## How it calculates

The tool uses compound growth to project future premiums. The core formula is:

Future Premium = Current Premium x (1 + Inflation Rate) ^ Years

Where the inflation rate is expressed as a decimal (e.g., 7% becomes 0.07). This is the same exponential growth formula used in compound interest calculations, applied here to premium costs rather than investment returns.

Default annual inflation rates by insurance type are based on historical averages:
- Health insurance: 7.0% per year
- Auto insurance: 4.0% per year
- Homeowners insurance: 6.0% per year
- Life insurance: 2.5% per year
- Dental insurance: 4.0% per year
- Vision insurance: 3.0% per year

The cumulative total paid is calculated by summing each year's projected premium. The year-over-year increase for any given year equals that year's premium minus the prior year's premium. The total inflation percentage is the percentage increase from the current premium to the final year's premium. The cost multiplier shows how many times larger the final premium is compared to today's premium.

## Who should use this

This tool is useful for several groups of people. Individuals planning for retirement should understand how insurance costs will grow over the decades ahead, especially health insurance premiums which can compound significantly over a 20-year horizon. Families budgeting for long-term expenses benefit from seeing the cumulative total they will spend on insurance over the coming years. Financial planners advising clients on retirement readiness can use the projections to ensure adequate savings for rising insurance costs. Small business owners projecting employee benefit costs over multi-year planning horizons will find the year-by-year breakdown valuable. Anyone comparing insurance types can see how different categories of coverage inflate at different rates, which is relevant when deciding how much coverage to carry or where to focus cost-reduction efforts.

## Worked examples

Example 1: A 45-year-old pays $8,400 per year for family health insurance. She wants to know what her premiums might look like when she turns 65.

Input: $8,400 current premium, health insurance type, 20-year projection.
Using 7% annual inflation:
- Year 1 premium: $8,400 x 1.07 = $8,988.00
- Year 10 premium: $8,400 x 1.07^10 = $16,525.49
- Year 20 premium: $8,400 x 1.07^20 = $32,503.16
- Total paid over 20 years: approximately $344,251
- Cost multiplier: 3.87x (the premium nearly quadruples)

Example 2: A homeowner pays $2,400 per year for homeowners insurance and wants to see costs over the next 10 years.

Input: $2,400 current premium, home insurance type, 10-year projection.
Using 6% annual inflation:
- Year 1 premium: $2,400 x 1.06 = $2,544.00
- Year 5 premium: $2,400 x 1.06^5 = $3,211.69
- Year 10 premium: $2,400 x 1.06^10 = $4,297.12
- Total paid over 10 years: approximately $31,645
- Without inflation, total would be $24,000, a difference of about $7,645

Example 3: Using a custom inflation rate. An auto insurance policyholder currently pays $1,800 per year but expects 6% annual increases due to rising repair costs.

Input: $1,800 current premium, auto insurance type, 15-year projection, 6% custom rate.
- Year 15 premium: $1,800 x 1.06^15 = $4,313.47
- Cost multiplier: 2.40x

## Limitations

This tool uses a single constant inflation rate applied uniformly across all years. In reality, insurance premium inflation is not smooth. Some years might see 2% increases while others see 15% jumps, especially in health and homeowners insurance after catastrophic events or regulatory changes. The tool does not account for age-related premium adjustments; health and life insurance premiums often increase with age independently of general inflation. Policy changes such as increased deductibles, reduced coverage, or switching carriers can significantly alter actual premium trajectories. The default inflation rates represent broad historical averages and may not reflect your geographic area, specific insurer, or current market conditions. This calculator does not factor in employer contributions for employer-sponsored insurance. It also does not account for potential policy lapses, coverage changes, or the effect of shopping around for better rates.

## FAQs

**Q:** Where do the default inflation rates come from?


**A:** The default rates are based on historical averages observed in the U.S. insurance market over the past two to three decades. Health insurance has consistently been among the fastest-rising categories. These are approximate figures meant for planning, not precise actuarial projections.


**Q:** Should I use the default rate or enter a custom rate?


**A:** Use the default rate if you want a general projection based on typical market trends. Use a custom rate if you have specific knowledge of your insurer's pricing trends, live in a region with above-average or below-average increases, or want to model best-case and worst-case scenarios.


**Q:** Does this account for switching to a cheaper plan or changing deductibles?


**A:** No. The tool projects growth from a fixed starting premium using a constant rate. If you change your coverage level, your actual premium trajectory will differ. You can re-run the calculation with a new starting premium to reflect a plan change.


**Q:** Why does health insurance inflation seem so high compared to general inflation?


**A:** Health insurance premiums reflect not just general price inflation but also increased utilization of medical services, advances in medical technology, prescription drug costs, and regulatory requirements. These factors have historically driven health insurance costs up faster than the Consumer Price Index.


**Q:** Can I use this for monthly premiums?


**A:** Enter your annual premium (monthly times 12). The projections are calculated on an annual basis. Divide any annual figure by 12 to get the monthly equivalent.
