Which calculator values come from the player?
All game-specific costs, income rates, quantities, durations, projected rates, and rebirth assumptions are entered by the player. Numeric fields start blank.
Which formulas and time conversions are used?
Income uses multiplication, payback and recovery use positive-denominator ratios, and durations use universal seconds, minutes, hours, and days conversions shown on the page.
How are zero, invalid, and missing inputs handled?
The calculator identifies missing fields, preserves valid input, reports zero-divisor results as unavailable, and never displays NaN or Infinity.
Are rebirth results official recommendations?
No. They are scenarios from assumptions you enter. The tool does not know an official multiplier, threshold, reset scope, reward, or optimal rebirth time.
