Formula Used
This calculator uses an estimated performance model. It separates the score into aim, speed, accuracy, and flashlight values. Star rating creates the base value. Combo ratio rewards complete plays. Miss count reduces the score. Accuracy count is calculated from 300, 100, 50, and miss values. Mods adjust difficulty and final weight. The final result blends all parts with a power mean, then applies selected multipliers.
Accuracy = ((300 × count300) + (100 × count100) + (50 × count50)) ÷ (300 × total objects)
Total PP = ((AimPP^1.1 + SpeedPP^1.1 + AccuracyPP^1.1 + FlashlightPP^1.1)^(1 ÷ 1.1)) × multiplier
How To Use This Calculator
Enter the beatmap star rating first. Add OD, AR, CS, maximum combo, and your achieved combo. Then enter hit counts for 300, 100, 50, and misses. Select any active mods. Use the custom adjustment field only when you want to tune the estimate against your own known results. Press Calculate PP to view the result above the form. Use the export buttons to save the current calculation.
osu PP Extension Guide
Why This Tool Helps
The osu PP Extension Calculator gives players a quick way to study score strength. It is built for practice review, map comparison, and replay planning. You can test different mod choices before chasing a new score. You can also compare full combo potential against real play results. This makes training more focused and easier to measure.
Inputs That Matter
Star rating has the largest starting effect. Higher stars increase aim and speed pressure. Combo is also very important. A strong combo shows stable control through the map. Misses lower the estimate because they break rhythm and reduce consistency. Accuracy changes the final value heavily, especially on maps with high overall difficulty.
Using Mods
Mods change both difficulty and reward. Hard Rock raises pressure through tighter circles and harder timing. Double Time raises speed demand. Hidden can reward reading skill. Flashlight adds a separate visibility challenge. Easy and Half Time lower difficulty. No Fail and Spun Out apply softer final values.
Reading The Result
The total estimate is split into smaller parts. Aim PP shows cursor control value. Speed PP shows tapping and stream pressure. Accuracy PP shows timing quality. Flashlight PP appears when that mod is selected. These parts help you understand why one play scores higher than another.
Practical Training Use
Use this calculator after each serious session. Save CSV reports for spreadsheets. Save PDF reports for quick sharing. Compare maps with similar stars but different hit patterns. If a play loses many points from misses, practice consistency. If accuracy is weak, train timing windows. If combo ratio is low, focus on stable sections first.
FAQs
Is this an official osu pp calculator?
No. It is an estimated calculator for planning, learning, and comparison. Official values may differ because exact game formulas change and include deeper beatmap data.
Which inputs affect the result most?
Star rating, accuracy, combo ratio, misses, and active mods usually matter most. OD and AR also affect timing and reading bonuses.
Can I use it for every osu mode?
This version is designed for standard osu style estimates. Other modes need different performance rules and should use separate formulas.
Why does accuracy change pp so much?
Accuracy reflects timing quality. High OD maps reward strong accuracy more because precise hits are harder to maintain.
Why does a single miss reduce the result?
A miss breaks combo and suggests lost consistency. The calculator applies both miss penalty and combo ratio effects.
What does custom adjustment do?
It lets you tune the estimate. Use it when your known reference scores are consistently higher or lower than the calculator output.
Can I export my calculation?
Yes. Use the CSV button for spreadsheet work. Use the PDF button for a simple shareable report.
Why are mod results different?
Mods change map difficulty, reading demand, timing pressure, or final score weight. Each selected mod adjusts part of the estimate.
