Summary: Understanding mining pool payout methods is crucial for maximizing Bitcoin mining profitability in 2026. This comprehensive guide breaks down PPS, PPS+, FPPS, and PPLNS reward structures, explaining how fees, variance, and transaction fee distribution impact your actual earnings. Whether you’re running Antminer S21 XP+ rigs or smaller operations, choosing the right payout model can significantly affect your bottom line.
Understanding Mining Pool Payout Fundamentals
Mining pool payout methodologies determine how rewards are distributed among miners contributing hashrate to a pool. Unlike solo mining, where variance can leave miners waiting months for a block, pools aggregate computing power to find blocks more consistently and distribute rewards based on contributed work.
The fundamental difference between payout models lies in reward predictability, fee structure, and transaction fee distribution. Each model represents a different risk-reward balance between miners and pool operators, affecting everything from daily cash flow to long-term profitability—especially critical as Bitcoin trades around $87,000-$90,000 in January 2026.
The Role of Hashrate and Accepted Shares
Your payout begins with accepted shares—valid proof-of-work submissions that meet the pool’s difficulty target. Pools adjust worker difficulty dynamically to ensure miners submit shares at optimal rates, typically every few seconds. These shares don’t directly find blocks but prove continuous contribution to the pool’s collective effort.
Block Rewards vs Transaction Fees
Bitcoin miners receive two revenue streams: the block subsidy (currently 3.125 BTC after the 2024 halving) and transaction fees from included transactions. As block subsidies decrease every four years, transaction fees become increasingly important—ranging from 0.1 to 2+ BTC per block depending on network congestion. How your pool handles transaction fee distribution dramatically impacts earnings.
Pay-Per-Share (PPS): Guaranteed Income at Premium Cost
PPS pools pay miners a fixed amount for each accepted share, regardless of whether the pool finds a block. This model transfers all variance risk from miners to the pool operator, providing maximum predictability at the cost of higher fees.
How PPS Calculates Your Earnings
The PPS rate is calculated as: (Block Subsidy / Network Difficulty) × Your Accepted Shares. If network difficulty is 146 trillion and block subsidy is 3.125 BTC, each share at difficulty 1 theoretically earns 0.0000000000214 BTC. Pools adjust this by worker difficulty—if your miner submits difficulty 10,000 shares, each counts as 10,000 difficulty-1 shares.
The PPS Trade-off: Stability vs Fees
Traditional PPS pools typically charge 4-5% fees because operators absorb variance risk. During unlucky periods, pools pay miners more than earned from blocks. However, miners receive guaranteed daily income perfect for operations with tight cash flow requirements or debt servicing. PPS also excludes transaction fees entirely—a significant drawback as fees constitute 5-15% of total block rewards in 2026.
Pay-Per-Share-Plus (PPS+): Adding Transaction Fee Bonuses
PPS+ evolved as pools recognized miners wanted stable base payments plus participation in lucrative transaction fees. This hybrid model pays standard PPS for block subsidies while distributing a calculated portion of transaction fees separately.
Transaction Fee Distribution Mechanics
PPS+ pools estimate average transaction fees based on recent block history (typically 24-48 hours). Instead of actual per-block fees (which vary wildly from 0.05 to 2+ BTC), miners receive a smoothed average. If yesterday’s average fee per block was 0.3 BTC, your PPS+ payment includes your proportional share of that 0.3 BTC based on contributed hashrate.
Fee Structures and Real Returns
PPS+ fees typically range 2-4%, lower than pure PPS since transaction fee variance remains partially with miners. Pools like ViaBTC and F2Pool pioneered this model, offering 98% predictability with modest upside during fee spikes. For miners running efficient hardware like the Antminer S21 XP+ or Antminer S23, PPS+ balances stability with transaction fee participation.
Full-Pay-Per-Share (FPPS): The Complete Reward Package (Table Section)
FPPS represents the gold standard for miners seeking both stability and full reward participation. Unlike PPS+, which uses smoothed transaction fee estimates, FPPS includes calculated transaction fees directly in the PPS rate formula.
How Foundry USA Implements FPPS
Foundry USA Pool, one of the world’s largest mining pools with approximately 290-300 EH/s, uses a sophisticated FPPS calculation trimming outliers. They sort all blocks found in a 24-hour UTC period by transaction fees, exclude the highest 3 and lowest 3, then average the middle blocks. This methodology prevents fee spikes (like during NFT ordinal frenzies) or empty blocks from skewing payouts.
