Umamusume Race Bonus Calculator
Estimate how support-card race bonus, optional scenario bonus, race count, and wins change the value of a training run before you compare the build in the Uma Race Simulator.
Calculate Your Race Bonus Setup
Enter your planned races, wins, goal races, and support-card race bonus. The calculator returns a practical bonus-weighted score you can use to compare two training plans. It is designed for planning, not for replacing exact in-game scenario formulas.
Estimated Output
Adjust the inputs to compare race-heavy and training-heavy plans.
Example Plan
A race-heavy build with 35 training races, 5 goal races, 28 wins, and four 10% race-bonus support cards produces a stronger event-point plan than the same race count with low-bonus cards.
- Use the score to compare two support decks before starting a育成 run.
- Keep wins realistic: a plan that assumes every optional race is won can overstate value.
- After picking a plan, test the final stats and skills in the Uma Race Simulator.
How to Use the Umamusume Race Bonus Calculator
Use this calculator before you commit to a support deck or a race-heavy training plan. It gives a quick directional answer: whether your race bonus is high enough to justify extra races, or whether the deck should focus on stats and skills instead.
1. Enter your race count
Start with the optional races you expect to run. Add required goal races separately because they are usually not optional and should not be evaluated the same way as extra event-point farming races.
2. Add realistic wins
Wins improve the score, but the number should match the character, scenario timing, and distance aptitude. If you are testing a risky schedule, lower the expected win count.
3. Add support-card bonus
Enter the race bonus percentage from each support card. A deck with high race bonus often rewards more racing, while a low-bonus deck may need fewer races and more training turns.
4. Compare plans, then simulate
Use the output to compare plans. Once you choose a schedule, open the Uma Race Simulator to test whether the final stats, stamina, strategy, and skills still perform well.
What the Calculator Measures
The tool uses a transparent planning score. It intentionally avoids pretending to know every hidden scenario modifier, because Umamusume scenarios can change reward rules, caps, and rounding. The goal is to compare plans consistently.
| Input | What it means | How to use it |
|---|---|---|
| Training races | Optional races you choose during training. | Raise this when you are planning a race-heavy event-point run. |
| Goal races | Required races that happen as part of the character or scenario route. | Keep them separate so the plan does not overvalue optional racing. |
| Expected wins | How many races you expect to win. | Use a realistic estimate instead of assuming perfect outcomes. |
| Support-card bonus | Race bonus percentages from your support deck. | Add each card separately to compare deck variants. |
| Scenario bonus | Extra race value from a scenario or rule set. | Leave it at 0 unless the scenario clearly provides an extra modifier. |
Planning Formula
The visible score is: base race value multiplied by total race bonus. It is best used as a comparison score between two plans, not as an exact in-game reward guarantee.
When This Tool Helps Most
Race bonus matters most when you are deciding between support cards that look similar on stats but differ in event-point efficiency.
Deck comparison
Compare a high-race-bonus deck against a stronger stat deck before deciding which support cards to borrow or use.
Race-heavy schedules
Estimate whether adding more optional races is worth the lost training turns in your current scenario plan.
Simulator preparation
After planning race value, use Umalator to verify that the resulting Speed, Stamina, Power, Guts, Wisdom, and skills can still win.
Limits and Edge Cases
The calculator is intentionally conservative. It helps with planning, but it does not claim to reproduce every scenario's internal reward table.
- Scenario-specific caps, hidden rounding, event choices, and balance patches can change exact rewards.
- A higher race score is not always better if the build loses too many training turns or misses key skills.
- Support cards with lower race bonus may still be better if they provide stronger stats, hints, friendship training, or recovery events.
- Use the output together with race simulation results, not as the only decision point.
