Understanding deductible trade-off — two-scenario comparison
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.
Building two independent scenarios
Scenario A and Scenario B each have a complete set of inputs for this deductible trade-off calculation. Change several inputs in B when comparing genuinely different plans, then inspect the B-minus-A headline difference and the detailed rows. When multiple inputs change, the total difference cannot be attributed to just one of them.

- Scenario A — Annual premium at option A
- 1,600 $
- Scenario A — Annual premium at option B
- 1,250 $
- Scenario A — Option A deductible
- 500 $
- Scenario A — Option B deductible
- 2,000 $
- Scenario A — Expected covered claims per year
- 0.5 claims
- Scenario A — Average covered claim size
- 4,000 $
- Scenario B — Annual premium at option A
- 2,000 $
- Scenario B — Annual premium at option B
- 1,250 $
- Scenario B — Option A deductible
- 500 $
- Scenario B — Option B deductible
- 2,000 $
- Scenario B — Expected covered claims per year
- 0.5 claims
- Scenario B — Average covered claim size
- 4,000 $
Scenario B result: $2,250
Scenario A: $1,850. Lower estimated annual cost.
- Scenario A main result: $1,850
- Scenario B main result: $2,250
- Numeric difference (B − A), in result units: 400
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.
- Why is this different from the one-factor comparison?
- The one-factor tool changes only annual premium at option a. This version lets all model inputs differ, so it is more flexible but does not isolate the effect of any single change.