FPPS Rate Calculation Example
The FPPS rate formula: FPPS Rate = (Average Transaction Fees / Average Block Subsidies) + 1.0. If average trimmed transaction fees are 0.2 BTC and block subsidy is 3.125 BTC: FPPS Rate = (0.2 / 3.125) + 1.0 = 1.064 or 106.4%. Your base PPS earnings multiply by this rate, net of pool fees.
FPPS vs PPS+ Comparison Table
| Feature | FPPS | PPS+ |
|---|---|---|
| Base Payout | Fixed per share | Fixed per share |
| Transaction Fees | Included in PPS rate (smoothed) | Separate calculation (estimated average) |
| Fee Calculation | Trimmed mean (excludes outliers) | Rolling average (24-48hr window) |
| Typical Pool Fee | 2.5-3% | 2-4% |
| Payout Variance | Minimal (1-2% daily fluctuation) | Very Low (2-5% daily fluctuation) |
| Optimal For | Large operations prioritizing consistency | Mid-size miners balancing stability & fees |
| Major Pools | Foundry USA, Antpool | ViaBTC, Binance Pool |
Pay-Per-Last-N-Shares (PPLNS): Maximum Returns with Higher Variance
PPLNS takes a fundamentally different approach, paying miners only when the pool successfully finds blocks. Rewards are distributed based on shares submitted in a recent window (“N” shares), meaning your earnings fluctuate significantly but pool fees drop dramatically.
Understanding the N-Share Window
The “N” typically represents 2-5x the network difficulty in shares. If network difficulty is 146 trillion, N might be 350 trillion shares. When the pool finds a block, it looks back at the last N shares submitted by all miners and distributes the entire block reward (subsidy + transaction fees) proportionally. If you contributed 1% of those N shares, you receive 1% of the full block reward minus fees.
Variance Reality: Feast or Famine Cycles
PPLNS variance is substantial for small pools. A pool with 1% of network hashrate (approximately 10-11 EH/s in January 2026) expects to find 1.44 blocks daily—but might find zero blocks one day and four the next. Your earnings swing accordingly. Larger PPLNS pools like Braiins Pool (30+ EH/s) reduce variance while maintaining 0-1% fees, offering 2-4% higher returns than FPPS over time if you tolerate daily fluctuations.
Who Benefits Most from PPLNS
PPLNS favors miners with patient capital who can absorb daily variance for long-term gains. It’s ideal for hobby miners, mining enthusiasts, or operations with sufficient capital reserves to weather 20-30% daily payout swings. Miners running smaller rigs or those with operational debt should avoid PPLNS due to cash flow unpredictability.
Comparing Fee Structures Across Payout Models (Table Section)
Pool fees directly impact net profitability, especially in today’s competitive landscape where margins compress between electricity costs and mining rewards. Understanding true fee structures requires looking beyond headline percentages to account for transaction fee handling.
Hidden Costs in Pool Selection
Beyond stated fees, consider: payout thresholds (some pools hold funds until reaching 0.001-0.01 BTC), payout frequency (daily vs weekly impacts cash flow), withdrawal fees (blockchain transaction costs), and stale share rates (inefficient pools waste 1-3% of hashrate on outdated work). A pool advertising 1% fees with 2% stale shares effectively charges 3%.
Payout Model Fee Comparison
| Payout Model | Typical Fee Range | Transaction Fee Treatment | Effective Fee Impact | Best For |
|---|---|---|---|---|
| PPS | 4-5% | Excluded (kept by pool) | 5-7% total loss | Absolute stability needed |
| PPS+ | 2-4% | Distributed (estimated average) | 2.5-4.5% total | Balanced risk tolerance |
| FPPS | 2.5-3% | Included (trimmed calculation) | 2.5-3% total | Optimal for most miners |
| PPLNS | 0-2% | Fully distributed (actual amounts) | 0-2% total (plus variance) | Variance-tolerant operations |
Real-World Profitability Example
Consider a miner running an Antminer S21 XP+ (270 TH/s) with $0.06/kWh electricity:
- FPPS Pool (2.5% fee): Earns ~0.00078 BTC/day ($68.60) minus $13.20 electricity = $55.40 net daily
- PPS+ Pool (3.5% fee): Earns ~0.00075 BTC/day ($66.00) minus $13.20 electricity = $52.80 net daily
- PPLNS Pool (1% fee, higher variance): Averages ~0.00082 BTC/day ($72.10) over 30 days, minus $13.20 electricity = $58.90 net daily average (but ranges $35-$85)
Over one year, PPLNS yields $1,200-$1,800 more than FPPS, but requires tolerating significant monthly variance.
