The price was always public.
Nobody opened it.
One actuary and seven AI machines downloaded 48,473 rate filings, took 32,196 of them apart — and rebuilt the prices to the cent. Every price shows the filing it came from.

Every price is free to see. We don't sell insurance.
Rate alerts
Know before your premium changes.
Insurers must file rate changes with your state before they charge them. We read every filing and email you when one affects you.
Checked, not estimated
We prove the math against real prices.
A formula is only worth something if it reproduces what the insurer actually charges. So we test every one against prices it never saw.

How it works
From a state filing to your price.
Read the filing
Before charging anyone, an insurer files its rates with your state. They're public record.
Rebuild the formula
Base rate, age, breed, area, deductible — every factor, in the order the insurer applies it.
Check it
We run it against real prices it never saw. If it doesn't match, it doesn't go live.
Show the source
Every price carries the filing number it came from. You can open the original.

What a quote page won't tell you
The lowest price today isn't the lowest later.

Questions
Do you sell insurance?
No. K.Actuary is not an insurance agency, broker or insurer. We show prices rebuilt from public filings; when you're ready, you buy directly from the insurer.
Where do the prices come from?
From the rate filings insurers submit to state insurance regulators, most of them through the SERFF system. Each price on our site shows the filing number it came from.
How accurate are they?
We test every formula against real prices it was not built from. For pet insurance, 94.3% of 528,183 price options land within 0.2% of the real price. Where a formula doesn't match, we say so and hold the price back.
Will my price be exactly this?
It can differ. Insurers may apply underwriting, discounts or fees outside the filing, and filings change. Treat our number as the filed price, and confirm with the insurer.
Do you need my email or phone number?
Not to see prices — every price is free to see without contact details. We ask for an email address only if you sign up for rate alerts; then we keep your email, state and the lines you picked, and write when a filing affects you. Unsubscribe anytime.
How do you make money?
Comparing prices is free for you. We plan to offer data services to insurers. If we ever receive compensation that could affect what you see, we will disclose it on our Disclosures page.
