Umamusume Rating Calculator
Estimate your Uma Musume evaluation score from core stats, skill points, unique skill level, and aptitude bonus before you compare race performance in Umalator.
Calculate Evaluation Score
Enter the five visible stats plus skill and bonus assumptions. The calculator returns an estimated rating, current rank, distance to the next rank, and a quick build-balance signal. It is a transparent planning model, not an official hidden formula replica.
Estimated Output
Adjust the fields to estimate rating and rank gap.
Example Rating Check
A medium-distance build with 1200 Speed, 700 Stamina, 1100 Power, 500 Guts, 900 Wisdom, solid learned skills, and a level 3 unique skill can be checked before you decide whether to chase another rank threshold or protect race performance.
- Use the next-rank gap to decide whether extra skill points are worth farming.
- Keep the balance signal in mind: a higher rating can still race poorly if Stamina or Power is too low.
- After rating planning, run the same build in Umalator to compare win rate and placement spread.
How to Use the Umamusume Rating Calculator
Use this calculator when you want a quick evaluation-score estimate before choosing between more stats, more skills, or a full race-simulation check.
1. Enter visible stats
Add Speed, Stamina, Power, Guts, and Wisdom from your current or planned trainee. Use final expected values if you are comparing future builds.
2. Add learned-skill value
Enter the rough value of learned skills. Do not count unspent skill points unless you are already sure which skills will be purchased.
3. Choose bonus assumptions
Set unique skill level and aptitude fit. These are planning bonuses, so keep them conservative when the build is not finalized.
4. Compare rank and performance
Use the rating and next-rank gap to guide training choices, then open Umalator to confirm the build still performs in races.
What the Rating Estimate Measures
The page is built for consistent comparison, not for claiming perfect hidden-formula accuracy. It weights over-cap stats, learned skills, unique skill level, and aptitude fit so two candidate builds can be compared quickly.
| Input | What it affects | Planning note |
|---|---|---|
| Five core stats | The largest part of the estimated evaluation score. | Stats above 1200 receive a higher planning weight because they usually represent a stronger late-game build. |
| Skill points value | Adds score for learned skills. | Use learned skills that matter to the race plan, not only cheap filler skills. |
| Unique skill level | Adds a small bonus for upgraded unique skill strength. | This helps compare finished builds without overstating one field. |
| Aptitude bonus | Represents distance/style fit and inherited suitability. | A high rating with poor aptitude can still perform badly. |
| Next rank gap | Shows how far the build is from the next visible threshold. | If the gap is small, a few efficient skills may matter more than raw stats. |
Transparent estimate
The calculator uses a visible planning formula so results are stable and explainable. Treat the output as a ranking aid, then validate important builds through repeated race simulations.
When This Tool Helps
Rating planning is useful when two builds are close and you need to know whether chasing a higher evaluation score is worth the tradeoff.
Rank threshold check
See whether a build is close enough to the next rank to justify extra skills or another stat-focused training turn.
Skill vs stat tradeoff
Compare a build with more raw stats against one with more learned skills before spending skill points.
Simulator prep
Use the rating estimate first, then run the same build in Umalator to make sure the higher score also wins more races.
Limits and Edge Cases
Evaluation score is useful, but it is not the same as race strength. Use this page to plan, not to replace game testing.
- The model is an estimate and does not claim to reproduce every official hidden scoring detail.
- Balance patches, scenario changes, and rank-threshold updates can change real in-game values.
- A high rating can still lose if the build lacks stamina, acceleration, recovery, or course fit.
- A lower-rated build may be better for Champions Meeting if its skills and race conditions are more reliable.
- Use repeated Umalator runs before making final competitive decisions.
