PFR (Preflop Raise) is a fundamental poker statistic that measures the percentage of hands in which a player raises before the flop, revealing their level of preflop aggression and helping opponents identify playing styles.
PFR tracks how often a player enters pots as the aggressor by raising or re-raising preflop, excluding calls or limps. This metric ranges from near 0% for extremely passive players to over 30% for hyper-aggressive players, with most winning players maintaining a PFR between 15-25% in full-ring games and 18-28% in 6-max games.
The statistic works in conjunction with VPIP (Voluntarily Put Money In Pot) to paint a complete picture of preflop tendencies. While VPIP shows how many hands someone plays, PFR reveals how aggressively they play them. A player with 25% VPIP and 20% PFR plays many hands aggressively, while 25% VPIP with 5% PFR indicates a passive calling station who rarely raises.
How to Calculate PFR
The formula is straightforward:
PFR = (Number of Preflop Raises ÷ Total Hands Dealt) × 100
Example 1: Basic Calculation
Over 1,000 hands, a player:
- Raises first in (RFI): 140 times
- 3-bets: 60 times
- 4-bets: 15 times
- Cold 4-bets: 5 times
- Total preflop raises: 220
PFR = (220 ÷ 1,000) × 100 = 22%
This 22% PFR indicates a moderately aggressive player who raises roughly one in five hands.
Example 2: Multi-Session Tracking
Tracking a regular opponent across three sessions:
- Session 1: 42 raises in 200 hands = 21%
- Session 2: 38 raises in 150 hands = 25.3%
- Session 3: 55 raises in 250 hands = 22%
- Combined: 135 raises in 600 hands = 22.5%
The consistent 21-25% range confirms this is their standard style, not variance.
Practical Applications
Decision Making
PFR directly impacts your counter-strategy. Against a 30% PFR player, their opening range includes hands like K8s and Q9o, so you can 3-bet lighter for value with hands like AJ or KQ. Against a 10% PFR player opening only premium hands, those same holdings become calls or folds.
EV Calculation
When facing a raise from a player with known PFR, you can estimate their range and calculate your equity more accurately. A 15% PFR player raising from UTG has roughly: AA-88, AK-AJ, KQ. Your pocket sevens have only 36% equity against this range, making a fold correct when getting 2:1 pot odds.
Common Shortcuts
The “Gap Principle” states that PFR should typically be 70-80% of VPIP for optimal aggression. A player with 24% VPIP should have roughly 17-19% PFR. Larger gaps indicate passivity; smaller gaps indicate appropriate aggression.
Interaction with Other Concepts
PFR combines with VPIP to create player profiles:
- High VPIP + High PFR = LAG (Loose-Aggressive)
- High VPIP + Low PFR = Fish (Loose-Passive)
- Low VPIP + High PFR ratio = TAG (Tight-Aggressive)
- Low VPIP + Low PFR = Nit (Tight-Passive)
Pro Tip: PFR by position tells a deeper story than overall PFR. A player with 12% UTG PFR but 35% BTN PFR understands position, exploit them by 3-betting their late position opens lighter.
When Does PFR Matter?
Sample Size Requirements: PFR becomes reliable after 100+ hands, though 500+ hands gives a clearer picture. With fewer than 50 hands, the stat can be misleading due to variance.
Multi-Table Dynamics: Online grinders playing 20+ tables often have lower PFR (15-18%) than single-table players due to tighter automatic decisions. Live players typically show higher PFR variance session-to-session.
Game Format Impact:
- Full-ring (9-max): Standard PFR 12-20%
- 6-max: Standard PFR 18-28%
- Heads-up: PFR can exceed 50%
- Tournaments: PFR increases as blinds rise and stacks shallow
Blind Level Considerations: In tournaments, PFR naturally increases as the bubble approaches and during short-stack play. A player with 15% PFR at 100bb might show 25% PFR at 20bb due to push-fold dynamics.
Common Mistakes with PFR
Ignoring position. A 20% overall PFR looks standard, but if it’s 20% from every position including UTG, that player is too loose early and too tight late. PFR should increase dramatically from early to late position.
Over-adjusting to high PFR. Seeing 35% PFR doesn’t mean their range is trash every time. They might be card-hot, short-stacked, or adjusting to a passive table. Consider context before making hero calls with marginal hands.
Using PFR without VPIP. PFR alone tells half the story. A player with 30% PFR sounds aggressive, but if their VPIP is 32%, they’re actually playing tight-aggressive, just with a wider range than typical.
Don’t Confuse With…
VPIP measures all voluntary money put in preflop (raises, calls, and limps), while PFR only counts raises. VPIP is always higher than or equal to PFR, if you see PFR > VPIP, the tracking software has an error.
3-bet percentage specifically tracks re-raises against an initial raise, while PFR includes all preflop raises: open raises, 3-bets, 4-bets, and 5-bets combined into one statistic.
Key Takeaway
PFR reveals aggression DNA, a 10% PFR player waits for premiums while a 30% PFR player attacks constantly. Combined with VPIP, it’s your roadmap to exploiting opponents: tighten up against low PFR raises, attack high PFR players with 3-bets, and adjust your calling ranges based on their likely holdings.
