This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own [π] Bike For Egg! session. It will not click the shop.
Upgrade payback
Upgrade payback
Estimate how many one-minute cycles a Money purchase needs if you already know the extra coins per second. Multiply that extra by 60 and enter it as extra Money per minute. The default shows a pet that adds 100 Money per second against a 50,000 Money price. Change both numbers to the shop price and the rate on your pet. This does not read your base, and it does not price Speed-only bike multipliers unless you convert that Speed into extra income yourself.
Payback cycles = upgrade cost Γ· extra profit per cycle, rounded up.
Pets earn every second. Extra per minute equals extra per second times 60. The default 6,000 per minute is 100 per second, against a 50,000 Money example price. Neither number is a drop rate.
