About lightning network fees

Lightning Network fees are how a Bitcoin layer-2 payment network keeps everyday transactions at sub-cent cost. The Lightning Network itself is a network of payment channels layered on top of Bitcoin. Two parties lock funds into a shared channel, then send payments back and forth off-chain. The net result settles on Bitcoin's base layer only when the channel closes. A Lightning invoice is the QR code or text string a receiver generates for one specific payment amount. A Lightning address works like an email address, letting you receive payments to one fixed name instead of generating a new invoice every time. Wallets such as Phoenix, Muun, and Cash App's built-in Lightning support handle the channel management, so most users never see a raw channel or invoice. An on-chain Bitcoin payment settles directly on the base layer and pays a miner fee every time. A Lightning payment instead routes off-chain through existing channels, and only touches the base layer when a channel opens or closes. You don't pay miners — you pay the routing nodes that forward your payment across pre-funded channels. The BOLT #7 spec defines the math: each hop charges a base fee plus a parts-per-million (ppm) cut of the amount routed, summed across the whole path. For a typical small payment in 2026, total Lightning routing fees come in well under one cent — which is the only reason tips, podcast streaming, and faucet payouts work economically on Bitcoin at all.

How it works

BOLT #7 defines the per-hop formula as fee_base_msat + (amount_msat × fee_proportional_millionths ÷ 1,000,000), where all values are millisatoshis (1 sat = 1,000 msat). Each routing node along the path applies its own base + ppm to the amount it forwards on its outgoing channel, and your wallet pays the sum. Default base fees are typically 1 sat (1,000 msat); public-channel ppm rates in 2026 sit in a wide 20–150 ppm range depending on the operator. Bitcoin miner fees are paid only when channels open or close on the base layer — never during normal routing. That on-chain cost gets amortized across every Lightning payment the channel handles before it closes.

How to pay less

1Use a well-connected wallet — fewer hops and better pathfinding means cheaper, more reliable routes.
2Keep individual payments small to mid-sized — ppm scales with amount and large payments hit more liquidity failures.
3If you receive often, arrange inbound liquidity ahead of time via an LSP (Phoenix, Voltage, Megalith) or LN+ rings to avoid emergency channel-open costs.
4Check your wallet's payment log for high-fee paths — some routes consistently overcharge and a fresh path is often cheaper.

Pros

Routing fees are routinely sub-cent regardless of fiat amount, because they're per-hop on millisatoshis, not auctioned block space.
Settlement is near-instant — HTLCs clear in seconds versus ~10-minute Bitcoin blocks.
No miner fee on the payment itself; the only on-chain cost is at channel open and close, amortized across every payment in between.

Watch out for

Opening and closing channels still pays Bitcoin on-chain fees (sat/vB), and during mempool spikes that can be significant.
Liquidity can fail mid-route on larger or off-the-beaten-path payments — wallets retry, but time-to-pay grows and very large payments may not route at all.
Receive-side liquidity isn't free: LSPs like Phoenix charge ~1% of liquidity provisioned, and custodial wallets simplify the trade-off by holding your sats.

Common questions

What is the Lightning Network?

The Lightning Network is a payment network built on top of Bitcoin that lets two parties send payments back and forth through a shared, pre-funded channel instead of settling every payment on Bitcoin's base layer. Only the channel's opening and closing transactions touch the base layer and pay a miner fee. Everything in between routes off-chain through Lightning nodes for a small routing fee, which is why Lightning payments typically cost well under one cent regardless of how many payments pass through the channel.

What's the difference between a Lightning wallet and an on-chain Bitcoin wallet?

A Lightning wallet like Phoenix, Muun, or Cash App manages payment channels for you and sends most payments off-chain, so it needs an internet connection and, for a non-custodial wallet, some inbound liquidity to receive. An on-chain Bitcoin wallet sends every payment directly on the base layer, with no channel required, but pays a miner fee on every send instead of a small routing fee. Many wallets, including Cash App, support both and let you pick per payment.

How are Lightning Network fees calculated?

Lightning Network fees are calculated per hop using the BOLT #7 formula: fee_base_msat + (amount_msat × fee_proportional_millionths ÷ 1,000,000), with all values in millisatoshis. Each routing node along the path adds its own base fee plus a ppm cut of the routed amount, and your wallet pays the sum. A typical small payment across 2–4 hops costs only a few sats total.

What is ppm in Lightning fees?

Ppm stands for parts per million and is the proportional fee rate a routing node charges on the amount it forwards. A 100-ppm node takes 0.01% of the routed amount — 100 sats on a 1,000,000-sat payment. Median public-channel rates in 2026 sit roughly in the 20–150 ppm range depending on the operator's strategy.

Why are Lightning fees so much cheaper than on-chain Bitcoin?

Lightning fees are cheaper because payments never touch the Bitcoin base layer during normal routing — they're off-chain HTLCs between nodes that already share funded channels. You only pay the routing nodes' small base + ppm fees, not the per-block sat/vB miner auction. Bitcoin miner fees apply only when channels are opened or closed.

Do I pay a fee to receive on Lightning?

You don't pay a routing fee to receive a Lightning payment — the sender's wallet pays it. But to receive at all you need inbound channel capacity, which usually means either opening a channel yourself (pays an on-chain miner fee) or using a Lightning Service Provider like Phoenix or Voltage, which typically charges around 1% of the liquidity it provisions.

When should I use Lightning instead of on-chain Bitcoin?

Use Lightning for everyday payments — tips, small purchases, podcast streaming, micropayments, and most sub-$100 transfers — where sub-cent fees and instant settlement matter. Use on-chain Bitcoin for large final settlements, payments to recipients who don't run Lightning, or amounts that exceed available routing liquidity on the network.
