Prestige calculator
Infinity Points from your highest antimatter, Eternity Points from your Infinity Points, and the amount a target needs.
Your numbers
Infinity Points
IP = floor(10^(log10(antimatter) / 308 − 0.75) × multiplier)
Eternity Points
EP = floor(5^(log10(IP) / 308 − 0.7) × multiplier); you can Eternity from 1.80e308 IP.
How this works: these are the game's own formulas. Infinity Points use the highest antimatter you reached this Infinity: once Infinity is broken you get 10 to the power of (log10 of it divided by 308, minus 0.75), times your IP multiplier, rounded down; before that, a flat 308 divided by the divisor. Achievement 103 lowers the divisor to 307.8 and Time Study 111 to 285, and the smallest one applies. Eternity Points use the highest IP this Eternity plus the IP you would gain now: 5 to the power of (log10 of it divided by 308, minus 0.7), times your EP multiplier, rounded down. Take the multipliers from the game's multiplier tab. Celestial Realities, Doomed and glyph alterations change these formulas and are not covered here.
