Sell Lemons Rebirth Calculator
Enter your current run stats to estimate whether rebirthing now pays back inside your target play window.
Formula assumptions
How the estimate works
The launch calculator treats each gained investor as an estimated multiplier delta of 0.015, then compares payback against your target time window.
| Input | How it is used | Confidence |
|---|---|---|
| Investor gain | Expected investors after rebirth minus current investors. | estimated |
| Multiplier delta | Investor gain multiplied by 0.015. | estimated |
| Payback | Current cash divided by estimated added income per minute. | estimated |

Recommendation logic
A rebirth is favored when investor gain is meaningful and estimated payback fits your session window.
Formula assumptions
The launch estimate treats each investor gained as a small multiplier delta. Replace this after verified gameplay data exists.
How to use the result
Read the action, then check the reason. A Rebirth now result means the estimate fits your session window; Wait means either the gain is small or payback is too slow; Check manually means the inputs do not support a reliable estimate.

- Investor gain
- Estimated payback
- Reason
- Warnings
Example: strong reset
A run with 20 current investors and 70 expected after rebirth produces a gain of 50. With 1,000,000 cash and 2,000 income per second, the launch estimate pays back inside a 30 minute target window.
Example: weak reset
A run with only a few extra expected investors should usually wait unless you are testing. The calculator intentionally treats tiny gains as weak even if the reset button is available.
When the calculator is not enough
Do not rely on the estimate when you are about to buy a critical power, enter Evolution, test a new update, or compare permanent purchases. In those cases, screenshot the in-game preview first.
- Before expensive powers
- Before Evolution
- After a patch
- When preview numbers look unusual
Next tool upgrades
The calculator can become more accurate after collecting verified investor formulas, power costs, and income samples. Until then, it is most useful as a structured decision prompt.

FAQ
Quick Answers
Is the rebirth calculator official?
No. It is an estimated fan-made planning tool with visible assumptions.
Where are my calculator inputs stored?
Inputs are stored only in your browser localStorage so you can revisit the page without logging in.
What should I do if the result says Check manually?
Fix missing or invalid inputs, then compare the output against your in-game rebirth preview.
Why does the calculator use a target time window?
A rebirth can be mathematically positive but still feel bad if it takes longer than your play session to recover. The target window makes that tradeoff explicit.
