# Cost Breakdown

See where your cloud budget is going with detailed breakdowns by service, account, or tag. Noros analyzes your cost and usage data and presents clear, actionable insights — just ask a question in plain language.

### What You Can Explore

#### Spending by Service

Understand which cloud services are driving your costs:

* "What are my top 5 most expensive AWS services?"
* "How much are we spending on RDS?"
* "Show me a cost breakdown by service for last month"

#### Spending by Account

See how costs are distributed across your linked accounts or projects:

* "Break down costs by linked account"
* "Which account is spending the most?"
* "Show me the production account's cost breakdown"

#### Spending by Tag

If you use resource tags, Noros can break down costs by any tag dimension:

* "Break down spending by team tag for Q1"
* "What are we spending on resources tagged environment=production?"
* "Show costs grouped by cost center tag"

#### Spending by Region

Identify geographic cost distribution:

* "How much are we spending in eu-west-1?"
* "Break down costs by region"
* "Which region is our most expensive?"

#### Spending by Usage Type

Get granular on specific usage categories:

* "What's our data transfer spend?"
* "Break down EC2 costs by usage type"
* "How much are we spending on storage vs. compute?"

### Granularity

Noros supports multiple levels of time granularity so you can zoom in on exactly the timeframe that matters:

* **Monthly** — High-level overviews and quarter-over-quarter trends
* **Daily** — Day-by-day visibility for identifying specific cost events
* **Hourly** — Fine-grained analysis for investigating spikes and intra-day patterns

### Combining Filters

You can combine multiple dimensions in a single question:

* "Show me EC2 costs in us-east-1 grouped by instance type for the last 3 months"
* "What's our S3 spend by linked account, excluding the dev account?"
* "Break down Lambda costs by region for Q1"

### Automated Insights

When analyzing your costs, Noros automatically highlights key takeaways:

* **Largest spend areas** — Where the bulk of your budget is going
* **Highest growth** — Services or resources with the largest percentage increase
* **Cost drivers** — The underlying factors behind spending changes

### Example Conversations

**Understanding a cost increase:**

> "Why is my bill so high this month?"
>
> Noros breaks down your spending by service, identifies the primary drivers, and shows specific dollar amounts and percentage changes.

**Departmental reporting:**

> "What did the data team spend on analytics services in March?"
>
> Noros filters your cost data by the relevant tags, services, and time period to deliver a precise answer.
