FAQ
Is pet insurance worth it?
It converts a low-probability five-figure bill into a predictable monthly cost. If you would struggle to pay a $6,000 emergency surgery from savings, insurance is usually the cheaper form of that risk.
What surprises people most?
Dental cleanings under anesthesia ($600–$1,200 every year or two for many dogs) and boarding during travel. Neither shows up in adoption-day budgeting.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
