Understanding deductible trade-off — sensitivity table
Everyday editorial team · GEOINNOVATION CO., LTD · Published · Updated
What this calculation is for
A deductible comparison trades a known premium against possible out-of-pocket claims. A cheaper premium is not automatically the lower total cost when a household cannot comfortably fund a large deductible.
How the method works
Each option adds annual premium to the modeled cost of the entered claims, capped at its deductible for each covered claim. The average claim size and claim count make the risk scenario explicit. The displayed model uses: Annual premium + expected claim frequency × min(claim size, deductible exposure) for each option.
A worked example
For an illustrative deductible trade-off scenario, use Annual premium at option A: 1600 $; Annual premium at option B: 1250 $; Option A deductible: 500 $; Option B deductible: 2000 $; Expected covered claims per year: 0.5 claims; Average covered claim size: 4000 $. The modeled lower estimated annual cost is $1,850. These are example assumptions, not current prices, official benefit amounts or personalized advice.
Assumptions and real-world differences
Coverage limits, exclusions, claim frequency, per-event versus annual deductibles and insurer rules can differ. The result is a chosen claims scenario, not a probability-weighted quote. Expected-value comparison only; exclusions, claim severity and insurer pricing are not modeled.
Reading the annual premium at option a sensitivity table
The tool evaluates the same model across a range of annual premium at option a values while holding other assumptions constant. Choose a realistic low value, high value and number of points. Each row reports the same headline measure; the table is a set of conditional calculations, not a probability distribution or a forecast. Input-step rounding can make nearby rows equal.

Sensitivity analysis: 5 comparison points
Annual premium at option A ranges from $800 to $2,400.
- Annual premium at option A: $800: $1,050
- Annual premium at option A: $1,200: $1,450
- Annual premium at option A: $1,600: $1,850
Frequently asked questions
- Why can a claim-size change leave the result unchanged?
- Once the modeled claim already exceeds both deductibles, a larger claim need not increase the deductible amounts paid.
- Which inputs should I check before using this deductible trade-off estimate?
- Check annual premium at option a, annual premium at option b, option a deductible, option b deductible, expected covered claims per year, average covered claim size. Match each field’s unit and time period, then compare the detailed rows rather than treating the headline alone as the complete answer.
- Does the most favorable row show the most likely outcome?
- No. The table assigns no likelihood to any row. It shows how the result responds to the chosen assumption, and you remain responsible for selecting a plausible range.
