Shopify Error Code MAX_COST_EXCEEDED: How to Fix It

Q: What is the maximum GraphQL query cost allowed in Shopify?

Shopify uses a leaky bucket algorithm with a maximum cost of 1000 points that refills at a rate of 50 points per second. The exact cost depends on your query complexity and the fields requested.

Q: How do I calculate the cost of my GraphQL query?

Each field has a cost value, and nested relationships multiply the cost. You can see the actual cost in the query response under 'extensions.cost.actualQueryCost' or use Shopify's GraphQL explorer to estimate costs.

Q: Can I increase my GraphQL cost limit?

No, the cost limit is fixed by Shopify and cannot be increased. You must optimize your queries to work within the 1000-point bucket limit and 50 points per second restore rate.

Q: Why do some fields cost more than others?

Fields that require more computational resources cost more points. Calculated fields, large text fields, and relationship queries typically have higher costs than simple scalar values like IDs or basic strings.

Q: How long should I wait before retrying after MAX_COST_EXCEEDED?

Wait based on the cost bucket refill rate. Since it restores at 50 points per second, calculate how long you need based on your required cost points. Typically wait 10-20 seconds before retrying complex queries.

Abstract

The MAX_COST_EXCEEDED error occurs when your Shopify GraphQL query consumes too many computational resources, exceeding the rate limit bucket. This happens when queries are too complex or request too much data at once, triggering Shopify's cost analysis system to protect server performance.
