## How it calculates

For each plan, the optimizer computes total annual cost at every spending level using the following formula:

Total Effective Cost = Annual Premium + Out-of-Pocket Medical Costs - HSA Tax Savings

The out-of-pocket medical cost is calculated as: min(spending, deductible) + max(0, (spending - deductible) * coinsurance rate), capped at the plan's out-of-pocket maximum. This means you pay dollar-for-dollar until you hit your deductible, then you split remaining costs with your insurer at the coinsurance rate, and once you hit your OOP max the insurer covers everything else.

For HDHP plans, the calculator estimates HSA tax savings by multiplying the lesser of your out-of-pocket medical costs or the IRS HSA contribution limit ($4,150 for individuals in 2024) by your marginal tax rate. This reflects the real tax benefit of paying medical expenses with pre-tax dollars through an HSA.

Crossover points are found by sweeping through spending levels in $250 increments from $0 to $55,000 and detecting where one plan's cost curve crosses another. These crossover points tell you the exact healthcare spending threshold where switching plans would save money.

## Who should use this

Employees evaluating health insurance options during open enrollment who want to make a data-driven decision rather than guessing which plan is cheapest. Freelancers and self-employed individuals shopping for marketplace plans who need to compare Bronze, Silver, and Gold tier options. Families planning for known medical expenses such as a pregnancy, surgery, or ongoing treatment who want to model costs under different plans. HR professionals and benefits consultants helping employees understand the true cost differences between plan options. Anyone considering a switch from a traditional plan to a High-Deductible Health Plan who wants to understand whether the HSA tax savings offset the higher deductible.

## Worked examples

Example 1: An employee chooses between a Silver PPO ($350/month premium, $2,000 deductible, 20% coinsurance, $6,000 OOP max) and an HDHP ($200/month premium, $3,000 deductible, 30% coinsurance, $7,000 OOP max). They expect $5,000 in healthcare spending and are in the 22% tax bracket.

Silver PPO: Annual premium = $4,200. Out-of-pocket = min($5,000, $2,000) + ($5,000 - $2,000) * 0.20 = $2,000 + $600 = $2,600. Total = $6,800.

HDHP: Annual premium = $2,400. Out-of-pocket = min($5,000, $3,000) + ($5,000 - $3,000) * 0.30 = $3,000 + $600 = $3,600. HSA savings = $3,600 * 0.22 = $792. Effective total = $2,400 + $3,600 - $792 = $5,208.

The HDHP saves $1,592 per year at this spending level.

Example 2: A healthy individual expecting only $1,000 in spending compares a Gold plan ($500/month, $500 deductible, 10% coinsurance, $4,000 OOP max) to a Bronze plan ($250/month, $5,000 deductible, 40% coinsurance, $8,000 OOP max). Gold total = $6,000 + $500 = $6,500. Bronze total = $3,000 + $1,000 = $4,000. At low spending, the Bronze plan wins by $2,500.

## Limitations

This calculator models a simplified version of health insurance cost-sharing. Real plans may have separate deductibles for in-network and out-of-network providers, drug-specific formulary tiers with different copays, and varying coinsurance rates for different service categories. Copays for specific visit types are not factored into the spending scenarios. The HSA tax savings calculation uses only federal marginal rates and does not account for state income tax savings or FICA tax savings, which would make HDHP plans look even more favorable. The tool assumes all spending is in-network. Actual insurance premiums vary by age, location, family size, and employer contribution, which this tool does not model since users input their own premium amounts. Plans with embedded copay structures before the deductible are not perfectly modeled by the deductible-then-coinsurance formula.

## FAQs

**Q:** What is coinsurance and how does it differ from a copay?


**A:** Coinsurance is a percentage of costs you pay after meeting your deductible. If your coinsurance is 20%, you pay 20% of covered services and the insurer pays 80%. A copay is a fixed dollar amount you pay per visit, regardless of the total cost.


**Q:** What is an out-of-pocket maximum?


**A:** The OOP max is the most you will pay for covered services in a plan year. Once you reach this amount, your insurance covers 100% of remaining costs. Monthly premiums do not count toward the OOP max.


**Q:** How do HSA tax savings work?


**A:** If you have an HDHP, you can contribute pre-tax dollars to a Health Savings Account. Money goes in tax-free, grows tax-free, and comes out tax-free for qualified medical expenses. At a 22% tax bracket, every $1,000 you put in an HSA saves you $220 in federal taxes.


**Q:** Should I always pick the plan with the lowest premium?


**A:** Not necessarily. A low-premium plan with a high deductible can cost more overall if you use a moderate amount of healthcare. This tool helps you find the true lowest-cost plan at your expected usage level.


**Q:** What counts as a High-Deductible Health Plan?


**A:** For 2024, an HDHP must have a minimum deductible of $1,600 for self-only coverage or $3,200 for family coverage, and the out-of-pocket maximum cannot exceed $8,050 (self-only) or $16,100 (family).