Variance Analysis: How Payout Methods Affect Cash Flow
Variance—the statistical measure of reward distribution deviation—represents the most overlooked factor in pool selection. Two miners with identical hashrate and pool fees can experience vastly different cash flow patterns based solely on payout methodology.
Quantifying Variance Across Models
- PPS/FPPS: 0-2% daily variance—earnings fluctuate only due to network difficulty adjustments every 2016 blocks (~2 weeks) and minor fee variations
- PPS+: 2-5% daily variance—transaction fee estimates create minor fluctuations during network congestion spikes
- PPLNS (Large Pool 100+ EH/s): 10-20% daily variance—block finding follows statistical distribution with manageable swings
- PPLNS (Small Pool <20 EH/s): 30-50%+ daily variance—some days yield zero income, others 2-3x average
Variance Impact on Operations
For miners with monthly operational expenses, high variance creates planning challenges. A PPLNS miner expecting $1,700 monthly revenue might receive $650 one month and $2,900 the next—identical average, wildly different cash flow. This impacts everything from loan payments to payroll for larger facilities. Conversely, miners holding mined Bitcoin long-term can absorb variance easily since they’re not converting to fiat regularly.
Pool Size and Variance Relationship
Foundry USA (290+ EH/s, ~28% network share) finds blocks every 20-30 minutes on average. Even in pure PPLNS mode, variance would be minimal—but Foundry uses FPPS precisely because institutional miners demand predictability. Mid-size pools like Braiins (30 EH/s, ~3% network share) find blocks every 7-10 hours, creating acceptable PPLNS variance. Smaller pools below 10 EH/s struggle with variance so severe that PPLNS becomes impractical for professional operations.
Choosing the Right Payout Method for Your Mining Operation
Selecting a payout model requires honest assessment of your operation’s financial situation, risk tolerance, and strategic goals. No single method suits all miners—the optimal choice depends on your specific circumstances.
Financial Situation Assessment
High Operating Leverage (debt payments, tight margins, payroll obligations): Choose FPPS or PPS+ for predictable cash flow. Variance creates risk when fixed costs must be met monthly regardless of mining luck.
Low Operating Leverage (owned equipment, paid-off facilities, holding strategy): Consider PPLNS to maximize long-term returns. Extra 2-4% annual yield compounds significantly over multi-year mining operations.
Operation Size Considerations
Small Miners (<100 TH/s): FPPS or PPS+ pools provide stability while you scale. Small hashrate means your variance contribution is negligible anyway—focus on reliability and customer service.
Mid-Size Operations (100-1000 TH/s): Explore both FPPS and PPLNS. With sufficient monthly revenue ($4,500-$45,000 at current prices), you can absorb PPLNS variance while capturing higher returns. Consider splitting hashrate 70/30 between FPPS and PPLNS for balanced exposure.
Large Facilities (>1 PH/s): Often negotiate custom arrangements with pools, including hybrid models or direct access to block templates via tools like Stratum V2. At this scale, even 1% fee differences impact annual profits by $40,000+.
Strategic Mining Approaches
HODLing Strategy: If you’re accumulating Bitcoin long-term, PPLNS delivers maximum BTC accumulation. Daily fiat value matters less than total coins mined.
Regular Selling Strategy: If you sell mined Bitcoin monthly to cover expenses, FPPS/PPS+ predictability helps with financial planning and reduces risk of forced selling during low-payout periods.
Speculative Strategy: Some miners switch pools based on market conditions—PPLNS during high-fee periods (NFT ordinal crazes, DeFi booms) to capture full fee distribution, FPPS during quiet periods for stability.
Pool Hopping Prevention and Reward Systems
Mining pools implement anti-hopping measures because opportunistic miners historically exploited pool-hopping strategies, joining proportional pools early in rounds and leaving before difficulty increased, effectively stealing from honest miners.
