Total Annual Cost = Food + Vet + Grooming + Insurance + Toys & Treats + Boarding + Misc
Monthly Average = Total Annual Cost ÷ 12
Remaining Lifetime Cost = Total Annual Cost × (Expected Lifespan − Current Age)

Costs vary significantly by pet type, size, breed, and geographic location. Vet costs tend to increase as pets age.
