Billing & Pricing
Understand how GPU instance billing works on SynpixCloud
Overview
SynpixCloud uses a prepaid billing model. When you create a GPU instance, the full rental amount is deducted from your account balance immediately. This ensures transparent pricing with no surprise charges.
Billing Cycles
Choose the billing cycle that best fits your workload:
| Billing Cycle | Discount | Max Duration | Best For |
|---|---|---|---|
| Hourly | No discount | 720 hours | Short experiments, testing |
| Daily | 2% off | 30 days | Development, training jobs |
| Monthly | 5% off | 12 months | Production workloads |
Example Pricing
For a GPU priced at $0.50/hour:
| Duration | Hourly Rate | Daily Rate | Monthly Rate |
|---|---|---|---|
| 1 hour | $0.50 | - | - |
| 1 day (24h) | $12.00 | $11.76 (2% off) | - |
| 1 month (720h) | $360.00 | - | $342.00 (5% off) |
Billing Precision
- Minimum rental unit: 1 hour (hourly), 1 day (daily), 1 month (monthly) — rentals are prepaid per billing cycle
- Early termination: unused prepaid time is refunded to your account balance, prorated to the second at the rate you actually paid
For example, if you terminate a 1-hour rental after 10 minutes, you are charged only for the 10 minutes used and the remaining 50 minutes are credited back to your balance. Usage is not rounded up to the hour and there is no minimum 1-hour charge.
Auto-Renewal
When Auto-Renewal is enabled:
- Your instance automatically renews when the rental period ends
- The renewal amount is deducted from your account balance
- Renewal continues until your balance is insufficient
- Same billing cycle and duration applies to each renewal
Example: You rent a GPU for 1 day with auto-renewal enabled. After 24 hours, if your balance is sufficient, another day is automatically charged and your instance continues running.
Instance Termination
When you terminate an instance:
- Early Termination: unused prepaid time is refunded to your account balance, prorated to the second (at the discounted rate you actually paid)
- Never Started: if provisioning fails or the instance never runs, the full prepaid amount is refunded
- Running Instances: run until the prepaid period ends (auto-renewal extends it when enabled)
Always terminate instances when not in use to avoid unnecessary charges.
