Key Takeaways
Estimates only. Exact rebirth cost and multiplier values vary by game version -- confirm in-game before deciding.
The calculator compares two futures: grinding without rebirth and grinding after rebirth. Without rebirth, your income stays at the current rate and you keep every dollar earned. After rebirth, you spend the rebirth cost and gain a permanent rebirth multiplier that raises your income going forward.
The income boost per minute equals your current income times the multiplier gain divided by your current multiplier. For example, if you earn $2,500/min at a 1x base and gain +0.5x from a rebirth, the income boost is $1,250/min. Break-even is the rebirth cost divided by that boost: a $25,000 rebirth at +$1,250/min takes around 20 minutes to recover.
Rebirth makes sense when break-even is shorter than the time you plan to keep playing. If you are closing the game in 30 minutes and break-even is 45 minutes, grinding is better. The planning horizon buttons (30/60/120 min) let you match the calculator to your actual session length.
For context on how upgrades affect your income per minute, the upgrade payback planner covers roller speed, paint tier, and expansion buys in detail. Knowing your income before opening this tool gives more accurate break-even results.
"Rebirth worth it" is not a binary question. A rebirth with 30-minute break-even is clearly better in a 2-hour session than one with 90-minute break-even. The calculator shows the net gain over your horizon so you can compare scenarios rather than just getting a yes or no.
One genuine limitation: the model assumes you re-enter your current upgrade state immediately after rebirth. In practice you need to re-grind upgrades, which adds recovery time. The calculator's verdict is a best case. Budget a few extra minutes when deciding close calls.
The result banner shows the verdict ("Rebirth now" or "Keep grinding"), the break-even time, and the net gain over your chosen horizon. A green outline means rebirth pays back within your window.
Break-even is how many minutes of the boosted income rate it takes to recover the rebirth cost. A longer break-even is not always bad: if your horizon is 2 hours and break-even is 40 minutes, you still come out ahead by a large margin. The net gain number below the verdict shows the actual dollar difference.
Three situations produce this outcome: the multiplier gain is too small relative to the rebirth cost, your current income is low (early game), or your planning horizon is shorter than the break-even time. Changing any one of those inputs can flip the verdict. Try the 120-minute horizon to see whether a longer session changes the recommendation.
Once you know your next rebirth multiplier is worth it, the upgrade order guide shows how to reach the rebirth cost threshold as fast as possible by picking the shortest-payback upgrade at each step.
These three static examples show how break-even and net gain shift across game stages. Load them into the calculator using the preset buttons, or adjust the numbers to match your own situation.
Income $2.5K/min, Rebirth cost $25K, Mult 1x to 1.5x
Income boost is +$1.25K/min. Break-even around 20 minutes. Net gain over a 60-minute session is about $50K. Rebirth early and often; the cost is low and the multiplier compounds quickly.
Income $50K/min, Rebirth cost $500K, Mult 3x to 4.5x
Income boost is +$25K/min. Break-even around 20 minutes again. Net gain over 60 minutes is about $1M. Higher costs are offset by higher income rates, keeping break-even short.
Income $100K/min, Rebirth cost $8M, Mult 10x to 11x
Income boost is only +$10K/min. Break-even is around 800 minutes, far beyond any normal session. Keep grinding here and save rebirth for when the cost drops or the multiplier gain increases.
Paint tier affects income significantly. See the best paints comparison for multiplier values by tier, and the paint tier list for an S-to-C ranking of all six paints. Active codes can also add a cash boost that changes your income rate before you run the rebirth calculation.
Short answers for launch-day Paint My Keyboard planning.
Rebirth when your break-even time is shorter than your planning horizon. If the rebirth cost divided by your income boost comes out to 20 minutes and you plan to play for at least an hour, rebirth makes sense. Use the calculator above to check your specific numbers.
It depends on the multiplier gain relative to the cost. A small gain on a high rebirth cost produces a long break-even time, which is rarely worth it in a short session. A large multiplier gain at a reasonable cost can pay back in under half an hour.
Rebirth resets your progress but grants a permanent income multiplier that applies to all future earnings. Each subsequent rebirth stacks on top of earlier ones, so your multiplier grows over time.
The rebirth cost varies by game version and your current stage. Early rebirths cost far less than later ones. Check the in-game rebirth menu for the exact current cost -- the number shown in this calculator is an estimate you can adjust to match.
Rebirth resets most progress including cash and upgrade levels, but the permanent rebirth multiplier carries over. This is why break-even time matters: you need enough future income from the new multiplier to recover what you spent on the rebirth.
The rebirth multiplier is a permanent income boost earned by completing a rebirth. It stacks additively with previous rebirths, so a 1x base multiplier plus a 0.5x gain becomes 1.5x total. Higher multipliers mean your income scales faster after every rebirth cycle.
Rebirth requires reaching the cash threshold shown in the in-game rebirth menu. The exact rebirth requirements change as the game updates, so check inside the game rather than relying on third-party guides for the precise number.
