Two options, one bill assumption
Insurers often price a lower deductible with a higher premium and a higher deductible with a lower premium. This calculator compares those two shapes using the monthly premiums and deductibles you enter, holding reimbursement percent and annual limit constant so the tradeoff is isolated. You also enter assumed claimable bills per year and a horizon in years for cumulative totals.
The lower-deductible option must have a smaller deductible and a higher monthly premium than the higher-deductible option; otherwise the form returns an error so the comparison stays meaningful. Defaults are examples, not recommended settings.
Yearly net and cumulative totals
For each option, yearly net cost equals annual premiums plus estimated out-of-pocket after the same simplified payout math used on other PawMath tools. Cumulative net multiplies that yearly net by the horizon, assuming the same bills every year—an intentional simplification so you can see premium versus deductible tension without inventing a claim-probability curve.
The tool also searches for an approximate claimable-bill level where the two yearly nets cross. Below that level, the cheaper-premium (higher-deductible) option often shows a lower net; above it, the richer deductible can catch up because more of each bill is reimbursed after a smaller deductible. If no crossing appears in the scanned range, the page says so rather than inventing a figure.
Reading the result carefully
Triple-I notes that policies typically include deductibles and caps and that cost depends on the level of care chosen. A household that rarely expects large eligible bills may see the higher-deductible option win on net under these inputs; a household modelling larger bills may see the opposite. Neither outcome is advice. Cash-flow timing also matters: a higher deductible must be payable when care is needed, regardless of multi-year averages.
NAIC highlights that consumers should research terms carefully. Confirm whether the deductible is annual or per incident, whether it resets, and whether separate deductibles apply to different coverage sections. If the two quotes also change reimbursement percent or annual limit, use the plan compare calculator instead of forcing those differences into this two-option tool.
Worked illustration
Suppose the lower-deductible option is $55 per month with a $250 deductible, the higher-deductible option is $40 per month with a $500 deductible, reimbursement is 80 percent, there is no annual limit, and you assume $1,500 of claimable bills. Annual premiums are $660 versus $480. After deductible, bills are $1,250 versus $1,000; payouts are $1,000 versus $800; out-of-pocket amounts are $500 versus $700; yearly nets are $1,160 versus $1,180. Over five identical years the cumulative gap stays small in this invented case—change the bill assumption and the gap moves. Always label your bill figure as an assumption.
