What Is PPS, FPPS, and PPLNS in Mining Pools

Every Bitcoin mining pool has to answer one question: how does it split block rewards among contributing miners? The answer drives revenue stability, fee levels, and how much variance a miner sees in their daily payouts. Three payout methods dominate the market — PPS, FPPS, and PPLNS — and a beginner choosing a pool needs to understand the difference. The PPS vs FPPS vs PPLNS comparison is not about which is “best” but about which tradeoffs match a given operator’s situation. This guide walks through each method, explains the math, and lays out when each one is the right pick.

The short answer: three different ways to allocate block rewards

PPS (Pay Per Share) pays miners a fixed amount for every valid share submitted, regardless of whether the pool actually finds a block. FPPS (Full Pay Per Share, sometimes Pay Per Share Plus) extends PPS by also paying out average transaction fees alongside the block subsidy. PPLNS (Pay Per Last N Shares) pays miners only when the pool actually finds a block, splitting the reward among whoever contributed shares in the last N submissions.

The fundamental tradeoff runs along two axes: variance and fee level. PPS and FPPS offer the lowest variance — miners get paid steadily even if the pool has a bad week of bad luck. PPLNS offers slightly higher long-run yield because miners absorb the variance instead of the pool, but a single bad week can produce noticeably lower payouts. Fees usually run higher on PPS and FPPS (the pool charges for taking on variance risk) and lower on PPLNS. The deeper context on how pools work in general sits in the explainer on what a mining pool is.

PPS in detail

Under PPS, the pool calculates an expected value per share based on current difficulty and the block subsidy. Every share submitted earns the miner that expected value, debited from the pool’s internal balance. If a miner submits 1,000 shares on a day when the pool found zero blocks, the miner still gets paid for 1,000 shares.

The pool effectively acts as an insurer. Across many days the pool’s actual block finds average out to match its hashrate, but on any given day variance can swing wildly. PPS pools maintain a reserve to cover bad-luck streaks. The fee — typically 3–4% — funds that reserve plus operating costs.

PPS is the cleanest model for a small miner who wants predictable, smooth income. Daily payouts vary only with hashrate and difficulty, not with whether the pool got lucky or unlucky on blocks. The downside is that PPS pools historically did not pay out transaction fees — only the fixed block subsidy. That mattered less when fees were small but matters a lot now that fees can be 5–15% of total block rewards.

FPPS: PPS plus transaction fees

FPPS solves the missing-fees problem in PPS. The pool calculates a network-average transaction fee per block (typically a rolling 24-hour average) and adds that to every miner’s per-share payout. Miners get the block subsidy share plus their share of average fees, all paid out on every share regardless of whether the pool found a block.

Most large pools today use FPPS or a close variant. Foundry, AntPool, F2Pool, and ViaBTC all default to FPPS for Bitcoin. The fee is typically slightly higher than plain PPS — often 4% — but the inclusion of transaction fees makes total payouts higher in fee-heavy periods like the 2024 Runes activity and the 2025 ordinals revival.

FPPS has become the de facto industry standard for Bitcoin. New miners joining a major pool will almost always end up on FPPS by default. The pool reviews of Foundry USA, AntPool, and F2Pool all confirm FPPS defaults.

PPLNS in detail

PPLNS turns the model around: miners only get paid when the pool actually finds a block. When that happens, the pool looks back at the last N shares submitted (where N is typically a multiple of the share target, often a few hours’ worth of shares) and divides the block reward among the miners who contributed those shares, weighted by share count.

The N window matters. A short window — say, the last hour of shares — means miners who contributed recently get paid, and miners who pointed away shortly before the block hit get nothing. A long window (several hours or a day) smooths this out but also means miners get paid for shares submitted long after their session ended. Most pools tune N to balance the two.

PPLNS has two attractive properties. First, it eliminates pool-hopping incentives — under PPS a miner could in principle hop between pools to chase short-term variance, while under PPLNS the only way to get paid is to stick with the pool long enough to be present when blocks land. Second, miners capture all transaction fees from blocks the pool actually finds, which can produce big upside on fee-heavy blocks (a block with 0.5 BTC in fees is shared the same way as the 3.125 BTC subsidy).

The downside is variance. A pool with bad luck — finding fewer blocks than its hashrate would suggest over a given week — pays out less. Over months that variance averages out, but in a single week a PPLNS miner might see 10–20% less revenue than an FPPS miner on the same hashrate. Braiins Pool is one of the prominent PPLNS holdouts; the review of Braiins Pool covers the math.

Hybrid models and variations

Several pools have introduced variants of these three core models. PPS+ is PPS for the block subsidy plus PPLNS for the transaction fee component. SOLO+ is PPLNS for solo miners. Some pools offer multiple payout methods on the same account, letting the miner pick. Score-based systems weight shares by recency, blending PPS and PPLNS characteristics.

The variants tend to optimize for one of three things: incentivizing loyalty (PPLNS-flavored components), capturing fee upside (FPPS or PPS+), or simplifying tax reporting (clean PPS with no variance). For a beginner, the default FPPS on any major pool is the safest pick and what most pool documentation recommends out of the box.

Fees: what to expect and what they cover

Pool fees typically run 1–4% of mined revenue, with the level driven by payout method. PPS and FPPS pools usually charge 3–4%, reflecting the variance risk they absorb on the miner’s behalf. PPLNS pools usually charge 1–2%, because they pass variance back to the miner.

Some pools advertise 0% fees as a promotional tactic. Read the fine print: a 0% headline rate sometimes means the pool keeps all transaction fees, paying only the block subsidy proportionally. That can be a worse deal than a 4% FPPS pool when fees are high. Other pools charge a flat per-payout fee in addition to the percentage; for small miners with many small payouts, that can add up.

Over a year, fee differences add up. A 1% gap between two pools is equivalent to 1% of total revenue — for an operator earning $30,000 per year per machine, that is $300. For a fleet of 100 machines, $30,000. The math justifies spending some time comparing options before committing.

Which method suits which operator

A first-time home miner with one or two machines is usually best served by FPPS on a major pool. Steady payouts make it easy to compare actual earnings to projected hashprice, and the fee load is acceptable. Foundry USA, AntPool, and F2Pool are the common picks; latency to their North American servers is generally good from most US and Canadian locations.

A commercial-scale miner with hundreds of machines and a sophisticated treasury function may prefer PPLNS for the slightly higher long-run yield. The variance is more tolerable across a large fleet, and the elimination of fee skim on transaction-heavy blocks adds up. Braiins Pool and a few smaller PPLNS-first pools are the typical destinations.

Operators mining altcoins through Goldshell, Iceriver, or Fluminer hardware face different pool landscapes. Smaller altcoin pools sometimes use scoring-based systems or proportional payouts rather than the BTC-standard methods. The pool documentation for each coin is the right starting point. Hardware sourcing for any of these algorithms is on the Coin Web Mining catalog, with cross-context in the Bitcoin mining hub.

How to switch pools or payout methods

Switching is straightforward but worth doing deliberately. Most ASIC miners support three pool configurations for failover; change the primary pool URL in the web UI, save, and reboot. The miner will reconnect to the new pool within seconds and start submitting shares. Existing balances at the old pool will pay out on schedule once the threshold is reached.

Avoid switching pools repeatedly. Every switch produces a brief spike in stale shares as the miner discards work for the old pool’s template. PPLNS pools also penalize switching — leaving before a block is found means missing the payout from shares the miner submitted. A monthly evaluation cadence is usually fast enough; weekly switching is almost always counterproductive.
