+# Cost Calculation Improvements
+
+## Overview
+
+This enhancement extends the existing cost calculation system to support additional Azure resource types beyond AKS clusters and VM Scale Sets. The system now supports:
+
+- **Virtual Machines** - Individual VMs with accurate SKU detection
+- **Application Gateways** - With tier and capacity-based pricing
+- **PostgreSQL Flexible Servers** - With compute tier-based pricing  
+- **SQL Managed Instances** - With vCore-based pricing
+
+## Key Features
+
+### 1. Scalable Resource Type Support
+
+The system uses a new data format that includes resource type information:
+```
+ResourceType,SKU,OS/Tier,Count
+```
+
+Examples:
+```
+VM,Standard_D2s_v3,Linux,2
+ApplicationGateway,Standard_v2,Standard_v2,1
+FlexibleServer,GP_Standard_D2ds_v4,PostgreSQL,1
+SqlManagedInstance,GP_Gen5_4,GeneralPurpose,1
+```
+
+### 2. Backward Compatibility
+
+The system maintains full backward compatibility with the existing format:
+```
+SKU,OS,Count
+```
+
+Legacy entries are automatically treated as VM resources.
+
+### 3. Enhanced SKU Detection
+
+- **Virtual Machines**: Extracts actual VM size and OS type from Azure properties
+- **Application Gateways**: Detects tier, name, and capacity from Azure SKU properties
+- **Flexible Servers**: Extracts compute tier and VM size from Azure SKU properties
+- **SQL Managed Instances**: Detects service tier, generation, and vCore count
+
+### 4. Robust Pricing API Integration
+
+- Supports different Azure Pricing API product names for each resource type
+- Includes fallback pricing when API is unavailable
+- Maintains existing retry logic and error handling
+
+### 5. Resource-Specific Cost Calculations
+
+While most resources use the standard shutdown schedule calculation, the system is designed to support resource-specific cost models if needed in the future.
+
+## Implementation Details
+
+### New Functions in `resource-details.sh`
+
+1. **`countResource()`** - Enhanced resource counting with type support
+2. **`get_vm_costs()`** - Collects Virtual Machine cost information
+3. **`get_appgateway_costs()`** - Collects Application Gateway cost information
+4. **`get_flexible_server_costs()`** - Collects Flexible Server cost information
+5. **`get_sqlmi_costs()`** - Collects SQL Managed Instance cost information
+
+### Enhanced `cost-calculator.py`
+
+1. **`get_fallback_pricing()`** - Provides fallback pricing when API is unavailable
+2. **`azPriceAPI()`** - Enhanced to handle different resource types and product names
+3. **Main processing loop** - Supports both new and legacy data formats
+
+## Azure Graph Queries
+
+The system uses enhanced Azure Resource Graph queries to extract pricing-relevant information:
+
+### Virtual Machines
+```kql
+resources
+| where type =~ 'Microsoft.Compute/virtualMachines'
+| where tags.autoShutdown == 'true'
+| project name, resourceGroup, subscriptionId, ['tags'], 
+  properties.hardwareProfile.vmSize, properties.storageProfile.osDisk.osType
+```
+
+### Application Gateways
+```kql
+resources
+| where type =~ 'microsoft.network/applicationgateways'
+| where tags.autoShutdown == 'true'  
+| project name, resourceGroup, subscriptionId, ['tags'],
+  properties.sku.tier, properties.sku.name, properties.sku.capacity
+```
+
+### PostgreSQL Flexible Servers
+```kql
+resources
+| where type =~ 'microsoft.dbforpostgresql/flexibleservers'
+| where tags.autoShutdown == 'true'
+| project name, resourceGroup, subscriptionId, ['tags'],
+  properties.sku.tier, properties.sku.name
+```
+
+### SQL Managed Instances
+```kql
+resources
+| where type =~ 'microsoft.sql/managedinstances'
+| where tags.autoShutdown == 'true'
+| project name, resourceGroup, subscriptionId, ['tags'],
+  properties.sku.tier, properties.sku.family, properties.vCores
+```
+
+## Adding New Resource Types
+
+To add support for additional resource types in the future:
+
+1. **Create collection function** in `resource-details.sh`:
+   ```bash
+   function get_newresource_costs() {
+       # Azure graph query to get resources with SKU info
+       # Process each resource and call countResource
+   }
+   ```
+
+2. **Add to main collection** in `resource-details.sh`:
+   ```bash
+   get_newresource_costs
+   ```
+
+3. **Add pricing logic** in `cost-calculator.py`:
+   ```python
+   elif resource_type == "NewResourceType":
+       productName = "'New Resource Product Name'"
+   ```
+
+4. **Add fallback pricing** in `cost-calculator.py`:
+   ```python
+   "NewResourceType": {
+       "SKU_Name": hourly_rate
+   }
+   ```
+
+## Testing
+
+The implementation includes comprehensive tests covering:
+
+- Legacy format compatibility
+- New format support  
+- Mixed format handling
+- All resource types
+- Stay-on-late functionality
+- Error handling and fallback pricing
+
+Run tests with:
+```bash
+# Basic functionality test
+./test_cost_calculation.sh
+
+# Comprehensive test suite  
+./final_test_suite.sh
+```
+
+## Cost Estimation Accuracy
+
+The system maintains the existing 25% buffer for unmeasurable costs and uses realistic fallback pricing when the Azure Pricing API is unavailable. This ensures cost estimates remain useful even in degraded conditions.
+
+## Future Enhancements
+
+Potential future improvements:
+- Resource-specific cost calculation models
+- Regional pricing support
+- Reserved instance pricing consideration
+- More granular Application Gateway data processing costs
+- Disk and storage cost calculations
