Will Monero mining be sustainable after fees outweigh emissions?

Monero mining could remain sustainable if transaction fees eventually outweigh newly created coins, but that outcome is not guaranteed. Fees would become the main source of miner income, while Monero’s permanent block reward would still provide a baseline. The key question is whether that combined income keeps enough independent miners participating—not simply whether fees become the larger share.

Fees overtaking emissions is not a scheduled event

Emission means the new XMR created to reward miners. Since around June 2022, Monero has used tail emission: a continuing reward of 0.6 XMR per block, with blocks arriving roughly every two minutes.

That works out to about 432 newly created XMR per day. Unlike a system where new-coin rewards eventually disappear, Monero keeps this baseline indefinitely.

Transaction fees are payments you attach when sending XMR. For fees to outweigh emission over a sustained period, they would need to average more than 0.6 XMR per block.

There is no fixed date when that happens. It depends on transaction demand, transaction sizes, and Monero’s fee and block-size rules. More use does not automatically mean fees will overtake emission.

A fee-heavy reward could support miners

Miners earn newly created XMR plus transaction fees. From your perspective as a miner, the total matters more than which source supplies it.

Your ability to keep mining depends on:

• The total reward available to miners.
• Your share of the network’s mining work.
• Electricity, equipment, and cooling costs.
• What the XMR you earn can buy or sell for.

If fee income grows steadily, it could support more mining even though tail emission stays fixed in XMR terms.

But higher fees do not guarantee higher earnings for you. Better rewards can attract competing miners, spreading that income across more equipment. Monero adjusts difficulty, the amount of work needed to find a block, every block to keep block times near two minutes.

Reliability matters as much as the average

A fee-heavy system would be stronger if demand were steady rather than driven by occasional bursts.

Imagine that most blocks collect modest fees, but a few collect unusually large amounts. Average income might look healthy while individual miners face unpredictable payouts. A mining pool, where miners share work and rewards, can smooth your payouts, but it cannot make network-wide fee demand reliable.

Large differences between block rewards can also create incentives to compete over a particularly valuable recent block rather than simply build on it. This is a general concern in fee-dominated mining, not proof that Monero would become unstable.

Tail emission helps by keeping a new-coin reward available even when fees fall. However, it guarantees an amount of XMR—not a fixed electricity budget or level of network security.

The bottom line

Monero would not need fees to replace a disappearing subsidy: its 0.6 XMR tail reward continues. If fees eventually become the larger income source, mining could remain sustainable, provided total rewards support sufficient, broadly distributed mining.

For you, separate network sustainability from personal profitability. A functioning network does not mean your computer—or browser miner—will earn enough to cover its costs. Check recent rewards on a live explorer and use a current mining calculator with your measured performance and electricity price. Treat promises of guaranteed post-emission profits as a warning sign: Monero has no scheduled end to emission.
