Which GCP SKUs am I spending the most on?

SELECT
  service.description                                        AS service,
  sku.description                                            AS sku,
  sku.id                                                     AS sku_id,
  ROUND(SUM(cost), 2)                                        AS cost,
  SUM(usage.amount_in_pricing_units)                         AS usage_amount,
  ANY_VALUE(usage.pricing_unit)                              AS pricing_unit,
  ROUND(SAFE_DIVIDE(SUM(cost), SUM(usage.amount_in_pricing_units)), 6) AS effective_unit_rate
FROM `PROJECT.DATASET.gcp_billing_export_v1_XXXXXX_XXXXXX_XXXXXX`
WHERE _PARTITIONTIME >= TIMESTAMP_SUB(CURRENT_TIMESTAMP(), INTERVAL 35 DAY)
  AND cost > 0
GROUP BY service, sku, sku_id
ORDER BY cost DESC
LIMIT 100;
