Here’s a hypothetical Costco member, not a real account. They upgraded to Executive at their last renewal, so this membership year’s charge included the full $65 upgrade fee. Seven months in, they sign in to Costco.com, open Membership Information and see $38 of 2% Reward accrued so far. No certificate yet; that comes later, with the Renewal Statement.
They’ve decided Executive isn’t worth it and want to drop to Gold Star. Under Costco’s refund rule, that $38 doesn’t stay with them. It comes out of the refund: about $27 back on the $65 upgrade fee, and the $38 is never issued as a certificate.
The balance that tells you whether Executive paid off is the same balance that shrinks the refund.
A Costco Executive downgrade refund is the upgrade fee you paid for the current membership year, minus any 2% Reward issued or accrued, and never less than $0. It isn’t prorated month by month, and it can’t be done online. It happens at the membership counter at your warehouse or through Member Services at 1-800-774-2678.
The rule sits in Costco’s Executive 2% Reward FAQs, under a question about the Reward being less than the upgrade fee: “To receive a refund for the current Executive upgrade fee, the membership must be canceled or downgraded to a Gold Star or Business Membership. Any 2% Reward issued or accrued will be subtracted from the refund and forfeited to the extent it exceeds the amount of any refund.” If your Reward is at or above the upgrade fee, nothing comes back, and the part above the fee is forfeited too.
Two Numbers From Your Own Account Decide the Refund
No single dollar figure answers this for every member. Both inputs belong to your account, and one of them changes every time you shop.
- Your 2% Reward as it stands today. Sign in at Costco.com and open Membership Information. Costco subtracts it whether it’s still accruing or already printed as a certificate on your Renewal Statement.
- The upgrade fee charged for the membership year you’re in now. Executive costs $130.00 a year, which Costco describes as “$65 membership fee, plus $65 upgrade fee.” Gold Star and Business are $65.00. If you upgraded partway through a year, you paid less than $65, and that smaller amount is the fee in play.
Where the “it’s prorated” advice comes from
You’ll read that a downgrade refund is prorated for the months you have left. Costco does prorate, but on the way up: its Executive Rewards terms say “We will prorate the upgrade amount based on the months remaining in your current membership.” Upgrade with three months left and you pay for three months of Executive, not twelve.
The downgrade clause has no month-by-month wording at all. Your refund doesn’t shrink as the year goes on. What shrinks it is your Reward.
One stale figure to set aside: posts quoting a “$60 upgrade fee” predate Costco’s fee increase. “Effective September 1, 2024, membership fees have increased,” moving Gold Star and Business from $60 to $65 and Executive from $120 to $130. The fees here were checked October 16, 2026.
Downgrade Now, or Finish the Membership Year?
The refund is one side of the decision. The other is a single line in the Executive Rewards terms: “A member must be a current, paid Executive Member at the end of the membership year to be entitled to the Reward.”
Put that next to the refund rule and the two paths look like this.
| What happens to | Downgrade now | Stay to renewal |
|---|---|---|
| This year’s upgrade fee | Refunded minus your Reward, never below $0 | Stays paid |
| Reward built so far | Subtracted from the refund, never issued to you | Issued as a certificate in your Renewal Statement |
| The rest of the year’s shopping | Earns no Reward | Keeps earning on qualifying purchases |
For the hypothetical member at the top, downgrading today means about $27 back. Staying means the $38 already accrued, plus whatever five more months of qualifying purchases add, arriving as a certificate. Your own numbers will differ, so set them side by side: what comes back now, against your Reward so far plus what you expect to earn before renewal.
When you estimate that last part, use Costco’s terms rather than your total Costco spending. The Reward is “approximately 2% of pre-tax purchases (less refunds) of most merchandise,” counts only purchases by the Primary and active Primary Household Cardholder made after the upgrade, and is capped at $1,250 per 12-month period. Gasoline, membership fees and other categories don’t earn it, and some exclusions vary by state. The complete exclusion list is on Costco’s Executive Membership page.
If you use the $10 monthly same-day credit, count it on its own line. It applies to orders of $150 or more pre-tax through sameday.costco.com or Instacart Marketplace, and credits “will expire on the last day of each month,” with no rollover. It’s worth up to $120 a year if you place a qualifying order every month, and nothing in a month you don’t.
As for when the certificate shows up, Costco gives the lead time two ways. The Executive Rewards terms say “approximately three months prior to the member’s renewal date,” and the 2% Reward FAQs say “approximately two months prior.” Plan around a two-to-three-month window before your renewal date, and don’t count on getting it early; the FAQs say you can’t.
A reference point for next year’s renewal, not for a downgrade you’re weighing now: earning back a full $65 upgrade fee through the Reward alone takes $3,250 of qualifying purchases in a membership year ($65 ÷ 2%). That assumes the full $65 fee, every dollar qualifying, and no value from any other Executive benefit.
If Your Renewal Statement Has Already Arrived
Costco’s rule subtracts a Reward that has been “issued,” not only one still accruing, so a certificate in your hands still counts against a downgrade refund. If that certificate is at or above the upgrade fee, the refund on this year’s fee is $0, which is also the case where Executive already paid for itself.
What Costco’s published pages don’t spell out is how a certificate you’ve already spent is treated against a mid-year refund. Ask before you downgrade rather than assume either way.
To use the certificate, you need to be an active member. It’s redeemed “toward purchases of most merchandise through the front-end registers (excluding self-checkout) at Costco warehouses in the U.S.,” and it can also go toward renewing your membership. Details such as online use and what the printed date means are in the 2% Reward FAQs.
The Downgrade Happens at the Counter or on the Phone
Costco’s list of changes you can make online covers renewing, upgrading to Executive, household cardholders, contact details, auto-renewal settings and the auto-renewal payment method. Downgrading isn’t one of them. Costco sends it to the membership counter at your local warehouse or to Member Services at 1-800-774-2678.
The published pages also don’t say how or when a downgrade refund comes back to you. So before anyone enters the change, this is what I’d ask:
“Before you process the downgrade: what 2% Reward does my account show as issued or accrued right now, what refund does that leave from this year’s upgrade fee, and how and when will I receive it?”
If the figure you hear doesn’t match your own subtraction, settle that before the change goes through. The downgrade runs on Costco’s numbers, not on your estimate.
If you’ve concluded that even the base membership isn’t worth it, a downgrade is the wrong tool. Under Costco’s Risk-Free 100% Satisfaction Guarantee, “We will cancel and refund your membership fee at any time if you are dissatisfied.” That’s a refund of the membership fee, a different transaction from the upgrade-fee refund above. Spend an unused certificate first, because you have to be an active member to redeem it.
Read the Balance Before You Decide
If a credit card renewal lands in the same season, it works much like this one: the fee can come back, but closing the card can cost points the way downgrading costs the Reward. That’s covered in how long you have to cancel after a card’s annual fee posts, and which date starts the clock. For a membership where leaving costs what you forfeit rather than a fee, there’s canceling Audible with credits left, and when to pause or switch first.
The member in the example would get about $27 for leaving now and at least $38 in certificate value for staying, so for them, finishing the year is the better trade. A member with a small Reward and a long way to renewal could land on the other side. Which side you’re on is printed on your Membership Information page, so read it before you head to the membership counter.
