Cost of Owning a Cat Calculator
Estimate how much a cat costs per month, per year, and over time — including one-time setup costs, recurring expenses, and optional emergency savings.
Quick answer
What you’ll get:
- Monthly average (recurring + yearly items split by 12)
- Yearly average and total cost over your chosen time period
- First-year cost (one-time setup + 12 months of recurring)
Inputs
Common choices: 5–10 years.

Is this estimate accurate?
This calculator is designed for planning and budgeting. Your real cost depends on your cat’s age, health, diet, lifestyle (indoor/outdoor), and local prices. The best approach is to enter your current monthly costs and your typical annual vet spend, then add an emergency buffer if you want a safer plan.
How this calculator works (formulas)
This calculator combines one-time costs (setup) with recurring costs (monthly + yearly items). Yearly items are split into monthly equivalents to show an “average month.”
Definitions
- One-time total = adoption + initial vet + spay/neuter + supplies
- Monthly total = food + litter + treats/toys + misc + insurance
- Yearly total = routine vet + preventives + boarding/sitter
- Emergency per year = optional yearly savings buffer
Core formulas
- Average monthly = monthly total + (yearly total / 12) + (emergency / 12)
- Average yearly = average monthly × 12
- First-year cost = one-time total + (average monthly × 12)
- Total over N years = one-time total + sum of yearly recurring costs over N years (inflation applied if set)
Note: If inflation is set to 0%, recurring yearly costs are constant. If inflation is greater than 0%, we increase recurring costs each year by the chosen percentage.
FAQ
What is the average monthly cost of a cat?
It depends on food quality, litter type, vet care, and whether you pay for insurance. Use the monthly, yearly, and emergency inputs to match your situation — the monthly average includes yearly items split across 12 months.
What costs should I include for a realistic budget?
Include food, litter, routine vet visits, preventives, and a small emergency buffer. If you travel, add boarding/sitter. If you prefer predictable costs, include insurance (or increase your emergency fund).
Does the calculator include one-time costs?
Yes. Adoption/purchase, initial vet visit, spay/neuter (if needed), and supplies are added once. This affects the first-year cost and the total cost over your selected time period.
How does inflation work here?
If you set inflation above 0%, the calculator increases recurring yearly costs each year by that percent (one-time costs are not inflated). Leave inflation at 0% for a simple estimate.

Tip: After a few months, update inputs based on your real spending for a more accurate estimate.
