Should I buy hardware to earn more?
A natural question once your first device is earning: should I buy another machine specifically for this? This chapter gives you the math. The honest short answer: it depends on your local power cost, used-hardware availability, and sustained demand at your tier. Read the numbers, plug in your own values, decide.
This is not investment advice. Real returns vary widely. Don't borrow money to buy hardware.
Time: 15-30 minutes to run the math for your situation.
The ceiling
Pro/Business jobs settle at $0.08 per device-hour at the platform level. That's the ceiling on what a single device can generate while running at full eligible utilization. The device-owner share is set by the platform fee schedule. For the math below we use $0.08 as the top-line and you can apply your actual take-home percentage.
Monthly revenue ceiling per device
revenue_ceiling_usd = 0.08 × hours_per_day × days_per_month
| hours/day | days/month | gross |
|---|---|---|
| 8 | 30 | $19.20 |
| 12 | 30 | $28.80 |
| 16 | 30 | $38.40 |
| 24 | 30 | $57.60 |
Reality check: utilization is rarely 100% of available hours. A device with a 16-hour schedule actually earning jobs 60-70% of those hours nets roughly $23-27 gross in the table above. [VERIFY: realistic utilization rates — internal data shows 50-80% range depending on capability tier and time zone]
Subtract power
monthly_power_cost = kWh_per_hour × hours_per_day × days_per_month × usd_per_kWh
Typical draws under sustained load:
- Mid-range desktop CPU: 0.10-0.15 kWh/hour
- Workstation with GPU under load: 0.25-0.40 kWh/hour
- Laptop on charger: 0.05-0.08 kWh/hour
Example: GPU workstation, 16 hours/day, 30 days, $0.18/kWh: 0.30 × 16 × 30 × 0.18 = $25.92/month
In some markets (parts of EU at €0.35+/kWh, California peak rate) the power cost exceeds the gross — you're paying to compute. In others ($0.08/kWh hydro regions) the math is much friendlier.
Subtract depreciation
A $1,500 workstation amortized over 36 months adds $41.67/month of hidden cost. Used hardware shifts the math substantially.
Break-even formula
break_even = (hardware_cost / lifetime_months) + monthly_power_cost
monthly_profit = revenue × utilization - break_even
If monthly_profit is negative at realistic utilization, don't buy.
The honest answer
For most readers in most regions: buying new hardware specifically for Zyra earnings does not pay off. The cases where it does:
- You have very cheap power (industrial rate, hydro region, home solar with excess capacity).
- You're buying used hardware (eBay, refurb) at heavy discount.
- You already had a use case for the hardware (gaming, development) and Zyra is incremental.
The cases where it almost certainly does not:
- New gaming-tier GPU bought primarily for compute earnings.
- Any scenario where you're financing the purchase.
- High-electricity-cost regions running CPU-only devices.
What does pay off
- Running hardware you already own at higher utilization.
- Replacing a noisy fan or paste so an existing device doesn't thermal-throttle.
- Upgrading the internet connection if your upload is constrained (chapter 2).
Not investment advice
This page is a math worksheet, not financial guidance. Real outcomes depend on factors outside the spreadsheet: demand at your tier, agent uptime, hardware failures, tax treatment. Consult a tax professional for your local situation.
