Cost monitoring tells you what you spent. A budget tells Radar what you meant to spend, so it can warn you while the month is still running. Budgets live under Radar → Snowflake → Budget.
Prerequisites

Set a budget

The budget table lists an Account row and one row per warehouse, each showing month-to-date spend, a usage bar, and its monthly budget.
  1. Type a monthly amount in a row’s budget field and confirm it.
  2. Clear the field to remove that budget.
A warehouse you have budgeted stays in the table even if it stops appearing in recent spend, marked as not seen recently, so a budget never disappears silently.

Distribute a total across warehouses

If you think in terms of one monthly number for the account, use Distribute budgets:
  1. Enter the monthly total.
  2. Choose how to split it: equally across warehouses, or by historical spend using the last 30 days.
  3. Adjust any of the proposed allocations inline. Radar flags an allocation that is already below that warehouse’s month-to-date spend.
  4. Apply. The allocations are saved together as one change.

Read the chart

The budget-vs-actuals chart plots cumulative spend against a pace line: the budget spread across the month day by day, reaching 100% on the last day. Spend above the pace line means you are tracking to exceed the budget, below means you are tracking under. Filter the chart to a single warehouse or to all of them, and change the window (this month, last month, 3 or 6 months, 7 or 30 days). Over multi-month windows the pace line steps at each month boundary and uses the budget that was actually in force then, so past months stay honest after you change a budget.

Budget alerts

When a budget is set, Radar watches it on the daily cost run and alerts:
  • once when spend crosses the warning threshold, 80% of the budget by default;
  • once when it crosses 100%.
Each target alerts at most once per threshold per calendar month, and crossing both thresholds between runs sends only the higher one. Editing or removing a budget re-arms its alerts for the rest of the month. Alerts are delivered to the destinations you already configured for Data Alerts.
Budgets can also be set on a usage group rather than a single warehouse, which is usually how teams and environments are budgeted.
