership.
Step 2 — Visit costcoauto.com and search for Rivian
Log into costcoauto.com with your Costco member number. Search for Rivian in the manufacturer dropdown or browse by EV vehicles. Select either R1T or R1S depending on your target model. R2 is expected to be added to the Costco program closer to its launch.
Step 3 — Generate your member certificate
The Costco Auto Program will generate a member-specific offer or pricing certificate tied to your Costco account. This certificate contains the discount amount and your verification details. Save it — you'll need it at the order step. Some Costco-generated offers are emailed to your registered Costco email; check your inbox if it doesn't appear on screen.
Step 4 — Configure your Rivian
You have two paths here. Path A: configure your Rivian directly on rivian.com — pick trim, battery, paint, interior, wheels, options. Use referral code RICK4348389 at checkout to claim 500 Rewards points + 3 months Adventure Network charging. Path B: configure through the Costco-linked Rivian flow if available. Either way, the Costco discount and referral code can typically both be applied (more on stacking below). Most buyers configure on rivian.com first because the Rivian configuration experience is better.
Step 5 — Present your certificate at order placement
When you finalize your order with a Rivian advisor (either in-person at a Rivian Space, by phone, or through the configuration flow), present your Costco certificate or member number. The advisor will apply the discount as a line item on your order summary. Important: verify the discount appears on your order summary before signing. If anything looks off, ask the advisor to walk through it line by line.
Step 6 — Verify at delivery and confirm stacking
At delivery, your final paperwork should show: (a) the Costco discount applied to the vehicle's purchase price, and (b) your referral code rewards credited to your Rivian Rewards account within 24 hours of taking delivery. If either is missing or incorrect, contact Rivian customer support with your order number, Costco certificate details, and the referral code you used. Don't sign delivery paperwork that doesn't reflect what was promised.
How to stack the Costco discount with everything else
The Costco discount reduces your vehicle's purchase price as a line item. The other incentives that remain available in 2026 work differently — they're tax credits, utility rebates, or Rivian Rewards points. Because they operate on different mechanisms, they generally stack with the Costco discount. Here's the full picture.
| Incentive | Amount | Stacks with Costco? | How it's delivered |
|---|---|---|---|
| Costco Auto Program discount | $1,000–$5,000 | — (this is the discount) | Price reduction at order |
| Rivian Rewards Referral Code (RICK4348389) | 500 pts + 3 months charging (~$700) | Yes, in most cases | Account credits at delivery |
| Colorado state EV tax credit | $750 (2026) | Yes — separate program | State tax filing or dealer assignment |
| Federal residential charger tax credit | Up to $1,000 (30% of install, through June 30, 2026) | Yes — separate program | Federal tax filing (IRS Form 5695) |
| Xcel Energy charger rebate (CO residents) | $500–$1,300 | Yes — separate program | Utility rebate after installation |
| Federal Clean Vehicle Credit | $0 (expired Sept 30, 2025) | N/A — no longer exists | N/A |
| Manufacturer cash/promotions | Varies | Sometimes — verify at order | Direct from Rivian |
Rivian's published terms state that some offers "may not be combined with other public offers unless permitted." In practice, the Costco discount and referral code have been combinable for most buyers as of early 2026, but verify with your Rivian advisor before signing. If forced to choose, keep the Costco discount — typically the larger dollar value.

5 mistakes buyers make claiming the Costco discount
1. Not getting Executive membership before configuring
Standard membership ($65/year) qualifies, but Executive ($130/year) typically yields $500+ in additional Rivian savings. The upgrade fee is recouped in your first purchase. Upgrade before you configure, not after.
2. Configuring on rivian.com without your Costco certificate in hand
You don't have to commit to a vehicle before you visit costcoauto.com — but you do need the certificate ready when you place your order with a Rivian advisor. Generate the certificate first, then configure.
3. Assuming the Costco discount appears automatically on your Rivian order
It doesn't. You must present the Costco certificate or member number to your Rivian advisor when placing the order. If you forget to mention it, the discount won't be applied — and Rivian may not retroactively apply it after the order is signed.
4.Not stacking the referral code because you didn't know you could
The Costco discount and the Rivian Rewards referral code are separate programs. You can claim both. Use code RICK4348389 in your Rivian configuration before finalizing the order — and present your Costco certificate at order placement.
5. Trusting the first offer you see without verifying
Costco offers can vary based on location, current Rivian promotions, and timing. If you're flexible on delivery date, check costcoauto.com for Rivian offers at quarter-end (March 31, June 30, September 30, December 31) when manufacturer incentives often increase. The combination of higher Costco discount and quarter-end Rivian incentives can add $1,000–$2,000 to your savings.
