Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Annual premium growth | Total premium growth |
|---|---|---|
| $1.5k to $2.5k over 5yr (homeowners) | 10.76% | 66.67% |
| $2k to $3.5k over 6yr (auto) | 9.78% | 75.00% |
| $6k to $9k over 5yr (health family plan) | 8.45% | 50.00% |
| $800 to $1.1k over 4yr (renters) | 8.29% | 37.50% |
How This Calculator Works
Enter the starting and ending annual premium (same coverage on both sides) and the years between them. The calculator finds the compound annual growth rate that connects the two figures.
The Formula
Compound Annual Growth Rate
Start is the beginning value, End is the ending value, n is the number of years
Worked Example
Homeowners insurance rising from $1,500 to $2,500 over 5 years is a 10.8% annual growth rate, total 67%. That's 3x to 4x general inflation — common in catastrophe-exposed states (Florida, California, Louisiana, Colorado) where carrier losses have driven sharp rate cases. Auto and health insurance show similar patterns in different markets.
Key Insight
Insurance premium CAGR varies sharply by line and region. Homeowners in catastrophe-exposed states has seen 10% to 20% annual growth post-2020. Auto insurance industry-wide ran 8% to 15% in 2023-2024 due to repair-cost inflation. Health insurance has historically averaged 5% to 8%. The common thread: insurance premiums tend to outpace general inflation because loss costs (claims paid) outpace it — and rate cases catch up over time.
Why insurance premiums outpace CPI
U.S. insurance CAGR 2014-2024. Health employer family 4.3%. Auto 4.1%. Homeowners 4.0% national (substantially higher Florida 10%+, California 5-8%). General CPI 2.8%.
Drivers HEALTH. (1) Medical cost trend 3-4% baseline.
(2) Specialty drugs (GLP-1s, gene therapies, oncology) substantial mix shift.
(3) Mental health utilization substantially increased post-pandemic.
(4) Aging risk pool.
Drivers AUTO. (1) VEHICLE COSTS. ADAS sensors, EV battery substantial repair cost increases. Avg total loss claim substantially higher.
(2) USED CAR INFLATION 2021-2023. Substantial impact on totaled-vehicle settlements.
(3) LITIGATION. Substantial 'social inflation' jury verdicts.
(4) ACCIDENT FREQUENCY/SEVERITY. Post-pandemic substantial increase distracted driving fatalities.
Drivers HOMEOWNERS. (1) CLIMATE. Substantial hurricane (FL), wildfire (CA), hail (TX), winter storm (TX/Northeast) losses.
(2) REINSURANCE substantial price increases 2022-2024.
(3) REBUILDING COSTS. Lumber, labor substantial inflation.
(4) FRAUD (FL specifically). Roof scams substantially drove insurer losses.
Strategic implications. (1) Shop EVERY renewal. Substantial 10-30% savings switching carriers.
Auto and homeowners — regional dynamics
AUTO PREMIUM by state 2024. Highest: Louisiana $2,800-$3,400/year; Michigan $2,500-$3,200; Florida $2,500-$3,000. Lowest: Vermont, Maine, Idaho $1,000-$1,300.
Drivers. (1) Uninsured motorist rate. (2) Litigation environment (LA, FL substantial). (3) Weather (hail). (4) Urban density.
HOMEOWNERS PREMIUM by state 2024. Highest: Florida $5,000-$10,000+ many counties; Oklahoma $4,000-$6,000 (hail); Texas $4,000-$6,000 (hail, hurricane); Colorado $3,500-$5,000 (hail, wildfire). Lowest: Hawaii, Oregon $800-$1,500.
FLORIDA CRISIS. Substantial 2022-2024 disruption. Multiple major carriers (Farmers, AAA, Bankers) substantially reduced or exited. Citizens (state insurer) substantially largest. Substantial roof age underwriting.
CALIFORNIA CRISIS. State Farm, Allstate substantially paused new policies 2023-2024. Wildfire risk. FAIR Plan substantially grew.
Strategic responses. (1) BUNDLE. Auto+home substantial 10-20% multi-policy discount.
(2) RAISE DEDUCTIBLES. $1,000 → $2,500 substantial premium reduction.
(3) ACTUALLY SHOP. Substantial loyalty premium most carriers.
(4) MITIGATION. Roof straps (FL), defensible space (CA), water sensors substantial discounts.
(5) NON-RENEWAL PLAN. Substantial Florida/California homeowners. Have backup carriers identified.

Frequently Asked Questions
How is insurance premium CAGR calculated?
(Ending premium / starting premium) ^ (1/years) − 1. From $1,500 to $2,500 over 5 years is about 10.8% per year.
How fast do insurance premiums typically grow?
Long-run averages: 5% to 10% per year across most lines. Sharp acceleration in catastrophe-exposed regions (Florida, California, Louisiana, Colorado wildfire areas) where rates have grown 15% to 30% annually in recent years. Health insurance steadier around 5% to 8%.
Why do premiums grow faster than inflation?
Loss costs (medical bills, vehicle repair, home rebuild cost) inflate faster than general CPI. Insurance pricing reflects expected loss costs plus expense load — when loss costs accelerate, premiums catch up after a lag through rate cases.
Can I lower the growth rate?
At individual policy level: raise deductibles, drop or limit coverage, shop carriers annually, bundle policies, improve credit score (in states where it affects insurance). Market-level rate trends are largely outside any individual customer's control.
Should I project at this rate forward?
Use recent CAGR for short-horizon budgeting (1 to 3 years), but expect mean reversion over longer periods — current double-digit homeowners growth in cat-exposed states won't continue indefinitely. Use long-run line-and-region averages (5% to 10%) for 5+ year projections.
When is this calculator unreliable?
Less reliable when coverage changed mid-period (added drivers, raised dwelling limits, changed plan tier), when credit-based scoring shifted, when regulatory changes occurred (Florida 2022-2024 substantial homeowners disruption), or when claims history changed (1 claim can drive 10-30% increase or non-renewal).

Methodology & Review
Insurance premium CAGR = (ending/beginning)^(1/years) − 1. Returns compounded annual growth rate. U.S. employer health family premium 2014-2024: $16,834 → $25,572, ~4.3% CAGR (KFF). Auto insurance 2014-2024: ~50% cumulative, ~4.1% CAGR. Homeowners: ~50% cumulative, ~4% CAGR with substantial regional variation (Florida, California much higher). RELIABILITY: Reliable for like-for-like coverage (same deductibles, limits, networks, household composition). Less reliable when (a) coverage changed mid-period (added drivers, increased dwelling limits, changed plan tier); (b) credit-based scoring shifted; (c) regulatory changes (Florida 2022-2024 substantial homeowners disruption); (d) claims history changed.
