Bulk-Buy Break-Even: Is the Warehouse Club Worth It?

The annual fee feels worth it because everything's cheaper inside, but is it? Give it the membership cost, your household size and what you buy in bulk, and this works out the minimum saving you need to break even, then estimates whether your real shopping clears that bar. Numbers, not vibes.

I am deciding whether to buy a {MEMBERSHIP_COST} annual warehouse club membership (e.g. Costco or Sam's Club). My household size is {HOUSEHOLD_SIZE} people. Here are the items I regularly buy that are available in bulk: {ITEM_LIST} with current retail prices and typical bulk prices where I know them. Please calculate the minimum annual saving I need to break even on the membership fee, then estimate whether my buying patterns would realistically achieve that threshold. Factor in storage constraints I have described here: {STORAGE_NOTES}. Conclude with a clear yes or no recommendation and the estimated net annual saving or loss.
