How it works
Two insurance quotes differ in two numbers: the premium you pay whether or not you claim, and the deductible you pay when you do. Comparing them on premium alone is the mistake that costs people money, because a cheaper quote almost always hides a higher deductible. This tool puts both on one scale — expected annual cost. It takes each premium and adds the deductible weighted by how often you actually claim. If you claim once a decade, a $1,000 deductible contributes about $100 a year to your true cost; if you claim three times a decade, $300. That single adjustment makes a low-premium-high-deductible quote and a high-premium-low-deductible quote directly comparable. The break-even claims line shows the frequency at which the two quotes cost the same: claim more often than that and the lower deductible wins, claim less and the cheaper premium wins. The worst-case figures matter too — the premium plus the full deductible is the most a year can cost you under each quote, and the one whose worst case you can absorb from savings is the safer choice. This only holds when the limits and coverages are identical; a cheaper quote with lower liability limits is a different product, not a better price, so standardise coverage before comparing.Formula
Expected cost = premium + deductible x (claims per decade / 10) | Break-even claims = premium gap / deductible gap x 10
Tips
- Standardise limits and deductibles before comparing — a cheaper quote with lower limits is a different product.
- Estimate claims honestly from your history; most people claim far less often than they fear.
- Choose the deductible your emergency fund can cover without borrowing, then compare premiums at that tier.
- Check the worst case, not just the expected case — the premium plus full deductible is what a bad year costs.
- Re-quote every renewal; carriers raise loyal-customer prices faster than new-customer prices.
