How it works

The calculator estimates yearly savings as monthly spend times 12 times your assumed savings rate. Executive also receives the reward percentage on eligible spend. Net benefit is savings plus rewards minus the annual fee.

Break-even monthly spend is the point where estimated savings and rewards equal the membership fee. If your regular prices are not actually higher than Costco, lower the savings rate.

Frequently asked questions

How is the Costco membership break-even calculated?
The calculator divides the annual fee by your expected savings rate and eligible reward rate. With a $65 fee and 15% savings, break-even is about $36 per month.
Does Executive always beat Gold Star?
No. Executive needs enough eligible spending for the 2% reward to overcome the higher annual fee. The recommendation compares both tiers from the same monthly spend.
What savings rate should I use?
Use the discount you realistically get versus your usual stores. The default 15% is an assumption, not a promise that every item is cheaper.
Should gas, travel, and services be included?
Include categories only if they are part of your normal spending and eligible for the savings or rewards you are modeling.
Is this exact for every Costco rule?
No. It is a planning calculator. Official membership terms, eligible categories, reward exclusions, and caps should be checked before buying.
