Uma Musume Race Calculator

Compute your final Uma rating with stat scores, character presets, aptitude-aware skill values, unique bonus, and full rank ladder support.

How to Use the Uma Musume Rating Calculator

Follow these five steps to calculate accurate rating points and rank progression.

  1. Load a character preset

    Search a Uma preset to preload that character's base stats and aptitudes for the currently selected star level.

  2. Adjust final stats

    Refine Speed, Stamina, Power, Guts, and Wisdom after loading a preset. The calculator supports values up to 2500.

  3. Pick star and unique level

    Select star rarity and unique skill level to apply the correct unique bonus multiplier.

  4. Add acquired skills

    Select skill types and names, including IUS and Evo skills. Aptitude-linked skills automatically switch score buckets.

  5. Review rank and next target

    Check total score, current rank, score breakdown, and points needed to reach the next rank tier.

Case Studies & Rating Checks

Three sample builds show how stat growth, aptitudes, and skill picks shift final rating.

  1. Preset first, then polish

    Loading a character preset gives you the correct starting panel quickly, then small stat edits reveal whether the build can cross the next badge threshold.

  2. Aptitude bucket upgrade impact

    Upgrading Medium aptitude from B to A raised several linked skills from average to good buckets, adding over 300 skill points.

  3. IUS slot optimization

    Replacing two low-value normal skills with one stronger IUS line improved total skill score while using fewer slots.

Uma Musume Rating Calculator FAQ

Why can the same skill show different points?

Some skills are aptitude-linked. Their score bucket changes with your current grade (S/A, B/C, D/E/F, or G).

Does this calculator support IUS skills?

Yes. IUS skills are available in the skill type selector and contribute directly to total skill score.

What stat range is supported?

Each base stat supports 0 to 2500. Values outside this range are clamped for stable calculations.

How is unique bonus calculated?

Unique bonus uses star-based multipliers: 1-2 stars use x120, 3-5 stars use x170.

How is total rating calculated?

Total rating = stat score sum + unique bonus + selected skill score sum.

Which ranks are included?

The rank ladder is fully supported from G through LS24, including UE, UD, UC, UB, UA, US, and Legend tiers.

How do I reach the next rank faster?

Improve stats with the highest marginal gain first, then replace low-value skills with high bucket-match skills.

Do templates change my skill list?

No. Character presets load base stats and aptitudes, but skills are still selected manually in the skills panel.

Can I compare two builds quickly?

Yes. Keep one build in place, note total score and rank, then swap stats or skills to measure the delta.

What does MAX mean in next-rank?

MAX means your score is already in the highest tier currently defined by the calculator thresholds.
