Operating a routing node on the Bitcoin Lightning Network allows participants to route microtransactions and earn forwarding fees. Profitability relies heavily on total channel capacity, routing fee rates configured in Parts-Per-Million (PPM), and monthly volume turnover.
This **Bitcoin Lightning Network Routing Node Calculator** lets operators model capacity, customize monthly turnover rates, account for hosting or rebalancing costs, and calculate net profitability dynamically inside your browser.
Governing Mathematical Formulas
This calculator computes routing yields and net earnings using transparent mathematical formulas:
- Total Node Capacity (Sats):
Total Capacity = Active Channels × Avg Channel Capacity - Monthly Volume Forwarded (Sats):
Volume = Total Capacity × (Monthly Turnover % / 100) - Gross Fee Earnings (Sats):
Earnings = Volume Forwarded × (Routing Fee PPM / 1,000,000) - Gross USD Earnings ($):
Gross USD = (Earnings Sats / 100,000,000) × BTC Spot Price - Net Profit / Loss ($):
Net USD = Gross USD - Monthly Costs ($)
Worked Calculation Examples
Consider the corrected default parameters loaded into this simulator:
- Active Channels: 15 channels at 2,000,000 sats each = **30,000,000 sats** (0.30 BTC)
- Monthly Turnover: 15% turnover = **4,500,000 sats** forwarded volume
- Routing Fee: 250 PPM ($4,500,000 \times 250 / 1,000,000$) = **1,125 sats** gross earnings
- Fiat Value & Net Profit: At $68,000 BTC price, 1,125 sats equals **$0.77**. Subtracting $3.50 estimated monthly electricity and hosting costs leaves a net loss of **-$2.73**, illustrating realistic small node economics.
Frequently Asked Questions
1. What is Parts-Per-Million (PPM) in Lightning routing fees?
PPM stands for parts-per-million. A fee of 250 PPM means the routing node charges 0.025% of the total amount routed through its channels (e.g., 250 sats for every 1,000,000 sats forwarded).
2. Why is monthly turnover percentage customizable?
Different node topologies and peer connections experience varying routing demands. Smaller nodes may see lower turnover rates, while well-connected routing hubs experience much higher monthly volume.
3. Are small Lightning nodes generally profitable?
As demonstrated in our worked example, small routing nodes with limited capital often generate modest fee revenues that do not cover basic electricity and hosting overhead, making routing more of a hobby or network support mechanism than a profit generator.
4. How can I support this tool's upkeep?

5. Are my node calculations processed privately?
Yes. All computations execute 100% locally in your browser via client-side JavaScript. No channel data or inputs are sent to remote servers.
