The Bitcoin Lightning Network functions as a Layer-2 scaling mechanism that facilitates instant, low-cost payments across a network of payment channels. Instead of broadcasting every micro-transaction to the mainnet blockchain, payments route hop-by-hop through interconnected nodes based on available inbound and outbound liquidity.
Node operators provide capital liquidity to facilitate these transactions, earning micro-fees on every routed payment. Routing fees consist of a static Base Fee (charged per payment regardless of size) and a proportional Fee Rate (PPM) expressed in parts-per-million. The Lightning Network Channel & Routing Fee Forecaster empowers node runners to calculate true liquidity yields and optimize fee policy configurations.
Governing Mathematical Formulas
This client-side Layer-2 economics engine computes routing revenue and yield using standard Lightning protocol formulas:
- Proportional Fee Earnings (Sats):
Proportional Sats = Routed Sats × (PPM / 1,000,000) - Base Fee Earnings (Sats): Estimated assuming an average routed payment size of 100,000 Sats (0.001 BTC):
Payments Routed = Routed Volume / 100,000 - Total Routing Revenue (Sats):
Total Sats = Proportional Sats + (Payments Routed × Base Fee) - Monthly Revenue in USD ($):
USD Revenue = (Total Sats / 100,000,000) × BTC Spot Price ($) - Annual Channel Yield (APY %):
APY % = [(Total Sats × 12) / (Channel Capacity BTC × 100,000,000)] × 100
Worked Calculation Examples
Consider the default inputs loaded into this calculator:
- Channel Capacity: 1.5 BTC committed across routing channels
- Monthly Routed Volume: 50,000,000 Satoshis (0.5 BTC)
- Fee Configuration: 1 Sat Base Fee, 250 PPM fee rate, and a $95,000 BTC spot price
Routing 50,000,000 Sats at 250 PPM yields 12,500 Sats in proportional fees. Assuming 500 individual 100k-Sat payments, adding 1 Sat base fee per payment yields an extra 500 Sats, totaling 12,600 Satoshis per month ($11.97 USD). This yields an annual capital return of 0.10% APY on committed channel liquidity.
Frequently Asked Questions
1. What is PPM in Lightning Network routing fee policy?
PPM stands for Parts Per Million. A fee rate of 250 PPM means the node operator charges 250 Satoshis for every 1,000,000 Satoshis routed through their payment channel (equivalent to a 0.025% fee).
2. How does channel rebalancing affect net routing profit?
When payments flow primarily in one direction, channel liquidity becomes depleted on one side. Operators must execute rebalancing transactions (via circular routes or submarine swaps), paying network fees that must be subtracted from routing earnings.
3. What is the difference between inbound and outbound liquidity?
Outbound liquidity represents the local Bitcoin balance you can send or route to peers, while inbound liquidity represents the remote balance held by peer channels that allows you to receive incoming routed payments.
4. Is running a Lightning node profitable?
Node profitability depends on strategic peer connectivity, channel capacity size, competitive fee setting, and minimizing rebalancing overhead. Well-connected routing nodes earn consistent yield on BTC holdings.
5. Is this Lightning Network calculator private and secure?
