Where the Cost Dashboard gives you a monthly health summary, the Cost Explorer lets you slice costs by date range, sort and filter by any metric, and inspect growth rates and confidence scores for every service — all in one place. The page is account-scoped. Select an account from the top navigation before loading data. *** ## Date Range Use the date picker to select any historical range. Partial months are detected automatically: a warning banner appears showing each month's coverage (e.g. "Oct: 15/31 days — Partial") so you can tell at a glance whether figures represent full months or partial periods. *** ## Service Table The main table lists every service that recorded spend in the selected range. Each row shows: | Column | Description | | ---------------- | -------------------------------------------------------------------------------- | | **Service** | Service name as reported by the provider | | **Total Cost** | Total spend for this service across the full date range | | **Avg Monthly** | Total cost divided by the number of months with data | | **Peak Month** | The highest single-month cost | | **Trend** | Direction of cost change: Increasing, Stable, or Decreasing | | **CAGR** | Compound Annual Growth Rate — the annualised growth rate of this service's costs | | **Total Change** | Percentage change from first to last month in the range | | **Confidence** | Reliability of the trend and CAGR calculation based on data completeness | | **MoM** | Month-over-month change: current month vs last month | | **Anomaly** | Flag indicating whether an anomaly was detected for this service | All columns are sortable. Click a column header to sort; click again to reverse direction. ### Provider Filter Use the provider filter dropdown to show only services from a specific cloud provider. The filter uses heuristic matching on the service name — useful when you have multiple providers connected and want to isolate one. ### Partial Month Warning When your date range includes partial months, a dismissible banner explains which months are incomplete and by what percentage. Partial months affect averages and growth rate calculations — the warning helps you interpret figures correctly. *** ## Growth Metrics Growth metrics are calculated from the monthly cost time series for each service. They require at least two months of data to be meaningful. ### CAGR (Compound Annual Growth Rate) CAGR measures the average annual growth rate of a service's costs over the selected period, ignoring month-to-month volatility. A service growing steadily from $100/month to $200/month over 12 months has a CAGR of approximately 100%. * **Positive CAGR** — service costs are growing year-over-year * **Negative CAGR** — service costs are declining * **Near-zero CAGR** — service is stable ### Total Change The percentage change from the first month in the range to the last. Unlike CAGR, this is a simple point-to-point comparison and does not account for the path taken. ### Confidence | Level | Meaning | | -------------- | ------------------------------------------------- | | 🟢 High | 6+ months of data; trend is reliable | | 🔵 Medium | 3–5 months of data; trend is directionally useful | | 🟡 Low | 1–2 months of data; CAGR may be misleading | | ⚪ Insufficient | Not enough data to calculate | Low-confidence figures should be treated as directional indicators only, not precise projections. *** ## Portfolio Analytics When portfolio analytics are available for the selected account and range, a collapsible panel on the right sidebar shows portfolio-level risk metrics derived from the full service set: | Metric | Description | | ---------------------------- | ----------------------------------------------------------------------------------------- | | **Portfolio CAGR** | Overall growth rate across all services combined | | **Diversification Score** | 0–100 score measuring how spread spending is across services. Higher = better diversified | | **Concentration Index** | Mathematical measure of spend concentration across services. Lower = more diversified | | **Top 3 Concentration** | Percentage of total spend held by the three largest services | | **Risk Level** | Low / Medium / High / Critical — overall portfolio risk assessment | | **Resilience Score** | How well the portfolio would absorb a spike in any one service | | **New vs Existing Services** | Split between services that appeared in the period vs services that already existed | ### Adaptive Risk Status The adaptive risk model recalibrates periodically based on recent spending patterns. When the model detects a significant trend change or flags that recalibration is needed, an indicator appears in the analytics status panel. ### Cost Concentration Panel The concentration panel ranks the top services by their share of total portfolio spend, with a visual bar for each. Services representing more than 30% of total spend are flagged as potential single points of failure. *** ## Analytics Table View Switch to the **Analytics** tab to see a filterable, sortable table combining growth metrics with risk indicators for every service. This view adds: * **Risk Level** filter — show only Critical, High, Medium, or Low risk services * **Anomaly** filter — show only services with detected anomalies * **Confidence** filter — filter by data reliability * **Trend** filter — Increasing, Stable, or Decreasing * **Health Status** filter — from the service health categorisation The analytics table also supports CSV export for the current filtered view. *** ## Monthly Breakdown View Switch to the **Monthly** tab to see a month-by-month cost matrix: services as rows, months as columns, with each cell showing that service's spend in that month. Use this view to spot which specific months drove cost changes for any service. *** ## Exporting Use the **Export** button to download the current filtered and sorted view as a CSV file. For large datasets, an advanced export modal offers additional options including export type (summary, detailed, analytics) and metadata inclusion. *** ## Rate Limit Handling If the daily API call limit for your plan is reached, a rate limit banner replaces the error state and explains when the limit resets. Partial data collected before the limit was hit is still shown rather than discarded. *** ## Related Features Monthly executive summary with service health and burn rate.
