How to use the calculator
- Enter your current income per second from Sell Lemons. If the game already shows a fully boosted rate, leave the multiplier fields at
1so you do not count the same bonus twice. - Set your offline time in hours. Use decimals for shorter windows, such as
0.5for 30 minutes. - Add a base multiplier, boost multiplier, or Investor bonus only when that value is not already included in your income rate.
- Add a target cash amount if you want to see about how long the current rate needs to reach it.
The result is an estimate from the numbers you enter: effective income per second, income per hour, total offline earnings, and time to target. Treat it as planning math, not a promise that the game will return the exact same amount.
The calculator multiplies your entered income per second by your optional multipliers, then multiplies that effective rate by your offline time. The target result uses the same effective hourly income to estimate how long it takes to reach the cash goal.
Use the estimate before logging off, before waiting for a target upgrade, or after buying a manager that changes your idle rate. It is most useful when you update the income field after each major purchase instead of reusing an old rate.
Timed boosts may expire while you are away, your visible income rate may already include some bonuses, and Sell Lemons may apply rules that are not visible from public data. If the number looks too high, check whether you counted a multiplier twice.
FAQ
Does this calculator know the exact Sell Lemons offline formula?
No. It uses the income rate, time, and multipliers you enter. That keeps the result honest when hidden formulas, boosts, caps, or update changes are not fully verified.
Should I enter my income before or after multipliers?
Use the rate you want the estimate to start from. If your in-game rate already includes a multiplier, leave that multiplier field at 1 so the calculator does not apply it again.
Do boost timers count while I am offline?
Treat boost timers carefully. If a boost may expire before you return, either leave it out or use a shorter offline window that matches the remaining boost time.
Does the calculator save my Sell Lemons stats?
No. The inputs are only used in your browser for the estimate.
