Pet Insurance vs Savings Calculator
Compare paying pet insurance premiums against saving the same amount yourself, over your dog's expected lifetime.
Pet premiums commonly rise 10 to 20% a year, and faster after age eight.
What you pay before the policy contributes.

Insurance pays for itself if your dog needs more than about 10,853 of treatment over 12 years. Below that, the savings pot wins. The catch is that you cannot know in advance which side you are on.

What treatments actually cost
| Treatment | Typical range |
|---|---|
| Consultation and basic medication | 60 – 200 |
| Dental extraction under anaesthetic | 400 – 1,200 |
| Foreign body removal surgery | 1,500 – 4,000 |
| Cruciate ligament repair | 3,000 – 6,000 |
| Fracture repair | 2,000 – 5,000 |
| Cancer diagnosis and treatment course | 3,000 – 12,000 |
| Long-term medication, per year | 400 – 2,000 |
Assumptions behind these figures
- Premiums rise every year at the rate you entered. Real policies often rise faster after age eight, and after any claim.
- The savings figure assumes you actually set the money aside every month and never spend it on anything else.
- Savings carry the full risk of one large claim. A cruciate repair or a cancer course can exceed several years of premiums in a single bill.
- Excess, co-payment percentages and annual limits are not modelled beyond the excess figure you entered.
- Insurance usually excludes pre-existing conditions. Self-insuring does not, which matters more the longer you wait to start.
How this is calculated
The comparison runs two parallel scenarios. In one you pay a premium that rises every year. In the other you pay the same amount into savings and earn interest on the balance.
each year:
premium = previous premium × (1 + inflation)
total premiums = total premiums + premium
savings balance = (savings balance + premium) × (1 + interest)
break-even claim = total premiums + total excess paid What the break-even figure means
It is the total veterinary spending at which insurance would have paid for itself. Below that number the savings route wins; above it, insurance does. The difficulty is that you cannot know in advance which side of it your dog will land on.
What treatments actually cost
| Treatment | Typical range |
|---|---|
| Consultation and basic medication | 60 – 200 |
| Dental extraction under anaesthetic | 400 – 1,200 |
| Foreign body removal surgery | 1,500 – 4,000 |
| Cruciate ligament repair | 3,000 – 6,000 |
| Fracture repair | 2,000 – 5,000 |
| Cancer diagnosis and treatment course | 3,000 – 12,000 |
| Long-term medication, per year | 400 – 2,000 |
Compare these against your break-even figure. A single cruciate repair, which is common in several popular breeds and often affects both legs in turn, sits close to a decade of premiums for many owners.
Sources
- Treatment cost ranges are typical published veterinary fee ranges for common procedures and vary widely by region.
- Premium inflation of 10 to 20% a year is the pattern reported across the pet insurance industry. It is not a figure we can attribute to one public dataset, so it is described as a pattern.
What the arithmetic leaves out
The savings column assumes you actually save the money every month for a decade and never spend it on something else. Most people do not. It also assumes the timing works out: a serious illness in year two arrives when the fund holds almost nothing, which is precisely the scenario insurance exists to cover.
Insurance, meanwhile, is not the whole premium in exchange for the whole bill. Excess, co-payment percentages, annual limits and per-condition caps all reduce what you actually get back, and they vary enormously between policies. Compare cover, not just price.
This is not financial advice
We are not licensed to give financial advice and this page does not attempt to. It shows the arithmetic under assumptions you set, so you can see where the crossover falls for your own numbers. The decision depends on your finances and your tolerance for a bad month, and both of those are yours to weigh.
Whichever route you take, decide early. The single most expensive mistake is waiting: insurance bought after a condition appears will never cover that condition.
Common questions
Is pet insurance worth it?
It depends on risk tolerance, not on arithmetic. Insurance is worth it if a sudden four-figure bill would be unmanageable, or if you would find yourself choosing treatment on cost. Self-insuring can come out ahead financially, but only if you genuinely set the money aside and never touch it.
Why do pet insurance premiums rise so fast?
Because claim likelihood rises with age. Increases of 10 to 20% a year are common, and they accelerate after about age eight. That is exactly when you are least able to switch, because any condition your dog has developed becomes pre-existing at a new insurer.
Can I switch pet insurance later?
You can, but anything already diagnosed becomes a pre-existing condition and will be excluded by the new policy. In practice this locks most owners into their original insurer once a dog has any history, which is why premium inflation matters so much.
How much should I save instead of insuring?
At minimum the equivalent premium every month, without exception, from day one. Realistically you also want a buffer of several thousand available immediately, because a serious problem in year two does not wait for the fund to build.
What does pet insurance not cover?
Pre-existing conditions, routine and preventive care, neutering, dental disease in most policies, breeding costs, and often behavioral treatment. Annual limits and per-condition caps matter as much as the premium, and lifetime cover costs more for good reason.
Is it too late to insure an older dog?
Not necessarily, but premiums are much higher, some insurers refuse new policies past a certain age, and anything already diagnosed will be excluded. Self-insuring is often the more realistic route for a dog that has reached middle age uninsured.
