For each upgrade, calculate next minus current, divide the gain by current for percentage change, and divide by cost for arithmetic efficiency. For a cash target, divide remaining cash by measured cash per throw, then divide required throws by throws per minute.
Enter visible values and keep unlike units separate
For each option, record a clear name, current value, next value, and cost exactly as shown in the current server. Do not invent a Luck conversion or translate an unpublished effect into cash. If one option changes a percentage and another changes a count, the calculator can describe each option's relative gain, but it cannot prove the effects are interchangeable. Save the world, event condition, and date with the inputs. The tool is designed to compare arithmetic the player can see. It does not pull a hidden item table, drop rate, or upgrade curve from the game.
Calculate absolute, percentage, and cost efficiency
Absolute gain equals next value minus current value. Percentage gain equals absolute gain divided by current value, multiplied by one hundred; if the current value is zero, treat percentage as unavailable rather than dividing by zero. Arithmetic efficiency equals absolute gain divided by upgrade cost. These outputs answer different questions. Absolute gain shows size in the option's own unit, percentage gain shows relative change, and gain per cost shows how much visible change is purchased per unit of cash. None of them knows whether a Luck increase produces a particular rare item, so label the result as an input comparison rather than a hidden-meta ranking.
Confirm the winner with a controlled session
A calculated efficiency lead should become a test, not an automatic purchase rule. Buy or trial one option, then repeat the same fixed-throw or fixed-time session used for the baseline. Keep world, fountain, event state, and sell timing stable. Compare ordinary cash gain, throws completed, and any visible change tied to the option. If the real session does not improve or the difference is smaller than ordinary variation, collect more samples before spending heavily. When two options use unrelated units, let the player's current goal decide: cash pace, result quality, or another visible outcome. The calculator cannot collapse every goal into one score.
Build a cash target from your own rate
Enter current cash, target cash, measured cash per throw, and measured throws per minute. Remaining cash equals target minus current, with negative results treated as zero. Estimated throws equal remaining cash divided by cash per throw. Estimated minutes equal required throws divided by throws per minute. Use rates from several comparable ordinary sessions, not the highest lucky run. The result is a schedule built from personal evidence. It does not forecast rare drops, event changes, pauses, or future upgrades. Recalculate after any purchase or world change because the old rate may no longer describe the current loop.
Use a hypothetical example without turning it into game data
Suppose a player—not the game—records 100 as a current visible value, 125 as the next value, and 5,000 as cost. The absolute gain is 25, percentage gain is 25 percent, and arithmetic efficiency is 0.005 gain units per cost unit. A second option with different units must be interpreted separately even if its efficiency number looks larger. Likewise, if a personal session produces 2,500 cash per throw at 12 throws per minute, the planner may use those inputs for that player only. These numbers are examples of the formulas, not verified Throw a Coin prices, rates, or upgrade levels.
Discard stale inputs and preserve the evidence boundary
Start a new worksheet after a balance update, event change, new world, altered fountain, or major upgrade. Do not combine event-boosted and ordinary sessions. Mark code rewards separately because BIGBANG's creator-listed string does not provide a supported reward value in the official description. If an output requires a hidden odds table or a guessed item value, the correct result is unknown. Keep a dated snapshot of inputs and the session used to confirm them. The planner is successful when it helps the player make one transparent decision and later reproduce why, not when it pretends to solve every unpublished system.

What this guide does not assume
Both tools perform arithmetic only on player-entered visible values. They do not model hidden Luck, loot odds, item values, mutations, world gates, code rewards, or future event effects, and hypothetical examples are not game facts.
Refresh trigger: Refresh when the official upgrade interface or loop changes, the specialist tool formulas change, or reproducible evidence establishes new input units, cost behavior, or a verified code reward that affects planning.
