To calculate this accurately, you need four inputs:
- Income per license (monthly or yearly).
- License cost.
- Hardware cost (server, storage drives, networking equipment, etc.).
- Electricity and internet costs per month.
Then use these formulas:
- Total investment = License cost + Hardware cost.
- Monthly profit = Income per license − Monthly electricity − Monthly internet − Other operating costs.
- Payback period = Total investment ÷ Monthly profit.
- Licenses needed = Target monthly income ÷ Monthly profit per license.
For example, if:
- License cost = $500
- Hardware = $1,500
- Electricity = $30/month
- Income = $100/month per license
Then:
- Total investment = $2,000
- Monthly profit ≈ $70
- Payback period ≈ 29 months
- To earn $1,000/month, you would need about 15 licenses ($1,000 ÷ $70 ≈ 14.3, rounded up).
If you provide the current DeNet license price and expected income per license, I can calculate the exact payback period and the number of licenses needed for your target income.
