The calculator uses the numbers you enter. The calculator turns daily routine-care minutes into weekly hours and adds the extra hours. From the sitter-day count it subtracts a share of routine care, assuming a 30-day month. The result compares the hours that remain with the time you can give and shows spare time or a shortfall. Food and vet cost sit in the result grid and are not in the primary result. In the first example the result is 1.6 hours of spare pet-care time in a week.
The five form fields are routine care, extra hours, hours you can give, sitter days, and food and vet. Care hours means: Routine-care minutes turned into a week, then increased by the extra hours. After subtracting sitter cover, the calculator compares that need with the hours you can give. In the first example the result is 1.6 hours of spare pet-care time in a week. Sitter days means: Days in a month when someone else takes over routine care. The calculator treats them as a share of a 30-day month and subtracts them only from routine care, not from the extra hours. Food and vet means: The monthly cost. It appears in the result grid and does not change spare hours or the shortfall.
The second example gives 5.5 hours of spare pet-care time in a week. The third example gives 7.6 hours of missing pet-care time in a week. 40 minutes of routine care a day is 4.7 hours in a week. Two extra hours give 6.7 hours of need. Two sitter days in a 30-day month cover part of the routine care. 6.4 hours fall on you, and you can give 8. The result is 1.6 hours of spare pet-care time in a week.
The calculator does not replace a vet and does not judge the animal. It does not build a walking timetable. The people count is optional and does not change the main result.
