Cloud cost budgets for engineering teams
Use Budgets when you need clear spend guardrails that map to engineering ownership:- Replace manual spreadsheet updates with a budget table that tracks Budget, Actual, Forecast, and Delta by line
- Assign owners per budget line to improve accountability
- Trigger alerts when actual spend or end-of-month forecast crosses a threshold
- Keep multiple budget versions and compare decisions over time
Set up cloud cost budgets and budget alerts
Create a new budget and choose the scope
Open Budgets and click Create a new budget. Select the monthly range you want to manage and choose the Virtual Dimension that splits costs into budget lines, for example
team, business_unit, or environment.Choose your budget metric
Select the currency and cost metric used to evaluate budget performance. Pick the metric your stakeholders already use for monthly reviews.
Choose a fill method
Initialize the monthly budget values with one of the available strategies.
| Fill method | When to use |
|---|---|
| Manual | You already have approved values and want direct control |
| Import CSV | Finance prepared values in a spreadsheet |
| Last year + x% | You want a simple growth model on last year’s baseline |
| Last x months + y% | You want a moving baseline with growth applied |
Assign owners to budget lines
Set an owner for each line so alerts and reviews go to the right person. This keeps accountability distributed across teams instead of centralized in one role.
Configure budget alerts
Monitor specific budget lines and add threshold rules. You can alert on:
- Actual spend exceeds threshold
- Forecasted end-of-month spend exceeds threshold

Key capabilities for engineering budget workflows
Monthly budgets by business dimension
Use Virtual Dimensions to structure budgets around how your organization operates. You can budget per team, product, environment, or any business mapping already used in Costory.Forecasting with TimesFM
Costory uses TimesFM by Google to forecast end-of-month values for each budget line. This helps you escalate risk before an overrun appears in invoiced costs.Multi-version tracking
Budgets support version history, so you can:- Keep the original baseline
- Introduce a revised plan
- Compare past assumptions with current outcomes
Owner-based accountability
Each budget line can be assigned to a specific owner. This enables practical showback, because teams can see their own target, actual spend, forecast, and delta in one place.Budget alerts for faster response
Alert rules reduce manual monitoring overhead. Teams get notified when spend risk appears, then can jump to Cost Explorer to find the root cause and take action.Use cases
VP Infrastructure review with engineering leads
Track all team budgets in one table and review which lines are on track, at risk, or exceeded before month end.Team-level showback
Give each engineering manager clear visibility into their budget line and ownership of follow-up actions.Escalation when forecasted spend drifts
Trigger an alert when a forecast crosses a threshold, then investigate the driver in Cost Explorer and coordinate with the line owner.Frequently Asked Questions
Are budgets monthly or custom period?
Are budgets monthly or custom period?
Budgets are monthly.
Can each budget line have a different owner?
Can each budget line have a different owner?
Yes. Each line can have its own owner for accountability and alert routing.
How are forecasts generated?
How are forecasts generated?
Forecasts use TimesFM by Google.
Can alerts use both actual and forecast conditions?
Can alerts use both actual and forecast conditions?
Yes. You can configure rules for actual threshold breaches and forecasted end-of-month threshold breaches.
Where should I send budget alerts?
Where should I send budget alerts?
You can send alerts to Email or Slack. Include budget line owners for faster response.