How Pool Hopping Worked
Early proportional pools (obsolete by 2026) distributed rewards equally among all shares submitted in a round. Savvy miners noticed rounds had variable length—joining fresh rounds provided better expected value than continuing old ones. By constantly switching pools chasing “fresh” rounds, hoppers earned 20-30% more than honest miners, destabilizing pools.
Modern Anti-Hopping Mechanisms
FPPS/PPS Immunity: Share-based models pay per share regardless of round status, eliminating hopping incentive entirely.
PPLNS Design: The sliding N-share window means miners must contribute consistently to receive rewards. Hopping in at round end means your shares aren’t in the lookback window when blocks are found.
Score-Based Systems: Some pools weight recent shares higher than older shares (exponential decay), rewarding loyal miners while penalizing hoppers who disappear mid-round.
Why This Matters in 2026
Modern pools universally implement hopping-resistant methods. However, understanding these mechanics helps you recognize that consistent mining on a single pool (or 2-3 for redundancy) yields better results than constantly chasing “hot” pools. Transaction costs for moving hashrate, connection setup time, and pool performance variations typically negate any perceived hopping advantage.
Real-World Pool Recommendations by Use Case
Based on current market conditions in January 2026, here are specific pool recommendations for different miner profiles, incorporating lessons from the payout methods discussed:
For New Miners Getting Started
Braiins Pool offers both FPPS and PPLNS with transparent fee structures, excellent documentation, and beginner-friendly interfaces. Start with FPPS to understand baseline earnings, then experiment with PPLNS once comfortable. Their firmware optimization tools can boost efficiency 3-5% for compatible hardware.
For Institutional Operations
Foundry USA Pool dominates institutional mining with 2.5% FPPS fees, daily payouts, and deep liquidity for large withdrawals. Their trimmed transaction fee calculation provides optimal risk-adjusted returns for operations requiring quarterly performance reporting and stable cash flows.
For Efficiency-Focused Miners
ViaBTC combines competitive 2% PPS+ fees with merged mining opportunities (mining Bitcoin while simultaneously mining Namecoin/Elastos for bonus revenue). For miners running cutting-edge hardware like the Antminer S23 series, this maximizes per-TH earnings.
For Variance-Tolerant Enthusiasts
Ocean Pool offers unique 0% fee PPLNS with full transaction filtering control, letting miners choose which transactions to include based on personal preferences. Ideal for Bitcoin purists willing to accept higher variance for principle-based mining and maximum revenue retention.
Frequently Asked Questions
Q: Which payout method is most profitable in 2026?
A: PPLNS typically yields 2-4% higher long-term returns due to lower fees and full transaction fee distribution, but only if you can tolerate 20-30% daily earnings variance. For operations requiring stable cash flow, FPPS provides the best balance of predictability and competitive fees (2.5-3%).
Q: How do transaction fees affect different payout models?
A: PPS excludes transaction fees entirely (pool keeps them), PPS+ distributes averaged fees separately, FPPS incorporates smoothed fees into the PPS rate, and PPLNS distributes actual per-block fees. With fees averaging 0.2-0.4 BTC per block in 2026, this difference represents 6-12% of total mining revenue—making PPS significantly less profitable than FPPS or PPLNS.
Q: Can I switch payout methods without moving pools?
A: Some pools like ViaBTC and Braiins offer multiple payout options within the same pool, letting you switch between FPPS and PPLNS without changing mining configurations. However, most major pools (Foundry USA, Antpool) lock to a single methodology, requiring you to change pools entirely to switch payout types.
Q: How does pool size affect my actual earnings?
A: Pool size primarily impacts variance, not expected value. A small pool (1% network share) and large pool (30% network share) offer identical long-term expected earnings in PPLNS, but the small pool creates massive daily swings. FPPS earnings are identical regardless of pool size since payments are fixed per share. Choose large pools (>50 EH/s) for variance reduction, smaller pools only if you specifically support decentralization and can tolerate volatility.
Q: What’s the minimum hashrate needed for PPLNS to make sense?
A: Personal risk tolerance matters more than absolute hashrate, but as a guideline, miners with consistent monthly expenses should have at least $2,500-4,000 in monthly mining revenue before considering PPLNS—enough buffer to absorb a bad luck week without financial stress. Hobbyists mining for accumulation can use PPLNS at any hashrate level since they’re not dependent on steady fiat cash flow.
