What is an osu! pp Calculator?
An osu! pp calculator is a tool designed to estimate the Performance Points (pp) a player would earn from a specific play in the rhythm game osu!. Performance Points are the core metric used to rank players globally, reflecting their skill across various aspects like aim, speed, accuracy, and consistency. The higher your pp, the higher your global ranking.
This calculator takes into account crucial factors such as the map’s star rating (difficulty), your achieved accuracy, the maximum combo you maintained, the total number of objects on the map, and any game modifications (mods) you applied. By inputting these details, players can get an approximation of the pp value for a potential or past play, helping them understand how different elements contribute to their overall score.
Who Should Use an osu! pp Calculator?
- Competitive Players: To strategize which maps to play for maximum pp gain and to understand the impact of improving accuracy or combo on high-star maps.
- Aspiring Players: To set realistic goals and see how much pp they could earn by achieving certain accuracy or combo targets on maps they are practicing.
- Content Creators: To predict pp gains for challenge videos or to analyze the performance of top players.
- Curious Players: Anyone interested in the mechanics behind osu!’s ranking system and how their individual performance translates into pp.
Common Misconceptions about osu! pp
- “Higher score always means higher pp”: Not necessarily. While score is related, pp heavily weights accuracy, combo, and difficulty. A lower score with higher accuracy on a harder map might yield more pp than a higher score with lower accuracy on an easier map.
- “All mods give more pp”: Mods like Easy (EZ) or Half Time (HT) actually reduce pp, as they make the map easier. Only difficulty-increasing mods (like Hard Rock, Double Time, Hidden, Flashlight) provide pp multipliers.
- “Only full combo matters”: While a full combo is ideal, a very high combo with a few misses on an extremely difficult map can still yield significant pp, especially if accuracy is maintained.
- “PP is purely about raw skill”: While skill is paramount, pp also rewards consistency and the ability to perform well under pressure (e.g., maintaining combo).
osu! pp Calculator Formula and Mathematical Explanation
The official osu! pp calculation is an incredibly complex algorithm, constantly refined by the game’s developers. It involves detailed analysis of beatmap properties (like aim strain, speed strain, rhythm, flashlight, and approach rate) and player performance metrics. Our osu! pp calculator uses a simplified, illustrative model to provide an accessible estimate, focusing on the primary factors that influence pp.
Step-by-Step Derivation (Simplified Model)
- Base PP from Star Rating: The fundamental difficulty of the map is the starting point. Higher star ratings inherently offer more potential pp.
Base PP = (Star Rating ^ 2) * 10 (This is a conceptual multiplier, actual formula is more complex).
- Accuracy Contribution: Accuracy is crucial. A higher percentage of perfect hits significantly boosts pp.
Accuracy Factor = (Accuracy / 100) ^ 2 (Exponential weighting for accuracy).
- Combo and Miss Penalty: Maintaining combo and avoiding misses are vital for maximizing pp. A break in combo or a miss reduces the overall pp.
Combo Factor = (Max Combo Achieved / Total Objects) ^ 0.7 (Rewards high combo, penalizes breaks).
Miss Penalty = 1 - (Number of Misses / Total Objects * 0.5) (A direct reduction based on misses).
Combo/Miss Contribution Factor = Combo Factor * Miss Penalty
- Mod Multiplier: Certain mods increase the difficulty and thus the potential pp.
Mod Multiplier = (Specific Mod Multiplier) (e.g., DT/NC: 1.12, HR: 1.06, HD: 1.05, FL: 1.10, EZ: 0.5, HT: 0.3).
- Total Estimated PP: All factors are multiplied together to get the final estimated pp.
Total PP = Base PP * Accuracy Factor * Combo/Miss Contribution Factor * Mod Multiplier

Practical Examples (Real-World Use Cases)
Let’s look at a couple of scenarios to illustrate how the osu! pp calculator works and how different inputs affect the outcome.
Example 1: High Accuracy, Full Combo on a Mid-Difficulty Map
- Star Rating: 5.5
- Accuracy: 99.5%
- Max Combo Achieved: 750
- Total Objects on Map: 750
- Number of Misses: 0
- Applied Mods: None
Calculation Interpretation: In this scenario, the player achieved a near-perfect play on a moderately difficult map. The high accuracy and full combo will result in a strong pp gain, as there are no penalties for misses or combo breaks. The osu! pp calculator would show a significant pp value, reflecting excellent execution for the map’s difficulty.
(Using the calculator with these values would yield approximately 150-180 pp depending on the exact internal scaling.)
Example 2: Lower Accuracy, Some Misses on a High-Difficulty Map with Mods
- Star Rating: 7.0
- Accuracy: 95.0%
- Max Combo Achieved: 800
- Total Objects on Map: 1000
- Number of Misses: 5
- Applied Mods: Double Time (DT)
Calculation Interpretation: Here, the player tackled a much harder map with the Double Time mod, which significantly increases the map’s effective difficulty and provides a pp multiplier. Despite a lower accuracy and a few misses, the high base difficulty and the DT mod’s multiplier can still result in a substantial pp gain. The misses and lower accuracy will reduce the potential pp, but the difficulty bonus from the map and mod will still make it a valuable play. This demonstrates how difficulty and mods can sometimes outweigh minor imperfections.
