Insurance ROI: what you pay compared with what you could get back
Insurance is an odd thing to measure with return on investment, because the best outcome is usually a negative number. You pay premiums to protect yourself from a loss you couldn't easily absorb. If nothing goes wrong, you get nothing back and that's a good result. The calculator still has a job: it shows what a policy costs over time and what it would take for it to pay off.
Enter your monthly premium, the number of claims you expect over 10 years and the average value of a claim. The calculator totals 120 months of premiums, totals your claims and shows the difference. The example pays $100 a month, or $12,000 over 10 years, and files two $7,000 claims with a $500 deductible. You pay $13,000 in all and get $13,000 back, a 0% ROI.
Change the claim count to zero to see your worst case in dollars, which is also the most likely case for many households. Then find your break-even point, the number of claims at which you get your premiums back. Comparing two policies this way shows you how much extra you're paying for a lower deductible or a higher limit.
Don't use the result to decide whether you need coverage. Insurers set premiums to cover expected claims and their costs, so the average customer pays more than they receive. You're buying protection against the rare, ruinous bill. The calculators below start with typical numbers for car, health and homeowners coverage, and each one explains what moves your costs.
It also counts your deductible on every claim, and tells you what doubling it would take. In the example, a $1,000 deductible adds $500 to each of the two claims, so it only pays off if it cuts your premium by more than $100 a year. The table below runs the same math for common changes. If you'd struggle to pay the higher deductible on short notice, keep the lower one.
How a higher deductible pays off
A higher deductible costs you the difference on each claim. It pays off when the yearly premium savings beat that difference spread over how often you claim.
| Switch | Extra you pay per claim | Savings needed: 1 claim in 10 years | 1 claim in 5 years | 1 claim in 3 years |
|---|---|---|---|---|
| $250 to $500 | $250 | $25 a year | $50 a year | $83 a year |
| $500 to $1,000 | $500 | $50 a year | $100 a year | $167 a year |
| $1,000 to $2,000 | $1,000 | $100 a year | $200 a year | $333 a year |
| $1,000 to $2,500 | $1,500 | $150 a year | $300 a year | $500 a year |
