How the numbers are calculated
Estimated income = base income × mutation bonus × size bonus × quantity. Turn on ×2 Money pass if you own it to double this estimate.
Golden and Rainbow together give a ×5 mutation bonus. The size bonus comes from your pet's weight compared with its species reference weight.
Choose In-game income to use the final amount your pet earns per second. We apply quantity only to this rate. Update it when a temporary boost ends.
Minute, hour and day totals assume the same income rate throughout. Your goal time uses the amount still needed after subtracting your current balance.
Weight estimates leave out temporary boosts and may differ from the game. If a reference weight is missing, use your pet's final in-game income.

How to use the calculator
Add a separate row when two pets have different weights or mutations. This keeps each pet’s contribution clear. Your total updates as you change the inputs. Check earnings per second, minute, hour, or day. Under Earnings in, enter a session length to see how much that time could earn.
Already know your pet’s income?
Choose In game income and enter the final income per second shown in game. Include any pass or boost already reflected in that figure.
This mode applies quantity only. For example, three identical pets earning $10M/s each give a total of $30M/s. Update the entered rate when a temporary boost ends.
How weight and mutations affect earnings
Estimated income uses your pet’s base income, mutation bonus, and size bonus. Quantity and the Money pass then apply to that result.
Mutation bonuses add together. Golden gives ×2.5, while Rainbow gives ×3.5. Together, their combined multiplier is ×5. Suppose a pet earns $100/s at its reference weight. Golden and Rainbow take that estimate to $500/s. With the ×2 Money pass enabled, it becomes $1,000/s.
Weight uses a separate size bonus. The calculator compares your pet’s weight with its species reference weight. At twice the reference weight, the community formula gives roughly a ×1.53 size bonus.
Weight estimates use community reference values. Use the final in-game income method when you want totals based on your pet’s current displayed earnings.
Work out when you can afford your target
Enter the amount you need under Target amount. Then add the money you already have under Current balance. For example, a 1B target with 400M already saved leaves 600M to earn. At a steady $2M/s, that takes five minutes. If you are saving for another egg, you can follow recent egg stock reports while checking your progress.
Check whether an upgrade is worth the cost
Select Save total to compare before changing your pen. Then try another pet, weight, or mutation. The comparison shows your extra income per second and hour. Add the upgrade’s cost to see how long the extra income would take to earn it back.
For example, an upgrade costing 600M that adds $20M/s has a payback time of 30 seconds. Change one thing at a time to see what made the difference. When comparing a replacement pet, remove the old pet’s row from your new setup.
