The formula is visible
Spendable equals the larger of zero or budget minus reserve. Safe attempts are whole spendable units divided by the cost, with the remainder left visible.
Mutant Plants Base Defense Budget Calculator
Enter the balance and per-attempt cost shown in the live game. The calculator protects a reserve, counts whole attempts, and checks a target without guessing currency names, roll probabilities, pity, rewards, or upgrade effects.

Calculated locally
Plant roll budget
Enter a non-negative budget and a cost greater than zero. Use the live interface for both values.
This calculation runs in your browser. It does not request a Roblox login, predict results, or send the values to the game.
Why defaults stay blank
Roll and upgrade costs can change. A blank field tells you to use the current server instead of an old or cross-game number.
What the tool cannot predict
It does not know plant rarity, Secret chance, pity, merge gains, reward amounts, or the best stopping point. It only performs budget arithmetic.
Budget questions
What does this calculator return?
It returns spendable resources, safe whole attempts, remainder, one-more-attempt shortfall, and whether your target fits while preserving the reserve.
Does it use plant odds or pity?
No. It intentionally excludes unpublished probability and guarantee systems.
Which cost should I enter?
Enter the cost displayed for the exact roll, upgrade, or repeated action on your current server.
Does it need my Roblox account?
No. The arithmetic runs locally in the page and requires only the numbers you choose to enter.
