Costco dominates at 75.2% — bulk runs average $288 per visit. Watch checkout add-ons: big carts hide $30–50 of unplanned items easily.
The problem
Assuming Costco is “cheaper” without measuring total spend
Costco wins on unit price. It loses when carts pick up non-list items and when Walmart fill-ins happen 3× weekly. Combined big-box spend tells the truth.
How Calqio helps
Measure both, decide with data
Enter monthly estimates below, then log both merchants in Calqio for 30 days. Percent split + trip frequency beats anecdotal “we never go to Walmart much.”
Real example
Example: Costco 75% of big-box — but Walmart grew 40% YoY
Static split hides trends. A household at $1,150 Costco / $380 Walmart thought Walmart was stable. Logs showed Walmart doubled after they added pickup — convenience tax, not inflation.
Common questions
- Should I include membership and pickup fees?
- Include fees in each store’s total for fair comparison, or track fees separately.
- What if we only use one store?
- Still useful — compare against your grocery budget target, not the other store.
- Canada vs US pricing?
- Analysis method is identical; amounts differ. See localized family tracker pages.
- Does Calqio auto-split Costco and Walmart?
- Yes — when you log with those merchant labels, monthly totals split automatically.
- How often should I rerun this analysis?
- Quarterly or after a life change — new kid, remote work, moved cities.
