Savings time and optional break-even
Karinderya upgrade goal calculator
Use your current Cash, the displayed upgrade price and a measured profit rate to estimate how long the goal takes.
The calculator subtracts current Cash from the displayed upgrade cost, never below zero, then divides the remaining amount by measured profit per minute. An optional orders-per-minute rate estimates completed orders during the wait. An optional tested profit boost estimates how long the purchased upgrade takes to repay its full cost.

Formula
How the result is calculated
- 01
Remaining Cash = max(upgrade cost − current Cash, 0).
- 02
Minutes to goal = remaining Cash ÷ positive profit per minute.
- 03
Expected orders = minutes to goal × measured orders per minute.
- 04
Post-upgrade break-even = upgrade cost ÷ tested profit boost per minute.
Limits
What this tool cannot prove
- The calculator cannot supply an unknown current price.
- A projected boost is not a verified game effect without a comparable test.
- Idle time, restocks and changing queues can affect the measured rate.

Frequently asked questions
What if profit per minute is zero?
If Cash is still required, time to goal remains unknown instead of displaying Infinity.
Is the expected profit boost required?
No. It is optional and should come from a comparable before/after test.
Can I use this for the Chiller?
Yes, when the current server shows a price. The calculator does not supply an unverified Chiller value.
