Billing
TIR Virtual Machines are billed on an On-Demand (hourly/per-minute) basis. You pay only for the time your VM is actively running — no charges when the VM is stopped.
1. On-Demand Pricing
On-Demand pricing is calculated per minute, so you are charged only for actual compute time.
How Billing Works
| Event | Billing Status |
|---|---|
| VM enters Running state | Billing starts |
| VM enters Stopped state | Billing pauses |
| VM is restarted | Billing resumes |
| VM is deleted | Billing stops permanently |
You are not billed while the VM is in the Waiting (provisioning) state.
Example
If the hourly rate for your VM plan is ₹90/hr and you run it for 20 minutes:
Hourly Rate : ₹90/hr
Usage : 20 minutes
₹90 ÷ 60 = ₹1.50 per minute
₹1.50 × 20 = ₹30 total billed
2. Storage Billing
Your VM's workspace disk is billed independently from compute time. Storage charges continue even when the VM is stopped, and stop only when the VM (and its disk) is explicitly deleted.
| Storage Type | Billed Independently |
|---|---|
| Workspace Disk | Yes — continues while VM exists, even when stopped |
| Attached Datasets | Yes — billed under Dataset pricing, not VM pricing |
| Shared File System (SFS) | Yes — billed under SFS pricing |
To avoid unexpected storage charges, delete any storage resources you no longer need after deleting the VM.
3. What Is Not Billed
The following features are included at no additional charge:
| Feature | Details |
|---|---|
| SSH Keys | Adding, rotating, or removing SSH keys is free |
| Security Groups | Creating and attaching Security Groups is free |
| Reserved IP attachment | Attaching a Reserved IP to a VM is free; the Reserved IP itself may have a separate charge |
| Startup Scripts | Creating and running startup scripts is free |
| VM provisioning time | The Waiting state (while the VM is being provisioned and booting) is not billed |
4. Cost Estimation
Use the E2E Pricing Calculator to estimate your VM cost based on the GPU plan, vCPU/RAM configuration, storage size, and expected usage hours per month.
