Formula
Spendable equals the larger of zero or budget minus reserve. Safe attempts equal spendable divided by cost, rounded down.
Uma Fighters Attempt Budget Calculator
Enter values displayed in your current game session or any repeatable activity. The calculator protects a reserve and shows how many attempts fit. It does not know hidden rates, character strength, pity, or unpublished costs.

Your current values
Set a clear limit
Read the balance and cost from the current interface. Leave cost blank until the game shows a value you can verify.
Calculated locally
Custom attempt budget
Enter a non-negative budget and a cost greater than zero. Use a cost visible in the current game or activity.
No Roblox login is used. The calculation stays in your browser and depends entirely on the values you enter.
Why cost starts blank
No verified universal cost was available, and alpha values may change. A blank input avoids copying a number from another game or update.
What it cannot predict
The tool cannot rank characters, predict outcomes, reveal hidden odds, or decide whether an activity is worth the cost.
Calculator questions
What does the calculator do?
It converts your balance, visible per-attempt cost, reserve, and target into transparent budget results.
Does it know character odds or pity?
No. It performs arithmetic only and does not claim access to hidden or unpublished systems.
Where should the inputs come from?
Use values shown by the current game or the repeatable activity you are planning. Do not copy costs from another title.
Are the values sent to Roblox?
No. The calculation runs locally and never asks for your Roblox account or password.
