How to Use Carat Calculator Umamusume
The Carat Calculator Umamusume helps you plan your gacha resources so you always know exactly how many pulls you can do and how far you are from pity.
- Enter Current Carats and Pull Costs — Type your current carat balance. Set the single pull cost (default 150) and 10-pull cost (default 1500). Adjust these if your server uses different values.
- Set Pity and Target — Enter how many pulls you have already done on the current banner (your current pity count) and the pity threshold (default 200 pulls for spark). Optionally set a target pull count if you want to reach a specific number without necessarily hitting pity.
- Add Incoming Carats — Fill in your expected daily carats, any confirmed event or login bonus carats, and any planned purchase or pack carats. The Carat Calculator Umamusume sums all sources to calculate your total budget.
- Read the Results — The tool shows your total available carats, a pull breakdown (how many 10-pulls and single pulls you can do), pity status (whether you can reach spark), and an estimated number of days if you cannot reach pity yet.
Adjust the inputs freely to model different scenarios, such as saving for a future limited banner or comparing the impact of different purchase packs.
Formula & Theory — Carat Calculator Umamusume
The Carat Calculator Umamusume uses the following formulas:
Total Carats = Current Carats + Daily Carats + Event Carats + Purchase Carats
10-Pulls Available = floor(Total Carats / 10-Pull Cost)
Remaining after 10-Pulls = Total Carats − 10-Pulls Available × 10-Pull Cost
Single Pulls Available = floor(Remaining after 10-Pulls / Single Pull Cost)
Total Pulls Available = 10-Pulls Available × 10 + Single Pulls Available
Pulls Needed for Pity = max(0, Pity Threshold − Current Pity Count)
Carats Needed for Pity = max(0, Pulls Needed for Pity − Total Pulls Available) × Single Pull Cost
Carats Needed for Target = max(0, Target Pulls − Total Pulls Available) × Single Pull Cost
Days to Pity = ceil(max(0, Carats Needed for Pity − Event Carats − Purchase Carats) / Daily Carats)| Symbol | Meaning |
|---|---|
| Total Carats | Sum of all available and incoming carat sources |
| 10-Pull Cost | Carats required for one 10-pull (default 1500) |
| Single Pull Cost | Carats required for one single pull (default 150) |
| Pity Threshold | Number of pulls required to guarantee pity/spark (default 200) |
| Current Pity Count | Number of pulls already done on the current banner |
Assumptions and Limits
The Carat Calculator Umamusume assumes all input values are known. Pull costs, pity thresholds, and event reward amounts vary between servers (JP, KR, CN, EN) and may change with game updates. Always verify the current values in-game before making spending decisions.
