1. Estimate food costs
Use the normal monthly cost of food, treats, and any special diet items.
2. Average periodic care
Convert annual checkups, vaccinations, grooming visits, and preventive treatments into monthly amounts.
3. Add protection and supplies
Include insurance premiums, litter or bedding, toys, replacement equipment, and routine accessories.
4. Account for outside care
Average expected boarding, walking, daycare, or pet-sitting costs across the year.
5. Build a reserve
Enter a monthly emergency-fund contribution separately from expected routine care.
6. Review the annual commitment
Use the annual result when comparing pet ownership with other long-term household priorities.
