THE FREE ANNUAL PLAN WORKSHEET

Two plans. One year.
A clearer comparison.

Compare the bigger picture: premiums, deductibles, and a care-spending scenario. Keep a copy for your next benefits conversation.

Have the Summary of Benefits and Coverage for each plan ready. This model covers one person, one full year, and a single medical deductible followed by coinsurance.

No signup. Inputs stay in this page and are cleared on refresh. Enter plan amounts only; no medical records or personal details.

Plan A

Monthly premium you pay ($)

Use the same coverage year and any confirmed premium assistance.

Annual deductible ($)

Use the individual in-network medical deductible.

Your coinsurance (%)

Your share after the deductible, not the insurer’s share.

Out-of-pocket maximum ($)

Use the individual in-network limit from the plan document.

Plan B

Monthly premium you pay ($)

Use the same coverage year and any confirmed premium assistance.

Annual deductible ($)

Use the individual in-network medical deductible.

Your coinsurance (%)

Your share after the deductible, not the insurer’s share.

Out-of-pocket maximum ($)

Use the individual in-network limit from the plan document.

Annual covered in-network allowed charges ($)

The insurer-negotiated total before your cost sharing, not the provider's list price or the amount you owe. We apply the same amount to both plans; actual negotiated prices can differ.

Enter all nine amounts, including zeros where appropriate, to see the comparison.

How the calculation works

Annual premiums = monthly premium × 12. Modeled care spending = the smaller of your out-of-pocket maximum and (charges up to your deductible + your coinsurance share of charges above it). Annual total = premiums + modeled care spending.

In the hypothetical example, Plan A has a $300 premium, $4,000 deductible, 20% coinsurance, and $8,000 maximum. At $10,000 in allowed charges, its modeled care spending is $5,200 and annual total is $8,800. Plan B totals $8,600 with the example inputs. At zero charges, Plan A costs less because of its lower premium.

What this worksheet leaves out

Copays, services covered before the deductible, separate prescription benefits, family or embedded deductibles, employer HSA contributions, and midyear enrollment are not modeled. Noncovered and out-of-network care can add spending beyond the displayed limit. Do not use this simplified calculation as a coverage determination or insurance recommendation.

Before you choose

Check that your clinicians and facilities are in each plan's network.
Compare prescription coverage and any separate deductible.
Try several allowed-charge amounts; the lower-cost plan may change.
Confirm premium assistance and benefit details with the marketplace, insurer, or your employer.
