Upgrade is likely profitable within the time window you entered.
Formula: total cash = cash per second x multiplier x session seconds. Offline time is counted as a reduced 50% fan-made estimate. Net profit subtracts upgrade cost from the upgraded income gain.

How the profit estimate works

The calculator multiplies your current cash per second by your multiplier and session duration, then compares that against the upgraded income path. Offline duration is counted conservatively as a reduced estimate because exact offline rules can vary or change.

Best next step logic

A positive net profit means the upgrade should earn back its cost during the window you entered. A long break-even time means the upgrade still helps income, but it may not be the best use of cash before your next goal.

FAQ

What is the Sell Lemons Profit Calculator for?+

It estimates how much cash your current and upgraded income can produce over a play window, including a conservative offline estimate.

Is offline income exact?+

No. The fan-made model counts offline duration as a reduced estimate. Set offline duration to zero if you only want active-session planning.

What does net profit mean?+

Net profit is the extra cash after subtracting the upgrade cost from the upgraded income gain.

How do I use boost percentage?+

Enter the percent increase an upgrade or effect gives your income. For example, 25 means a 25% income boost.

Can this help with money guide decisions?+

Yes. Use it with the money guide to compare whether an upgrade pays back during your actual session length.
