PP Calculator for Rhythm Games
An advanced tool to calculate your Performance Points (pp) and understand your skill.
PP Calculator
The difficulty rating of the beatmap, usually from 1 to 10+.
Your accuracy on the play, from 0% to 100%.
The maximum possible combo on the beatmap.
The combo you achieved in your play.
The total number of misses in your play.
Total Performance Points (PP)
Formula Explanation: Total PP is a weighted sum of Aim PP and Speed PP, adjusted for accuracy and combo. Misses heavily penalize the final score.
Aim PP: 0.00 | Speed PP: 0.00 | Accuracy Bonus: 1.00x
What is a PP Calculator?
A pp calculator is a tool used by players of rhythm games, most notably osu!, to estimate the Performance Points (pp) awarded for a specific score on a beatmap. Performance points are a metric designed to measure a player’s skill more accurately than simple ranked score. This calculator helps players understand how factors like accuracy, combo, and misses affect their pp, allowing them to strategize for rank improvement. A good pp calculator serves as an essential resource for both casual and competitive players.
The PP Formula Explained
The actual pp formula used in games like osu! is incredibly complex, involving analysis of the beatmap’s structure, object placement, and required speed. However, this calculator uses a simplified, yet effective, model to provide a close estimation. The core idea is to calculate an “aim” value and a “speed” value based on the map’s difficulty (Star Rating) and then combine them.
A simplified formula can be expressed as:
Total PP = ( (Aim_PP ^ 1.1) + (Speed_PP ^ 1.1) ) ^ (1 / 1.1) * Accuracy_Bonus * Combo_Bonus
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Star Rating | The overall difficulty of the beatmap. | Stars (★) | 1 – 10+ |
| Accuracy | The precision of your hits. | Percentage (%) | 0 – 100 |
| Combo | The longest chain of consecutive successful hits. | Count | 0 – 3000+ |
| Misses | The number of times a note was missed. | Count | 0 – 100+ |
Practical Examples
Example 1: High Accuracy Play
- Inputs: Star Rating: 6.5, Accuracy: 99.5%, Max Combo: 1500, Player Combo: 1450, Misses: 1
- Results: This type of play, with very high accuracy and only one miss near the end, would yield a very high pp value, rewarding precision and consistency.
Example 2: Lower Accuracy, Full Combo Play
- Inputs: Star Rating: 6.5, Accuracy: 95.0%, Max Combo: 1500, Player Combo: 1500, Misses: 0
- Results: Achieving a Full Combo (FC) is a significant accomplishment. However, the lower accuracy will reduce the total pp compared to the first example. This demonstrates the heavy weighting of accuracy in the pp system. For more on ranking systems, see our guide to competitive gaming.
How to Use This PP Calculator
- Enter the Beatmap’s Star Rating: This is the most crucial factor for base pp.
- Input Your Score Details: Fill in your accuracy, the combo you achieved, the map’s max combo, and your number of misses.
- Review the Results: The calculator will instantly show you the total pp and a breakdown of aim vs. speed values.
- Analyze with the Chart: The chart visualizes the contribution of aim and speed to your total score, helping you identify strengths and weaknesses. Explore our advanced analytics tools for deeper insights.
Key Factors That Affect PP
- Accuracy: Arguably the most important factor. Higher accuracy exponentially increases pp.
- Star Rating (SR): Directly scales the potential pp of a map. Higher SR maps have a much higher pp ceiling.
- Combo: Achieving a full combo (FC) provides a significant bonus. Breaking combo, especially mid-map, is very punishing.
- Misses: Each miss drastically reduces your potential pp. A play with one miss can be worth significantly less than a full combo.
- Mods: Game modifications like Hard Rock (HR), Hidden (HD), and Double Time (DT) apply multipliers to the star rating and can dramatically increase pp.
- Map Length: Longer maps with sustained difficulty are often rewarded with more pp to reflect the stamina and consistency required.
Frequently Asked Questions (FAQ)
1. Why is this pp calculator not 100% accurate?
The official pp calculation is closed-source and extremely complex. This calculator uses a well-established public model that provides a very close approximation for most scores.
2. What is the difference between Aim PP and Speed PP?
Aim PP is awarded for difficult jumps and precise cursor movement. Speed PP is awarded for handling fast streams of notes and high BPM sections. A balanced player needs both skills.
3. How much does one miss affect my pp?
A single miss can be devastating. It not only breaks your combo but also applies a direct penalty to the total pp. The impact is larger on plays that would have otherwise been a full combo.
4. Why did my pp go down after a new score?
Your total rank is based on a weighted sum of your top scores. If you set a new score that is high, but not high enough to be one of your top plays, it might not contribute much to your overall pp. For more details, see our article on score weighting.
5. Does a higher score always mean more pp?
No. Performance Points (pp) and score are separate systems. A lower score with higher accuracy can be worth much more pp than a higher score with lower accuracy.
6. What are “unitless” values in the calculator?
“pp” itself is a unitless measure of skill. Star rating is also a relative, unitless difficulty metric.
7. Can I use this for other rhythm games?
While the concept of performance points exists in many games, this calculator is tuned for osu!-style mechanics. It can give a general idea for other games, but the values won’t be exact.
