Enter Base Pet Income
Copy the selected pet income and keep its unit consistent. Per-second input gives a per-second result. Expand abbreviations: use 1000000 for one million. Enter digits and a decimal point without currency symbols or commas.
Choose a baseline that does not already include the mutation you are adding. Using the final income of an already modified pet as an unmodified baseline can count the same bonus twice. If you cannot isolate the original rate, treat the input as a hypothetical starting value and keep that limitation with your comparison.
