Now use a fictional policy that pays 80% after subtracting a $500 annual deductible, with an unused $8,000 annual payout cap. Assume all services are eligible, no smaller cap applies and no other claim consumes benefits. Compare it with the identical calculation without that annual cap. Premiums are separate, and neither model is a named insurer’s offer.
| Same care at different prices | Payment under $8,000 cap | Owner share with cap | Owner share without annual cap |
|---|---|---|---|
| $8,000 starting basket | $6,000 | $2,000 | $2,000 |
| $10,000: prices 25% higher | $7,600 | $2,400 | $2,400 |
| $12,000: prices 50% higher | $8,000 | $4,000 | $2,800 |
At $12,000, the uncapped calculation is 80% of $11,500, or $9,200. The fixed cap removes $1,200 of that payment. The capped owner share has doubled from the starting $2,000 even though the care basket rose by half and no policy setting changed.
In this model the cap begins restricting payment once eligible charges exceed $10,500. That is only 31.25% above the starting basket. Beyond that point, an extra dollar of eligible care leaves an extra dollar with the owner for the rest of the exhausted allowance; before the cap binds and after the deductible is met, the retained increment is 20 cents. This is why small remaining headroom deserves attention.
