Throw a Coin Upgrade Calculator
Compare two upgrades in the same unit using your current costs and observed gains. The result is a planning aid—not an official luck or drop-rate formula.
Compare two upgrades
This tool compares values you enter. It does not convert luck into hidden drop odds.
Result
Enter both options to compare
Based on your observations · high-confidence arithmetic · not a drop-odds formula · no values are sent to analytics.
How to get a useful comparison
- Choose one shared gain unit, such as cash per minute or luck points shown by the game.
- Enter each upgrade's current cost and the gain you can actually observe.
- Keep both goal weights at 1 unless one type of progress matters more to you.
- Re-enter values after an upgrade because costs and gains may change.
What the result does not claim
The calculator does not know hidden rarity odds, potion stacking, VIP effects, server bonuses, or a universal conversion between luck and cash. Compare unlike goals separately.
Upgrade calculator questions
Is the calculator exact?
The arithmetic is exact for the values entered, using BigInt-backed decimal comparisons. The result is still a planning estimate because costs and gains come from your observations.
Can it calculate exact drop odds?
No. The current public sources do not provide the complete odds, modifier and pity data needed for a safe drop-odds calculator.
What number suffixes are supported?
The tools accept full numbers and K, M, B, T, Qa, Qi, Sx, Sp, Oc, No and Dc suffixes without converting huge values to JavaScript Number.
Do goal weights come from the game?
No. A goal weight is your preference and defaults to 1. It should not be presented as a luck, value or cash coefficient.
