Use comparable inputs
Enter each option’s current value, next value, and cost exactly as the game shows them. Do not compare two unrelated units as if the result were a hidden ranking.
Transparent progression math
Upgrade Comparator
Compare two Throw a Coin upgrades using your own current values, next values, and costs. Every formula is visible and no hidden game curve is assumed.
YOUR NUMBERS
Compare two upgrades
Use the same unit within each option. The tool compares arithmetic only; it does not guess hidden drop odds.

Formula: gain = next − current; percentage gain = gain ÷ current × 100; efficiency = gain ÷ cost.
Read three outputs
Absolute gain shows size, percentage gain shows relative change, and gain per cost shows arithmetic efficiency. A close result is a reason to test in game.
Recalculate after change
Buy one upgrade, measure a new baseline, and enter the next visible values. Event boosts and world changes deserve separate comparisons.
Calculator questions
What does the Throw a Coin upgrade calculator compare?
It compares absolute gain, percentage gain, and gain per unit cost for two player-entered options.
Does the calculator know the hidden Luck formula?
No. No official public curve was found, so the tool uses only the values you enter.
Can I enter very large numbers?
Yes. Decimal arithmetic supports values far beyond ordinary safe JavaScript integers.
Is the higher-efficiency option always best?
No. The result compares your inputs only. Your immediate world, collection, or cash goal can still change the decision.
