Short-Term Health Plan Cost Estimator

About the Short-Term Health Plan Cost Estimator

Short-term health insurance (STHI) provides temporary coverage for gaps between major medical plans. These plans are significantly cheaper than ACA-compliant coverage ($100–$200/month vs $400–$800+) but come with substantial limitations: pre-existing condition exclusions, benefit caps, and limited coverage.

STHI is designed as a bridge, not a long-term solution. Plans typically last 3–12 months and may be renewable for up to 36 months in some states. They're popular among people between jobs, aging off parents' plans, or waiting for employer coverage to start.

This calculator compares the cost and effective coverage of a short-term plan versus an ACA marketplace plan. These are educational estimates only and not actual insurance quotes.

When This Page Helps

Short-term plans are tempting because of low premiums, but their coverage gaps create hidden financial risk. This calculator quantifies what you're actually getting for your premium dollar versus a comprehensive ACA plan.

How to Use the Inputs

1. Enter the short-term plan monthly premium.
2. Enter the plan's deductible and coverage limit (benefit cap).
3. Enter the ACA marketplace plan premium and your tax credit.
4. Enter the ACA plan's deductible and out-of-pocket maximum.
5. Enter the number of months you need gap coverage.
6. Compare total costs and worst-case exposure.

Example Calculation

Tips & Best Practices

• Short-term plans DO NOT cover pre-existing conditions — any condition diagnosed in the past 2–5 years is excluded.
• STHI doesn't count as minimum essential coverage — no penalty currently, but no ACA protections either.
• Some states ban or heavily regulate short-term plans (CA, MA, NY, NJ, and others).
• If you're between jobs, a marketplace plan with subsidy may cost the same or less with far better coverage.
• These are educational estimates only, not insurance quotes.
• Always read the short-term plan's exclusions carefully — they're extensive.

When Short-Term Plans Make Sense

The ideal short-term plan candidate is a healthy person needing 1–3 months of catastrophic coverage between jobs or other qualifying events. In this narrow scenario, the low premium provides peace of mind against major unexpected events without the cost of a full ACA plan.

The Hidden Cost of Coverage Gaps

Short-term plans' exclusions create hidden costs. A seemingly cheap $150/month plan can leave you with tens of thousands in uncovered bills if a pre-existing condition flares up or you need maternity care. The total cost of ownership (premium + uncovered expenses) often exceeds an ACA plan's cost.

Making the Decision

Before choosing STHI, always check: (1) ACA marketplace with subsidies — you may qualify for near-free coverage, (2) Medicaid eligibility — especially if income is low during the gap, (3) COBRA — expensive but comprehensive, (4) healthcare sharing ministries as another alternative. Short-term should be the last resort, not the first choice.

Frequently Asked Questions

• What do short-term health plans cover?

  STHI covers unexpected accidents and new illnesses (like broken bones, appendicitis, or infections). Most plans cover doctor visits, hospital stays, surgery, ER visits, and labs. They do NOT cover pre-existing conditions, maternity, mental health, prescription drugs (usually), or preventive care.

• What are the biggest risks of short-term plans?

  The main risks are: (1) pre-existing condition exclusions mean any prior health issue isn't covered, (2) benefit caps ($250,000–$1M) leave you exposed for catastrophic events, (3) no coverage for maternity, mental health, or prescriptions, (4) insurers can rescind coverage if they find undisclosed conditions. These gaps can leave you responsible for tens of thousands of dollars in unexpected medical bills. Always read the plan's exclusions and limitations carefully before purchasing.

• How long can I keep a short-term plan?

  Federal rules allow plans up to 364 days, renewable for up to 36 months total. However, some states limit duration to 3–6 months with no renewal. Check your state's regulations. Renewal doesn't guarantee the same rates — conditions developed during the plan may be excluded upon renewal.

• Is short-term insurance right for me?

  STHI may be suitable if: you're healthy with no pre-existing conditions, you need coverage for a specific short gap (1–3 months), you don't qualify for ACA subsidies, and you understand the coverage limitations. It's NOT suitable for ongoing medical needs or anyone with pre-existing conditions.

• Can I buy short-term insurance after missing ACA open enrollment?

  Yes, STHI has no enrollment periods — you can buy it anytime. This is one reason people turn to it after missing ACA open enrollment. However, check if you qualify for a Special Enrollment Period first (job loss, marriage, moving, etc.), as an ACA plan would be better.

• Do short-term plans cover prescriptions?

  Most STHI plans have very limited or no prescription coverage. Some offer a small discount card. If you take regular medications, the out-of-pocket drug costs can easily exceed the premium savings compared to an ACA plan that includes prescription coverage.
