This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own [NEW] Jujutsu Farm session. It will not click the shop.
Drop probability
At least one successful open
Estimate the chance of at least one success across repeated cube opens. You supply the percent. This worksheet does not contain a hidden drop table.
Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.
Jujutsu Farm does not publish per-cube drop rates. Type a percent you can read on a stall panel. The 10% default is a worksheet example, not a game rate. The result is the chance of at least one success if every open is independent.
Upgrade payback
Upgrade payback
Estimate how many Orb cycles a cash upgrade needs before the extra income covers its cost. Enter the numbers shown on your upgrade button.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
Read the upgrade cost and the income change from your own upgrade button. One recorded Star Nanami moved from $18.50K/Orb at level 1 to $1.90M/Orb at level 29, but the cash spent on those clicks was not published. The defaults are not that session's costs. Orb length is not published, so set the minutes to the gap you actually see.