(Using the calculator with these values would yield approximately 250-300 pp, showcasing the power of high star ratings and mods despite imperfections.)

Key Factors That Affect osu! pp Calculator Results
The calculation of Performance Points in osu! is a multi-faceted process, influenced by several critical factors. Understanding these can help players improve their game and maximize their pp gains.
- Star Rating (Map Difficulty):
The most fundamental factor. Higher star ratings indicate more complex beatmaps with faster object speeds, denser patterns, and more demanding rhythm. Playing and performing well on higher star maps inherently yields more pp. The osu! pp calculator uses this as the base for its estimation.
- Accuracy:
Accuracy is paramount. Hitting objects precisely (300s) contributes significantly more to pp than hitting them less accurately (100s or 50s). Even a small drop in accuracy on a high-difficulty map can lead to a substantial reduction in pp. The calculator heavily weights this factor, as it reflects a player’s precision and timing.
- Max Combo Achieved:
Maintaining a high combo throughout a map is crucial. Each consecutive hit increases the combo multiplier, which in turn boosts the score and pp. Breaking combo, especially early in a map, severely penalizes pp. The osu! pp calculator considers the ratio of max combo to total objects to assess consistency.
- Number of Misses:
Misses are the most detrimental factor to pp. Each miss not only breaks combo but also incurs a direct penalty to the overall pp. Minimizing misses, even on challenging maps, is often more beneficial than achieving slightly higher accuracy with more misses. Our osu! pp calculator applies a significant penalty for each miss.
- Applied Mods:
Certain mods can drastically alter a map’s difficulty and, consequently, its pp potential. Difficulty-increasing mods like Double Time (DT), Hard Rock (HR), Hidden (HD), and Flashlight (FL) apply multipliers to pp. Conversely, difficulty-decreasing mods like Easy (EZ) and Half Time (HT) reduce pp. Strategic use of mods is key for pp farming.
- Map Length and Object Count:
Longer maps with more objects generally offer higher pp potential, assuming consistent performance. This is because there are more opportunities to build combo and demonstrate sustained skill. The total objects input in the osu! pp calculator helps contextualize combo and misses.
Frequently Asked Questions (FAQ) about osu! pp Calculator
Q: Is this osu! pp calculator 100% accurate compared to the game?
A: This calculator provides a strong estimate based on a simplified model of the official osu! pp algorithm. The actual in-game calculation is extremely complex, involving detailed beatmap analysis (aim strain, speed strain, etc.) that cannot be fully replicated without parsing beatmap files. It’s designed to give you a very good approximation and understanding of pp mechanics, not an exact match for every single play.
Q: What is “pp” in osu! anyway?
A: “PP” stands for Performance Points. It’s the primary metric used in osu! to rank players globally. PP is awarded for plays that demonstrate skill, accuracy, and consistency on beatmaps, with harder maps and better performance yielding more pp.
Q: How do mods like DT or HR affect pp?
A: Mods like Double Time (DT) and Hard Rock (HR) increase the difficulty of a map (e.g., faster approach rate, higher overall difficulty, increased circle size for HR). Because they make the map harder, they apply a multiplier to the potential pp earned from a play, significantly boosting your pp gains if you can perform well with them.
Q: Why did my pp not increase much even with a high score?
A: PP is not solely based on score. It heavily prioritizes accuracy, combo, and the map’s star rating. If your high score was on an easier map, or if it involved lower accuracy or many combo breaks, the pp gain might be minimal. Focus on improving accuracy and combo on maps within your skill range to see better pp gains.
Q: Can I use this osu! pp calculator to predict my rank?
A: While this calculator helps you understand individual play pp, predicting your exact rank is difficult. Your total pp is the sum of your best plays, with a decay factor for lower-ranked plays. To predict rank, you’d need to sum up all your top plays’ pp values, which is beyond the scope of a single-play calculator.
Q: What are typical pp values for different skill levels?
A: This varies greatly. A new player might earn 5-20 pp per play. Intermediate players might aim for 50-150 pp plays. Advanced players often achieve 200-400 pp per play, and top players can achieve 500-1000+ pp on extremely difficult maps. The osu! pp calculator helps you benchmark your own plays.
Q: What if I don’t know the “Total Objects on Map”?
A: You can often find this information on the beatmap’s page on the osu! website or by playing the map and observing the total hit objects. If you can’t find the exact number, you can estimate it based on the map’s length and density, but a precise number will yield a more accurate pp estimate from the osu! pp calculator.
Q: Does this calculator consider specific map properties like AR/OD/CS?
A: Our simplified osu! pp calculator primarily uses the aggregated “Star Rating” as the difficulty input, which implicitly accounts for AR (Approach Rate), OD (Overall Difficulty), and CS (Circle Size). The official osu! algorithm breaks these down further, but for a user-friendly estimate, Star Rating is the most accessible and comprehensive input.
