Transparent formula
Spendable equals max of zero and budget minus reserve. Safe attempts equals the floor of spendable divided by current cost. The remainder stays visible.
Magic Loot Calculator: Plan Attempts and Protect a Reserve
Enter the balance and cost shown in your current server. The tool protects a reserve, calculates whole attempts, and checks a target using transparent arithmetic only. It does not predict loot, boss rewards, potion effects, rebirth gains, or hidden odds.

Values from your server
Set a visible spending limit
Use only a current cost displayed by the game. Leave the field blank when the action has no transparent cost.
Calculated locally
Custom attempt budget
Enter a non-negative budget and a cost greater than zero. Use the value shown by the current game.
No Roblox login is used. Values stay in your browser and results depend entirely on what you enter.
Why the cost starts blank
A blank field is safer than a value copied from another update, server, action, or Roblox game. Read the current interface first.
What the tool cannot predict
It does not estimate loot rarity, drop rates, boss rewards, potion effects, event availability, rebirth multipliers, or the best subjective stopping point.
Calculator questions
What does this calculator do?
It converts a budget, protected reserve, visible cost, and target into whole safe attempts, remaining resource, and any target shortfall.
Does it know drop rates or rebirth multipliers?
No. The tool performs transparent budget division and never estimates hidden odds, effects, rewards, or multipliers.
Which values should I enter?
Use the balance and cost shown in your current Magic Loot server. Leave a cost blank when the game does not display one.
Are my values sent to Roblox or this site?
No. The calculation runs locally in your browser and does not request a Roblox login or account detail.
