Sell Lemons Rebirth Calculator

How to Use This Calculator

Enter your Current Cash and Income per Second from the game. Set the Rebirth Multiplier Bonus (how much the multiplier increases per rebirth) and your Current Rebirth Multiplier. Estimate your Rebuild Time (how long to recover after rebirth) and a Target Cash goal. The calculator tells you whether to rebirth now or wait.

Formula and Estimate Logic

Post-Rebirth Income = Base Income × (Current Multiplier + Bonus). Recovery Time = Current Cash ÷ Post-Rebirth Income. Break-Even = time for the new multiplier to outperform your current state. The calculator recommends REBIRTH when the recovery time is within your rebuild window and the long-term gain is positive.

When to Use This Calculator

Use this calculator every time you consider rebirthing. It is especially useful in mid-to-late game when rebirth decisions become less obvious. If you are unsure whether to rebirth or keep earning, the calculator gives you a data-driven recommendation based on your specific situation.

Common Mistakes

• Rebirthing too early when income is very low - the multiplier bonus has minimal impact
• Waiting too long between rebirths - each rebirth compounds future earnings
• Not factoring in rebuild time - a fast rebuild makes frequent rebirths worthwhile
• Forgetting that rebirth resets cash and upgrades, not just multipliers
