Billing
TIR Virtual Machines support two billing models: On-Demand (hourly/per-minute) and Committed. On-Demand pricing lets you pay only for active compute time. Committed billing lets you reserve a VM for a fixed period at a lower rate, with the full amount charged upfront.
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. Committed Billing
Committed billing lets you reserve a VM for a fixed duration at a lower rate compared to On-Demand pricing. The full amount is charged upfront at the time of VM creation, making it ideal for long-running, predictable workloads.
Before creating a committed VM, ensure your account has sufficient credits to cover the full committed price. The total amount is deducted immediately upon creation.
Available Commitment Periods
Available commitment periods: 1 Month, 3 Months, and 6 Months.
The longer the commitment period, the lower the effective rate compared to On-Demand billing.
How Billing Works
| Event | Billing Status |
|---|---|
| VM is created | Full committed amount deducted upfront |
| VM is running | No additional compute charges during the period |
| VM is deleted before period ends | No refund for the remaining period |
Example
If you launch a 1-month committed VM on June 5, 2026, the full amount is deducted immediately and your VM runs until July 5, 2026 with no additional compute charges.
Committed Plan : 1 Month
Start Date : June 5, 2026
End Date : July 5, 2026
Amount Deducted : ₹X,XXX (upfront, at launch)
Additional Cost : ₹0 during the 1-month period
Committed VMs cannot be stopped during the commitment period. They can only be deleted. No refunds are issued for the remaining commitment period upon deletion.
3. 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.
4. 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 |
5. 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.
