One caveat worth knowing: home premiums track rebuilding costs — labour, materials, and local claims — more closely than they track general consumer prices, and those often run hotter than CPI. Treat these as a floor, not a verdict.

Benchmark is your adjustable assumption — not a rate forecast
Time to get quotes. Your renewals tripped growth 5+ points above your benchmark and cumulative excess over 20% of your baseline premium — our rule of thumb for when comparison shopping is most likely to pay off. Match coverage limits when you compare.
How to use
- Enter your annual premium for each renewal year, oldest first (it's on each year's declarations page).
- Adjust the inflation benchmark if you want a stricter or looser comparison — 3% is a common long-run assumption.
- Read the ledger: year-by-year change, what you'd pay on the benchmark track, and the excess — then check the shop-around verdict.
How it works
Premiums rarely jump once — they creep. A few percent here, a "rate adjustment" there, and five years later you're paying half again what you started at without ever deciding to. This tool makes the creep visible.
It computes your premium's compound growth rate (P_n/P_0)^(1/n) − 1 and lays an inflation track next to your actual payments: P_0·(1+i)^t with a benchmark you control. The gap between the two, summed across years, is the dollars your premium grew beyond ordinary inflation — the number that tells you whether shopping around is likely to pay for the afternoon it takes.
By design, this calculator uses no rate tables — nothing here goes stale. All calculation happens in your browser and your numbers never leave your device.
Frequently asked questions
Why did my home insurance go up?
The usual drivers are rising rebuilding costs (labor and materials), weather and catastrophe losses in your region, claims on your policy or in your area, and coverage limits that increase automatically with inflation adjustments. This calculator doesn't diagnose which one applies to you — it measures how fast your premium is actually growing, so you can decide whether it's worth acting on.
What percentage increase is normal for home insurance?
There is no single normal — it varies by state, carrier, and year. That's why this tool compares your premium against an inflation benchmark you control instead of a rate table that goes stale. Growth roughly tracking inflation is unremarkable; growth persistently 5+ points above it is worth questioning.
What inflation benchmark should I use?
The reference table in the tool gives you two anchors for five major markets, and clicking a figure fills the field. The steadier choice is your central bank's target (2% in the US, UK, Canada and the euro area; 2–3% in Australia) because targets almost never change. The alternative is the latest published annual CPI, which moves every month. One honest caveat: home premiums track rebuilding costs — labour, materials, and local claims — more closely than general consumer prices, and those often run hotter than CPI, so treat either figure as a floor rather than a verdict.
When should I shop around for home insurance?
Consumer guidance from the Insurance Information Institute and state regulators recommends comparing quotes regularly — at renewal is the natural moment. Our verdict uses three disclosed rules of thumb: a single-year jump of 15%+, sustained growth 5+ points above your benchmark, or cumulative excess above 20% of your baseline premium.
Does getting insurance quotes hurt my credit score?
Insurance quotes typically use a soft inquiry for credit-based insurance scoring, which does not lower your credit score the way a hard inquiry can. Practices vary, so you can ask the insurer before quoting.
How do I compare quotes fairly?
Match the coverage: same dwelling limit, deductible, liability limit, and endorsements. A cheaper quote with a higher deductible or lower dwelling coverage isn't a like-for-like saving — it's a different product.
Can I lower my premium without switching insurers?
Often, yes: raising your deductible, bundling home and auto, asking about discounts (alarms, roof age, claims-free), and reviewing coverage you no longer need are the standard levers — see the III's list in the sources below.
